Wheel Variants Compared
Online casinos offer three main roulette formats. The number of zero pockets directly determines the house edge, making wheel selection the most impactful decision you can make before betting.
| Variant | Zeroes | House Edge | Best For |
|---|---|---|---|
| European | 1 (0) | 2.70% | Standard play |
| French | 1 (0) | 1.35% | Even-money bets |
| American | 2 (0, 00) | 5.26% | Avoid if possible |
French roulette applies La Partage or En Prison rules on even-money bets. When zero hits, you lose only half your stake (La Partage) or your bet is imprisoned for the next spin (En Prison). This halves the effective house edge to 1.35%.
Inside and Outside Bets
Inside bets target specific numbers or small groups on the layout. A straight-up bet on a single number pays 35:1 but wins only 2.7% of the time on a European wheel. Split, street, corner, and line bets cover multiple numbers with proportionally lower payouts.
Outside bets cover larger sections: red/black, odd/even, high/low (1-18/19-36), dozens, and columns. These pay 1:1 or 2:1 and win more frequently, making them the sensible entry point for new players learning the flow of the game.
RNG vs Live Roulette
RNG (software) roulette uses a certified random number generator to determine outcomes instantly. You control the pace — spin as fast or slow as you like. Stakes typically start from 10p, and many operators offer free demo modes.
Live roulette streams a real wheel operated by a human dealer. Betting windows open for a set period, then the dealer spins. The experience is slower but more immersive. Evolution's Lightning Roulette and Immersive Roulette add multipliers and camera angles that RNG versions cannot replicate.
Common Betting Approaches
No betting system overcomes the house edge long-term. Martingale (doubling after losses) risks hitting table limits during extended losing streaks. Fibonacci and D'Alembert progression systems reduce stake escalation but still cannot change the mathematical disadvantage.
The most effective approach is flat betting — wagering the same amount each spin within a predetermined session budget. Combine even-money outside bets on European or French wheels for the lowest house edge, and treat any session profit as a bonus rather than an expectation.
UK-Specific Considerations
All roulette at UKGC-licensed sites uses certified fair outcomes. Bonus wagering often restricts roulette contributions to 10-20% of each bet, or excludes it entirely. Check bonus terms before playing table games with promotional funds.
Set deposit limits before playing and use reality checks offered by the operator. Roulette's fast pace can deplete a bankroll quickly — decide your maximum loss before the first spin and stop when you reach it.
