Traffic Rush is a fun, fast-paced, cartoony arcade game in which you must direct traffic at a busy four-way intersection--much like other "traffic control" games. The touch interface is easy and natural, with you swiping vehicles to speed them up or tapping them to temporarily stop them. You have to choreograph a colorful collection of trucks, motorcycles, and various passenger cars, all with different speeds (and sound effects), and the number of vehicles--and, inevitably, close calls--increases as the game progresses. Your game ends when you fail to avert a crash, and you're given your score, average vehicle speed, and round duration, which you can then post to an online leaderboard.
The game's addictive gameplay and peppy presentation (even with its collisions, featuring crash sounds and broken glass) make it a must at this price. If Traffic Rush gets more maps and extras, to add some heft to its otherwise minimal schtick, this game could also fare well as a paid download.
