99

"99" or "Ninety-Nine" is a simple card game that you play against three people (in this case they will be computer opponents).  As you play cards, you add their value to a running numeric total, and the object is to avoid playing cards that cross certain numeric boundaries (such as 33 to 34, 66 to 67, etc.).  When this occurs, you lose a point.  The winner, obviously, is the player with the most points at the end of the game.  Friendly interface, several options available, sound effects, and win/lose tracking.
