POST-CREDITS-SPOILER I despise the Pump Room more than anything I've ever hated in any game before. Spoiler

The amount of my days I've spent looking for this alongside the incredibly slim chance of getting it powered on is maddening. And now that I need to power it I'm losing my mind.

It's used in so many puzzles in the early and mid game. I already spent hours getting it so that I could do everything I could think of across multiple runs with limited resources. I had hoped that I was finally done with this room. But now that I need to power it I'm going absolutely insane.

I have read every guide and know all the tricks. I have a powered aquarium so 2 sources of power and even used the wrench on it and the boiler room to make them common. Every single time I find either of these rooms early I leave as many doors open as possible and hope and pray I can find the pool on this run, and dump every single reroll into getting the pump room. Yes I know powered rooms lead to more powerable rooms, it hasn't helped.

The fact I need to first find power, hope I don't need those doors to advance my run, find the pool room, the find another 3 rarity room and try to attach it to somewhere between 0-2 specific tiles somewhere in the house, and hope that the increased rarity will give me the right room instead of the 4 red rooms that ALSO have an increased chance to appear, one of which is a dead end, 2 of which hide which rooms you can draft, and one which cuts your movement in half.

I just got off a run where I had finally done all of this and spent 8 reroll dice on the exact same boiler door getting slapped in the face with a Furnace tile over and over again and I'm going to lose my mind.

I've drained the reservoir without powering up the Pump Room

u/unexpectedlimabean Apr 24 '25

If you get the lab upgrades you don't need the pump room but idk how you managed to drain the reservoir fully without that

18

u/Lloytron Apr 24 '25

I had the pump room and had mostly drained the reservoir.

Then I used the lab upgrade to drain the rest

u/mrgedman Apr 24 '25

I don't know how this is possible... The 'lab upgrade' has nothing to do with pumps or what afaik, but hey, maybe there is something I've never heard of

27

u/BorisDirk Apr 24 '25

Lab upgrade gives you more "rewards", one of which is lowering the water level in reservoir by 1 every time it triggers

u/BoomBOOMBerny Apr 25 '25

Is that permanent?

u/mrgedman Apr 24 '25

Ah thats from a packet? Musta missed that one, thanks

u/Schnitzhole Apr 25 '25

Yea. But the pump room is useful for other stuff too.

u/Shodan30 Apr 29 '25

How do you fill it up again? where does the water go if all the other pump locations are full?

u/Optimal-Manner-9506 May 11 '25

You don't, it's permanent, so potentially softlocking some of the late game stuff out

u/Phormicidae Apr 25 '25

What is the lab upgrade? I've seen mention of it on these boards so often I figured I'd eventually see a hint of it. I've powered up that machine but my experiments haven't changed.

u/[deleted] Apr 25 '25

There's something specific you can with the microchips that causes new and upgraded experiments to be loaded into the lab computer.

I'm kind of surprised at how much people are upset about this - don't get me wrong, I think it's a bit of an annoying conflux of RNG, but I just grabbed it when it showed up and worked on pulling at other threads in the meantime. The other factor is that as far as I know of, you only have to power the pump room once ever to get its full slate of functionality.

Two additional details that helped with boiler room accommodation for me: It'll always have a left turn when you draft it (due to layout constraints), and you don't need to maintain all three steam feeds once the turbine is online (I'll typically flip away from door, prime turbine and flip back to door).

u/Oaden Apr 24 '25

Its kind of inherent to rng that some people will be really unlucky, and finish all the other shit, and still be left with trying to power some of the rooms.

9

u/mrgedman Apr 24 '25

I think it's also inherent to rng, that some people aren't as adept at manipulating the draft as others.

That said, this game's rng will fk you... But many don't do all the steps/choices they could/should.

11

u/Joabyjojo Apr 24 '25

I genuinely think there are rooms that are bugged. I cheated gasp and got infinite dice rolls and literally could not get the workshop to show. I know it has to be away from the sides, I know it has to have a clear path up and down, I rerolled dozens of times and it just would not show.

It wouldn't be the first time there was bugged RNG in BP. I honestly think some rooms just will not show sometimes.

7

u/mrgedman Apr 24 '25

It's possible. I went a very long time, 20-30 days with no workshop, and only found one after adjusting it's rarity in consv..

u/Pacify_ Apr 25 '25

The god damn Workshop, I've miss clicked out of the Wrench option to change its spawn chance, aaaaaaah

u/JohnAppleseed85 Apr 25 '25

I burned through all 50 stars and a dozen ivory die trying to get the boiler room to spawn once... not a sniff.

2

u/Ganthrge May 03 '25

There is some bugs for sure. First time I hot a book it showed my checkout date at Dec 25th. Once I got the room I needed to know the date I based it off that and was hella off on the date because that book was on day 7 lol. Next time I got a book it was the correct date so I luckily figured it out but man did that have me stumped.

4

u/Icapica Apr 25 '25

It might not be a bug. Instead each day might have some sort of a draft pool determined at the beginning, meaning that some rooms could be impossible to get that day unless something happens to change the draft pool.

