The [[algebraic chess notation]] for [[chess]] can be used to record moves in bughouse games.
Different notations for piece drops are possible.<ref>Manson and Hoover (1992) use an "x" (as used in captures) in front to indicate a piece drop, as in xNf1. Penn and Dizon (1998) use the "I" (for insert) in front as in INf1. Von Zimmerman (2006) uses the @-notation.</ref> The [[internet chess server]]s [[Free Internet Chess Server|FICS]] and [[Internet Chess Club]] use the at-sign [[@]], as in N@f1 (knight drop at f1), Q@e6+ (queen drop with check at e6) or P@h7# (pawn drop with checkmate at h7).

Because of the fast pace at which the game is played, bughouse games are rarely recorded
in games played over the board. With the arrival of [[#Online|online chess]] it has become possible to systematically record games.<ref>Two large bughouse databases are [http://www.bughouse-db.org Jamesbaud's database] and [http://www.bughouse.be/database.html Lieven's database] {{webarchive |url=https://web.archive.org/web/20070927030525/http://www.bughouse.be/database.html |date=September 27, 2007 }}.Accessed July 31, 2007.</ref> The format in which this is done is the bughouse portable game notation (BPGN), an extension of the [[Portable Game Notation]] for chess.<ref>[http://www.bughouse.be/BPGN_Standard.txt Specification of the BPGN format from bughouse.be].
