The App Store offers a wide variety of paid and free iPhone game apps—so many, in fact, that it's divided into 19 subcategories to help you find what you're looking for. Apple showcases the best in sections titled New and Noteworthy, What's Hot, Made For iOS4, What We're Playing, Five Minute Fixes, Top Paid Apps, and Top Free Apps. Generally, paid games have more complex graphics, more levels, and longer playing time. Many of the best games are frequently updated by the developers, incorporating new levels, better graphics, and, sometimes, new modes of gameplay. The free games are still a lot of fun, but they tend to be a bit simpler. Some of the free games are "Lite" versions of paid games, designed to give you a taste of what you can expect if you decide to buy the full version. Most of the games will keep track of your high scores and some will even let you post your scores to your favorite social networks or enter them in a central database so you can see how you stack up against the competition.