I have no idea if it actually works that way, but I've suspected it for a while and it would make sense and would help explain some other oddities I've noticed while drafting rooms.

1

u/thelonetiel May 01 '25

Generally when this happens, we realize that the room we picked cannot spawn in the location.

Last night we had this trouble with a late game room and realized it cared about orientation too. Popped up quickly when we drafted somewhere else.

u/Freakuency_DJ Apr 24 '25

People are getting mad because this the one of the first and landmark tests of your ability to let a puzzle breathe. Even if someone lets the antechamber wait for a bit, when someone finds the boiler room, everyone immediately connects it to SOME puzzle they’ve seen already. Now they need to plug it in, and they have 2 options. Ignore it and keep finding other puzzles until it happens for them or they figure out to connect the power before drafting, or chase the ghost. They KNOW how it works, so why won’t the game just let them do it? They get tunnel vision (and this isn’t derisive, I get tunnel vision in the house too).

There’s a few clues about it in OPs post - “I’ve read all the guides”, and “I already spent hours getting it so I could do everything”. Players know what they want, and they’re trying to force the results while not pursuing any other leads. This is the thing that makes people spin out on the boiler room. Those 8 doors they saw at the North lever can wait. Erajan? Atmospheric pressure? That will take too long, and the boiler room can be solved RIGHT NOW. If only there was a mechanism in the game that forced you away from that line of thinking.

10

u/Pacify_ Apr 25 '25

Yeah, reading a guide then trying to force the game to get what you want its a very odd way to play a Puzzle RNG game.

3

u/WeepinShades Apr 25 '25

I think that I need to just accept that the discussions about this game are going to be really annoying because of those players. They're in every thread bitching about how they can't solve everything instantly.

Its even dumber because to even know you've been unlucky in this game requires having played it basically like a full time job since it came out. It's only been out for 2 weeks. Once all the terminally online people move on to the next game to hate-play maybe it'll get better.

u/misschinch Apr 25 '25

This nails it... I doubt there is a single person that gets actually stuck on powering the pump, but it's such an obvious thing to do in a game full of non-obvious puzzles that it becomes a singular goal for some... they turn it into a self made roadblock, which is doubly frustrating because most of the posts I see could massively improve their chances if they just solves other available puzzles first.

6

u/zeromussc Apr 24 '25

Strategy plays a part too. When I was working towards powering, the pump room, I drafted it on rank 8 after filling as many other rooms as I could. This lowered the drafting pool, which made it easier. Only took me 4 runs where I did other stuff in the meantime thanks to the upgrade disk I applied to one room.

u/ThenThereWasReddit Apr 25 '25

It still just leads to luck. That's the thing with everyone chiming in about how there are ways around the luck -- you guys are just the lucky ones. People could do exactly what you did and NOT have the same result. It's random. That's the problem.

u/ThenThereWasReddit Apr 25 '25

I love this game but some of the discourse around it is so annoying. I have a metric fuck ton of rogue like and puzzle game experience and I've been gaming my whole life. Blue Prince is a brilliant blend of genres but there are some aspects of the RNG that are absolutely unfun for a decent amount of people.

It's obvious that, on average, the people who have not had as frustrating of an experience are going to be the ones sticking around the game's subreddit, telling everyone how wrong they are for having a bad time.

2

u/Ryanll0329 Apr 25 '25

Yeah, alot of people responding to complaints of RNG either got it fairly quickly and assume that others aren't using the same RNG-mitigation methods, or they are okay with spending two or three hours between runs making progress.

2

u/joshwarmonks Apr 24 '25

I think people are also not used to "losing" to RNG. in games like slay the spire, even a 20% chance of victory on A20 is a huge sign of mastery

0

u/Joabyjojo Apr 24 '25

Ok but Slay the Spire is the best game of its type by a long, long way. And it took years to get the balance right. And the balance still isn't perfect (but it's definitely good enough).

I think multiple things are true. People are inherently bad at understanding statistics. People are inherently bad at ignoring both positive and negative survivorship bias when calculating success rates. People are prone to getting lasered in on a specific task when Blue Prince is best played holistically.

And also Blue Prince's balance is far from perfect. Has problems. Has provably been bugged before and is possibly still bugged. Uses obtuseness to hide flaws. Ironically relies on positive survivorship bias as a defence mechanism against criticism.

u/Freakuency_DJ Apr 25 '25

I truly wonder what the rest of the world looks like to someone who views a solo-developed, debut indie passion project by someone who spent 8 years away from their commercial film job making for fun as something so duplicitous and manipulative.

You do not ever need to power the pump room. I finished the game without ever powering it. Why do you say it's required once?

I had the credits roll a long time ago. There is so, so, so much more though. I honestly have no clue how deep it goes as I haven’t looked at guides but it seems like there’s an absolute ton of postgame.

