many of you might not like it or believe me, but yes, the questions, indeed, do make sense. Take the (pi)r^2 question. (pi)r^2 is the formula for the circumference of a circle. The pi part? Well, pi sounds like pie! So yes, this game does make sense. You just need to think.
I know a game just like this, but its online and I think its much better. You get to fight other people on it.
