If you’ve ever stood at a roulette table and noticed a single zero on one wheel and a double zero on another, you might have wondered how that small difference changes the game. The number of zero slots affects the odds on every bet and, over time, can noticeably alter how often you win relative to what you stake.
This article explains how the two wheel types differ, how the odds and payouts compare, and what that means for your choice of game. It aims to keep things clear and practical so you can judge which version suits your preferences.
Read on for a straightforward breakdown of the wheels, with examples that make the figures easy to picture.
What Are Double Zero and Single Zero Roulette?
Double zero and single zero roulette are the two main wheel types you will find in casinos and online. The essential difference is how many zero slots appear on the wheel.
Double zero roulette, often called American roulette, has both a 0 and a 00, creating 38 slots in total: numbers 1–36 plus 0 and 00. Single zero roulette, commonly labelled European or French roulette, has only one 0 and 37 slots overall. Both versions use the same basic bets and payouts, but that extra slot in double zero roulette changes the mathematical chances behind each wager.
Knowing this setup makes it easier to follow how odds and house edge change between the two, which is what we’ll look at next.
Key Differences Between Double Zero and Single Zero Wheels
Double zero and single zero wheels diverge in layout, the house advantage they give the operator, and where they tend to be offered. These differences affect how often winning bets occur and how the table feels to play on.
Table Layouts and Features
The most visible distinction is the presence of both 0 and 00 on the double zero table, while single zero tables display only one 0. That alters the number of total pockets and the arrangement on the betting grid: you’ll see spaces for 0 and 00 on the American-style layout, and a single 0 space on the European/French layout. French roulette sometimes includes additional rules such as La Partage or En Prison that can improve returns on even-money bets, but these are variants of the single zero format rather than separate wheel types.
The physical and visual differences also change how bets sit together on the layout, which some players prefer for clarity. That said, the core mechanics and payout ratios remain consistent across both wheel types.
A clear view of the layout leads naturally into where you are likely to encounter each version and how regulatory preferences influence availability.
Popularity in UK and International Casinos
Single zero wheels are the standard across the UK and Europe, and many online platforms offer them as the default. Double zero wheels are most common in the United States and appear less often in British and European venues. Online sites that target a wide audience may provide both variants, so checking the table type before you play is useful.
A key technical difference is the house edge: single zero roulette typically has a house edge of 2.70%, while double zero roulette’s edge is about 5.26%. That gap explains why many players favour single zero tables when they want the best statistical return on their wagers. Next, we’ll examine how these percentages translate into actual odds on popular bet types.
How Do the Odds Compare?
Odds change because the number of pockets affects the chance of the ball landing in any given place. Payouts stay the same, but the probability behind each payout differs between the two wheel types.
For a straight-up bet on a single number, single zero roulette gives 1 winning slot out of 37, while double zero gives 1 out of 38. Both pay 35:1 on a win, but the single zero wheel offers a marginally better chance that your number will hit. Even-money bets such as red/black or odd/even are slightly less favourable on the double zero wheel because the extra zero reduces the proportion of winning pockets.
Other bets scale similarly: a split covers two numbers, a street three, a corner four, and so on. As the number of covered pockets rises, the relative difference in probability between the two wheel types remains present but becomes less dramatic for each specific bet. Understanding these odds helps to set realistic expectations before you place chips, and leads neatly into how those odds pair with payout ratios.
Payout Structures Explained
Both wheel types use the same payout ratios for each bet, so the amounts you receive on a win are identical regardless of whether the wheel has one or two zeroes. What differs is how often those payouts occur because of the differing number of pockets.
Below is a clear comparison of common bet types and their payout ratios, shown with simple examples of returns on a £1 stake.
| Bet Type | Payout Ratio | Example (£1 bet) |
|---|---|---|
| Straight Up | 35:1 | £36 returned on a win |
| Split | 17:1 | £18 returned on a win |
| Street (Three) | 11:1 | £12 returned on a win |
| Corner (Four) | 8:1 | £9 returned on a win |
| Six Line (Six) | 5:1 | £6 returned on a win |
| Dozen/Column | 2:1 | £3 returned on a win |
| Red/Black, Odd/Even, High/Low | 1:1 | £2 returned on a win |
For example, a £5 straight-up win returns £180 (£5 × 35 plus the stake). The same payout applies in both wheel types; the single zero wheel simply gives a marginally higher chance of achieving that result because there is one fewer pocket.
With the payout table in mind, the next question many players ask is whether the jackpot potential differs between the two wheel types.
Is Jackpot Potential Higher with Double Zero or Single Zero?
In standard roulette, the largest single-spin payout comes from a straight-up number win, which pays 35:1 whether the wheel has one zero or two. The difference between wheel types affects only the probability of hitting that top payout, not the payout itself.
Some online roulette games offer separate progressive jackpots or special side-bet prizes triggered by specific combinations or rare spins. Those jackpots are features of the game provider and their rules, not of the base wheel type. In other words, choosing single or double zero does not change the headline jackpot values unless a particular version explicitly links a progressive prize to the base game.
Knowing that the top payout is fixed, regardless of wheel layout, helps when assessing whether a particular table or variant suits your aims. The final section offers a practical way to choose between the two styles.
Choosing the Right Roulette Game for You
The best choice depends on what you want from play. If you prefer the option that gives a slightly stronger mathematical return to the player, single zero roulette is typically the better fit because of its lower house edge. If variety, particular side bets, or regional styles appeal, double zero tables can add a different flavour to the session.
Consider stake levels and table rules as well: some single zero tables include variants like La Partage that further improve the return on even-money bets, while some double zero tables may offer side features or progressive pots that change the risk–reward balance. Think about how long you want to play, the size of the bets you prefer, and whether you value a marginally better edge or a different set of features.
Finally, set a clear budget and treat play as entertainment. If gambling starts to feel problematic, organisations such as GambleAware can offer advice and support.
This wraps up the key facts: the wheel with a single zero gives a modestly better chance on each bet, payouts remain the same across both wheels, and special jackpots depend on the game rules rather than the number of zeros. Choose the version that matches your preferences and play within limits for an enjoyable experience.