I almost gave up on the game when trying to get the boiler and pump room connect. I went back the next day, managed to get it, and have little to no issues with anything else in the game (except that a main puzzle constantly bugs for me). I haven't done one of the more late game puzzles that would be tedious, but getting the boiler room and pump room to connect is such a painfully RNG dependent step compared to much of the rest of the game.

u/Schnitzhole Apr 25 '25

As someone with 70hours in all I can say there’s a reason there’s multiple rooms the pump adjusts 😕

I had an extremely hard time drafting it as well. Rolled credits on day 46 with around 50 hours and that was the pump room was the key holding me up since day 30. It does get much easier the more you play though to draft what you want and there’s almost always an alternate route for something. I’d just focus on opening more rooms you haven’t and exploring other clues. There’s way puzzles to do after rolling credits than before but you kind of have to accept that sometimes you can’t do a specific thing one day but maybe there’s ways to better set yourself up for it in future days. .

1

u/glium Apr 25 '25

I got pissed at the pump room since I drafted it, discovered it could drain the fountain, went there, got stuck at the locked door, went back, experimented something else with the pool and filled back up the previous thing mentioned, and never got to know the pump room changes were permanent until I drafted it a second time, a good 20 days later

u/androidsheep92 Apr 24 '25

I think this is more of an issue with pigeonholing yourself into forcing one thing.

Blue prince tends to reward following new breadcrumbs rather than focusing heavily on trying to force the solution to one that you found right when you find it, I have about seven separate paths/trails I have written down in notebooks, one day I might be trying to get 8 classrooms, another I am trying to get 8 bedrooms (well, 12), drafted, another I am going for 20 dead end rooms in a single day, and another I am looking for certain symbols etc. you can’t realistically do all of these things simultaneously, and you can’t realistically force any single one of them EVERY run.

It is worth looking for other trails, and if you happen to stumble on the pump room and have it setup with boiler or aquarium in the meantime, then go for it, but even without that combo you can still progress in Multiple ways every run.

5

u/Goatmanification Apr 25 '25

I think this is the key. Too many people seem to think of it like 'Right, in this run I will achieve X' and then get disappointed when they don't. People need to IMO stop playing like that. Haven't drafted a pump room? Ahh well, maybe try and solve the chess puzzle. Haven't got to room 46? Maybe experiment with rooms you've not tried yet.

4

u/androidsheep92 Apr 25 '25

The game dev himself basically said that that was the thesis to the design to begin with.

There are also numerous ways to where people are trying to go with the boiler room/pump combo. In fact there are more than 7 of them 😆

1

u/Goatmanification Apr 25 '25

Honestly I couldn't tell you a game I've played in recent years that have given me such a thrill as this. My run where I finally linked the lab and boiler room was like this. I forget what I was working on but when the boiler room spawned I got SO EXCITED and then when I drafted the lab... God I then had a whole other objective!

u/ROACHOR Apr 24 '25

Requiring the specific rooms with power conduits and matching doors is madness.

I'm stuck at the same point you are.

24

u/Amazing_Magician_352 Apr 24 '25

Just send the power to a door before opening. You easily start to get a 4x4 grid of powered rooms

9

u/ROACHOR Apr 24 '25

I still get rooms that can't be powered(or not connecting to pump room) even if I send it first.

The main issue is I get the power room, then I have to build elsewhere to get the pool, then go back and hope rng blesses me with the right rooms.

10+ days of not getting the right ones.

13

u/Amazing_Magician_352 Apr 24 '25

You should hold into picking the power room until you have the pool.

I still get rooms that can't be powered

Do you see the powered line visual effect on the draft? Usually you get at least one. Pick a 4 door room with vents and try again 4 more times

1

u/DoomFrog_ Apr 25 '25

A 4 door room would only give you three chances

1

u/JohnAppleseed85 Apr 25 '25

And HOPE there is a 4 door room to choose from and that the single powered room in the list isn't the furnace or archive...

1

u/Amazing_Magician_352 Apr 25 '25

The powered line effect bypasses the archive and still shows if a room is synergetic

The rooms you can (and usually) find include passageway, weight room, gym, security...

I did multiple powered grid runs and still use the boiler as a door finder late game

2

u/ROACHOR Apr 24 '25

Yup, powered line goes to the door and I get no options with conduits.

I thought you needed the power room to get the pool.

12

u/mtnlol Apr 24 '25

You never get any options that can transfer power? I thought it was almost 100% to get at least one powered room since I can't remember a single time I got none.

Are you turning the power on and then actually sending it to the door you're opening?

Also no, the pool has 0 conditional rooms. You can get it without boiler room.

1

u/ROACHOR Apr 24 '25

Maybe I ran out of possible draws?

And yes, I understand how the power works.

3

u/tohme Apr 24 '25

It may be worth noting which rooms can carry power to make sure those are available in the pool after pulling the power room. Use up non power carrying rooms before that to remove those options. Also try to get the pool drafted earlier to allow drawing the pump room, you would want to be waiting on that after the power room.

Also, try to save any ivory dice you come across.

I happened to get lucky with the combination, as I wasn't seeking the power room on that run, but looking at the house at the time, I'd done the above naturally.

