Every roulette bet you’ll ever make lives somewhere on the betting grid. That green felt rectangle, crammed with numbers and lines and labeled boxes, is the entire universe of your options — from a $5 longshot on a single number to a $100 grind on red. The problem is that most players treat it like a slot machine: pick a spot, drop a chip, hope for the best.

The grid deserves better than that. Each zone on it carries a specific probability, a specific payout, and a specific cost over time. This guide breaks down every bet type on the roulette betting grid, what it actually pays, and where the house takes its cut.

Understanding the Roulette Betting Grid

The roulette betting grid is the layout printed on the table cloth that shows the numbers 1 through 36 arranged in three columns and twelve rows, plus the zero(s) positioned separately. It’s the physical interface where players place chips to make their bets.

The Layout: Inside and Outside the Grid

  • Inside bets are wagers placed directly on specific numbers or small groups of numbers inside the numbered grid.
  • Outside bets are made on larger groups or categories of numbers located on the edges of the grid.

Here’s a quick snapshot:

Bet Type Location on Grid Risk Level Typical Payout
Straight Up Single number square Highest risk 35:1
Split Line between two numbers High risk 17:1
Street Row of three numbers Medium-high risk 11:1
Corner (Square) Four numbers in a square Medium-high risk 8:1
Six Line Two adjacent rows (6 numbers) Medium risk 5:1
Column One of three columns on outside Medium-low risk 2:1
Dozen 1–12, 13–24, 25–36 outside rows Medium-low risk 2:1
Red/Black Edge area below numbers Lowest risk 1:1
Even/Odd Edge area below numbers Lowest risk 1:1
Low/High Edge area below numbers Lowest risk 1:1

The Zero(s)

  • European roulette has a single zero (0) at the top of the grid.
  • American roulette includes both 0 and 00.
  • French roulette uses the single zero like European but often includes the La Partage rule, which impacts payouts on even-money bets.

The zero(s) are critical because they affect your winning chances and house edge. Take the case of a $500 session: the presence of 00 in American roulette raises the house edge from 2.70% in European to 5.26%. This means that over the long run, for every $100 wagered, you lose about $2.70 on a European wheel but $5.26 on an American wheel, which is almost double.

Inside Bets: High Risk, High Reward

Inside bets are wagers placed on the numbered squares themselves or the lines between them. These bets offer higher payouts but come with lower probabilities of winning.

1. Straight Up (Single Number)

  • How to place: Chip directly on any single number.
  • Payout: 35 to 1.
  • Probability:
    • European/French: 1/37 ≈ 2.70%
    • American: 1/38 ≈ 2.63%

At a $10 minimum table, betting $10 on number 17 in European roulette. If it hits, you receive $350 in winnings plus your $10 stake back, totaling $360. The chance of winning this bet is about 2.7%, which means statistically you can expect to hit this number once every 37 spins on average.

2. Split Bet (Two Numbers)

  • How to place: Chip on the line between two adjacent numbers.
  • Payout: 17 to 1.
  • Probability:
    • European/French: 2/37 ≈ 5.41%
    • American: 2/38 ≈ 5.26%

A player with a $300 bankroll who places a $20 split bet on 17 and 20. This pays $340 plus the original $20 if either hits. This bet roughly doubles your chance to win compared to a straight-up bet but halves the payout.

3. Street Bet (Row of Three Numbers)

  • How to place: Chip at the outer edge of a row, covering three numbers.
  • Payout: 11 to 1.
  • Probability:
    • European/French: 3/37 ≈ 8.11%
    • American: 3/38 ≈ 7.89%

Here's the scenario: Betting $15 on the street covering 16, 17, and 18 in European roulette. If the ball lands on any of these, you win $165 plus your $15 back.

4. Corner Bet (Square of Four Numbers)

  • How to place: Chip at the intersection point where four numbers meet.
  • Payout: 8 to 1.
  • Probability:
    • European/French: 4/37 ≈ 10.81%
    • American: 4/38 ≈ 10.53%

5. Six Line Bet (Double Street)

  • How to place: Chip on the line at the end of two adjacent rows, covering six numbers.
  • Payout: 5 to 1.
  • Probability:
    • European/French: 6/37 ≈ 16.22%
    • American: 6/38 ≈ 15.79%

Outside Bets: Lower Risk, Smaller Payouts

Outside bets cover larger groups of numbers and have higher probabilities of winning but lower payouts. They are often the safest bets for players who want steady returns.

1. Column Bets

  • How to place: Chip on one of the three boxes labeled “2 to 1” at the bottom or side of the grid.
  • Coverage: 12 numbers each.
  • Payout: 2 to 1.
  • Probability:
    • European/French: 12/37 ≈ 32.43%
    • American: 12/38 ≈ 31.58%

Running the numbers: Placing a $30 bet on the second column in European roulette means you cover 12 numbers. The chance of winning is roughly one in three, and if successful, you win $60 plus your original $30 back.

2. Dozen Bets

  • How to place: Chip on “1st 12,” “2nd 12,” or “3rd 12.”
  • Coverage: Numbers 1–12, 13–24, or 25–36.
  • Payout: 2 to 1.
  • Probability: Same as column bets.

3. Even-Money Bets

  • These include:

    • Red or Black
    • Odd or Even
    • 1 to 18 (Low) or 19 to 36 (High)

  • Payout: 1 to 1.

  • Probability:

    • European: 18/37 ≈ 48.65%
    • American: 18/38 ≈ 47.37%
    • French roulette with La Partage returns half your bet if zero hits on these bets, effectively reducing house edge to ~1.35%.

The math here is straightforward: A $50 bet on red in European roulette gives you nearly a 49% chance of winning $50, doubling your stake. If you play French roulette with La Partage, and the ball lands on zero, you get $25 back instead of losing the full bet, softening the loss.

