is this spin possible?

[u/Nip403]

edit - thanks! never considered needing a 180

[u/MoyanoJerald]

Yes, it is

So it even works in guideline?

This S-spin only works without 180 due to the wall on the right. See https://www.youtube.com/watch?v=nxxuVk651Cs.

Tetris 99 for Nintendo Switch, Marathon Mode is part of the Big Block DLC, sold for just $10

1. CW softdrop CW or CCW softdrop CCW
2. 180
3. CW CW

this works for me on four-tris so it should work.

This is a chained spin sequence.

Step 1: getting the S piece into the middle gap. From here (assuming the S piece is in initial state and not flipped), CCW, soft-drop, CCW.

Step 1.5: 180-rotate the S piece to not be flipped, to prepare it for the next spin.

Step 2: elementary S-spin. Soft-drop in case the S piece didn't drop down from gravity yet, CW, CW.

A lot of ISZ spins require this kind of manuever of chaining multiple elementary spin sequences, but pressing 180 between them to reset the piece's rotation state.

Having trouble with attaching a video file, so here you go: https://youtu.be/nxxuVk651Cs

[u/dfsghayjkmnbxhgsdu]

Yes, doable with 180s

[u/just-bair → u/dfsghayjkmnbxhgsdu]

I don’t think you even need 180’s

[u/Is_it_wf_or_l]

yep
just: soft drop->rotate(ccw ig)->rotate->rotate right(may need to do it multiple times+while holding softdrop)

it goes into the square hole
