Roulette

European vs American roulette: always play single-zero

Before you place a chip, check the wheel — it is the single biggest decision in roulette. A European (single-zero) wheel has 37 pockets, numbers 1–36 plus a single zero, and a house edge of about 2.7%. An American (double-zero) wheel adds a second green pocket (0 and 00) for 38 pockets, which pushes the edge to roughly 5.26% — nearly double, for the exact same game. There is no upside to the American wheel; always choose single-zero where you can.

French roulette goes one better. It is a single-zero wheel with “la partage” (or “en prison”) rules, which return half of a losing even-money bet when the ball lands on zero. That roughly halves the edge on those bets to about 1.35% — the best odds roulette offers. If you have the choice, French rules on a single-zero wheel is the smart table.

The bets and their odds

Roulette bets split into two groups. Inside bets sit on specific numbers — a straight-up single number pays 35:1, with splits, streets and corners paying less for covering more. Outside bets cover big groups: red or black, odd or even, high or low (each paying 1:1), plus dozens and columns (2:1). Here is the key point people miss: every one of these bets carries the same house edge, because that edge comes entirely from the zero(s). Spreading chips across the table changes your variance — how wild the swings feel — not the long-run maths. Outside bets win more often for less; inside bets win rarely for more. Neither is “better value”.

Why betting systems fail

No staking system beats roulette — full stop. The most famous, the Martingale, tells you to double your bet after every loss so a single win recovers everything. It feels bulletproof and it is not. Each spin is independent, so a run of losses is always possible, and doubling grows your stake exponentially: a handful of losses in a row and you are betting a fortune to claw back a tiny profit. In the real world you hit the table limit or run out of money first, turning a bad streak into a fast, total loss. The D’Alembert, Fibonacci and every other progression share the same fatal flaw: they rearrange when you bet, never the negative expectation underneath. Treat any “system that beats roulette” as a myth to avoid, not a plan.

RNG, live-dealer and provably-fair roulette

Software (RNG) roulette spins a virtual wheel driven by an audited random number generator — fast, low-stakes, and fine for casual play. Live-dealer roulette streams a real wheel and croupier in real time, which feels closer to a casino floor but runs slower and at higher minimums. If the wheel and rules match, the house edge is identical — the difference is atmosphere and stakes. Some crypto casinos also offer provably-fair roulette, where you can verify the result was not altered after your bet; useful transparency, but read provably fair, explained for what it does and doesn’t guarantee (it proves the spin was fair, not that the edge is gone).

Bonuses and wagering: roulette usually counts low

Like most table games, roulette typically contributes very little toward bonus wagering requirements — often only around 5–10%, and sometimes it is excluded entirely or can void a bonus if you bet above a cap. Slots usually count 100%. So a headline welcome offer can be almost impossible to clear on roulette alone. Always read the bonus terms first, and run the maths in our wagering calculator alongside our guide to wagering requirements.

Playing roulette responsibly

Even the best roulette table — single-zero with French rules — keeps a house edge, so the long-run expected outcome of wagering is a loss, and no bet selection or system changes that. Decide what you can afford to lose before you start, treat it as the price of the entertainment, never chase losses, and walk away when the budget is gone. You must be 18 or older (or the legal age where you live). If it stops being fun, free and confidential help is on our Responsible Gambling hub.

Roulette and the Jackpot Score

When we review a casino, its roulette and wider table-game range feeds Game Selection, one of the six sub-scores behind every Jackpot Score (weighted at 15%). We look for single-zero and French tables, a good spread of live-dealer options, and provably-fair variants where offered — not just the presence of a wheel.
