A sit-and-go tournament is a small, fast-paced poker event that begins as soon as all seats are filled. Typically featuring a single table, it follows a structured format where blinds increase at regular intervals, forcing action. Players start with equal chip stacks and compete until one remains. The prize pool is usually distributed among the top finishers, with payouts depending on the number of participants. Sit-and-go tournaments require a balance of patience, aggression, and adaptability as the game progresses.
