How to Play Roulette: A 4-Step Guide
Roulette is a famously simple game to learn. Here is the basic flow of a round, whether you’re playing online or in a land-based casino.
- Choose Your Game: The most crucial first step is selecting the right table. As you can see from the table above, European and French roulette offer significantly better odds for the player than American roulette due to the single zero. Always choose a single-zero wheel when possible.
- Place Your Bets: You’ll be given time to place your chips on the betting layout. You can place chips on single numbers, groups of numbers, or outside propositions like Red or Black. The dealer (or software) will announce “no more bets” when the betting window closes.
- The Spin: The croupier spins the wheel in one direction and launches the small ball in the opposite direction. In online games, this is simulated by a Random Number Generator (RNG) or shown via a live video stream.
- The Result: The ball will eventually lose momentum and land in one of the numbered pockets. The croupier places a marker on the winning number, clears all losing bets from the table, and then pays out all winning bets.
Understanding Roulette Rules and the Table Layout
To use any betting system effectively, you must understand the board you’re playing on. The main differences come down to the wheel and the types of bets available.
The Wheel: American vs. European
The fundamental difference lies in the numbers on the wheel. A European wheel has 37 pockets: numbers 1-36 and a single green zero (0). An American wheel has 38 pockets: numbers 1-36, a single zero (0), and a double zero (00). That extra “00” pocket nearly doubles the house edge, making American roulette a far less favorable game for the player.
The Betting Layout: Inside vs. Outside Bets
All your betting options are laid out on the table felt and are broken into two main categories:
- Inside Bets: These are bets placed on the inner section of the number grid. They involve betting on a single number or a small group of adjacent numbers. Inside bets have high payouts but a low probability of winning.
- Outside Bets: These are bets placed on the boxes surrounding the main number grid. They cover large groups of numbers, such as Red/Black, Odd/Even, or an entire column. Outside bets have low payouts but a much higher probability of winning. Most betting systems are designed to be used with these even-money outside bets.
Special Rules: La Partage and En Prison
These player-friendly rules are found in French Roulette and apply only to even-money outside bets (Red/Black, Odd/Even, High/Low). If the ball lands on the green zero:
- La Partage: You immediately receive half of your bet back. This is simple and instantly cuts the house edge on these bets from 2.7% to 1.35%.
- En Prison: Your bet is “imprisoned” or locked in place for the next spin. If your bet wins on the next spin, you get your original stake back (without winnings). If it loses, the house takes it. This also cuts the house edge to 1.35%.
Bottom line: French Roulette with these rules offers the best odds you can find.
Roulette Betting Options, Odds, and Payouts
Here is a detailed breakdown of the various bets you can make, their payouts, and the winning probabilities on both European and American wheels.

| Odd/Even (Outside) | Bet on the winning number being either odd or even. | 1:1 | 48.6% | 47.4% |
| High/Low (1-18/19-36) (Outside) | Bet on the number being in the low or high range. | 1:1 | 48.6% | 47.4% |
| Dozens (Outside) | Bet on one of three dozens (1-12, 13-24, 25-36). | 2:1 | 32.4% | 31.6% |
| Columns (Outside) | Bet on one of the three vertical columns of numbers. | 2:1 | 32.4% | 31.6% |
| Straight Up (Inside) | Bet on a single number. | 35:1 | 2.7% | 2.6% |
| Split (Inside) | Bet on the line between two adjacent numbers. | 17:1 | 5.4% | 5.3% |

