Roulette payouts are determined by the type of bet placed on the game. In European roulette, a straight-up bet on a single number pays 35 to 1, while a split bet on two adjacent numbers pays 17 to 1. Outside bets, such as red or black, offer a 1 to 1 payout, while column and dozen bets pay 2 to 1. Understanding these payouts is crucial for players to strategize their bets effectively and manage their bankroll while enjoying the thrill of the game. Always remember that the house edge varies, influencing overall returns.
