Bughouse

Two boards, four players, captured pieces passed to your partner.

Bughouse is the loudest game in any chess club. Two boards sit side by side; you and your partner play opposite colours, and every piece you capture becomes ammunition for them. It is played fast, usually with three- to five-minute clocks, and communication across the table is part of the game.

Bughouse rules

  1. 01

    Two teams of two. Partners play opposite colours on adjacent boards.

  2. 02

    A piece you capture is handed to your partner, who may drop it on an empty square on their board as a full move.

  3. 03

    Pawns cannot be dropped on the first or eighth rank; a captured promoted pawn reverts to a pawn.

  4. 04

    The game ends as soon as either board ends — one checkmate or flag fall decides the whole match.

  5. 05

    Talking to your partner is allowed and expected ('don't trade your knight', 'I need a bishop').

How it changes your play

You are not playing your own board in isolation. Trading a knight can lose your partner the game if their king has a hole a knight can reach.

The clock is a weapon. Sitting on a move to deny your partner a piece — or to wait for one — is a core Bughouse skill.

Etiquette

Announce what you need and what you are about to give away. Silent Bughouse is losing Bughouse.

Never physically reach across to your partner's board; place captured pieces in the agreed spot between the boards.

Questions about Bughouse

How many chess sets do I need?
Two full sets and two clocks. Online, both boards are shown side by side automatically.
Can we play Bughouse with three players?
No — the game structurally needs four players on two boards. For a drop-mechanic game with two players, play Crazyhouse instead.
