Understanding roulette odds is essential for informed betting and effective risk management. Whether playing on a mobile app or at the casino, every chip placement carries a fixed mathematical probability that directly affects potential returns.
What Are Roulette Odds?
Roulette odds describe the mathematical probability of a specific bet winning on a single spin, alongside the payout offered if it succeeds. Every bet on the table has fixed odds determined by how many numbers it covers and the wheel’s layout.

Roulette Payouts and Odds Table
Below is a consolidated table for Roulette Odds, the standard for most online casinos in 2026. Use this to verify the return on any specific chip placement.
| Bet Type | Numbers Covered | Payout | Probability (European wheel) | Probability (American wheel, with an extra 00) |
| Straight Up | 1 | 35 to 1 | 2.70% | 2.63% |
| Split | 2 | 17 to 1 | 5.40% | 5.26% |
| Street | 3 | 11 to 1 | 8.10% | 7.89% |
| Corner | 4 | 8 to 1 | 10.81% | 10.53% |
| Six Line | 6 | 5 to 1 | 16.20% | 15.79% |
| Column | 12 | 2 to 1 | 32.40% | 31.60% |
| Dozen | 12 | 2 to 1 | 32.40% | 31.60% |
| Even Money | 18 | 1 to 1 | 48.60% | 47.40% |
In European Roulette, the standard in Ireland, the wheel has 37 pockets (1–36 plus a single zero). At the same time, American Roulette adds a double zero, increasing the total to 38 pockets and raising the house edge.
The actual odds of hitting a single number are 36 to 1, but the payout is 35 to 1. This difference creates the house edge, which is 2.70% on European Roulette and 5.26% on American Roulette. Outside bets like Red/Black or Odd/Even offer higher win probabilities (48.6% on a European wheel) but lower payouts, while inside bets cover fewer numbers, pay more, and win less often.
While the payouts for a Straight Up bet remain 35 to 1 across most versions, the physical arrangement of the numbers can impact how you place your bets. For a visual breakdown of the single-zero setup, check out our guide to the European Roulette Wheel for Irish players.
The American wheel is a staple of many high-energy casino floors; its 38-pocket layout requires a different tactical mindset than its European counterpart. Discover the nuances of this variant in our American Roulette Wheel layout and strategy guide.
Roulette odds never change–each spin is independent, and no strategy can alter the underlying probabilities. Understanding roulette odds allows players to accurately assess risk, compare wheel types, and choose bets that align with their bankroll and tolerance for variance.
Inside Bet Odds
Inside bets are wagers placed on the inner section of the betting layout, directly on the numbers. These bets generally feature higher payout ratios but significantly lower probabilities of success. They are high-volatility wagers targeting a larger return from a single spin.
| Bet Type | How to Place It | Payout | European Probability | American Probability |
| Straight Up | Place a chip on a single number (e.g., 7). | 35 to 1 | 2.70% | 2.63% |
| Split | Place a chip on the line between two adjacent numbers. | 17 to 1 | 5.40% | 5.26% |
| Street (Three Line) | Place a chip on the outer edge of a row of three numbers. | 11 to 1 | 8.10% | 7.89% |
| Corner (Square) | Place a chip at the intersection where four numbers meet. | 8 to 1 | 10.81% | 10.53% |
| Six Line (Double Street) | Place a chip at the side intersection of two adjacent rows. | 5 to 1 | 16.20% | 15.79% |
Outside Bet Odds
Outside bets sit on the perimeter of the number grid. These bets cover larger groups of numbers, offering a higher probability of winning at roulette but with smaller payout ratios. Outside bets are often helpful in managing a bankroll over a longer period.
| Bet Type | How to Place It | Payout | European Probability | American Probability |
| Red or Black | Place a chip on the red or black diamond on the exterior. | 1 to 1 | 48.60% | 47.40% |
| Odd or Even | Place a chip on the “Odd” or “Even” box. | 1 to 1 | 48.60% | 47.40% |
| High or Low | Place a chip on “1-18” (Low) or “19-36” (High). | 1 to 1 | 48.60% | 47.40% |
| Dozen Bets | Place a chip on “1st 12”, “2nd 12”, or “3rd 12”. | 2 to 1 | 32.40% | 31.60% |
| Column Bets | Place a chip on the “2 to 1” box at the bottom of a column. | 2 to 1 | 32.40% | 31.60% |
Inside vs Outside Bets – How Do the Odds Differ?
The distinction between inside and outside bets is the primary decision regarding volatility.
- Volatility: Inside bets are high volatility (lower frequency of wins, higher payouts). Outside bets are low volatility (higher frequency of wins, lower payouts).
- Table Coverage: Outside bets cover large sections of the wheel (up to nearly 50%), whereas inside bets cover small, specific segments.
- Bankroll Impact: Betting purely on odds roulette inside numbers requires strict bankroll management to handle variance. Outside bets typically allow for extended play with a modest budget.
Selection depends on risk tolerance: seeking stability versus targeting higher multipliers.
How to Calculate Roulette Payouts
Calculating potential returns is straightforward. Multiply the stake by the payout odds, then add the original stake to determine the total return.
The formula is: (Bet Amount × Payout Ratio) + Original Bet = Total Return
Example 1: A Winning €10 Straight Up Bet
- Bet: €10 on Number 17.