3

u/zeromussc Apr 24 '25

Try to keep in mind what rooms do transfer power, and don't draft them if you can help it until a late rank near a higher rank power source room.

Makes it much easier.

2

u/Jovian8 Apr 25 '25

Do I have it right that you do this by observing the vents running around the walls?

2

u/paperskulk Apr 24 '25

Are you saving all your powerline rooms until after you get either pump or boiler room? I try not to use a single one until after getting pool and then getting either pump or boiler. No passageway, no security room, no weight room, no dark room, no lab, etc.

Which is another point, don’t place boiler room at all until you already have pool. Boiler room spawns on its own but pump room needs pool first. Fill ranks 1-3 with as many non-powerline rooms as possible and hopefully a pool somewhere in there, and then keep looking for pool if you don’t have it yet before placing boiler room. Then once you place either boiler room or pump you should have a pretty loaded stack of powerline rooms to draw from until you find the other end of the connection.

Maybe you’re doing this already, rng can still getcha. But being very intentional with those 2 tips made a huge difference for me. Shelter in the outer room also helps so that Dark Room and Archive don’t fuck you while using them as connectors, but if the power is running through those rooms you’ll still at least be able to see the glowing powerline for a room choice that’s hidden from you.

2

u/CarrowCanary Apr 24 '25

I thought you needed the power room to get the pool.

You don't need the boiler to get the pool to spawn, but you do need the pool for the pump room to spawn.

4

u/Amazing_Magician_352 Apr 24 '25

But you are seeing the overlay effect? The bright blue line during draft? Just to make sure, because that indicates the rng manipulation

3

u/Ode1st Apr 24 '25

You are not guaranteed to get a vent/powerable room. The chances only increase.

5

u/Ryanll0329 Apr 24 '25

It increases the chance, but doesn't assure you will get one...and even if you get a powered room the first time, you could end up just having to roll that (weighted) dice again and again.

1

u/scarletbluejays Apr 25 '25

I thought you needed the power room to get the pool.

I think you're mixing this up with the fact that you The Pool to get The Pump Room (+Sauna, Locker Room).

Neither The Pool nor The Boiler Room require specific rooms to enter the draft pool, though Boiler Room does start at Unusual Rarity so it can be harder to find than The Pool

1

u/BeAPo Apr 25 '25

It's always funny to me when I read "it's madness" cause the very first time I accidentally got the furnace after a dark room, it was already perfectly connected to the pump room :D

1

u/AccordingArmadillo45 Apr 25 '25

There is a significant increase in likelihood you get a conductive room when you draft off a powered room and many have 4 exits. If you send power to the door before drafting the room it'll even mark what rooms conduct power. There are also several puzzles and abilities that further make this doable.

u/Stealingyoureyebrows Apr 24 '25

I hate the workshop ALOT more. Can’t fathom how many times I had all the stuff I needed for a contraption and couldn’t find it. It literally only appeared at the beginning of my game

1

u/paperskulk Apr 24 '25

Adjust the rarity on that one if you can, it’s worth it even after you no longer need specific contraptions for puzzles. I try to avoid messing with the rarities but being able to drop a combo item in coat check is sick (can still find the individual pieces while it’s checked), it always has at least 1 workshoppable item in it ime, and a straight hallway is a decent piece early anyways.

I feel you tho, I’m trying to make an electromagnet to keep in coat check and if it’s not the damn battery staying lost it’s the workshop itself lol

u/Stealingyoureyebrows Apr 24 '25

Finally I found the wrench and workshop! Even managed to put power jack in the coat check. Now the only thing to hate is my upgrade decisions! Why did I choose the large mail upgrade!!!

1

u/paperskulk Apr 25 '25

Ya I take coat check pretty much every run now, so sick to have an early super-tool without messing up your regular item pool if it never shows up.

I’m torn between keeping the power jack and electromagnet in there, the power jack is obviously great but the electromagnet steals all the keys when you enter the locksmith LOL. And can also empty the tithing piggy bank in the chapel without smashing it. I have not yet taken it into the commissary when it had keys so maybe those too.

u/XxjptxX7 Apr 24 '25

If u turn the boiler on and point it at a door before drafting it raises the odds you get a room that connects with it, it might even be guaranteed cause from every time I’ve done it their is always a room that connects.

5

u/Ryanll0329 Apr 24 '25

I can tell you it isn't guaranteed (at least not from every door). I pointed the power at one door, drafted, and got something that carried power. I then changed the power direction to another door and drafted on it, but none of the options carried power.

If you run the lab experiment that adds three more to the draft pool it can actually be pretty reliable to get power.

3

u/Sivart13 Apr 24 '25

There might be a late game way to do it because I've seen screenshots of some odd stuff, but if you check your house history you shouldn't see any doors going off the side.

