About
The pocket puzzle that predates phones, in three sizes: the quick 3x3 Eight, the classic 4x4 Fifteen and the brain-melting 5x5 Twenty-four. Shuffles are generated from legal moves, so every board is solvable. Tiles slide smoothly, rows are colour-coded and tiles already in their home square glow. Your lowest move count for each size is saved.
Objective: Restore the tiles to numerical order in as few moves as possible.
Modes: 4x4 Fifteen, 3x3 Eight, 5x5 Twenty-four
