When Should You Bet on Zero in Roulette? Odds, Payouts & Rules
If you’ve ever watched that little green zero settle on the roulette wheel, you’ll know how surprising and exciting it can be. But is betting on zero a smart choice, or simply a long shot?
Zero plays a special role. It shapes how the game works, affects payouts on several bets, and quietly influences your overall results.
This guide explains when betting on zero makes sense, the odds on different wheels, the payouts, and the table rules that matter, so you can decide if a chip on green fits your approach. Let’s start with the basics: the odds.
What Are the Odds of Zero on European Versus American Wheels?
The odds of the ball landing on zero depend on the wheel in use and the specific table rules. All outcomes are random, and probabilities apply to each individual spin.
On a European wheel, there is one green zero among 37 pockets. The chance of the ball landing on zero is 1 in 37, which is about 2.70%. This probability is the same on every spin and does not change based on previous results.
American wheels include both 0 and 00, bringing the total to 38 pockets. Each zero has a 1 in 38 chance of landing, while the combined chance of any zero (0 or 00) is 2 in 38, which is about 5.26%.
Because the American layout has two green pockets, the house edge is typically higher than on European tables. As a guide, European roulette generally carries a house edge of around 2.70%, whereas American roulette is usually around 5.26%. Certain European tables may offer rules such as La Partage or En Prison, which can reduce the effective edge on even‑money bets; always check the table rules before playing.
These figures are for information only and do not guarantee any outcome. Set limits, play within your means, and be aware that every spin is independent.
With the odds clear, the next question is simple: what can a winning zero bet pay?
How Much Does a Straight-Up Zero Bet Pay?
A straight-up bet on zero is a single-number wager placed directly on the green 0 on the layout. On double-zero (American) wheels, 0 and 00 are separate numbers, each requiring its own straight-up bet.
If zero lands, the standard single-number payout is 35 to 1. As an illustration, a £1 stake would return £35 in winnings plus your £1 stake, for £36 in total. Actual returns scale with your stake and are subject to the table’s minimums and maximums.
The chance of hitting zero depends on the wheel. On a single-zero (European) wheel with 37 numbers, the probability is 1 in 37 (about 2.70%). On a double-zero (American) wheel with 38 numbers, it is 1 in 38 (about 2.63%). The payout is the same, but the underlying odds differ.
Table rules can also change how zero affects other bets. For example, “La Partage” or “En Prison” rules may apply to even-money bets when zero hits, potentially reducing the amount lost on those wagers. Always check the specific table rules and displayed game information before you play.
Roulette is a game of chance and the house edge means you are expected to lose over time. Bet responsibly and only stake what you can afford to lose.
What Are the Table Rules That Affect Zero?
Certain European rules change what happens to even-money bets when zero appears. Even-money wagers include red/black, odd/even and 1–18/19–36, and zero sits outside these categories, so how it is treated depends on the table’s specific rules.
La Partage splits your even-money stake if zero lands, returning half to you and taking half. For example, a £10 red bet would see £5 returned and £5 collected by the house. This adjustment is applied immediately and only to qualifying even-money bets; it does not alter the outcome of other wager types.
En Prison holds your even-money stake for the next spin; if it wins on that spin, you recover the stake without additional profit. If the follow-up spin loses, or zero appears again (depending on the house rules), the held stake is forfeited. Both rules can reduce the house edge on even-money wagers on single-zero (European) wheels, often quoted around 1.35%, though the precise figure depends on the game configuration and how the rule is implemented.
American roulette typically does not offer these protections. There, even-money bets usually lose in full when zero or double zero comes in, contributing to a higher house edge on those wagers. Availability of any special handling for zero can vary by venue and game provider, so always review the on-table rules or help pages.
It’s worth checking the table rules before you start, as they can make a noticeable difference to your outcomes on red/black, odd/even and similar bets. Understanding the rules helps you know what to expect, but it does not change the randomness of results or guarantee returns—gambling should be done within your limits.
So when might you place a chip directly on zero itself?
When Might You Choose to Bet on Zero?
Some players include zero as part of broader coverage, especially when spreading wagers across several numbers or using neighbour-style patterns that focus on a section of the wheel. Depending on the table layout and game variant, neighbour bets may be offered as preset options or require manual placement, so check how your table handles them.
Zero can also be added to complement bets you already like. For example, if your layout mainly targets numbers near zero, a small straight-up chip can knit the selection together and slightly broaden your coverage in that area.
Keep in mind this does not improve the underlying odds or reduce the house edge. Outcomes are random, and no staking pattern or bet combination can guarantee profit over time.
On European wheels, the single green pocket means the probability for zero is marginally higher than on American tables with double zero. While the payout for a straight-up remains the same, the expected return is still negative in the long run, so any preference for one wheel over another should be based on understanding these differences rather than chasing results.
If you choose to add it, treat zero as one piece of a wider plan rather than a standalone shortcut to big returns. Set sensible limits, size stakes conservatively, and be prepared for variance—wins and losses can cluster. Only bet what you can afford to lose, and consider taking breaks if play stops being enjoyable.
How Does Betting on Zero Compare With Other Bets in Expected Return?