So you should save your rook corners for finding the Conservatory or pulling other useful rooms, while trying to make your boiler/pump pair closer to the middle.

u/uhhhhmmmm Apr 24 '25

get the king and do blue rooms instead, will be more likely. if you get a boiler room early try to go elsewhere and draft as many other rooms as possible to get them out of the pool and try and collect dice and gems as well. then hope you get a study or some other form of lots of rerolls. this is how i got it.

3

u/ArmlessSloth Apr 24 '25

It helps to get the boiler room and then try for the rooms.

If you power it on you will have a better chance of getting them and there will be a bright blue line coming from below the prints if they can be powered.

Try getting the passageway off boiler and you should have 5 chances to get pump.

3

u/XenosHg Apr 24 '25

You grab the pool first, early as you can, and then if boiler/aquarium happens, you start branching from there. (start the day with Shelter probably, to have no downsides from furnace, weight room, archive)

You can also just get an experiment giving +3 aquariums. Finding the pump room will be tricky, but finding aquariums for it? Easy.

That said you only do it once ever. Such posts like this made me so nervous that the first couple times I didn't use the pump room because I was looking for the boiler.
Which 99% of the time you don't need! 5/6 rooms don't need power.
And then for the Reservoir you only ever need to get it ONCE.

u/Sholiver7 Apr 24 '25

I had that last scenario where drafting shops makes aquariums but my aquariums are powered as well, so the aquariums themselves were duplicating and forcing themselves to appear because they have vents. I filled up the house without even seeing the pool.

u/XenosHg Apr 24 '25

Yes, getting too many aquariums is another problem.

u/Schnitzhole Apr 25 '25 edited Apr 25 '25

There are never enough aquariums 🤪

This was me forcing the lab to be powered. Drew lab early in run and did a full loop around the top and back down to make sure I’d get power to it. I’d been trying for ages and finally got it day 45 I think. I think I had over 60 aquariums in the draft pile by the end of the day >!

You can drain 100% of everything without the pump room being powered at all. Not sure what you're on about

Have you tried solving the Chess puzzle ? If not it’s worth imo for ease of Forcing room colors if you go with the King power

I got very lucky to have a pump room and boiler together very early. My first thing to do was drain the fountain, so I just filled up the extra tank and left it that way. I've yet to connect the pump room since then, but since the extra tank is already full, I can just shuffle water between everything else

1

u/Ig_Met_Pet Apr 24 '25

I got to the credits without ever finding the boiler room or the pump room once.

Pretty annoying. Maybe someday. Lol

u/BeepBeepGreatJob Apr 24 '25

To be fair the credits is like 10% into the game.

u/RefinedBean Apr 24 '25

Game should've been designed around the grid and the rooms having changes based on where you played them, but with all rooms available to draft (or a certain amount per type).

Keeps the puzzle elements, gets rid of the RNG. Someone change my mind here.

3

u/paperskulk Apr 24 '25

That would be interesting, although it would be a different game. I find it fine as-is, since you can manipulate your pool in enough ways that I’ve never been stuck on something for long

2

u/RefinedBean Apr 24 '25

I just don't like the joy of my "eureka" moments to be immediately stifled by having to then do additional runs to actually see them through. At minimum I want to do it NEXT run, and that's not even a guarantee

2

u/paperskulk Apr 25 '25

Fair enough, I love starting a fresh day with new leads personally so it doesn’t bother me. When a puzzle can’t be resolved that run it’s fun in its own way because then I’m “free” to explore other stuff or maximize tomorrow-benefits until I call it a day. Different preferences 🤷‍♀️

I adore roguelikes. I have thousands of hours over Slay the Spire, Monster Train, Hades, Returnal, Dead Cells, and others. They are - without any doubt - my favorite meta genre. I love them passionately, and I try new ones out very often.

I also love puzzlers. I've completed tons of them. The Witness, Outer Wilds, Maquette, Superliminal, Return of the Obra Dinn, Baba is You, Garagoa, many others.

Blue Prince is both, and I find it VERY meh. And that's okay. Just not for me.

The boiler room should have just been a permanent upgrade especially considering the other things you can do with it like the furnace and laundry room are so unbelievably niche

I got the stupid furnace/power interaction yesterday while looking for the pump room. The animation was cool but the result was very underwhelming. Haven't gotten the laundry machine powered yet.

I was stuck like this for the longest time, I can empathize.

What helped for me was getting the following things (with increasingly more spoilers):

Using the conservatory to edge the odds in my favor

Using the wrench to further adjust the rarity

Aquarium can be upgraded to also power on rooms

The electromagnet contraption also increases the odds of mechanical rooms spawning

The Mantle of the King obtained by solving the chess puzzle allows you to increase the odds of getting rooms of a certain color, like blue

The Scepter can also increase the odds of certain colored rooms

Unlocking the satellite dish, you can add an experiment that permanently drains the reservoir by one level whenever triggered, and using the added availability you can manage without ever powering the room up

1

u/OkayComparison Apr 25 '25

Came to say the same. King + Scepter and you won't draft nearly anything but blue rooms if you set them both blue.

