Choose your roulette variant, bet type, stake, number of spins, and starting bankroll. The simulator runs the full session instantly and shows you wins, losses, your P&L chart, and the longest losing streak you encountered. Run it multiple times to understand the range of outcomes.
European roulette has 37 pockets (numbers 1–36 plus a single zero), giving the house a 2.7% edge on all outside bets. American roulette adds a double zero, making 38 pockets and pushing the house edge to 5.26% — nearly double. All else equal, always choose European roulette when available.
Even-money bets like red/black and odd/even have the lowest variance, while straight-up single number bets pay 35:1 but win only once in 37 (or 38) spins. The house edge is the same regardless of bet type — but higher-payout bets mean bigger swings in either direction during a session.
