The sports tournament that features volatile play within a confined area is often referred to as the World Series of Poker (WSOP) when considering card games. However, in physical sports, tournaments like 5-on-5 basketball in a gymnasium showcase fast-paced, intense matches. These confined areas add an element of strategy and urgency to the game. In combat sports, events like cage fighting present similar dynamics, where competitors face off in controlled environments, heightening the excitement.
