If you're familiar with the game, then you already know how it works. You start with two tiles, one on each side of the table. The object of the game is to take the two tiles and flip them over one another to create a domino stack of the same sign. You can only do this if the two tiles are of the same rank.

What makes the game interesting is that you don't need to play against a computer. You can play against other players online. You can also play with one player offline. You can even challenge players worldwide and see who is the best.
