A bracket system is a method used to organize and manage competitions, particularly in sports and tournaments. It divides participants into pairs or groups, allowing them to compete against each other in a structured format. Winners advance to the next round, while losers are eliminated, creating a clear path to determine the overall champion. This system is commonly seen in events like March Madness, where teams compete in a knockout format. Each round narrows down the field until a final match determines the winner. Bracket systems can also be applied in other contexts, such as single-elimination tournaments or playoff series.
