Pigs
This dice game has a humorous aspect that will become obvious when you start playing. You compete against a computer-generated player with the goal to try to reach the highest score, which by the way is not that impossible. Although if you are too much of a dare-devil you will probably loose at the end of the 14 rounds.
Yambo
This is a 1-player dice game based on the old and not so familiar Yamb game. The game has decent graphics (although no animation) and pretty neat sound effects. You need to have knowledge of the official rules of Yamb since the game has no help file.
