Bughouse

Bughouse (or siamese chess) is a variant of chess played between two player teams on two separate boards. The special feature of the game is that pieces you capture are transferred to your partner, who is playing with the opposite color pieces from yourself. He may "drop" such a piece on an empty square as a subsequent move in his game.

STARTING A BUGHOUSE MATCH

Pieces taken by one player automatically appear in the captured pieces display of his partner and can be dragged onto the board as a move. Between the two game boards is a one-click messaging system with which you and your partner can seemlessly communicate.
