🧮 How Roulette Works

European Roulette: 37 pockets (0-36). Probability of winning a straight bet = 1/37 ≈ 2.70%. Payout 35:1.

American Roulette: 38 pockets (0,00,1-36). Probability of winning straight = 1/38 ≈ 2.63%. Payout 35:1.

House Edge = (Total Pockets – Winning Pockets × Payout) / Total Pockets

For European red: (37 – 18×2)/37 = (37-36)/37 ≈ 2.70%. For American: (38 – 18×2)/38 = (38-36)/38 ≈ 5.26%.
