Chessboxing is a sport that combines chess and boxing. The game consists of alternating rounds of chess and boxing, with a total of 11 rounds. There are six rounds of chess and five rounds of boxing, each round lasting three minutes.

In the chess rounds, the players take turns making moves on a standard chessboard. Each player has 12 minutes to make all their moves. If a player makes an illegal move, their opponent is awarded two extra minutes on their clock. If a player runs out of time, they lose the game.

In the boxing rounds, players wear gloves and protective gear and try to knock out their opponent or win by decision from the referee or judges.

If the game is tied at the end of the 11 rounds, a tiebreaker round of chess is played with a time control of five minutes per player. If the game is still tied after the tiebreaker, an additional sudden-death round of boxing is played, and the first player to land a scoring blow wins.

To ensure fair play, there are specific rules related to conduct and behavior. Players are not allowed to use physical or verbal abuse, nor are they allowed to use any devices to communicate with others during the game.
