Watch out for numbers falling from the top of the black board. Shoot them with spheres, triangles and squares as they head towards the red line. The higher the number, the faster it falls and the more scores you get for hitting it. If they reach the red line, it's algebra time! You have a total of one minute to solve you arithmetics, but time does not reset after you answered. If you answer correctly, the game goes on. If you pick a wrong answer, game's over. So be fast, but be sure!
With increasing score the falling numbers spawn faster, while you're running out of time a bit more with every term you solve. Don't let the speed and pressure get the best of you! Keep cool and do Maths!
