The spinning wheel, the clatter of the ball, the sprawling green felt—the roulette table can seem intimidating at first glance. But behind its complex appearance lies a simple, elegant game of chance. This guide is designed to demystify the roulette table layout completely.

What is the Layout of a Roulette Table? A Visual Breakdown
The roulette table layout is comprised of two distinct, equally important parts: the wheel itself, where the outcome is decided, and the betting mat (or grid), where players place their wagers. Understanding how these two components work together is the key to mastering the game.
The Roulette Wheel: Single Zero vs. Double Zero
The iconic spinning wheel contains numbered pockets, ranging from 1 to 36, plus one or two green pockets. The key difference, and the most important factor for any player, is the number of green “zero” slots.
- European Roulette: Features 37 pockets in total, with numbers 1-36 and a single green ‘0’. This single zero gives the house a 2.7% edge.
- American Roulette: Features 38 pockets, with numbers 1-36, a single ‘0’, and a double ’00’. This extra green pocket almost doubles the house edge to a hefty 5.26%. For this reason, you should always choose European roulette when available.
The Betting Mat: Inside and Outside Bets
The large grid on the table is a map of all possible wagers. It’s neatly divided into two main categories: inside bets and outside bets.
Inside Bets (Higher Payouts, Lower Odds)
Inside bets are wagers placed directly on the numbers in the main grid. They offer high payouts but have a lower probability of winning.
- Straight Up: A bet on a single number. Place your chip entirely within one number square. Payout: 35 to 1.
- Split: A bet on two adjacent numbers. Place your chip on the line separating the two numbers. Payout: 17 to 1.
- Street: A bet on a horizontal row of three numbers. Place your chip on the outer edge of that row. Payout: 11 to 1.
- Corner (or Square): A bet on a block of four numbers. Place your chip on the intersecting corner of the four squares. Payout: 8 to 1.
- Six Line (or Double Street): A bet on two adjacent rows (six numbers total). Place your chip on the outer corner shared by the two rows. Payout: 5 to 1.
- Basket / Trio: A three-number bet involving the zero. In European roulette, this is 0,1,2 or 0,2,3. In American roulette, the “Basket” is a specific bet on 0, 00, and 2. Payout: 11 to 1.
Outside Bets (Lower Payouts, Higher Odds)
Outside bets are placed on the sections surrounding the main number grid. They cover large groups of numbers, offering lower payouts but a much higher chance of winning, making them ideal for beginners.
- Red or Black: A bet that the winning number will be either red or black. Payout: 1 to 1.
- Odd or Even: A bet that the winning number will be either odd or even. Payout: 1 to 1.
- High or Low: A bet on whether the number will fall in the low range (1-18) or the high range (19-36). Payout: 1 to 1.
- Dozens: A bet on one of three groups of 12 numbers: 1-12, 13-24, or 25-36. Payout: 2 to 1.
- Columns: A bet on one of the three vertical columns on the layout, each containing 12 numbers. Payout: 2 to 1.
How to Play a Round of Roulette: 5 Simple Steps
Once you understand the bets, playing the game is incredibly straightforward. Here’s how a typical round unfolds:
- Join a Table: Find a table that suits your budget and preferred style (we recommend European!). Exchange your cash for casino chips from the dealer.
- Place Your Bets: The dealer will announce, “Place your bets.” You now have a window of time to put your chips on the desired spots on the betting mat. You can place multiple bets on a single spin.
- The Spin: The dealer will spin the wheel in one direction and launch the small ball in the opposite direction. Shortly after, they will call out, “No more bets.”
- The Result: The ball will eventually lose momentum and land in one of the numbered pockets. The dealer places a marker, called a dolly, on the winning number on the layout.
- Payouts & Reset: The dealer sweeps away all losing bets and then pays out the winning wagers. Once all payouts are complete, the dolly is removed, and the next round begins.
Roulette Odds and Payouts
Understanding the relationship between payouts and the true odds of winning is crucial. Here is a clear breakdown for both European and American roulette variants.

