Sliding Tile Puzzle Screensaver
The Sliding Tile Puzzle screensaver shows the classic 15-puzzle solving itself over and over, shuffling and then calmly re-solving. It is free, runs in your browser, and ESC exits.
How the Sliding Tile Puzzle screensaver works
The saver starts with a solved grid, then performs a random shuffle of valid sliding moves.
A simple solving algorithm then slides tiles back into order, one legal move at a time.
Once solved, the cycle pauses briefly before shuffling again.
Every move follows the real sliding-puzzle rules — only the tile next to the empty space can move.
A worked example
The grid shuffles into a scrambled state, then tile by tile it methodically slides back into perfect numerical order.