- Payout: 35 to 1.
- Calculation: (€10 × 35) + €10 = €360.
- Net Return: €350.
Example 2: A Winning €20 Red Bet
- Bet: €20 on Red.
- Payout: 1 to 1.
- Calculation: (€20 × 1) + €20 = €40.
- Net Return: €20.
Understanding how to calculate roulette payouts clarifies whether a potential return justifies the risk associated with the odds of roulette. Always consider whether the potential return warrants the risk of losing the stake.
Live Roulette Variants, Odds and Payouts
In 2026, online casinos like Betmaster offer “Live Casino” games blending physical wheels with digital overlays (RNG multipliers).
Games such as Lightning Roulette or Quantum Roulette alter the standard roulette odds structure.
Lightning / Quantum Roulette
In these variants, standard Straight Up payouts are typically reduced (e.g., from 35:1 down to 29:1). In exchange, specific numbers receive multipliers ranging from 50x to 500x.
- Impact on Odds: The probability of hitting a number remains the same (1 in 37), but volatility increases. The standard payout is lower, while the maximum potential payout is higher.
- RTP: The Return to Player percentage usually remains similar to European Roulette (~97.3%), but the distribution of returns shifts heavily toward the multipliers.
Note that the reduced standard payout makes bankroll management more challenging when you don’t hit a multiplier. These games are designed for high-variance play.
Roulette Rules and How to Play
Understanding the flow of the game on modern casino apps is essential for placing bets correctly. A standard round follows a specific sequence.
- Place Your Bets: Select chips on the digital layout. This is the time to choose between roulette table odds ranging from single numbers to colour bets. On mobile, tap the chip value then the target area of the board.
- No More Bets: The dealer (or software) announces betting is closed. In live dealer games, a traffic light system often signals this.
- The Spin: The ball spins in the opposite direction of the wheel’s rotation.
- The Result: The ball lands in a numbered pocket. Winning bets pay out according to the paytable; losing bets are collected.
Knowing the sequence helps avoid “bet rejected” errors during live play.
Is It Possible to Improve Your Odds at Roulette?
Strictly speaking, players cannot change the roulette wheel odds or the physical probability of a number landing. The wheel has no memory; every spin is an independent event, and previous results do not influence future outcomes.
However, players can manage expected value and risk by making informed choices:
- Game Selection: Choose European or French Roulette over American Roulette to lower the house edge from 5.26% to 2.70% (or 1.35%).
- Bet Selection: Outside bets result in more frequent returns, reducing the speed of bankroll fluctuation.
- Bankroll Management: Set strict loss limits and deposit caps to ensure play remains within affordable boundaries.
Roulette Odds Recap: Lowest Risk Wagers
To minimise statistical risk while playing at Betmaster, prioritise bets with the lowest mathematical house edge.
- French Roulette Even Money Bets: (With La Partage) – 1.35% House Edge.
- European Roulette Even Money Bets: (Red/Black, High/Low) – 2.70% House Edge.
- European Roulette Dozens/Columns: – 2.70% House Edge with 32.4% probability.
Avoid the “Top Line” or “Basket Bet” in American Roulette (0, 00, 1, 2, 3), which carries a house edge of 7.89%. This is statistically the least favourable bet in roulette.
Roulette Strategies and Odds
Betting systems are methods for structuring stakes. While these strategies do not alter roulette odds, they provide a framework for betting.
- Martingale System: Doubling the stake after a loss on an even-money wager. The theory suggests that a single win recovers previous losses. The risk involves hitting table limits or exhausting funds during a losing streak.
- Fibonacci System: A progressive system based on the Fibonacci sequence. It is less aggressive than Martingale but still relies on eventually hitting a winning outcome.
- D’Alembert System: Increasing the stake by one unit after a loss and decreasing by one after a win. This is a lower-variance approach.
No strategy can overcome the house edge over time. Strategies are tools for bankroll management, not for altering the game’s mathematics.

FAQ
What are the best odds on roulette?
The best statistical odds are found on French Roulette tables that apply “La Partage” or “En Prison” rules. Here, the house edge on even-money bets is reduced to 1.35%. Without these rules, standard European Roulette even-money bets offer the next best value with a house edge of 2.70%. American Roulette carries a significantly higher house edge of 5.26%.
What is the €150 roulette strategy?
The €150 roulette strategy is a fixed betting pattern that covers a large portion of the table with €150. The typical setup involves:
- Betting €50 on the First Dozen (covers 1-12).
- Betting €50 on the Second Dozen (covers 13-24).
- Betting €5 on 10 specific Straight Up numbers in the Third Dozen (25-36). This leaves only a few numbers uncovered. While it covers roughly 90% of the wheel, a loss on the uncovered numbers results in the loss of the entire €150 stake.
Does roulette pay 35 to 1?
Yes, roulette pays 35 to 1 for a Straight Up bet. This wager is placed on a single, specific number. If that number lands, the payout is 35 units plus the original 1 unit stake. While this is the highest payout ratio on the table, it corresponds to the lowest probability of success (2.70% on a European wheel).
Is playing roulette worth it?
Playing roulette is a form of paid entertainment. The odds of roulette are transparent, allowing players to calculate risk accurately. If approached as entertainment with funds set aside strictly for that purpose, it is a standard casino option. Mathematically, the house retains an edge in the long term.
