How do you play Twiddle?

Twiddle gives you a grid of scrambled numbers. Tap any cell to rotate the 2x2 block anchored there 90 degrees clockwise; long-press or right-click to rotate counter-clockwise. Keep rotating until the numbers are in ascending order, lowest top-left to highest bottom-right.

Is every Twiddle scramble solvable?

Yes. For grids 3x3 and larger, every arrangement of the numbers is reachable because a 2x2 rotation is a 4-cycle (an odd permutation), so both even and odd permutations can be produced. The puzzles here are scrambled with legal moves, guaranteeing a solution.

Is Twiddle free to play?

Yes, Twiddle is 100% free to play in your browser with no download or signup. Progress is saved automatically on your device.