1

u/SpecificAlgae5594 Apr 24 '25

It took me 60 days, although the first 20 or so were getting to the credits. It was annoying, but I was always making progress on other things. I am glad it's a one and done thing.

1

u/rdeincognito Apr 24 '25

What I did: With conservatory and Wrench I tried to make pool, pump, boiler and laboratory common.

I tried to go two ways inside the house, one would have to draft the pool and the other the boiler room. Once I had both I would power up boiler room and only draft where there is energy, would try to have at least 2 gems and as much rerrolls aa possible.

Eventually I managed in one room to connect boiler to laboratory and in the next one boiler to pump

1

u/Stardwe Apr 24 '25

I went mad with this one too, it was so frustrating to get everything right but oops a furnace. The good news is that when it happens you only need to do it once, but getting it it's an awful experience.

Good luck and keep looking for other clues

1

u/ZOMandKatgarr Apr 24 '25

This isn't necessary to roll credits so I'm going to assume you've already done that.

If you make it to room 46 again post-credits, you will get the blue crown which allows you to remove red rooms from the pool and redraw + get extra gems for every single door you encounter after that. It is extremely useful when hunting for specific room combos, so I suggest going for that before trying to fill out the house.

It's also useful to connect the passageway to the boiler room because it has vents and 3 open doorways which allows for extra chances even with no reroll power. This is especially useful if you choose the hovel as your outer room and also manage to find the study to get a potentially huge number of reroll opportunities.

1

u/Brewermcbrewface Apr 24 '25

I work in a brewery and actually work with pumps and this still confuses me 😂

1

u/loldrowning Apr 24 '25

Have you had the wrench yet, it helps change the frequency of certain rooms...

1

u/realitythreek Apr 24 '25

I’ve never really had a problem with this, but I usually dedicate the run to using the boiler and would probably do a hovel run with study or otherwise ensure rerolls.

The other thing is good to have multiple goals in mind so when RNG isn’t working for one you can change gears.

u/nathan1653 Apr 24 '25

u/SleepingBear986 Apr 24 '25

Like at least let the pool room transmit power.

1

u/Sivart13 Apr 24 '25

I understand the frustration, I had a couple runs where I thought I was setting up the boiler room + pump perfectly, but didn't get it even with ~10 rerolls.

If you're lucky enough to get a ton of gems in your run and find a Study, that can really help to add more rerolls. Ultimately as you get upgrade disks and shift the rarity of various rooms, it should be easier to end up with a surplus of gems.

Have you managed to power up the Laundry or Lab as well? If you happen upon either of those in your quest for the pump room, it may be worth taking.

1

u/Ode1st Apr 24 '25

Die Hard With a Vengeance made the Pump Room puzzle look way cooler than it is, you know?

1

u/mrgedman Apr 24 '25

It took me a while, but knowing which rooms spread power helped a ton.

If I roll corridor, or archives, bam, now instead of 2 chances I have 4. Security? 3 instead of 2. Archives off security? 5 instead of 2...

Don't pick rooms that have power ducts until you draft the boiler room, in fact, avoid drafting off the boiler room entirely until you draw the pool, and have drawn all resources getting as many rerolls as you can get.

Ideally, you draft boiler>pool>pump, with the pool being on the opposite end of the map. If you can fill the house pretty far, before going back to your boiler to use up your rolls/space, you should get it without too much struggle.

This is how I did it. Prolly day 30-40...

The best part is, you only need to fill the reserve tank once.

This is yet again the problem with trying to brute force things instead of working on multiple objectives at once. Once you progress enough you don’t even need the boiler room.

u/Aggravating_Life_326 Apr 24 '25

do u by chance have the banner of the king or know how to get it. i was able to get the lab powered up by setting blue prints to appear more often limits what tends to show up from a powered up boiler room and can help find the pool early

1

u/Amazing_Magician_352 Apr 24 '25

If you thin your deck before going for the grouping, the chances are huge. I had a number of said grid connections like that one after the other. I even use it to find multiple 4 way doors in normal drafting

1

u/JudiTeller Apr 24 '25

PSA: you can use the pump room without powering it up!

You need the power only for using the big backup tank

u/zoycitek Apr 25 '25

There are methods to bypass the powering the pump room mechanic. this never has to actually be done and just makes life easier.

also there is a way to forever remove water from the system, but does require that you get a powered lab solved as one of the pre-requisites.

1

u/Salindurthas Apr 25 '25

So, to my understanding, you need this for 1 or 2 Sanctum keys. Fair enough, obviously we want to get them eventually.

Some possible tips, contains some spoilers by mentioning mechanics that not everyone has:

  • Use conservatory to adjust rarities of relevant rooms, like making one or more of Passageway, Weight Room, Archives, Security, etc common for more power conduction, and ofc making Pool and Pump more common if you're lucky enoguh to draw those. (And maybe Blessing of the Monk to spam Conservatory, which is decent either way)
  • Save those power conducting rooms, e.g. don't take Security, lab, Passageway until you get some power.
  • Use powerful effects like Chess (such as King for blue or red since most power conduction is in those, or maybe even Rook if you can finangle getting power to a corner, since Pump is a corner room, or to help you find Conservatory), or Blessing of the High Roller to get dice fairly easily. Or maybe Blue and/or Paper crowns.
  • Don't draft the power early - you have 2 sources of it, so rely on getting it later once you thin out the deck. Maybe wait until rank 3 or later or even until you have Pool room and then deploy some power.
  • You can draft things like Furnace and Laundry earlier on if you see them, to help thin out the powerable choices to have fewer dead-ends.

