Game: Kartrider Pit

Though it has its flaws, Nexon's KartRider Dash is a pretty brilliant game. Everybody loves Mario Kart-style mascot racers, and nothing beats hooking up on Facebook to slam your Aunt Matilda with a missile ("This is for that lousy sweater you sent last Christmas—BAM!") But weapon-armed go-karts take a savage beating on the racetrack, so a swift, savvy pit crew is essential to the karting experience. KartRider Pit is an iOS time-management game that takes the KartRider crew off the track and into the pit.
