Save for the cheesy name, World's Ultimate Brain is quite a well-put-together puzzle game for Android. It tests your brain's speed and agility across four different categories: Calculation, Memory, Visual Recognition, and Logic. Your simple job is to race the clock and answer as many questions correctly as possible. Once you finish, the app will calculate your score, and submit it to the worldwide leaderboard. If you're extra proud of your intellectual skills, you can even have it post your score to Facebook, Twitter, or (inexplicably) MySpace.
While World's Ultimate Brain is indeed fun, easy to play, and stable, we do wish it offered a greater variety of questions to test our mental agility across more than four categories. As it is, with so few question types, it's highly likely we'd eventually get bored with the repetitive game play.
Otherwise, we think World's Ultimate Brain is a nice piece to add to your app drawer, if you're into puzzle games and brain teasers. Sure, its developers need to add more question types, but in the meantime, that countdown timer is still a formidable foe.
