What are some good and fun free apps for the itouch?

Beer Pong

I really like Labyrinth Lite. The controls are very nice and responsive, and the music is very soothing.

Sol Free —A solitaire game.
StoneLoops! of Jurassica Lite —Hard to describe.

Both are fun and free.

Tap Tap Revenge 2, iCopter, Flood-It!, and Hangman.
Okay, sorry but I need to go on a rant. There is no such thing as the iNano, iClassic, iShuffle, or iVideo. The same goes for the iPod Touch, it is not called the iTouch.

Lux Touch is an awesome Risk game. TrafficJam is a great puzzle game. Though not free,
Scrabble is worth ever penny!
