Roulette Odds – What Are The Odds On a Roulette Table?

Roulette is one of the most popular games in both online and land-based casinos. Understanding the odds might help you approach the game more thoughtfully. Each type of wager carries its own potential payout and chance of success, which affects how likely it is to appear.

Familiarising yourself with the basics allows you to play responsibly and make more informed choices if you decide to try the game. In this guide, we’ll cover the key aspects of roulette odds, including table odds, double-zero odds, bet types, how payouts function, and online roulette randomness.

Read on to gain a clearer understanding of roulette and how its odds influence play.

Is Roulette 50/50?

Many people wonder whether there are roulette bets that are almost guaranteed to win. Some options may seem close to this idea, but the reality is a little more complex.

The simplest bets involve choices such as colour or high and low numbers. These bets pay out even money if they are successful.

However, roulette wheels include an extra pocket—or, in some cases, two—that slightly alters the odds. On a standard European wheel, there is one such pocket, while an American wheel has two. If the ball lands in these pockets, even the most straightforward bets lose.

As a result, the odds for these bets are slightly lower than an even split. Later, we will look at the exact probabilities and explain how the type of wheel affects them.

It is also important to remember that each spin is independent. No previous outcome, pattern, or so-called “hot number” can guarantee a win.

What Are The Odds on a Roulette Wheel?

Roulette is played on two main types of wheel, each of which subtly affects the chances of winning.

The European wheel has 37 slots, numbered 1 to 36, plus a single extra pocket (the zero). The American wheel has 38 slots, adding a second extra pocket (the double zero) alongside the first.

The odds of winning depend on both the type of bet you place and which wheel you are using. Common bet types include:

• Straight Up: Betting on a single number.
• Split Bet: Betting on two numbers next to each other.
• Street Bet: Betting on three numbers in a row.
• Corner Bet: Betting on four numbers in a block.
• Six Line Bet: Betting on two adjacent rows of three numbers.

Bets that seem like even chances, such as choosing red or black, are slightly less likely to win because of the extra pocket(s). On a European wheel, the probability is just under 50%, and on an American wheel, it is slightly lower still.

Later, we will look at the exact odds and payouts for each type of bet.

It is also important to gamble responsibly. Only stake what you are prepared to lose and never chase losses.

Roulette Table Odds

Understanding table odds can help you decide how much to stake on different bets. Potential payouts vary depending on whether your wager covers a single number or a group of numbers.

Inside Bets:

• Straight Up: A bet on a single number, offering the largest potential payout.
• Split Bet: Covers two numbers; the potential payout is smaller but still significant.
• Street Bet: Covers three numbers in a row, with a moderate potential payout.
• Corner Bet: Covers four numbers in a block, with a lower potential payout.
• Six Line Bet: Covers six numbers across two rows, with the smallest potential payout among inside bets.

Outside Bets:

• Red/Black, Odd/Even, High/Low: Simple bets with potential payouts equal to your stake.
• Dozens and Columns: Cover 12 numbers each, with higher potential payouts than the basic outside bets.

It is important to remember that roulette is designed for entertainment. Always gamble responsibly and only stake what you are prepared to lose.

Double Zero Roulette Odds

Some roulette wheels include both a single extra pocket and a second one, which slightly reduces the chances of winning compared to the simpler single-zero wheel.

On a single-zero wheel with 37 slots:

• Red, Black, Odd, Even, High, or Low: 18 out of 37, or about 48.65%.
• Straight Up (single number): 1 out of 37, around 2.70%.
• Split Bet (two numbers): 2 out of 37, roughly 5.41%.
• Street Bet (three numbers): 3 out of 37, approximately 8.11%.
• Corner Bet (four numbers): 4 out of 37, about 10.81%.
• Six Line Bet (six numbers): 6 out of 37, around 16.22%.

On a double-zero wheel with 38 slots:

• Red, Black, Odd, Even, High, or Low: 18 out of 38, about 47.37%.
• Straight Up: 1 out of 38, roughly 2.63%.
• Split Bet: 2 out of 38, about 5.26%.
• Street Bet: 3 out of 38, around 7.89%.
• Corner Bet: 4 out of 38, approximately 10.53%.
• Six Line Bet: 6 out of 38, about 15.79%.

These figures show that the additional pocket slightly reduces the probability of success for every type of bet. While potential payouts remain the same, understanding this difference can be useful if you are playing on a double-zero wheel.

What Are The Best Roulette Bets?

There is no single “best” bet in roulette. The choice depends on your preferences and the balance you want between larger payouts and simpler wagers:

• High Payout Bets: These cover fewer numbers on the wheel. If they win, the rewards are substantial, but the chances of success are lower.
• Higher Probability Bets: These cover larger sections of the wheel. While the chances of winning are closer to even, they are still slightly reduced by the extra pocket(s).

It is important to take breaks and check that the game is staying within your personal limits. Always play responsibly and only wager what you are comfortable losing.

Is Online Roulette Truly Random?

Online roulette uses computer programmes called random number generators (RNGs) to determine the outcome of each spin. These systems are designed to ensure that every spin is independent, closely mimicking the randomness of a physical roulette wheel.

Reputable online casinos have their RNGs regularly tested by official authorities, helping to ensure that no result can be influenced by previous spins. Each spin is a separate event, and the numbers are generated without bias, just as they would be in a land-based casino.

How Do Roulette Payouts Work?

Potential roulette payouts vary depending on the type of bet you place. Here’s a guide to the most common bets and their potential returns:

Inside Bets:

• Straight Up: 35 to 1 – a single number; the potential payout is large because the chance of winning is low.
• Split Bet: 17 to 1 – covers two numbers; smaller than a straight-up win, but higher than most outside bets.
• Street Bet: 11 to 1 – covers three numbers in a row; offers a moderate potential payout.
• Corner Bet: 8 to 1 – covers four numbers in a block; a lower potential payout.
• Six Line Bet: 5 to 1 – covers six numbers; the smallest potential payout among inside bets.

Outside Bets:

• Red/Black, Odd/Even, High/Low: 1 to 1 – cover nearly half the wheel, though slightly less on wheels with extra pockets.
• Dozens and Columns: 2 to 1 – cover 12 numbers; the potential payout is higher than simple outside bets.

The exact probability of winning depends on both the type of bet and the wheel in use. For example, a straight-up bet on a single-zero wheel has a 1 in 37 chance (about 2.70%), while on a double-zero wheel it is 1 in 38 (around 2.63%). Even outside bets, which might appear to be an even split, are slightly affected by the extra pocket(s).

Understanding the potential payouts alongside the probabilities for each wheel type gives a clearer picture of what to expect from each bet.

Always gamble responsibly, stake only what you can afford to lose, and take breaks if you feel the game is affecting you. Support is available from organisations such as GamCare and GambleAware.
