Roulette is one of the simplest casino games to understand and one of the most important to understand correctly from a house edge perspective. The single most important roulette decision is which wheel to play: European roulette (single-zero, 37 pockets) has a 2.70% house edge; American roulette (double-zero, 38 pockets) has a 5.26% house edge — nearly double. Always play European roulette if available. This single choice halves the casino's advantage over you.
This guide covers the European vs American roulette house edge in full, the La Partage and En Prison rules (which reduce European roulette house edge to 1.35% on even-money bets), the best and worst roulette bets by house edge, live dealer roulette formats at crypto casinos (including Lightning Roulette and Immersive Roulette), betting system mechanics, and high-limit roulette for crypto players.

European Roulette (single-zero): 37 pockets: numbers 1–36 + single zero (0). House edge: 2.70% on all bets. On a $1,000 spin on red/black, the expected cost is $27. European roulette is available at all major crypto casinos in both RNG and live dealer formats.
American Roulette (double-zero): 38 pockets: numbers 1–36 + 0 + 00. House edge: 5.26% on all bets except the 5-number bet (0-00-1-2-3) which has a 7.89% house edge (the worst bet in the casino, never place this). On a $1,000 spin, the expected cost is $52.60 — nearly double European. There is no mathematical reason to play American roulette when European is available. American roulette is common at US-facing casinos; European is standard at crypto casinos.
La Partage rule (French roulette): Under La Partage, when the ball lands on zero, half of even-money bets (rouge/noir, pair/impair, passe/manque) are returned to the player. This reduces the house edge on even-money bets from 2.70% to 1.35% — making French roulette with La Partage the best available roulette game by house edge. Available at some live dealer tables (typically labelled "French Roulette" or "Double Ball Roulette"). Check whether La Partage applies at your specific table.
En Prison rule: Similar effect to La Partage — when zero hits, even-money bets are imprisoned for one more spin rather than immediately returned. If the imprisoned bet wins on the next spin, it is returned (no profit); if it loses, it is lost. Statistical effect on house edge: identical to La Partage (1.35% on even-money bets). En Prison is less common than La Partage at crypto casino live tables.

Best and Worst Roulette Bets — Outside vs Inside
All European Roulette bets have the same 2.70% house edge: Unlike blackjack, where different decisions have different house edges, all standard European roulette bets have identical house edge. Red/black (1:1), dozens (2:1), columns (2:1), corner (8:1), straight-up single number (35:1) — all 2.70% house edge. The choice of inside vs outside bets is purely a volatility choice, not an EV choice.
Outside bets (lower volatility): Red/black, odd/even, high/low (1:1 payout), dozens, columns (2:1 payout). These bets win more frequently — red/black wins approximately 48.65% of the time on a European wheel. Good for extended sessions without large swings.
Inside bets (higher volatility): Straight-up (35:1), split (17:1), street (11:1), corner (8:1), six-line (5:1). Straight-up wins approximately 2.70% of the time — very infrequent, but pays 35× when it hits. Good for players seeking large peak wins with the same theoretical house edge.
Avoid the 5-number bet: The 0-00-1-2-3 bet on American roulette pays 6:1 but covers 5 numbers on a 38-number wheel — house edge 7.89%. This is the only bet in standard roulette with a uniquely higher house edge than all other bets. Never place this bet.