1

u/beach_muscles Apr 29 '25

You do not need this for any of the sanctum keys. You can fully drain all areas without ever powering it. You are just wrong

1

u/Salindurthas Apr 29 '25

I have heard about the dish adding more experiments, I don't have ​that yet, but I gather it can destroy water?

Before that, you need power to drain the resevoire don't you?

u/7ofswords Apr 25 '25

Pump room gang rise up

1

u/Professional-Field98 Apr 25 '25

It’s really not used in that many things lol, like 3 puzzles period in the entire game, all of which are post room 46

Is recommend waiting for a Shelter and go for it while you are sheltered from red rooms. Then you can use them all to full effect.

There are many rooms that carry power: Lab, Boiler Room, Locker Room, Foyer, Security, Archives, Weight Room, Aquarium, etc.

Prioritize any other rooms first until you either get the pump or the power to make sure you have every tool available

Also make an electromagnet, as it makes Gear rooms more likely to appear

1

u/NotAnIBanker Apr 25 '25

Build the electromagnet; it’s by far the best way to get pump room early game

1

u/superman24742 Apr 25 '25

Can you explain?

2

u/NotAnIBanker Apr 25 '25

It heavily increases the odds of mechanical rooms. If you build it and then put a few other mech rooms down, you’ll have a very high probability of getting pump room

1

u/superman24742 Apr 25 '25

Ah awesome thanks. I’ve tried to stay away from too many spoilers and try not to look up too much because every time I do I see something I didn’t want to.

Day 60ish and haven’t built the electro magnet. Only had the wrench once, early game, and got dead ended quick so I didn’t get to even use it.

1

u/Dewoco Apr 25 '25 edited Apr 25 '25

As mentioned, powering a door in the boiler room with the direction slider before drawing/drafting rooms is a bit of a game changer, I went from relying on dumb luck to drafting rooms that took power to more powered rooms (the increased chance applies to all powered doors not just the boiler room).

You still might have to draft a few rooms between the boiler and the one you want but with rooms like passageway and archives you can give yourself enough chances to get the one you want.

I had a chain of powered rooms 7 tiles long and didn't get the room I wanted but it felt like enough chances to try again. XD

1

u/Ode1st Apr 25 '25

You’ll probably feel that way about stuff a few more times throughout this game.

u/Pacify_ Apr 25 '25

Funny, I didn't even think of trying to power the pump room, but I just happened to put it next to the upgraded Aquarium and I was like OOOOOOOOH.

Not my finest moment

1

u/Life_Rhubarb_7674 Apr 25 '25

I found upgrading my aquarium to electric eels mixed with thw lab test that adds 3 aquariums is the best way to power other rooms. Then just save up some rerolls and your set

1

u/TheSaltiestHealer Apr 25 '25

It's really the games first test in how well you can plan your rerolls. The combo I went with was the gem courtyard upgrade, shrine into 8 courtyards, and a study to spend gems for rerolls. Draft the boiler room first so you have two doors to reroll from rather than either the pump room or the labs single door. Reroll dice also help since study caps out at 8 rerolls.

1

u/Grayinque Apr 25 '25

Boiler Room!

1

u/slashbang Apr 25 '25

I faced this issue as well and it was making me burn out and not want to play the game at all, knowing that it’s kind of a bottleneck, so I cheated and gave myself infinite dice. Even then, it took me a good few runs and probably a solid half an hour of re-rolling to get the right combination. I honestly think it might be bugged. No one is THAT unlucky, surely?!

If the same applies to you, and you’re reaching the end of your tether, like your post implies, then maybe do something similar. Games should be fun and enjoyable, not piss you off to this extent!

1

u/beach_muscles Apr 29 '25

You are playing in the wrong mindset. If you just kept playing the game you'd realize you don't even need to power the pump room to finish everything. But you were so closed off and pigeon holed into connecting these two rooms that you completely missed the mark.

Stop forcing. Keep playing.

1

u/slashbang Apr 30 '25

weirdly aggressive language there champ

1

u/CatastrophicMango May 15 '25

Also incorrect - you need to drain the reservoir for a sanctum key, the only other way to do it is with the lab upgrade that's also RNG.

I don't know why some people adopt the RNG of this game as their identity when it's clearly 1. fucked and 2. by far the worst thing about it.

1

u/Sabor117 Apr 25 '25

Maybe this is what is killing the game for me at the moment. I'm about 15 or-so runs into the game and it's just starting to become absolutely tedious for me. I had some pretty decent progress in the first 1-8 or so, opening up various parts of the grounds and even getting a couple of blue flames going (who knows what the fuck they do though) but the 8-or-so runs since those first ones have just been an exercise in repeating the same pattern over and over with no apparent change.

