Games for Algebra and Geometry

The other day I read a review of a game used to teach algebra called "WFF The Beginner's Guide to Modern Logic." The lady giving the review said that her algebra teacher had her class play this game for the first semester of algebra years ago, and she loved it. They played other games too, but this is one that I'm interested in trying with my family. Anyway, I just wanted to share in case there are others interested in it. Here is the website for all the games they sell at WFF.
