6. Tap The Frog 2
Most games on iPhone are simple, quick-to-play minigames that are designed to fill dead time in your day, whether you are on the bus to work or sat in the doctor's waiting room. And most of them are, frankly, rubbish and not worth 69p of your hard-earned cash.
Tap The Frog 2 is a rare exception to this rule. A collection of perfectly designed mini-games, which require you to rapidly tap frogs in countless permutations.
