Great for adults too!

I've always had trouble with college algebra, this "game" has made problems much easier.
I didn't even realize how I knew what to do when I started zipping through homework problems until I revisited the game and it started looking familiar.
Please make an updated version of this game with more/new puzzles! I've played it so often (both a and b sides) that I've almost memorized the current set of puzzles!
