Cup tournaments are competitive events where teams or individuals compete in knockout-style matches. In this format, teams face off in single-elimination rounds, meaning that the losing team is eliminated from the tournament while the winning team advances to the next round. This continues until one team remains, crowned as the champion. These tournaments can be found in various sports, including soccer, basketball, and hockey. They often feature a mix of professional and amateur teams, creating exciting matchups. Popular examples include the FIFA World Cup in soccer and the NCAA Basketball Tournament in the United States.
