Your goal

Arrange the numbered tiles in ascending order, row by row from the top left. Each move rotates a square block of tiles about its centre: 2×2 by default, larger on harder settings. With oriented tiles, every triangle must also point up.

How to play

Tap the point where four tiles meet to rotate that block anticlockwise. Turn on Mark mode to rotate clockwise. For odd block sizes, tap the middle tile. Keyboard: arrows move the outline, Enter rotates anticlockwise and Space clockwise.

Tips

Solve the top row first, then the next, and leave the last two rows for the end.
Two turns of the same block swap tiles diagonally, which helps with the last stubborn pair.
Type offers a short shuffle. Undo exactly that many moves for a gentle start.

Use the board’s Type menu to choose a size or difficulty. Undo and Redo let you explore. Solve reveals the answer when you choose it.
