The game of Set has proved to be a very popular game at our college mathematics club meetings. Since we started playing, the membership has grown every month. In fact, one of our members brought her sixyear- old son to a meeting, and he now looks forward to playing Set with us. As a result of playing the game in our club and thinking about the results, we created and solved a variety of mathematical questions. For example, we wondered about possible strategies for winning and conjectured about phenomena that happened when playing. These questions involve a wide variety of traditional mathematical topics, including the multiplication principle, combinations and permutations, divisibility, modular arithmetic, and mathematical proof.
