A seemingly simple puzzle - eleven dominos, a four by three grid with one blank. Slide the one from the top left corner to the bottom right corner. But the catch is that at no time can you have any domino touching another domino with the same number (the exact opposite of traditional domino games).

The result - a challenging, frustrating, mind bending puzzle, easy to pick up, difficult to master. If you're really good, you can solve it in the minimal number of moves, but often you'll feel lucky to solve it at all...
