I've been trying out lots of differert Palm g ames on my 7135. So far here are my top 5 games that I would highly recommend:

GALAG - Excellent translation of the old video game Galaga. A step above most Palm action games!

VEXED - a totally addictive puzzle game. Colorful, challenging, and despite the title, I find it oddly contemplative and relaxing. Its a game you can play discretely and quietly in any situation without looking like a juvenile.

SPACE TRADER - probably the highest rated game on the Palm right now.

MONOPOLY - kind of tiny, but an excellent port with all the gameplay of the board game.

CHESS GENIUS - the full screen mode looks great on the 7135.

I could make 5 more recommendations, but these are the games I play the most. These games are either completely free or if they're demo's, the demos are quite satisfying and repeat playable. You can find them all at download.com.com.
