I have to admit that I was quite impressed by this game. It helps that I'm a guy who's into educational stuff like this. Even though mathematics was my weakest course, I still did really well with this. Of course, it wasn't very hard. I just like games that make you think. You rarely play educational games about math.
I guess we should have more of those. Granted, I'm in college and don't really need the training. This was still a very good game. While not too well drawn, it doesn't really matter. This was very fun to play.
