Roulette has more bet types than most table games. The layout looks complicated at first glance but the underlying math is clean. Every bet falls into one of two categories: inside bets placed directly on numbers and outside bets placed on broader groupings. The payout for each bet is fixed. The house edge depends on the wheel.
This chart covers every standard bet you can make. Bookmark it. Print it. Pull it up on your phone at the table. Knowing what you are paid and what you are actually risking is the baseline for any informed approach to the game.
Inside Bets
Inside bets are placed on the numbered grid. They cover fewer numbers and pay more. The tradeoff is lower probability of hitting.
| Bet Type | Numbers Covered | Payout | European Odds | American Odds |
|---|---|---|---|---|
| Straight Up | 1 | 35:1 | 2.70% | 2.63% |
| Split | 2 | 17:1 | 5.41% | 5.26% |
| Street | 3 | 11:1 | 8.11% | 7.89% |
| Corner (Square) | 4 | 8:1 | 10.81% | 10.53% |
| Five-Number (Basket) | 5 | 6:1 | N/A | 13.16% |
| Six Line (Double Street) | 6 | 5:1 | 16.22% | 15.79% |
The five-number bet only exists on American wheels. It covers 0, 00, 1, 2 and 3. At 7.89% house edge it is the single worst bet on the entire table. There is never a reason to place it.
Outside Bets
Outside bets sit around the edges of the number grid. They cover larger groups and pay less but hit more frequently.
| Bet Type | Numbers Covered | Payout | European Odds | American Odds |
|---|---|---|---|---|
| Column | 12 | 2:1 | 32.43% | 31.58% |
| Dozen | 12 | 2:1 | 32.43% | 31.58% |
| Red / Black | 18 | 1:1 | 48.65% | 47.37% |
| Odd / Even | 18 | 1:1 | 48.65% | 47.37% |
| High (19-36) / Low (1-18) | 18 | 1:1 | 48.65% | 47.37% |
Every outside bet loses when the ball lands on zero. On American wheels they also lose on double zero. That is the entire mechanism of the house edge. The payouts are calculated as if those green pockets did not exist.
The House Edge on Every Bet
On a European wheel with one zero the house edge is 2.70% on every bet except one. On an American wheel with two zeros it jumps to 5.26% across the board with the five-number bet climbing to 7.89%.
The Math Behind the Edge
Take a straight-up bet on European roulette. There are 37 pockets. You win on 1 of them. The true odds are 36:1 but the payout is 35:1. That gap of one unit across 37 outcomes is 1/37 = 2.70%. The same logic applies to every bet on the table. The payout is always set one unit lower than the true odds.
This is important to understand. The house edge does not change based on what you bet. A straight-up number at 35:1 carries the exact same mathematical disadvantage as a red/black bet at 1:1. The difference is volatility. Inside bets produce bigger swings. Outside bets produce smoother results. But the cost per dollar wagered is identical.
Expected Loss Per Hour
The house edge tells you what you lose per dollar bet. To figure out what a session actually costs you need three numbers: your average bet size, the number of spins per hour and the house edge.
| Avg Bet | Spins/Hour | European (2.70%) | American (5.26%) |
|---|---|---|---|
| $10 | 35 | $9.45/hr | $18.41/hr |
| $25 | 35 | $23.63/hr | $46.03/hr |
| $50 | 35 | $47.25/hr | $92.05/hr |
| $100 | 35 | $94.50/hr | $184.10/hr |
These are long-run averages. In any single session you might win or lose substantially more. But over dozens of sessions this is what the math converges toward. The American wheel costs almost exactly double per hour of play.
French Roulette and La Partage
French roulette uses the same single-zero wheel as European but adds a rule called La Partage. When the ball lands on zero your even-money bets lose only half instead of the full amount. This cuts the effective house edge on red/black, odd/even and high/low bets to 1.35%.
At 1.35% the expected hourly loss on a $25 even-money bet at 35 spins per hour drops to $11.81. That makes French roulette one of the lowest house edge games in the entire casino. If you can find a table offering La Partage or the similar En Prison rule it is always the best option available.
What This Chart Does Not Tell You
Payout charts show you the structure of the game. They tell you what is mathematically true on every spin. What they do not capture is variance. Two players can place the same number of bets at the same stakes on the same wheel and walk away with wildly different results over a single session. That is normal. The chart describes the long-term expectation. Your actual experience in any given session will deviate from it, sometimes dramatically.
Understanding the payouts is the starting point. Managing your bankroll around them is where the real work begins.
