Four-player chess (also known as four-handed chess) is a family of chess variants played with four people. The game features a special board typically made of a standard 8×8 square, with 3 rows of 8 cells each extending from each side, and requires two sets of differently colored pieces. The rules are similar to, but not the same as, regular chess. The goal is to have the most points at the end of the game. In the free for all variant, every player for themselves. (wikipedia.org)
