About this game

One square is empty, and that emptiness is the only tool you have. Tap a tile beside it and the tile slides over. Everything else waits.

The target is not a picture but a rule: each row wants one kind of tile. Tiles read by shape and by the number of rings nested inside them, so nothing here depends on telling two colours apart.

Every board is scrambled by sliding backwards from a finished one, so it is always solvable. The parity trap that makes some sliding puzzles impossible cannot occur. The "best" count is the true minimum, proved by search rather than assumed from the scramble.

No timer and no fail state. A small key under the board shows what finished looks like.
Classic slide puzzle. One empty square, tap a neighbour, sort every row.

What’s new

The level map's stops no longer sit on top of each other, so the road shows between them and the numbers are easier to read.
