By Rayark Inc. - download for iPhone and iPad

Cytus is a rhythm-action title in which you have to tap and drag circles in time with the music (pop, jazz, trance, and drum 'n' bass).

A line that constantly moves up and down the screen also helps you out if you're a little, say, rhythmically challenged.

The game contains 28 songs and nine difficulty settings, as well as Game Center-enabled leaderboards.

Dragster Mayhem
By Euan Potter & Evan Lancaster - download for iPhone and iPad

Yes, Dragster Mayhem does just involve you driving in a straight line at almost the speed of light. But, really, is that so bad?

There are enough upgrades, tracks, and opponents to keep you occupied for the weekend.

Oh, and for those of you who like competing against your friends (who doesn't?), good news: there's a Game Center leaderboard. Result.
