description Bughouse Overview

Bughouse is a four-player team chess variant played across two separate chessboards. When a player captures an opponent's piece on one board, they pass it to their teammate, who can then use a turn to drop that piece onto an empty square on their own board. Played primarily at fast time controls, the game emphasizes communication and aggressive tactics aimed at creating checkmating threats through piece drops. It is popular in informal chess club settings and online platforms.

help Bughouse FAQ

How do you play the chess variant Bughouse?

Bughouse is a fast-paced team game played on two adjacent chess boards, where partners sit next to opposing players. When a player captures an opponent's piece, they pass it to their teammate, who can then "drop" that piece onto an empty square on their board as their turn instead of making a standard move.

What happens if a player's clock runs out in a Bughouse match?

Because Bughouse is almost universally played with chess clocks (usually at fast time controls like 3-minute or 5-minute blitz), if either player on a team runs out of time, the entire team loses the match. This prevents players from intentionally stalling to protect their teammate.

Is Bughouse an officially rated chess variant by FIDE?

No, Bughouse is not officially recognized by the International Chess Federation (FIDE) for standard rating purposes. However, it is highly popular at local chess clubs and online platforms like Lichess, which hosts dedicated Bughouse servers.

Can you drop a piece to deliver checkmate instantly in Bughouse?

Yes, you can drop a captured piece onto almost any empty square to deliver check or even checkmate, which makes "piece drops" incredibly dangerous. The only restriction is that you cannot drop pawns onto the first or eighth ranks, as that would allow illegal promotion mechanics.
