A round robin format is a type of tournament in which each participant plays every other participant the same number of times, accumulating points as they win. This format contrasts with an elimination tournament, where participants are eliminated after a certain number of losses. In a round robin tournament, each competitor has an equal opportunity to face off against all of their opponents, creating a fair and equitable playing field for participants. This format is commonly used in sports with a large number of competitive matches per season, such as most association football leagues in the world, which are organized on a double round-robin basis. Round robin tournaments can also be used for league schedules or tournaments that guarantee a certain number of games. The advantages of a round robin tournament include:

• Every player or team gets the opportunity to compete against all other participating competitors, even if they have a bad match.
• Competitors can accumulate points throughout the tournament based on their performance in each match, rather than being eliminated after a certain number of losses.
• This format is fair and equitable, as each competitor has an equal opportunity to face off against all of their opponents.

However, round robin tournaments can be time-consuming, especially if there are a large number of teams or participants.