Popular Roulette Betting Systems Explained
IMPORTANT DISCLAIMER: No betting system can alter the game’s fixed odds or eliminate the house edge. The outcome of each spin is random and independent. These systems are for managing your betting pattern and bankroll, not for guaranteeing a profit.
-
The Martingale System
Concept: This is the most famous (and infamous) system. The idea is simple: you double your bet after every loss. When you eventually win, you recoup all previous losses plus a profit equal to your original stake. You then return to your starting bet.
- Pros: Very easy to understand. It provides a high probability of a small win in the short term.
- Cons: Extremely risky. A string of losses causes your bet size to increase exponentially, leading you to either hit the table limit or bankrupt your entire bankroll. This system can lead to catastrophic losses.
-
The Reverse Martingale (Paroli) System
Concept: As the name suggests, you do the opposite of the Martingale. You double your bet after every win. The goal is to capitalize on a winning streak. Typically, players will reset to their original bet after three consecutive wins or after any loss.
- Pros: Much less risky than the Martingale, as you are only increasing bets with the casino’s money. It protects your initial bankroll.
- Cons: A single loss can wipe out all the profit accumulated during a winning streak. It requires you to hit consecutive wins to see any real profit.
-
The D’Alembert System
Concept: A much flatter and safer progression system. You increase your bet by one unit after a loss and decrease it by one unit after a win. For example, if your unit is $5, you bet $5. If you lose, you bet $10. If you lose again, you bet $15. If you then win, you bet $10 again.
- Pros: Far safer for your bankroll than the Martingale. It’s a low-risk, slow-burn approach.
- Cons: Wins are slow and gradual. A long losing streak can still do significant damage, and it can take many wins to recover from a deep deficit.
-
The Fibonacci System
Concept: This system uses the famous Fibonacci sequence, where each number is the sum of the two preceding ones (1, 1, 2, 3, 5, 8, 13…). You progress to the next number in the sequence after a loss. After a win, you move back two numbers in the sequence.
- Pros: Less aggressive than the Martingale. It can withstand longer losing streaks before bets become unmanageably large.
- Cons: It’s more complex to keep track of. To make a profit, you still need your number of wins to be a significant fraction of your losses.
-
The James Bond Strategy ($150/$200 System)
Concept: This is a flat betting system, not a progressive one. The goal is to cover more than half the table on every spin. For a $200 total bet, you might place: $140 on the High numbers (19-36), $50 on the Six Line (13-18), and $10 on the single zero as insurance.
- Pros: Gives you a high probability (over 67%) of winning on any given spin.
- Cons: The loss, when it happens (if a number 1-12 hits), is substantial. It is a rigid system that doesn’t account for streaks.
The Truth About “99.4% Success Rate” Systems
You may see advertisements or videos online claiming a roulette system has a 99.4% success rate. These claims are deeply misleading and prey on a misunderstanding of probability. Here’s the reality:
- These systems are almost always a variation of the Martingale. They “succeed” by winning a tiny amount (e.g., your base unit) very frequently.
- The catastrophic “0.6% failure rate” is the inevitable losing streak that forces you to hit the table limit or run out of money.
- This single failure doesn’t just result in a small loss; it wipes out all of your previous winnings and a huge chunk of your bankroll.
- The math is simple: many small wins are eventually erased by one massive loss. The house edge always remains.
What is the Best Roulette Betting Strategy?
After reviewing all these systems, the answer to which one is “best” is nuanced.
The Safest Strategy
From a purely mathematical standpoint, the “safest” and best strategy is not a complex progression. It is simply to play on a French Roulette table that uses the La Partage or En Prison rule and only place even-money outside bets. This approach minimizes the house edge to its lowest possible point of 1.35%, giving you the best statistical chance of preserving your bankroll over time.
The Best Strategy for YOU
The “best” system for you is subjective and depends entirely on your goals and personality:
- Risk Tolerance: Are you a thrill-seeker who doesn’t mind big risks (Martingale)? Or do you prefer a conservative, low-volatility session (D’Alembert)?
- Bankroll Size: Aggressive progressions require a very large bankroll to withstand losing streaks. Flatter systems are better for smaller budgets.
- Enjoyment: Ultimately, the goal is entertainment. Choose a system that adds fun and structure to your game, rather than stress.

Common Mistakes to Avoid
Many players, new and old, fall into the same traps. Avoiding these will instantly improve your experience.
- The Gambler’s Fallacy: This is the belief that past results influence future outcomes. If the ball has landed on red 10 times in a row, the chance of it landing on black on the next spin is still exactly 48.6% (on a European wheel). The wheel has no memory.
- Chasing Losses: Abandoning your strategy and making increasingly large, emotional bets to try and win back money you’ve lost. This is the fastest way to deplete your bankroll.
- Ignoring the House Edge: Willfully choosing to play American roulette when a European or French table is available. You are giving the house a bigger advantage for no reason.
- Playing Without a Budget: Sitting down to play without a clear win/loss limit is a recipe for disaster. Always know when you’re going to walk away.
Bankroll Management 101
Proper bankroll management is more powerful than any betting system. Follow these simple rules to stay in control.
- Set a Session Budget: Before you start, decide on the maximum amount of money you are willing to lose. This should be discretionary income you can afford to part with.
- Define Your Betting Unit: A good rule of thumb is to make your base bet size 1-2% of your total session bankroll. If your budget is $200, your base unit should be $2-$4.
- Set Win/Loss Limits: Decide on a target profit (e.g., up 50%) and a hard stop-loss (e.g., down 100% of your budget). Stick to these limits no matter what.
- Cash Out Winnings: If you have a good run and double your initial stake, consider cashing out your original buy-in and playing only with the profits.
Playing Roulette on Mobile
The convenience of mobile play has transformed online gambling. Nearly all modern online casinos are fully optimized for mobile devices, either through a responsive website in your browser or a dedicated iOS/Android app. Top-tier software providers like Evolution Gaming and NetEnt design their live dealer and RNG roulette games with a mobile-first approach, ensuring the interface is intuitive and the gameplay is smooth on any screen size.
Frequently Asked Questions (FAQ)
Which is the best roulette betting system?
There is no single “best” system that guarantees wins. The best system depends on your personal risk tolerance and bankroll size. For the highest statistical return, the best strategy is to avoid complex systems and simply make even-money bets on a French Roulette table to take advantage of the 1.35% house edge.
What is the roulette system that actually works?
No roulette system “works” in the sense of guaranteeing a long-term profit. Roulette is a game of chance with a mathematical house edge that cannot be beaten. Systems are tools for managing your money and structuring your play, not for beating the casino’s built-in advantage.
What is the $150 roulette strategy?
This is typically a variation of the “James Bond” strategy. It’s a flat betting system designed to cover a large portion of the table on each spin. For example, on a $150 bet, you might place $105 on High (19-36), $40 on a Six Line (13-18), and $5 on zero for insurance. The goal is a high win-rate per spin, but the losses are significant when they occur.
What is the 1 3 2 6 system in roulette?
The 1-3-2-6 system is a positive progression system used on even-money bets. You start by betting 1 unit. If you win, your next bet is 3 units. If you win again, you bet 2 units. If you win a third time, you bet 6 units. If you complete all four wins, the cycle resets. If you lose at any stage, you immediately return to a 1-unit bet. It’s designed to capitalize on short winning streaks of up to four spins while limiting your risk to a maximum of two initial betting units.
Responsible Gambling Reminder: Roulette is a form of entertainment, not a source of income. Always play within your means, set limits, and never gamble with money you cannot afford to lose. If you feel you may have a gambling problem, please seek help from a professional organization.
