Roulette has long been a staple of American casino floors, from the neon glow of the Las Vegas Strip to the historic boardwalks of Atlantic City. Among the many wagers available, the odd or even bet stands out as one of the simplest and most accessible options for players looking to ease into the game. This even‑money bet offers a near‑50% chance of winning on each spin, making it an attractive choice for both newcomers and seasoned gamblers who prefer a low‑volatility approach.
As online gambling continues to expand across the United States – with regulated markets now active in New Jersey, Pennsylvania, Michigan, and West Virginia – the ability to place a roulette odd or even bet online has never been more convenient. Whether you are spinning the wheel from your living room in Philadelphia or on a mobile device during a commute in Chicago, understanding the mechanics and nuances of this classic wager can help you make informed decisions and enjoy a more rewarding experience.
Understanding the Odd or Even Bet
The odd or even bet is one of the simplest wagers in roulette. You are betting that the next winning number will be either odd or even. In American roulette, numbers 1 through 36 are split evenly – 18 odd and 18 even – while the green 0 and 00 are neither odd nor even. This means that if you place a bet on odd, you win if the ball lands on any odd number (1, 3, 5, etc.) and lose if it lands on an even number or on either of the green zeros.
Because the bet covers 18 numbers out of 38 total slots on an American wheel, the probability of winning is 18/38, or approximately 47.37%. The payout is 1:1, meaning you double your money on a winning spin. This straightforward structure makes the odd or even bet a favorite among players who want to avoid the complexity of inside bets while still enjoying frequent action.
House Edge and Payout
Every bet in roulette carries a built‑in advantage for the casino, known as the house edge. For the odd or even bet on a standard American double‑zero wheel, the house edge is 5.26%. This figure comes from the fact that you have 18 winning outcomes and 20 losing outcomes (18 even numbers plus the two zeros). The 1:1 payout does not fully compensate for the extra losing slots, giving the casino its edge.
If you are playing European roulette, which uses a single zero, the odds improve slightly. With 18 odd numbers, 18 even numbers, and one green zero, the probability of winning becomes 18/37 (48.65%), and the house edge drops to 2.70%. Many online casinos in the United States now offer both American and European roulette variants, so checking the wheel type before placing your bet can make a meaningful difference in your long‑term expected return.
How to Place the Bet Online
Placing a roulette odd or even bet online is straightforward, whether you are using a desktop browser or a mobile app. After loading the roulette game, you will see a betting grid that includes sections for outside bets. Look for the boxes labeled “Odd” and “Even” typically located on the side or bottom of the layout. Simply click or tap the desired box, and your chip value will be applied.
Most online platforms allow you to adjust your bet size using a slider or preset chips. Once your wager is placed, confirm it and then click “Spin” to set the wheel in motion. Many US‑friendly casinos also offer live dealer roulette, where a real croupier spins the wheel in a studio streamed to your device. In that format, you place your odd or even bet using an on‑screen interface, and the dealer announces the result after each spin.
Strategies for Using Odd or Even
While roulette is ultimately a game of chance, some players employ betting systems that rely on even‑money bets like odd or even. The Martingale system, for example, involves doubling your bet after each loss, with the goal of recovering all previous losses plus a small profit when you eventually win. This approach can be exciting but requires a substantial bankroll and carries the risk of hitting table limits.
A more conservative strategy is to set a fixed percentage of your bankroll for each spin – say, 1% to 2% – and stick with odd or even bets exclusively. This method reduces volatility and allows you to enjoy extended play sessions. Keep in mind that no system can overcome the house edge in the long run, so treat any strategy as a way to manage your funds rather than a guaranteed path to profit.
Comparing Even‑Money Bets in Roulette
| Bet Type | Winning Numbers | Probability (American) | Payout | House Edge |
|---|---|---|---|---|
| Odd/Even | 18 numbers | 47.37% | 1:1 | 5.26% |
| Red/Black | 18 numbers | 47.37% | 1:1 | 5.26% |
| High/Low (1‑18 / 19‑36) | 18 numbers | 47.37% | 1:1 | 5.26% |
All three outside bets offer identical odds and payouts on an American wheel. The choice between them is purely a matter of personal preference. Some players feel superstitious about certain colors or number ranges, while others prefer the simplicity of odd or even. In European roulette, the house edge for all three bets drops to 2.70%, making them more favorable.
For example, some players prefer betting on red or black for its simplicity, while others enjoy the visual appeal of the high/low or odd/even sections.

| Wheel Type | Winning Probability (Odd/Even) | House Edge |
|---|---|---|
| American (double zero) | 47.37% | 5.26% |
| European (single zero) | 48.65% | 2.70% |
If you have the option, European roulette is generally the better choice for the roulette odd or even bet online, as it reduces the casino’s advantage by nearly half.
