Originally released in the arcade and on Xbox 360, Cave’s manic shooter is easily one of the most addictive games on the iPhone. This iPhone version is a great way to enter Bullet Hell for the first time. The touch screen controls are surprisingly fluid, letting you touch anywhere on the screen to control your Galuda ship The iPhone edition also features a unique ability, ‘Awakening Pulse’, which is basically a charge attack you can set off to maximise your score.Retro graphics, adorable character design and catchy music. Espgaluda II is a dream to play on the iPhone and well worth your £5.49/$8.99. Plus you get to hear cute Japanese girls make all sorts of odd noises, which always goes down well.

Square Enix, the company best known for its Final Fantasy series, has also branched out and made some other fantastic games, and The World Ends With You is a perfect example of that. Sure, it’s a little expensive for an iPhone game, but it is one of the best RPGs released in recent memory, so it’s well worth the cost.
10. Horn
Horn just might be the best-looking game on iOS, and that’s no small praise with beautiful games like Real Racing available on the platform. Of course, looks aren’t everything, and the third-person action RPG plays just as well as it looks. While Horn is meant for hardcore gamers, it still has a certain accessibility that will allow anyone to jump in and have a good time with the game.
