Roulette Strategy Guide — European Roulette, Best Bets, and Betting System Reality

For the high limit roulette guide (VIP Salon Privé access, Lightning Roulette high stakes), see high limit roulette guide.

Roulette strategy at Bitcoin casinos begins with one fundamental decision: European roulette (single zero — 2.7% house edge) vs American roulette (double zero — 5.26% house edge). Playing American roulette instead of European doubles the house edge with no offsetting benefit — the single most impactful "strategy" decision is choosing the right wheel. Beyond wheel selection, roulette is a fixed-odds game — the house edge is consistent across all bet types (even money bets, dozens, splits, straight-up bets all carry the same 2.7% edge on European roulette). Betting systems (Martingale, D'Alembert, Fibonacci, Labouchere) cannot overcome the house edge — they change the distribution of session outcomes (more frequent small wins vs rare large losses) without changing expected value. The only roulette bet with a different edge is the Five Number Bet on American roulette (0, 00, 1, 2, 3) — which has a 7.89% house edge, making it the single worst bet in standard roulette. This guide covers wheel selection, bet types, and the mathematical reality of betting systems.

European vs American Roulette — The Fundamental Choice

European roulette: Single zero (0). 37 numbers total (0-36). House edge: 2.70% on all bet types. Recommended: always play European roulette when available.
American roulette: Double zero (0 and 00). 38 numbers total (00, 0-36). House edge: 5.26% on all bet types (except Five Number Bet: 7.89%). Never play American roulette when European is available — no compensating advantage exists.
French roulette (La Partage rule): European wheel + La Partage rule: when 0 lands, even-money bets (red/black, odd/even, 1-18/19-36) receive half their bet back. Effective house edge on even-money bets: 1.35%. Best available roulette for even-money betting — lower edge than standard European (2.7%). Available at some Evolution live roulette tables.
Identical edge across bet types: On European roulette, the house edge is 2.7% for every bet — straight-up (35:1 pay, 1/37 probability), red/black (1:1 pay, 18/37 probability), dozens (2:1 pay, 12/37 probability). There is no "better" bet type for expected value — all carry the same 2.7% edge.

Betting Systems — What They Do and Don't Do

Martingale (double after loss): Produces frequent small wins (most sessions win a small amount) but rare catastrophic losses (when a losing streak exceeds bankroll or table limit). Expected value: exactly -2.7% per dollar bet in the long run — identical to flat betting. The "winning" sessions are paid for by the losing streak that eventually occurs.
D'Alembert (increase by 1 unit after loss, decrease by 1 after win): Similar effect to Martingale but slower escalation. Does not change expected value — same -2.7% per dollar in the long run.
What betting systems actually do: Redistribute session outcomes — more frequent small positive sessions, less frequent large negative sessions (or the reverse for negative progressions). No system can change the -2.7% expected value because every roulette spin is independent of previous results.

Frequently Asked Questions

What is the house edge of European roulette?

2.70% on all bet types (single zero wheel). American roulette: 5.26% (double zero). French roulette with La Partage: 1.35% on even-money bets (half returned when 0 lands). Always prefer European or French roulette over American.

Does the Martingale system work in roulette?

No — the Martingale redistributes session outcomes (more frequent small wins, rare large losses) but does not change expected value. The -2.7% house edge applies to every dollar bet regardless of bet sizing pattern.

What is the best roulette bet?

No bet type in European roulette has a better house edge than another — all carry 2.7%. However, even-money bets (red/black, odd/even) with the La Partage rule in French roulette reduce the edge to 1.35%. The best available bet is any even-money bet on a French roulette table with La Partage.

Should I play European or American roulette?

Always European (or French). American roulette's double zero doubles the house edge to 5.26% with no compensating benefit. Never play American roulette when European is available.

What is the Five Number Bet in roulette?

A bet covering 0, 00, 1, 2, 3 on American roulette — the only bet with a different (worse) house edge: 7.89%. The worst bet in standard roulette. Never place this bet.
