User Summary Puzzle game. Each level is a mosaic of pieces of different colours. The player can swap two pieces by clicking on their junction. If one of the pieces ends up adjacent to a piece of the same colour, they both disappear. The goal is to clear each level of pieces. The game has two modes, normal and tournament. In tournament mode how far you progress in the game depends on your score. If you score too low, you may even regress and end up in an earlier level.
