Roulette is a classic casino game that combines chance with strategy, attracting players with its simple yet sophisticated betting system. The allure of the roulette wheel stems from the variety of bets players can make, each with its own odds and potential payouts. Understanding the probability of each type of wager is crucial for players who aim to make informed decisions and manage their bankrolls effectively.
The odds in roulette are influenced by the type of wheel in use. The American version, with its additional double zero pocket, offers different probabilities compared to the European version, which has a single zero. Each bet, from a straight-up bet on one number to an outside bet on red or black, has mathematically defined odds that correspond to their payouts. The payouts typically reflect the risk, with higher payouts associated with less likely outcomes.
Knowledge of these odds and payouts helps players navigate the game, whether they are newcomers to the roulette table or seasoned gamblers. This understanding allows for more strategic bets, balancing risk with the potential for significant rewards. Moreover, a thorough grasp of roulette mechanics empowers players to enjoy the game while managing their expectations and bankrolls.
Basics of Roulette
Roulette is a casino game named after the French word meaning little wheel. The game's rules and betting options are primarily centered around the roulette wheel layout and the types of bets one can place.
Roulette wheel layout
The roulette wheel layout varies depending on whether it is the American or European version. The American wheel has 38 pockets: numbers 1 to 36, 0, and 00. The numbers are alternately colored red and black, while the 0 and 00 are green. In contrast, the European wheel has 37 pockets with numbers 1 to 36 and a single 0, also omitting the double zero altogether, which affects the odds.
Types of bets
Roulette offers two main types of bets: inside bets and outside bets.
- Inside Bets:
- Straight Up: A bet on a single number.
- Split: A bet on two adjacent numbers.
- Street: A bet on three consecutive numbers on the same line.
- Corner (or Square): A bet on four numbers that meet at one corner.
- Six Line (or Double Street): A bet on six consecutive numbers that form two horizontal lines.
| Bet Type | Numbers Covered | Payout Ratio |

These outside bets have a probability of 48.65% on a European wheel and 47.37% on an American wheel due to the extra double zero.
Dozens and columns:
Players who bet on one of the three dozens or columns can expect a winning probability of 32.43% on European and 31.58% on American roulette.
Odds for inside bets
Straight-up (a single number):
The odds of hitting a single number are 2.70% on a European roulette wheel and 2.63% on an American wheel.

Roulette payouts
Roulette payouts vary significantly based on the type of bet placed. Players can better strategize their bets by understanding the specific payouts for each.
Payouts for outside bets
Even/Odd: A bet on all even or odd numbers pays 1:1. Red/Black: Wagering on either all red or all black numbers also pays 1:1. High/Low: Betting on either 1-18 (low) or 19-36 (high) numbers yields a 1:1 payout. Dozens: Placing bets on one of the three dozens (1-12, 13-24, 25-36) offers a payout of 2:1. Columns: Similar to dozens, betting on one of the three columns on the roulette table grants a 2:1 payout.
Payouts for inside bets
Straight Up: Betting on any single number provides a payout of 35:1. Split: A bet on two adjoining numbers, either vertically or horizontally, offers a payout of 17:1. Street: Wagering on any three numbers in a horizontal line grants an 11:1 payout. Corner: A corner or square bet, placed on the corner of four numbers, pays out 8:1. Six Line: A bet covering two adjacent lines (six numbers in total) yields a 5:1 payout. Basket: This bet, specific to American roulette on the first five numbers (0, 00, 1, 2, 3), offers a payout of 6:1.
Strategies for betting
Roulette betting strategies are traditionally classified as either conservative or aggressive, each with specific tactics designed to capitalize on the game’s odds.
Conservative strategies
Conservative strategies prioritize sustaining the bankroll and playing for a longer duration. One example is the Martingale System, where a player doubles their bet after each loss, assuming a win will recover all previous losses and gain a profit equal to the original bet. This method is depicted in the following table:
| Spin | Bet amount | Outcome | Cumulative loss | Next bet |
|---|---|---|---|---|
| 1 | $1 | Loss | $1 | $2 |
| 2 | $2 | Loss | $3 | $4 |
| 3 | $4 | Win | $0 | $1 |
Another conservative approach is the D’Alembert system, which involves increasing the bet by one unit after a loss, and decreasing by one unit after a win. The progression is slower, aiming to minimize losses over time.
Aggressive strategies
Aggressive strategies aim for significant wins in a short period. They carry higher risks but also the potential for higher rewards. An example of an aggressive strategy is the Fibonacci system, which follows a sequence where each number is the sum of the two preceding ones. The betting pattern looks as follows:
- Start with a single unit bet.
- Follow the sequence (1, 1, 2, 3, 5, 8, etc.), moving one step forward in a loss and two steps back following a win.
Another aggressive tactic is betting on a Single number. The odds of hitting a single number are 35 to 1, which means that winning can yield a substantial payout but the chances of winning are low. This method involves picking a number and continuously betting on it for a set number of spins or until it wins.

