Online roulette is the digital version of the best-known casino game. A wheel with numbered pockets, a small ball and one simple question – where will it stop? Online you can play it as a computer game driven by a random number generator or as live roulette with a real dealer. The rules are the same, but the differences between variants directly affect your chances.
In this article we explain the roulette rules, compare the European, French and American versions, show the titles with the highest RTP and suggest where to play. Roulette is for players aged 18 and over only, and it is a game of chance – no system guarantees a win. Play responsibly.
Online roulette: best casinos 2026
You will find roulette at almost every online casino, but the number of variants and the availability of live tables differ.
| Casino | Licence | Roulette selection | Table / live roulette |
|---|---|---|---|
| Tipsport | ÚRHH | 10+ games | table; live games not available according to our data |
| Fortuna | ÚRHH | 5+ games | table; check live tables with the operator |
| Ice Casino | Curaçao | check with the operator | table and live |
| 22Bet | Curaçao Gaming Authority | check with the operator | table and live |
| Synottip | check at urhh.sk | 10+ games | check with the operator |
| Niké | check at urhh.sk | 20+ games | check with the operator |
| eTIPOS | check at urhh.sk | 5+ games | check with the operator |
Domestic ÚRHH-licensed operators are represented by Tipsport (details in our Tipsport Casino review) and Fortuna (see the Fortuna Casino review). If you also want live dealers, Ice Casino (Ice Casino review) and 22Bet (22Bet Casino review) offer both table and live roulette – but both operate under an offshore Curaçao licence, not under ÚRHH supervision. According to the available data, Niké has the largest roulette selection with more than 20 games, Synottip offers 10+ and eTIPOS 5+ titles.
Roulette rules
The roulette wheel has pockets numbered 1 to 36, alternating red and black, plus a green zero (two zeros in the American version). Before the spin you bet on a single number, a group of numbers, a colour, odd/even or low/high. Once the ball stops, the casino pays out the bets that cover the winning pocket.
Payouts are set as if the zero did not exist – a straight-up bet on one number pays 35:1, even though there are 37 or 38 pockets. The zero is the source of the house edge: with one zero it is 1/37, i.e. 2.70 %, with two zeros 2/38, i.e. 5.26 %.
| Variant | Zeros | Pockets | House edge | RTP | Special rules |
|---|---|---|---|---|---|
| European roulette | one (0) | 37 | 2.70 % | 97.30 % | none |
| French roulette | one (0) | 37 | 2.70 % | 97.30 % | La Partage / En Prison on even-money bets |
| American roulette | two (0 and 00) | 38 | 5.26 % | 94.74 % | none |
French roulette adds the La Partage and En Prison rules: if the zero comes up and you have an even-money bet (for example on red), you get half of your stake back, or the bet stays “in prison” for the next spin. On these bets the house edge is cut in half. American roulette is best avoided because of the double zero.

Online roulette: titles with the highest RTP
If you play single-zero rules, most titles have an RTP of 97.30 %. The difference lies more in the style of play – classic, live table or multipliers.
| Game | Provider | Type | RTP |
|---|---|---|---|
| Lightning Roulette | Evolution Gaming | live | 97.30 % |
| Red Door Roulette | Evolution Gaming | live | 97.30 % |
| Football Studio Roulette | Evolution Gaming | live | 97.30 % |
| European Roulette | NetEnt | European | 97.30 % |
| French Roulette | NetEnt | French | 97.30 % |
According to our data, Roulette (Habanero), Odds Up Roulette (Swintt), Casino Roulette (Pragmatic Play) and 500x Lucky Roulette (Belatra) also have an RTP of 97.3 %. Gravity Roulette (88 Mojo) lists 97.40 %, while Blazing Heat Roulette (Redstone) has only 96.15 %. Live tables and other dealer games are covered in our live casino guide.
Roulette strategies
Systems such as Martingale (doubling the stake after a loss) or D’Alembert (gradually raising and lowering the stake) are popular, but no system beats the house edge. Every spin is independent, and the maths of the variant does not change based on how you sequence your bets. Martingale also quickly runs into table limits and your budget – a losing streak can wipe out your bankroll. A strategy can help you with discipline at most, not with the outcome.
Watch out for bonuses too: roulette usually counts only 10–20 % towards bonus wagering, so clearing the terms on roulette takes much longer than on slots, which you will find in our guide to online slots. More on bonus terms in our casino bonuses guide.

Editorial opinion
Online roulette is one of the fairest casino games – if you choose the right variant. European and French roulette with an RTP of 97.30 % give players much better conditions than the American version with its double zero. With identical rules, the difference between titles from different providers is minimal; what matters more is whether you prefer fast RNG play or the atmosphere of a live table.
We recommend starting in demo mode, then playing with a fixed budget and not relying on any betting system. If you want a domestic licence, go for Tipsport or Fortuna; if you want a broader live offer, consider Ice Casino or 22Bet while keeping the offshore licence in mind.

FAQ
Which online roulette has the best RTP?
European and French roulette with a single zero have an RTP of 97.30 %, and French roulette further reduces the house edge on even-money bets thanks to the La Partage and En Prison rules. American roulette with a double zero has an RTP of only 94.74 %.
Can I play roulette online for free?
Yes, most casinos offer roulette in demo mode with virtual credit. Demo winnings cannot be withdrawn, but it is a good way to learn the rules and the interface without risk.
Is there a strategy that beats roulette?
No. Systems such as Martingale or D’Alembert only change the size of your stakes, not the probability of the outcome. The house edge stays at 2.70 % on European and 5.26 % on American roulette regardless of the system you use.
Does roulette count towards bonus wagering?
Usually only partly – typically 10–20 % of the stake, and some casinos exclude roulette from bonus terms entirely. Always check the exact percentage in the terms of the specific bonus.
