About the game
Brain Buster puts you and a rival brain in an arena with one math problem on the board and four answers under it. Add, subtract, multiply, divide. Hit the right one first and you land a punch that sends the other brain spinning. Pick wrong and your opponent gets a free shot. Ten seconds with no answer and nobody scores.
Win more of the 14 questions and you take the match. Quick Play pits you against a bot that gets faster as you level up, and VS Online matches you with a live player on the same clock.
