It's a fast paced simple math game! Your objective is to choose the RIGHT answer every time. Do not choose the wrong answer, or so help me you will lose the game... very quickly!
So that is all there is. How many right answers will you get? It gets very hard after a very short time. So think fast and choose right or you will be wrong and it will be all over red rover and the fat lady will start singing that lovely tune... wot was it? *starts to hum*
