10 Pin Shuffle is great
This is my new favorite iDevice game. It really is two games in one: a traditional shuffleboard game, and a second mode that combines shuffleboard with bowling. Both modes offer several variations, including competition against several CPU opponents. The realism of the bowling pin action is astoundingly good, and the skill and fun factors are high. I've purchased a couple other shuffleboard games, but this one is in a league of its own.
