Apple’s iTunes Store has a new game for iPods called Brain Challenge. It costs US$4.99. Brain Challenge is billed as a “vitamin boost for your brain,” and a “personal coach” used to keep your brain alert. It includes 20 different mini-games set up in five categories designed to test your brain’s abilities: Visual, Memory, Logic, Math and Focus.

The Daily Brain Test puts you through five random three-minute mini games, stats and graphs that show you your performance, and a “creative mode” that helps you exercise your artistic abilities.
