Roulette tournaments are competitive events where players compete against each other to accumulate the highest amount of chips within a set time or number of spins, rather than playing directly against the house. Each participant starts with the same number of chips and places bets as usual on a shared roulette table. The objective is to build the largest chip stack by the end of the tournament. Winners are determined by their chip totals, and prizes are awarded based on final rankings. These tournaments often feature entry fees and provide a social, competitive twist on traditional roulette.
