Choose Easy for simple addition and subtraction, Medium for multiplication and squares, or Hard for trickier combined patterns. Type your answer and press Check or Enter. If you are right, you earn points and your streak grows. If you are wrong, the pattern is revealed so you can learn it. Your score, streak and best streak are all tracked.
