Tournament rounds are specific segments of a competitive event where participants compete against each other to advance to the next stage. Each round typically consists of matches or games, and the outcomes determine which players or teams move forward in the tournament. The structure can vary, with formats like single elimination, double elimination, or round-robin. In many sports and games, such as tennis or chess, tournament rounds are crucial for determining the overall champion. Players accumulate points or wins, and the best performers progress through the rounds until a final match decides the winner.