Roulette Payouts and House Edge Comparison

Understanding how payouts relate to probabilities and house edge is crucial. The table below summarizes these key metrics for main bet types across European, American, and French roulette variants:

Bet Type Payout Probability (Europ.) House Edge (Europ.) Probability (Am.) House Edge (Am.) House Edge (Fr. La Partage)
Straight Up 35:1 2.70% 2.70% 2.63% 5.26% 2.70%
Split 17:1 5.41% 2.70% 5.26% 5.26% 2.70%
Street 11:1 8.11% 2.70% 7.89% 5.26% 2.70%
Corner 8:1 10.81% 2.70% 10.53% 5.26% 2.70%
Six Line 5:1 16.22% 2.70% 15.79% 5.26% 2.70%
Column/Dozen 2:1 32.43% 2.70% 31.58% 5.26% 2.70%
Even Money 1:1 48.65% 2.70% 47.37% 5.26% ~1.35%

Note: House edge represents the average loss per $100 wagered. The French roulette’s La Partage rule significantly reduces the house edge on even-money bets, making it more favorable for players focusing on low-risk wagers.

Understanding Inside vs Outside Bets in Practice

One of the most common questions among newcomers: “Should I bet inside or outside?”

The tradeoff is stark: inside bets are like going for a jackpot — the payout is tempting but the odds are quite low. For instance, betting $5 on a single number at an American table means you have less than a 3% chance of winning that $175. Conversely, placing the same $5 on red or black nearly doubles your chance of winning, albeit with a 1:1 payout.

On a $200 bankroll, that looks like betting $5 on a single number every spin. Statistically, you'd expect to win about once every 20 spins (American roulette). That single win would pay $175, but with 19 losing spins, you lose $95, resulting in a net gain of $80 over 20 spins. However, the house edge ensures that over many thousands of spins, the losses accumulate.

Alternatively, betting $5 on red every spin gives you about a 47% chance to win each time, doubling your stake, but with a lower payout, your wins and losses tend to even out more steadily. This is a more conservative approach that suits players looking to extend their playing time.

Notably, the French roulette’s La Partage rule softens the sting of losing even-money bets when the ball lands zero, returning half your stake. This effectively halves the house edge on these bets to roughly 1.35%, making even-money bets on French roulette the most player-friendly option.

Responsible Play: Managing Your Bankroll on the Betting Grid

Consider a common scenario: you sit down with a $100 bankroll, set a win goal of $50 and a loss limit of $60. You stick to outside bets — $10 on red, $10 on the second dozen — and resist the urge to chase a straight-up hit after three misses in a row. That discipline is what separates a two-hour session from a twenty-minute wipeout. No betting system changes the house edge, so the only variable you actually control is how fast you burn through your chips.

Here’s a practical bankroll management guideline based on risk tolerance and bankroll size:

Bankroll Size Suggested Bet Size Risk Level Recommended Example Scenario
Up to $100 $1–$5 Low (outside bets) Betting $2 on red/black for 50 spins, aiming for steady wins
$100–$500 $5–$25 Mix of outside + some inside bets Combining $10 splits with $15 dozen bets to balance risk
$500+ $25+ Balanced or aggressive Using $50 straight ups occasionally with $25 column bets

No betting system—whether Martingale, Fibonacci, or others—can overcome the house edge embedded in the roulette betting grid payouts and probabilities. Always set limits before you play and stick to them. For more on how rules like La Partage impact your bankroll, see our article on French Roulette Complete Guide.

Try It Yourself

The math works out to understanding the roulette betting grid is one thing; seeing it in action is another. Our interactive roulette simulator lets you place inside bets like splits and corners or outside bets such as dozens and red/black and immediately see how payouts work in practice.

Take a European wheel and test a $10 straight-up bet on number 7 and compare it to covering a dozen numbers for the same stake. Over 100 simulated spins, you’ll notice the straight-up bet hits about 2-3 times (European wheel), while the dozen bets win roughly 30-35 times. You can also experiment with French roulette’s La Partage rule to observe how it affects your bankroll over time.

This hands-on approach embeds the math and probabilities into your intuition, making you a smarter player when you hit a real table. To get started, visit our Roulette Table Layout Complete Overview and try different bet combinations.

Frequently Asked Questions

What is the difference between inside and outside bets on the roulette betting grid?
Inside bets are placed on specific numbers or small groups of numbers within the grid, offering higher payouts but lower chances of winning. Outside bets cover larger groups such as red/black or dozens, have higher probabilities of winning, and pay less.

How do payouts differ between European and American roulette?
Payouts for the same bet are identical on both wheels, but the presence of the double zero (00) in American roulette increases the house edge from 2.70% to 5.26%, meaning you lose more on average over time.

Does any betting system reduce the house edge on roulette bets?
No. All betting systems (Martingale, Labouchere, Fibonacci) cannot change the fixed house edge determined by the wheel's design and payout structure.

What is the La Partage rule in French roulette?
La Partage returns half your even-money bet if the ball lands on zero, effectively reducing the house edge on those bets to approximately 1.35%, making French roulette more favorable for cautious players.

Can I use the roulette betting grid to place multiple bets at once?
Yes, many players combine inside and outside bets simultaneously to cover different outcomes and balance risk and reward. For example, placing a dozen bet along with a few splits to diversify chances.

Final Thoughts

The roulette betting grid is not complicated once you stop seeing it as a mystery and start seeing it as a price list. Every bet has a cost (the house edge), a probability, and a payout. Your job is to pick the combination that matches your bankroll and your tolerance for variance. A $200 bankroll on inside bets is a short, volatile ride. The same $200 on outside bets is a longer, steadier one. Neither is “wrong” — but only one of them is a conscious choice.
