Game Description:It's time to get your math on! Professor Kageyama (of Brain Age fame) is back, and this time, he's going to have you bending your brain around basic math skills like addition, subtraction, and multiplication. You'll use the original grid-based system to learn how to do math in your head, or just to get a refresher course on skills you already have. Different tests will keep you working on building up your capabilities, and you can compete with up to 16 different opponents on a single cartridge. You can even try to beat their best scores and keep your name at the top of the leaderboard. There are over 45 different tests to challenge you at your leisure!
