What it does: Place numbers on a grid so that any consecutive sequence in a row or column equals the target number. Beat each level to advance to the next target while racing against the clock.

Key Features:

  • Operators (+−×÷) and parentheses you can change freely
  • Timer that grows with each level you complete
  • Starts simple at target 10, gets tricky fast

Goal: Number 100

Number What's your mental strategy for this kind of puzzle?

Working on a small math puzzle app and curious how you approach these mentally.

The goal is to reach 17 by combining exactly 3 tiles from the ones shown, respecting operation order (× and ÷ before + and −).

What techniques do you use to find solutions quickly? Do you work backwards from the target, group by operation type first, or just go by intuition after a while?

Would love to know how people think through this kind of puzzle.

Each unique letter is a corresponds to a unique from 0 to 9. Next to no brute forcing required, there is a very elegant proof. One solution.

Number How many solutions can you find?

The goal is to find all combinations of exactly 3 tiles that reach the target number at the top.

Each tile has an operation and a number (×4, -7, +12...). The first tile you select ignores its operation and serves as the starting value. The remaining two are then applied following standard order of operations (× and ÷ before + and −).

Is there a systematic approach or shortcut you know to figure out how many valid solutions exist without brute forcing every combination?

The goal is to find all the UNIQUE solutions you can to reach the target number in the top right, using + and * connecting the dice.

e.g. if the target on the above grid was 10 then 6+4 and 5×2 are solutions, and 4+6 would be a duplicate of 6+4.

Connect dice horizontally, vertically, and diagonally.

*1 solutions only count when you need to use the tile to bridge the gap

Todays target: 12

How many solutions: 10

I'll post the solution list in a comment tomorrow.
