I played Aargon Deluxe for PC and loved it – Aargon Review

While this iPhone version lacks the cool funky tunes of the PC version and is limited by the screen size, it does a very polished job of bringing the same brain-teasing experience to the leading mobile market. The PC version had a wonderful tutorial which explained everything and really flattened the learning curve. I think this version is a bit less approachable for newbies, but it's perfect for those already familiar with the game.
