The object is simply to reveal the original picture by swapping tiles until they are all correctly placed.
To play: find two tiles you want to swap. Click on one. It will receive a red highlight. Click on the other and the two pieces will be swapped. Continue to swap tiles until you solve the puzzle.
The Reveal/Hide button can be turned on and off, and shows a blue "X" through tiles that are improperly placed. Tiles that are in their correct position will remain blank.
The Mix button resets the puzzle.