| Street | 11 to 1 | 8.11% (1 in 12.3) | 7.89% (1 in 12.7) |
| Corner | 8 to 1 | 10.81% (1 in 9.25) | 10.53% (1 in 9.5) |
| Six Line | 5 to 1 | 16.22% (1 in 6.17) | 15.79% (1 in 6.33) |
| Dozen/Column | 2 to 1 | 32.43% (1 in 3.08) | 31.58% (1 in 3.17) |
| Red/Black | 1 to 1 | 48.65% (1 in 2.06) | 47.37% (1 in 2.11) |
| Odd/Even | 1 to 1 | 48.65% (1 in 2.06) | 47.37% (1 in 2.11) |
| High/Low | 1 to 1 | 48.65% (1 in 2.06) | 47.37% (1 in 2.11) |
Popular Roulette Betting Strategies
Crucial Disclaimer: No roulette strategy can ever guarantee a win or overcome the game’s inherent house edge. These are systems for managing your bets and bankroll, not for predicting a random outcome. Use them for fun and always play within your budget.
What is the $150 Roulette Strategy?
This is a high-coverage strategy designed to win on most numbers. It involves spreading $150 across the table for each spin:
- $100 on the High numbers (19-36).
- $40 on the first dozen (1-12).
- $10 on the 0 as an “insurance” bet.
With this setup, you win if the ball lands anywhere from 1-12 or 19-36. The only way to lose your entire stake is if a number between 13 and 18 hits. It’s a bold strategy but carries significant risk on every spin.
What is the 3/2 Rule in Roulette?
The 3/2 system is another combination bet that aims to cover roughly 70% of the wheel. It involves placing two separate outside bets in a 3:2 ratio.
- Place 3 units on an even-money bet like Red or Black.
- Place 2 units on a Column bet.
The key is to pair a color with a column that has more of the opposite color. For example, you could bet 3 units on Red and 2 units on the 2nd Column (which has 8 black numbers and 4 red numbers). This provides frequent, smaller wins but doesn’t protect against hitting the uncovered numbers or the zero.

Tips for Beginners
- Always Choose European or French Roulette: This is the single most important tip. The lower house edge gives you a mathematically better chance of winning over time.
- Play for Free First: Most online casinos offer demo or free-play versions of their roulette games. Use these to get comfortable with the layout, betting, and pace of the game without risking real money.
- Start with Outside Bets: Stick to simple, nearly 50/50 bets like Red/Black or Odd/Even. They provide frequent wins and help you build your confidence and extend your playing time.
- Understand the Odds: Before placing a chip, know the risk and potential reward. Don’t just bet on a “lucky number” without realizing it only has a 2.7% chance of hitting.
- Set a Budget and Stick to It: This is the golden rule of all gambling. Decide on a loss limit for your session *before* you start playing, and walk away if you reach it.
Common Mistakes to Avoid
- The Gambler’s Fallacy: Believing that past results influence future outcomes. If the ball landed on black five times in a row, the odds of it landing on red on the next spin are still exactly 48.65%. Each spin is an independent event.
- Chasing Losses: Increasing your bet size to try and win back money you’ve lost. This is the quickest way to deplete your bankroll and leads to poor decisions.
- Ignoring a Strategy’s Risk: Adopting a system like the Martingale (doubling your bet after every loss) without understanding that a short losing streak can wipe out your entire bankroll very quickly.
- Playing American Roulette: There is no strategic reason to choose the American version with its 5.26% house edge when a European table is available. You are simply giving the casino a bigger advantage.
Mobile Gaming Options
The convenience of modern online casinos means you can enjoy roulette anywhere. Top operators have fully optimized their websites for mobile browsers on both iOS and Android devices. Many also offer dedicated casino apps for an even smoother experience. Live Dealer roulette, with its HD video streams, works flawlessly on modern smartphones and tablets, bringing the thrill of a real casino right to your fingertips.

What is the 3/2 rule in roulette?
A: The 3/2 rule is a combination bet where you place 3 units on a color (like Red) and 2 units on a column that has a majority of the opposite color (like the 2nd column, which has 8 black numbers). It aims to cover around 70% of the numbers for frequent, smaller wins.
