Which Is Better: Single Zero or Double Zero in Roulette?
Many people are curious about the differences between the single zero and double zero versions of roulette, but it is not always obvious what sets them apart or why it matters. If you have seen a roulette table online or on telly and wondered why some wheels have one zero while others have two, you are not alone.
This guide breaks down what makes these two types of roulette different, how they are played, and what to potentially keep in mind before having a go, especially if you are joining an online casino licensed by the UK Gambling Commission (UKGC). Read on to learn more.
What Is the Difference Between Single Zero and Double Zero Roulette?
Single zero and double zero roulette refer to the number of zero pockets on the wheel. In single zero roulette, often called European Roulette, the wheel has one green pocket marked with a 0. Double zero roulette, known as American Roulette, has two green pockets: 0 and 00. This is the most visible difference on the table.
The total number of pockets changes as a result. A single zero wheel has 37 pockets in total, numbered 1 to 36 plus the 0. A double zero version has 38 pockets, including the numbers 1 to 36, 0, and 00. That extra pocket shifts the probabilities for every bet.
Both versions use similar bet types, such as choosing a single number or betting on red or black. The payouts shown on the table may match, but because there are more pockets on a double zero wheel, the underlying chances are not the same.
Online versions can include small layout or rule differences, so it might be worth checking the on-screen rules for the table you choose.
If you do decide to try your hand at any type of roulette, remember to do so responsibly and within your means; never wager more than you can afford to lose.
House Edge Explained in Single Zero vs Double Zero Roulette
The term ‘house edge’ describes the built-in advantage the casino has over time. In roulette, how many zero pockets the wheel carries is the key factor.
On a single zero wheel, the house edge is about 2.7%. In practical terms, the casino expects to keep around £2.70 for every £100 staked over many spins. With just one zero, there are slightly better overall chances for most standard bets.
Double zero roulette is different. With two green pockets, the house edge rises to roughly 5.26%. Over time, that means the casino expects to retain about £5.26 from every £100 wagered. The additional 00 lowers the probability of each bet winning compared with a single zero wheel.
Some variants introduce rules that can adjust the house edge on specific bets, so the game information panel is always useful for the finer details. That difference in edge also explains why many players tend to favour single zero tables.
Why Is Single Zero Roulette Often Seen as the Better Choice?
Single zero roulette’s single 0 means there are 37 slots on the wheel rather than 38. That one-pocket difference reduces the casino’s statistical advantage and increases the combined chances of broader bets. For example, an even-money bet such as red or black gives a 48.6% chance of success on a single spin with a single zero wheel.
For many, that lower house edge makes the game feel more approachable. It does not change how the table is played, but it does change the long-term expectation, which is why regular players often prefer single zero versions.
Some single zero tables also include rules such as La Partage or En Prison on even-money bets. If the ball lands on 0, La Partage typically returns half of the stake, while En Prison usually holds the stake for the next spin. Both rules reduce the house edge on those specific bets compared with a standard single zero table.
Do Payouts Differ Between Single Zero and Double Zero Roulette?
Payouts are the amounts paid when a bet wins. In both single zero and double zero roulette, the posted payout ratios for standard bets are usually the same. A straight-up bet on one number, for example, typically pays 35 to 1 in both formats.
What changes is the probability behind those payouts. On a single zero wheel, there is one winning pocket out of 37. On a double zero wheel, it is one out of 38. The payout shown on the felt does not change, but the extra pocket makes that win slightly less likely on a double zero table.
Even-money bets such as red or black, odd or even, and high or low pay 1 to 1 across both versions. Again, the chance of success is marginally lower on a double zero wheel because of the 00. If a table offers extra side bets or features, their payouts and conditions will be listed in the paytable.
Where Can You Find Single Zero vs Double Zero Roulette Tables?
In the UK, single zero roulette is the most common format online and in land-based casinos. You will often see it listed as European Roulette or French Roulette, and most gaming lobbies label the wheel type clearly.
Double zero roulette, often called American Roulette, is less widespread in the UK but still appears at some venues and on select online platforms. Live dealer sections may offer both, depending on the game provider. The table layout makes it easy to spot whether 00 is present.
Availability and features can vary from site to site, so a quick look at the game information could help you see exactly what is in play. If you are playing online in Britain, choose a casino licensed by the UKGC for clear rules and player protections.
Should UK Players Choose Single Zero or Double Zero Roulette?
Players in the UK will encounter both single zero and double zero roulette, and the rules for placing bets are largely the same. The core difference is the extra 00 pocket on American-style wheels, which increases the house edge and slightly lowers the probability of winning any given bet.
Because of that, single zero tables are more popular and more common across British casinos. They offer the lower edge by default and sometimes add rules like La Partage or En Prison on even-money bets, which reduce it further. Double zero tables are still available if you want to experience that layout, and the game information will confirm everything from wheel type to any special rules.
There is no single right choice. If you prefer a lower house edge, single zero is the straightforward pick. If you are curious about how the American layout feels, double zero gives you that option. Either way, understanding the wheel and the rules could help you make informed decisions. Always remember to demonstrate responsible gambling practises.
