Guitar Hero has got to be one of my all-time favorite PlayStation games. Now, Tap Tap Revenge brings the same principle to your iPhone, allowing you to be a music legend wherever you go.

After starting up Tap Tap Revenge you need to choose a piece of music and a difficulty setting. A series of glowing balls, representing beats, will fall in time with the music along three fluorescent lines. Once these balls reach the baseline you need to tap the screen or shake your iPhone. Only if you do this at exactly the right moment will you take the points. Make a mistake and you'll be docked points.

You can also choose to play Tap Tap Revenge in two-player mode. In this variant, there are two sets of balls that head towards both ends of the screen. Each player must tap his own baseline at the right time in order to get points.

The graphics in Tap Tap Revenge are great, but the playability is even better. The game is very addictive and even if you get bored of the default songs you can download new ones. Once you've achieved all you can in this one, why not check out the latest version of the game, Tap Tap Revenge 2?

If you're a fan of Guitar Hero, you'll love this pocket-sized version for iPhone.
