Glossary Entry: 15 Puzzle

Quick Definition

This is a common type of logic puzzle.

To make this sort of puzzle, an image will be split up into a 4 x 4 grid of tiles. One of the corner tiles is then removed, leaving 15 tiles (hence the name, 15 Puzzle).

Gameplay is simple: To start, the tiles are randomly shuffled. Then, the player slides the tiles around using the gap in an attempt to return them to their original position. The puzzle is solved when all 15 tiles have been returned to their place.


Click on the button marked "Scramble" to begin the game. Pieces can be moved by clicking on them when they are next to the hole.

Pieces that are not in the correct place, then they are shown with a thin border.
