How to Play
This sliding tile puzzle comes in three sizes: 3×3 with 8 numbered tiles, the classic 4×4 15 Puzzle, and 5×5 with 24 numbered tiles. The 3×3 game is also called the 8 Puzzle.
Slide numbered tiles into the empty space. Only a tile immediately above, below, left, or right of the empty space can move.
Arrange the numbers in ascending order, with the empty space in the lower-right corner:
123
456
78
With the board focused, arrow keys move the empty space in the arrow’s direction.
