With the absence of an [[International Federation]], over-the-board competitive bughouse is very much in its infancy. While there is no over-the-board [[world championship]], an online world championship is sponsored by chess.com.<ref>{{Cite web|url=https://lichess.org/forum/team-bughouse-world-championship/2021-bughouse-world-championships#6|title = 2021 Bughouse World Championships!}}</ref> Participants in the 2021 tournament included Grandmasters [[Nils Grandelius]] and [[Jeffery Xiong]].
