A popular game in many math circles is the card game SET. Invented in 1974 by a population geneticist, Masha Jean Falco, this game has gained popularity and is accessible to all people, young and old (even those not mathematically inclined). It is a game of visual perception, matching and identification. You can visit the website http://www.setgame.com/set/puzzle to play a daily puzzle for free and practice your skills before my talk. They also sell many creative games on this website if you are interested. I, personally, have not written a mathematically themed paper on this topic, but I will outline topics in a paper written by Elizabeth McMahon, Rebecca Gordon and Hannah Gordon. There is a mathematical structure to the game that bring you insight and enjoyment. I have a set game in my office and I encourage you to stop by and play.
