Name some! Go!
I liked Words with Friends when I had an iPod touch. I'm looking for something like it (Scrabble), but also anything else that's fun and you can play with your friends (poker, shooting, conquering, puzzles, etc). Preferably something where they can make a move, I receive a notification, and respond back at my convenience and vice versa, not where we both have to "be online at the same time". Oh, and free, please.
