Canabalt is a simple but addictive game for the iPhone. The aim is to escape by running across randomly generated city rooftops. All you can do is jump by touching the screen. Sounds simple, and it is to play, but it’s got that ‘just one more go’ appeal that’s hard to resist.

The graphics are stylish and fast and the music is awesome. As the game suggests, play with headphones. If you want to try before you buy there is no lite version but you can play the flash game online. So can anyone beat my high score?