A straight-up bet on zero has the same long‑term expectation as any other single number. It pays 35:1 on a standard wheel, but it lands rarely, so its theoretical return is identical to a straight‑up on, say, 17 or 32.
On European wheels (37 pockets), the house edge is about 2.70% across standard bets, which corresponds to an RTP of roughly 97.30% calculated over a very large number of spins. On American wheels (38 pockets), the extra green pocket lifts the house edge to around 5.26% (RTP about 94.74%). These figures are theoretical; short‑term results can and do vary.
Even‑money bets like red/black or odd/even win more frequently but pay less; the edge remains the same because zero (and double zero in America) tilts the maths in the casino’s favour. In some European games with French rules such as la partage or en prison, the edge on even‑money bets can be reduced when zero appears, but this does not change the edge on straight‑up numbers.
So zero offers the same expected return as any other number, but with the higher‑variance profile that comes with single‑number bets. This means outcomes will be more volatile, with longer losing streaks and occasional larger wins.
No staking method can remove the house edge, and all outcomes are random. Bet responsibly, set limits, and only stake money you can afford to lose.
Zero Bet Variations and Call Bets
Roulette offers several bets that include zero within a wider section of the wheel, which can be a neat way to cover nearby outcomes without placing lots of separate chips.
These are often presented as announced or call bets and may be shown on a racetrack layout. They add convenience but do not change the underlying odds or the house edge, and availability can vary between casinos and online tables.
Zero Spiel, sometimes called Zero Game, targets zero and the numbers immediately around it on the wheel, typically including 12, 35, 3, 26, 32 and 15. It uses multiple chips and pays in different ways depending on which covered number hits.
Exact compositions and chip counts can differ by venue or wheel style (single‑zero or double‑zero). Stakes are usually placed as a set, with each position following standard roulette payouts for straights, splits or corners. Always check how many chips are involved and whether table minimums apply per chip or per announced set.
You might also see call bets such as Voisins du Zéro (Neighbours of Zero), which cover a larger arc wrapped around zero. These require several chips because they are built from combinations of splits, streets and corners, giving you broader coverage in one announcement to the dealer.
Other common announced bets may be offered alongside Voisins, and some tables provide one‑click templates online. However, rules and chip patterns are not universal, so confirm the layout, total stake and how wins are settled before you place the bet.
If you use these options, check the exact layout and total stake so you are clear on what you are committing to and what each hit could return. Returns are determined by the individual bet types within the set, and no configuration removes the house edge or guarantees a profit.
Keep control of your play: set a budget, avoid chasing losses and take breaks. If announced bets are permitted, the dealer should confirm the wager; if not, you will need to place chips manually. Only gamble with money you can afford to lose and consider setting deposit and time limits where available.
Practical Examples: Payouts, Wagers and Expected Return
A £2 straight-up bet on zero pays 35:1 if it wins. That means you would receive £70 in winnings plus the return of your £2 stake, for £72 in total.
However, most spins will not land on your chosen number. On a European wheel there are 37 pockets, so the chance of hitting zero with a single number bet is 1 in 37. If the spin misses, you lose the £2 stake for that round.
Covering every number on a European wheel with £1 each, including zero, costs £37. If any single number hits, that one position returns £36 in total (your £1 stake on that number plus £35 in winnings). You would still be down £1 overall on that spin.
This example shows how the house edge is built into the pay table. It applies no matter which number lands, including zero, and it is not a way to guarantee a profit. While covering more numbers can reduce volatility, the expected loss per spin remains.
For any single-number bet on a European table, the long-run expectation is the same: the casino retains roughly 2.70% of the total amount staked over time (an approximate 97.30% return to player). Zero does not change that; it simply offers a high payout when it appears.
Outcomes are random and independent, and short-term results can vary significantly from the long-run average. Never stake more than you can afford to lose, and consider setting limits to help you stay in control.
What Are Common Misconceptions About Betting on Zero?
One persistent idea is that zero becomes more likely after a long gap. In reality, each spin is independent, so past results do not change the probability on the next one. Streaks and dry spells happen by chance, and both physical wheels and certified RNG games are designed so that previous outcomes do not influence future ones.
Another misconception is that zero carries a different chance of winning than other single numbers. It does not. On a single-zero wheel every number, including zero, has the same probability per spin, and the straight-up payout is the same regardless of which number you choose; the same principle applies on double-zero wheels, just with a different overall probability across 38 pockets.
Some believe that focusing on zero can beat the house edge. There is no special strategy that turns the maths around, and systems such as doubling after losses simply increase risk without changing the expected return. Zero is also neither red nor black and is not odd or even, which is why it contributes to the house edge on even‑money bets unless specific rules (such as La Partage or En Prison) apply at that table.
Clear information is the best advantage. Check which wheel and rules are in use, read the game rules and any table limits, and make sure you understand how payouts work before you place a bet. No system guarantees a profit, and outcomes are always uncertain.
Gamble responsibly: set a budget and time limits, avoid chasing losses, and only play with money you can afford to lose. If you feel your play is no longer fun or is causing harm, consider using safer gambling tools such as deposit limits, time‑outs or self‑exclusion, and seek support if needed. 18+ only.
