Outside bets represent the most accessible entry point for roulette players in the United States. Unlike the higher-risk inside bets that target single numbers, outside bets cover larger sections of the wheel and offer nearly 50% winning chances on even-money wagers. For players at casinos from Las Vegas to Atlantic City, understanding how to structure an outside bet strategy can transform a casual spin into a disciplined approach to the game. The key lies not in chasing improbable jackpots but in leveraging the math behind the felt.
American roulette features a double-zero wheel, which gives the house a 5.26% edge on all outside bets except the five-number bet. That edge is higher than the 2.70% found in European roulette, but outside bets remain the most favorable option for players who want to extend their session time and reduce volatility. By focusing on red or black, odd or even, or high or low numbers, you engage with the core probabilities of the game rather than the long-shot allure of a single number.
Understanding Outside Bets in American Roulette
Outside bets are placed on the outer sections of the roulette layout. They include red or black, odd or even, 1-18 or 19-36, and the dozen and column bets. Each of these wagers covers multiple numbers, which increases your chance of winning on any given spin. In American roulette, the even-money outside bets (red/black, odd/even, high/low) pay 1 to 1 and have 18 winning numbers out of 38 total slots. The two green zeros tilt the odds slightly in the house’s favor, but the payout remains fair for the risk.
Dozens and columns pay 2 to 1 and cover 12 numbers each. While they offer a higher payout, the probability of winning drops to 12 out of 38, or roughly 31.6%. For US players, the distinction matters because many land-based casinos in Nevada and New Jersey offer both American and European roulette tables. Choosing a single-zero table when available can improve your expected return, but outside bet strategies are designed to work within the American game’s parameters.
Why Outside Bets Appeal to US Casino Players
The appeal of outside bets runs deep in the US casino culture. In Las Vegas, first-time visitors often gravitate toward the even-money wagers because they are easy to understand and provide frequent small wins. Atlantic City regulars know that outside bets allow for longer sessions without the dramatic swings of straight-up bets. Online casinos licensed in Pennsylvania, Michigan, and New Jersey also see high engagement on outside bets, as players appreciate the lower volatility when playing from home.
Another factor is the social aspect. At a crowded roulette table, watching the ball land on red after you bet on red creates a shared moment of excitement. Outside bets keep the action flowing without the isolation of a single-number wager. For the casino brand, promoting outside bet strategy aligns with responsible gaming principles – players who understand the math are less likely to chase losses with reckless inside bets.
The Martingale System: Doubling Down on Even-Money Bets
The Martingale is the most famous outside bet strategy in the United States. The concept is simple: after every loss on an even-money bet, double your wager. When you eventually win, you recover all previous losses plus a profit equal to your original bet. For example, start with $10 on red. If you lose, bet $20 on red. Lose again, bet $40, and so on until red hits.
The strategy works in theory, but it requires a substantial bankroll and a table with a high maximum bet limit. In US casinos, minimum and maximum limits vary widely. A $10 minimum table might have a $500 maximum, limiting you to only six consecutive losses before you cannot double again. The risk of hitting that limit or simply running out of money makes the Martingale a high-stakes approach despite its surface-level simplicity. Many experienced players use a modified version that resets after a win instead of continuing the progression.
The Reverse Martingale: Letting Your Wins Ride
Also known as the Paroli system, the reverse Martingale flips the logic. Instead of increasing bets after losses, you increase after wins. The goal is to capitalize on winning streaks while limiting losses during cold spells. Start with a base bet, say $10 on black. If you win, bet $20 on the next spin. Win again, bet $40. After three consecutive wins, take your profit and reset to the base bet.
This strategy appeals to US players who prefer a more conservative risk profile. You never chase losses, and your downside is limited to the base bet on any losing streak. The downside is that a single loss after a win resets the progression, so you need multiple consecutive wins to see significant gains. The reverse Martingale works well at tables with low minimums, allowing you to ride short hot streaks without overexposing your bankroll.
The D’Alembert Strategy: A Balanced Approach
The D’Alembert system offers a middle ground between the aggressive Martingale and the cautious reverse Martingale. After a loss, you increase your bet by one unit. After a win, you decrease it by one unit. The idea is that wins and losses will eventually balance out, and you will profit from the net difference. For example, start with $10. Lose, bet $11. Lose again, bet $12. Win, bet $11. Win, bet $10.
Conversely, after a win you reduce your bet by one unit. This creates a more gradual progression that avoids the extreme swings of other systems. The appeal lies in its middle ground approach, balancing risk and reward for steady play.
This strategy is popular among US players who find the Martingale too risky but want more structure than flat betting. The D’Alembert works best on even-money outside bets and requires a modest bankroll. It does not protect against long losing streaks, but it slows the rate of loss compared to doubling systems. Many Atlantic City regulars use a variant that adds two units after a loss and subtracts one after a win, known as the “modified D’Alembert.”
Comparing Outside Bet Types and Their Odds
The following table shows the standard outside bets available on an American roulette wheel, along with their payouts, winning probabilities, and house edge.
| Bet Type | Payout | Winning Numbers | Probability | House Edge |
|---|---|---|---|---|
| Red or Black | 1:1 | 18 | 18/38 (47.37%) | 5.26% |
| Odd or Even | 1:1 | 18 | 18/38 (47.37%) | 5.26% |
| 1-18 or 19-36 | 1:1 | 18 | 18/38 (47.37%) | 5.26% |
| Dozen (1-12, 13-24, 25-36) | 2:1 | 12 | 12/38 (31.58%) | 5.26% |
| Column | 2:1 | 12 | 12/38 (31.58%) | 5.26% |
All outside bets carry the same house edge in American roulette, making them equally fair from a mathematical standpoint. The choice between them comes down to personal preference and the betting progression you intend to use.

| Strategy | Bet Change After Loss | Bet Change After Win | Risk Level | Bankroll Needed |

| D’Alembert | Increase by 1 unit | Decrease by 1 unit | Medium | Moderate |
Each strategy has its advocates. The Martingale appeals to players who believe a win is inevitable. The reverse Martingale suits those who want to capitalize on runs. The D’Alembert offers a steady progression that feels less extreme. No system changes the house edge, but they can help you manage your session and avoid impulsive decisions.
Practical Recommendations for Outside Betting
- Set a session bankroll and stick to it. Decide how much you are willing to lose before you sit down at the table.
- Choose tables with low minimums and high maximums to give your betting progression more room to work.
- Use even-money outside bets only for progression systems. Dozens and columns have lower win rates and can drain your bankroll faster.
- Take a break after a significant win. Lock in your profit and reset your mental focus before continuing.
- Avoid the five-number bet (0, 00, 1, 2, 3) in American roulette. It carries a 7.89% house edge, the worst on the table.
- Practice any new strategy in free play or low-stakes online games before risking real money.
- Remember that no strategy overcomes the house edge in the long run. Treat outside betting as entertainment, not a guaranteed income.
