There is now a world of games that can be downloaded to the iPhone, thanks to many developers creating original titles and porting games from other platforms. The types of games found on the main game systems can be found right on the iPhone like strategy, action, role playing (RPG's), classic arcade, sports, shooting, puzzle, trivia, and word games. Before you waste time and money on any game, be sure to read a review so you'll know what to expect. Sometimes the most simplest iPhone game can be the most fun, but they can also be the worst. Reading up on an in-depth review or iPhone game guide will help you decide what's playable and what isn't.