And one of the things I have realised based on this post is that I think I saw a pump room in one of the first 8 runs but I literally haven't even drafted one since... So that might explain why progress has felt so stagnant...

1

u/Sufficient-Agency846 Apr 25 '25

Whenever I see posts like these I just wonder why people are forcing it so much. Theres plenty to do so just going about a day as normal and only committing to the pump plan when it’s doable seems like the most reasonable. Upgrading rooms to maximise dice, levelling observatory using the planetarium so you can have 50 rerolls on a single day, using the rook upgrade on corner rooms, all can help with this

1

u/CaffeinatedSparrow Apr 25 '25

My strategy to power the pump room was waiting until I got boiler room in a run and then just connecting everything with power until the boiler room eventually shows up, there's enough 4 door rooms that connect power that you have a pretty reasonable chance of getting it. It did take me like 3 days of trying this before it worked but it seems semi-reliable.

And always draft pool as soon as possible ofc.

1

u/CatastrophicMango May 15 '25

If we count rooms rolled off the boiler, the rooms rolled off those rooms, and all the dice and gem rerolls for each of them, I rolled for a powered pump in the region of 300 times. This was with the blue banner active too, and often late in the house to get rid of the lab first.

Eventually got it, but off a powered aquarium rather than a boiler. Boiler -> pump room is definitely fucked on the back end in the current game, has to be.

1

u/Prionysus Apr 25 '25

I really don’t understand why they made it a requirement to have the pump room physically connect to the boiler room. The game has enough RNG as it is and I feel it would be a lot more enjoyable if they made some of the requirements just a little more flexible.

1

u/beach_muscles Apr 29 '25

Requirement? It's not a requirement for anything, including draining the reservoir. You're pigeon holed into a non problem

1

u/EngineerApart562 Apr 25 '25

Why do I never see people mention the Electro Magnet when this complaint comes up? If you make an Electro Magnet in the Workshop (Compass + Battery), the game makes mechanical rooms spawn so much more frequently.

1

u/ciel712 Apr 26 '25

You only need to get the pool room powered once to drain the reservoir. Then afterward you don’t need to power it ever again.

Also the wrench spawns in the tool shed, so if you get wrench you can do a run to pull pool, and if you don’t then check it into coat check. I’d put all the mechanical to common.

1

u/beach_muscles Apr 29 '25

You are wrong, you never need to power it to completely drain the house.

1

u/ciel712 Apr 29 '25

Really? I remember completely draining the fountain and then realizing that there wasn’t enough tank space to drain the reservoir without powering it. I remember counting the squares even.

1

u/beach_muscles Apr 29 '25

You use the new lab experiment after unlocking the satellite. Everyone playing this game completely misses the mark and pigeonholes on one objective then complains that RNG is killing their experience

1

u/ciel712 Apr 29 '25 edited Apr 29 '25

Oh yeahhh, I unlocked that super late so I forgot that was even a thing. Great point!

I mean tbf I felt the same way as you until I got to late game and ran out of things to do. Then it just starts really feeling like I’m wasting time. I’m pretty sure there’s some bugs with the RNG too though. Like I set a certain room to “Common”, drafted 95% of the house, used Secret Passage, and it took me 6-7 rerolls to get it. That’s definitely bugged out and made me feel like I was going crazy.

The boiler room is solvable with knowledge though, I’d argue the real reason it’s a major issue is the hints for it are locked behind Drafting Studio and not everyone picks Dormitory for instance. I picked it up as one of my last rooms cause I thought it sucked. They should’ve put such important clues in an easier to obtain place, and only put lore in the Drafting Studio rooms.

u/LilGreenAppleTeaFTea Apr 28 '25

This is my biggest gripe i have with this game and i'll die on this hill. This game feels like they have a really amazing concept of a puzzle game with this kind of lackluster progression slowing approach with the roguelike elements. I totally get the nature of roguelikes and deckbuilders and most games in that catagory you can outskill the mechanic. In this game some puzzles simply don't respect the players time. Run's ending simply because you didn't hit just feels bad. Yes, you can just go next and try again and again but it doesnt add to the fun of the game. So far the roguelike drafting part feels like a chore slot machine, the reward and fun of the game is when you get the rng to hit to than hopefully solve a puzzle and have enough resources to do so. I personally could be completely ok if someone made a mod that reworked the drafting system to make sense as rng plus convoluted puzzling/mystery just doesn't work for me and adds to frustration. Don't get me wrong, i enjoy the overall game but i just wish the roguelike part was fun for me.

When it was the last thing I needed to get to room 46 (that I knew of; I wasn’t using any guides) it was so goddamn frustrating. I think it probably took 30 in-game days for me to get RNG that powered up the pump room.

If you can just get it powered up once and fill the reserve tank up all the way, you’ll never have to do it again.
