If asked what the current best-selling iPhone game comprised, probably the last thing we'd respond with would be "a tale of avian revenge of Hitchcock proportions".

But Angry Birds (£0.59 from the App Store) is just that: 105 varyingly frustrating levels in which your goal is to obliterate an endless landscape of Shrek-like egg thieves using only a catapult and an arsenal of beaked assassins. Bizarre as it sounds, it's one of the most addictive handheld titles since Tetris. Also available on selected Nokia handsets via the Ovi store.
