I think I've finally found it: the ultimate free app that offers simple gameplay combined with addictive mechanics. I'm talking about PapiJump and if you haven't gotten it already, download it from the App Store right this second!

Okay, so maybe I'm exaggerating a tad but that's not to say this app isn't crazy fun. The idea is simple enough. To play, all you have to do is keep the bouncy ball with a smily face from falling. As you jump from level to level, the platforms get fewer and far in between, making your attempts more difficult.

You control the smily face by tilting the iPhone to the left and to the right. It's really just as simple as it sounds. But simple is good, especially for on the go gaming when all you want to do is play for a few minutes here and there.

The object of the game is to get a high score. You can submit this score, as well. You can also view instructions on how to play, though doing so will take you out of the game and open the web browser.

PapiJump is easy and fun. And these days, that's precisely what I want out of a game.
