How to play
Crazy House
Similar to Bughouse chess, but for two players. Captured pieces are dropped back on to the board.
Introduction
Crazy House rules are the same as Standard Chess but with the addition of piece drops, which become available after a capture is made.
Starting Position
This variant is played from the standard starting position of Standard Chess.
Moves of the Pieces
Pieces move as in Standard Chess, but captured pieces can also be dropped on to the board from a pocket where captuered pieces are retained.
White can drop captured pieces on to the board rather than making a regular move.
Capturing
As a piece is captured it flips color before being kept in a pocked for a drop on a subsequent move.
Captured promoted Pawns are added to the pockets as Pawns , not the promoted piece.
Drops
Captured pieces can be dropped on to the board instead of making a regular move.
Dropping a piece that would give checkmate immediately is permitted, as is dropping a piece to block what would otherwise be checkmate.
