meteor blitz for the non-existent load times and awesomeness. ORBITAL, i play this in line at stores so much. my top go to game for puap runners up that are great but don't get as much play: skee-ball, must.eat.birds, racer, doodle jump
Pick up and play I have to admit, I am a little biased but Tile Poker is a really great pick up and play puzzler. It loads fast, auto saves your game, and the nature of the play allows you to invest as much or as little time as you want.
Rocket Monkey (Currently running a $200 iTunes gift card contest) Pocket God And many more other great pick-up and play games
I personally like Puzzle Quest. That's usually my pick up and play game. Just turn it on, do one fight or more depending on how long you have/want, then just quit when you beat them, since it auto-saves. And it's really good too. I also use Zombieville in the same way. When I have time I turn it on, beat a level, and turn it off.
I personally like Doodle Jump, Swingaling, Tap Tap Revenge 3, Canabalt, and Champion Archer to name a few.
I'd like a game that doesn't need much concentration or too many fingers or accelerometer use. for some reason I only think of orbital. also maybe solitaire
I was waiting for someone to say that. Doodle Jump and Spikey would be my choice. Spikey is a game that should get more buzz than it does.
Doodle Jump. And believe it or not Rolando 2 isn't too shabby either. It loads rather fast, loved playing it real quick when I had some leisure time this week.
Spazzle! and Spazzle II! A little bit of self-promotion for Spazzle and Spazzle II... but to make it fair, I'll defer to a quote from one of our reviewers: "This game is definitely one of the best pick up and play, kid-friendly games the AppStore has to offer... You get a highly polished game that will surely keep you entertained while on the go." - The APPera Spazzle II saves your game state if you get a phone call or whatever... Other personal favorites: Aqua Globs, Fling, Peggle
