Roulette is one of the oldest casino games and one of the easiest to play. The math, however, depends entirely on which wheel you pick. Single-zero European roulette has a 2.7% house edge. Double-zero American roulette has a 5.26% house edge — almost twice as expensive. Always play European.
Roulette variants
European — 37 pockets (1-36 plus single 0). House edge 2.70%.
French — same wheel as European but with the La Partage or En Prison rule on even-money bets. La Partage refunds half your stake on a 0; En Prison locks it for one more spin. Effective house edge on even-money bets drops to 1.35% — the best wheel in the casino.
American — 38 pockets (1-36 plus 0 and 00). House edge 5.26%. Avoid.
Bet types
Inside bets: straight (single number, 35:1), split (two numbers), street (three), corner (four), six-line. Outside bets: red/black, even/odd, high/low (1-18 / 19-36), columns, dozens. All have the same long-run expected loss except for those affected by La Partage.
Strategy reality check
No betting system can change the house edge. Martingale, Fibonacci, D'Alembert — they all have the same negative expected value as flat-betting. They feel different (smaller variance, occasional table-limit busts) but the math is identical.
The only 'strategy' that matters is variant selection: French roulette with La Partage on even-money bets is the best play in the casino on a per-spin basis.
Live dealer roulette
Lightning Roulette, Immersive Roulette and Speed Auto Roulette from Evolution Gaming are excellent. Lightning adds 50× to 500× multipliers on selected straight numbers, with a slight RTP cost (~1% added house edge). Fun, but stick to standard European tables for the best math.
