To participate in online roulette tournaments, you first need to register at an online casino that offers tournament play. After creating an account, you can join a tournament by paying an entry fee or using free entries, depending on the casino’s format. Once the tournament begins, each player is given a set amount of chips and competes to accumulate the most chips within a specific time limit or number of spins. Players place bets as in standard roulette, and the leaderboards track chip totals. The top players at the end of the tournament win prizes, often determined by their ranking.
