Aside from the singleplayer, Pixel Machines also allows players to battle it out against each other in online multiplayer modes. Online play is rarely seen in a game that only costs 99 cents.
If you buy the mobile iOS version of Pixel Machines, you'll also be able to play the game on an Apple TV device with adjusted controls and gameplay on a bigger screen. The Apple TV version also improves the multiplayer by allowing up to 8 people to play in a head-to-head multiplayer mode.
Fruit Ninja has a local multiplayer mode available on the iPad version. The screen is split in half with 2 single-player games going on at the same time. The first player to make 3 mistakes loses.
