Who would have ever believed that solving math problems, counting syllables and doing memory puzzles would be a fun and addictive video game? "Brain Age" is certainly not a typical game, but it's the leader in Nintendo's new philosophy of reaching out to a different audience. By rapidly doing simple math and other brainteasers, you'll learn your brain's "age." The goal is to get it down to 20 - which isn't as easy as you'd think. Designed to be played for just moments per day, "Brain Age" also includes a large number of Sudoku puzzles for those times when you're not quite ready to quit.
