Mirrorwalk

Two blocks share one board. When you move the blue one, the pink one moves as its mirror image.

Get blue onto the blue ring and pink onto the pink ring at the same time. Walls stop one block but not the other, and that is the whole trick.

No ads, no sign-in. Earn up to three stars per level by matching the shortest solution.

How it was made: the code and this page text were written with the help of an AI assistant (Claude). Graphics are drawn in code, with no image, sound or font files. Levels come from a seeded generator and were kept only if a solver found a solution, then sorted by solution length.
