Besides being a fun addictive game, it will train your brain to do faster mental calculations.
The basic arithmetic calculations are covered: addition, subtraction, multiplication, and division.
At first you have "plenty" of time to answer the quizzes but the game becomes increasingly difficult. If you give fast answers, you receive small time bonuses for the quizzes to come.
