Sliding Puzzle
Sort the numbers moving them the board.
Rules
The objective is to sort the numbers in ascending order (1, 2, 3, and so on). Numbers can move orthogonally (vertically or horizontally) if there is an empty space in that direction.
Click in a number, and if there is an empty space orthogonally, it will move to that space. Click the Start button to start a new game. You can also select the size of the board to increase the difficulty of the puzzle.
