We're not about to expect a great deal from movie tie-ins, especially ones clearly geared at kids, so when we say that the DS version of Cars is designed for people with three-second attention spans, that's not such a bad thing. You'll find no circuits to race or world to explore as in the console versions - instead, it's a collection of touch-screen minigames that range from cute to "time to break the DS" annoying.
Initially, only three games are available. Once you successfully complete them, more open up and so on. They're basic things like matching color patterns (like the game Simon ), rubbing cars to refuel them or dragging trophies into their correct locations as they spill out of a runaway semi truck.
While the games aren't necessarily bad, they're excessively repetitive and drag on too long. After four rounds of tapping the screen to launch Mater into the atmosphere, we're done. No round five, please. And the Piston Cup racing mode seems to rely more on chance than skill, as your opponent (Chick Hicks) flails around the track, wildly accelerating and slowing down for no reason.
