Fifteen Puzzle

Fifteen Puzzle is a free sliding puzzle game where you try to put the tiles back into their proper order by moving tiles into the empty space. While the classic game uses a 4x4 grid, Fifteen Puzzle also lets you play with 3x3, 5x5, 6x6, and 7x7 grids. You may either use the stock images provided by Fifteen Puzzle or you can use your own image.

If you want to make the game more difficult, try turning off tile numbers and increasing the grid size.
