The App Store is a wonderland of diverse gaming goodness, including deeply absorbing role-playing and strategy games, gripping narrative experiences, and titles that let you build up a character and skills over a large stretch of time. But for many of us, the games we turn to the most are the ones that offer immediate, short-term thrills – the games we can play for a few minutes at a time with minimal hassle, but which are entertaining and engrossing enough to play for much longer when desired. For those needs, we present the 25 best quick-hit games for iPhone and iPod touch, all of which let you play a game, level, race, or round in a few minutes or less. When you need to fill a short stretch of your day, these are the games you'll want.
