Swiss round robin system, also known as "Swiss system" or "Swiss lottery system", is a group lottery method used in competitive competitions, aiming at ensuring that each player faces an opponent with equal strength in the competition, thus achieving fairer competition. Although it was first widely used in board games, it has now been extended to various competitive sports such as bridge, Go and e-sports.
The name of the Swiss round robin system originated from the place where it was first applied, that is, the Swiss chess championship at the end of 19. Dr Julius Muller, the referee of the Swiss Chess Championship and the founder of the Swiss Chess Association, created this unique competition system. Its innovative concept is to ensure that all players have equal opportunities in the competition and will not be eliminated in advance.
