Dominoes

Description
Dominoes is a single-player-versus-computer board game for multiple systems.
Each player starts with seven dominoes, and takes turns placing a piece with a numerical match to the domino on either end of the puzzle. If the player can't go they must knock, and the other player gets a chance to play. In Domino Out, when no moves remain, the player with the lowest score receives points equal to the difference between the two players' hands. In Fives and Threes, players also receives points each turn equal to the total number displayed divided by 5 or 3. If the number is not divisible by either then no points are awarded.
