About the game
Slide the numbered glass tiles into the empty space until they are in order from left to right and top to bottom. Leave the empty space in the lower-right corner. Every shuffle is solvable.
Tap a tile next to the empty space, or swipe it into the gap. With a keyboard, use Tab and Enter, or the arrow keys to slide in that direction. Undo takes back your last move; Hint highlights a tile that leads back toward the solution. Hints follow a valid route and do not promise the shortest route.
Choose columns and rows independently from 2 to 5, a calm or deep shuffle and glass, brushed aluminium, slate or walnut tiles. Every slide and undo counts as a move; hints and undos also count as assists. There is no time limit. Your current round resumes locally on this device.
