Despite the iPhone’s lack of a d-pad and other hardware controls, it is very popular as a gaming device. Part of its popularity is due to its excellent connectivity features, which include Bluetooth, Wi-Fi, 3G, and Push notification. These features support wireless multiplayer games, and there are currently more that 200 of these games available in the App Store.
There are two main types of wireless games. The first type, local games, allows two or more users in close proximity to play against each other. The second type communicates over the Internet with a central server allowing users on the other side of town or around the world to play against each other. Both approaches have their respective strengths.
