Bughouse chess (also known as Exchange chess, Siamese chess, Tandem chess, Transfer chess, Double bughouse, Cross chess, or simply bughouse or bug) is a popular chess variant played on two chessboards by four players in teams of two. Normal chess rules apply, except that captured pieces on one board are passed on to the players of the other board, who then have the option of putting these pieces on their board. The match ends when either of the games on the two boards ends. A game is won when one player gets checkmated, resigns, forfeits on time or when an illegal move is made in which the offending side is caught. The match can be drawn by agreement or when two players run out of time or are checkmated simultaneously. A piece cannot be inserted into the board for a checkmate, but check is allowed.
