If you believe that a game of chess is just too simple, imagine the fun of keeping up with the strategy of two opponents at once! This 3 Man Chess board is circular, so you're all starting at the same disadvantage. From the product description:
Play chess with 3 people at the same time with this three player chess game. Without compromising any of the rules, strategy, or fun of Chess, this variant board has been developed that accommodates three players. The only changes from conventional chess are some protocol issues that must be followed to maintain order where the teams border each other, which is simple and necessary. The complexities of the third player are infinite. Your threatened piece may be allowed to maintain occupancy as your position is beneficial to the threatening player. But how long can it last? This scenario may exist all over the board. There are multiple trust and doubt situations among all players.
This board and 48 playing pieces (in ivory, black, and gray) is available at Amazon. Although I could see myself having a lot of problems with it, my first problem would be finding two other people who know how to play chess and who are willing to try it. -via Geeks Are Sexy
