Spit (aka Speed)
iOS Universal Games
Spit, also known as Speed, is a two-player card game in which the aim is to get rid of your cards as fast as possible. Players do not take turns - physical speed and alertness are required to play faster than your opponent.
You can play against a variety of computer opponents, or if you like, against one of your friends -- on the same iPhone / iPod Touch!!
Bugs have been fixed for newer iOS versions.