Roulette variations and odds
Roulette comes in three popular variations: American, European, and French. Each offers different odds to the player due to unique rules and wheel layouts.
American roulette odds
American Roulette features a wheel with 38 pockets: numbers 1 to 36, a zero (0), and a double zero (00). This additional double zero increases the house edge to 5.26%. Here are the odds and payouts for American Roulette:

European roulette odds
European roulette has 37 pockets with a single zero (0) and numbers 1 to 36. The absence of the double zero pocket reduces the house edge to 2.70%. Here are the odds and payouts for European Roulette:
- Single number: 35 to 1 payout with a 2.70% chance of winning.

French roulette odds
French roulette resembles European roulette in terms of the single-zero wheel layout, offering the same odds. However, French Roulette introduces rules like ‘La Partage' and ‘En Prison' that can reduce the house edge on even-money bets to 1.35%. Here are the odds and payouts for French Roulette, without considering the additional rules:
- Single number: 35 to 1 payout with a 2.70% chance of winning.
- Split (two numbers): 17 to 1 payout with a 5.41% chance of winning.
- Street (three numbers): 11 to 1 payout with an 8.11% chance of winning.
- Corner (four numbers): 8 to 1 payout with a 10.81% chance of winning.
- Six line (six numbers): 5 to 1 payout with a 16.22% chance of winning.
- Column/Dozen: 2 to 1 payout with a 32.43% chance of winning.
- Even/Odd, Red/Black, High/Low: 1 to 1 payout with a 48.65% chance of winning.
Tips for maximizing winnings
When approaching roulette, players should focus on making informed decisions and understanding the game's structure. One strategic move is to select bets with the best odds. For instance, even-money bets such as Red/Black, Odd/Even, and High/Low offer higher probabilities of winning, with odds standing at nearly 50%.
Players may also manage their bankrolls efficiently by setting clear limits and adhering to them. This involves deciding on a fixed amount for each session and not exceeding it, which helps in sustaining play over the long term.
Utilizing betting systems wisely can be beneficial. The Martingale system, for example, suggests doubling the bet after a loss. Nonetheless, players should exercise caution as such strategies do not alter the house edge and may require substantial bankrolls.
Below is a quick reference for comparing bet types and their respective payouts:
| Bet Type | Payout | Odds of Winning (European Roulette) |
|---|---|---|
| Single Number | 35:1 | 2.7% |
| Split | 17:1 | 5.4% |
| Street | 11:1 | 8.1% |
| Corner | 8:1 | 10.8% |
| Six Line | 5:1 | 16.2% |
| Column/Dozen | 2:1 | 32.4% |
| Even-Money Bet | 1:1 | 48.6% |
Understanding the table layout and betting options can also aid in making prudent decisions. A player must be familiar with the different betting areas and the odds associated with each.
Lastly, players should resist the temptation to “chase losses”. One should accept losses as part of the game and know when to walk away. This approach avoids rash decisions and potentially larger losses.
