Roulette House Edge Explained

European Wheel House Edge

Single-zero mathematics.

European single-zero roulette features 37 pockets (0-36). Even-money bets like red/black win with probability about 48.65%, giving the casino roughly 2.70% house edge on most bets.

Edge calculation:

Fair payout for 18/37 win rate would be 19:18 (approximately 1.055:1).

Actual payout is 1:1 creating shortfall.

The difference between fair and actual payouts creates 2.70% roulette house edge.

This applies to straight-ups, splits, corners, and all standard bets maintaining consistent casino advantage.

American Wheel House Edge

Double-zero disadvantage.

American double-zero roulette has 38 pockets (0-36 plus 0 and 00). Even-money bets win about 47.37% of the time, so the house edge jumps to 5.26% nearly doubling the casino advantage.

Why it's worse:

Additional pocket reduces all win probabilities proportionally.

Payouts remain identical to European despite worse odds.

The extra 00 nearly doubles roulette house edge making American significantly less favorable.

Examples from your games include American Roulette (NetEnt) and First Person American Roulette (Evolution) clearly signaling American-edge formats to avoid when possible.

Triple-Zero Wheels

Extreme disadvantage versions.

Triple-zero wheels adding a third zero push the edge to around 7.69%, which most strategy writers advise avoiding altogether as these represent terrible value.

Triple-zero problems:

39 total pockets dramatically reducing win probabilities.

Payouts still identical to European and American.

Roulette house edge reaches nearly 8% making them worst standard roulette available.

Rarely found online but occasionally appear in physical casinos targeting uninformed players.

La Partage and En Prison Rules

European edge reducers.

Special rules available on some European wheels reduce roulette house edge further on even-money bets from 2.70% to 1.35%.

La Partage:

When 0 hits, even-money bets lose only half stake.

Effectively cuts house edge in half on affected bets.

En Prison:

Even-money bets "imprisoned" when 0 hits.

Next spin resolves imprisoned bet creating second chance.

Both rules significantly improve player odds making these games highly desirable when available.

Identifying Wheel Types

Knowing what you're playing.

Many of your games clearly signal wheel type in the name or rules helping you make informed decisions.

American-edge games:

American Roulette (NetEnt), First Person American Roulette (Evolution) explicitly indicating 5.26% house edge through naming.

Single-zero games:

European-style games like Dynamic European Roulette, European Roulette VIP, European Roulette, Roulette Nouveau, Royal Riches Roulette, Fortune Roulette, Lucky Roulette, Penny Roulette, Low Stakes Roulette, 20p Boost Roulette which are the better long-term choice offering 2.70% roulette house edge.

Check game info panels when wheel type isn't obvious from naming.

House Edge Across All Bets

Consistency within wheel types.

European consistency:

All standard bets (straight-up, split, street, corner, dozen, even-money) maintain 2.70% roulette house edge.

La Partage or En Prison reduces to 1.35% on even-money only.

American consistency:

All standard bets carry 5.26% edge except basket bet.

Basket bet (0-00-1-2-3) has 7.89% edge making it worst bet available.

The mathematical structure ensures uniform casino advantage regardless of betting pattern.

Expected Loss Calculations

Real money implications over time.

Example scenarios:

Wagering $1,000 on European roulette: Expected loss $1,000 × 2.70% = $27.

Wagering $1,000 on American roulette: Expected loss $1,000 × 5.26% = $52.60.

American version costs you $25.60 more for identical entertainment.

The roulette house edge compounds across extended play sessions making wheel choice financially significant.

Multiplier Game Edge

Enhanced variants maintain advantage.

Games with multipliers like Dynamic Roulette 120x, Vegas Roulette 500x, Virtual Vegas/Space/Monaco variants, Lightning series, Multifire versions maintain base roulette house edge.

Multiplier mechanics:

Boosted payouts on some outcomes compensate through reduced standard payouts.

Overall RTP remains approximately 97.30% (European base) or 94.74% (American base).

Roulette house edge doesn't disappear just redistributes across possible results.

The excitement comes from variance redistribution not improved player odds.

Long-Term Impact

Cumulative effect over sessions.

Annual comparison:

Playing 200 hours yearly wagering $50/hour ($10,000 total).

European expected loss: $10,000 × 2.70% = $270.

American expected loss: $10,000 × 5.26% = $526.

Choosing American costs $256 extra annually.

The roulette house edge compounds significantly over lifetime play making variant selection critical for regular players.

No System Beats Edge

Mathematical reality unchanged.

Betting systems like Martingale, Fibonacci, or D'Alembert cannot overcome roulette house edge as they only change short-term variance not long-term expectation.

Why systems fail:

Progressive betting doesn't improve odds.

Table limits prevent infinite progressions.

Roulette house edge applies to every bet regardless of sequence.

Expected loss remains constant based on total wagered.

Systems provide structure and discipline but don't create mathematical advantages.

Minimizing House Edge

Practical player strategies.

Best practices:

Choose European over American wheels (2.70% vs 5.26%).

Seek La Partage or En Prison rules when available (1.35% on even-money).

Avoid triple-zero wheels entirely (7.69% edge).

Never bet American basket (7.89% edge worst available).

These choices significantly reduce roulette house edge faced improving long-term expected value.
