The Ratio Is the Payout, Not the Chance of Winning
You are looking at a bet that returns 6 units for every 17 units you stake, on top of your original wager. The phrase "pays 6 to 17" is a payout ratio. It tells you what the house will hand back if your bet wins. It does not tell you how likely the bet is to win. Those are two different numbers, and confusing them is the most common way players misread a roulette layout or a game information panel.
In roulette, payouts are almost always written as "X to Y" or "X for Y." The small difference between those two prepositions matters. "Pays 6 to 17" means you receive 6 units of profit for every 17 units wagered, and you also get your 17 units back. "Pays 6 for 17" would mean you receive 6 units total, which includes your stake. Most roulette tables use the "to" form, but the wording on a specific table or screen is the only thing that settles it.
How the Payout Connects to the Wheel
A roulette payout ratio exists because the wheel has a fixed number of pockets and each bet covers a fixed number of them. The payout is built from the number of pockets the bet does not cover, divided by the number it does cover. A bet that covers 17 pockets on a wheel with 37 total pockets leaves 20 uncovered. The fair payout for that bet, if the house took no edge at all, would be 20 to 17. A payout of 6 to 17 is far below that, which tells you the bet carries a heavy house advantage.
European wheels have 37 pockets, numbered 0 through 36, with a single zero. American wheels have 38 pockets because they add a double zero. The extra pocket changes the relationship between every bet and its payout. A ratio that appears on one wheel type does not automatically mean the same thing on the other, because the number of uncovered pockets changes while the payout often stays fixed.
Where a 6 to 17 Payout Could Appear
Roulette layouts list payouts for the standard bets: straight-up, split, street, corner, six-line, dozen, column, and the even-money outside bets. A 6 to 17 ratio is not one of the standard printed payouts on a conventional single-zero or double-zero layout. When a player sees that figure, it usually comes from one of three places: a side bet, a promotional wager, or a game variant with altered pay tables.
Some roulette variants add side bets with names like "lucky numbers," "hot zones," or similar branded labels. These side bets often cover unusual groups of numbers and carry payout ratios that do not match the main table. A side bet covering 17 specific numbers might be listed as paying 6 to 17. The ratio tells you the bet is a poor one relative to the wheel, because 17 covered numbers on a 37-pocket wheel would fairly pay 20 to 17, not 6 to 17.
Promotional wagers can also carry odd ratios. A casino may offer a special bet with a headline payout that looks generous but is below the mathematical fair value. The only way to know what a specific 6 to 17 bet covers is to read the table rules or the game information panel for that exact title and rule set.
Converting the Ratio to Money
To turn a payout ratio into a cash figure, divide the first number by the second and multiply by your stake. For a 6 to 17 payout, divide 6 by 17. That gives roughly 0.353. A 17-unit bet would return 6 units of profit. A 34-unit bet would return 12 units. A 170-unit bet would return 60 units. The arithmetic scales linearly: any stake multiplied by 6 and divided by 17 gives the profit.
Suppose, as an example, you place 85 units on a bet that pays 6 to 17 and it wins. Your profit is 85 multiplied by 6, divided by 17, which equals 30 units. You also receive your original 85 units back, for a total return of 115 units. If the bet loses, you lose the full 85 units.
What the Ratio Hides About the House Edge
A payout ratio only becomes meaningful when you compare it to the probability of winning. The house edge on any roulette bet is the gap between the payout the house offers and the payout a bet would carry if the wheel had no zero. The zero, or zeros, are the pockets that create that gap. On a European wheel, every bet's true odds are calculated against 37 pockets, but the house pays as if the zero did not exist for most standard bets.
The same principle applies to any unusual payout like 6 to 17. If the bet covers 17 pockets on a 37-pocket wheel, the probability of winning is 17 divided by 37. The fair payout would be 20 to 17. A payout of 6 to 17 means the house is keeping a very large share of the bet's mathematical value. The exact house edge is the difference between the fair payout and the offered payout, expressed as a percentage of the wager. That percentage is not printed on the layout, but the player can calculate it from the wheel's pocket count and the bet's coverage.
| Bet Type | Pockets Covered (European Wheel) | Fair Payout (No Zero) | Typical Printed Payout |
|---|---|---|---|
| Straight-up | 1 | 36 to 1 | 35 to 1 |
| Split | 2 | 17.5 to 1 | 17 to 1 |
| Street | 3 | 11.33 to 1 | 11 to 1 |
| Corner | 4 | 8.25 to 1 | 8 to 1 |
| Six-line | 6 | 5.17 to 1 | 5 to 1 |
| Dozen or column | 12 | 2.08 to 1 | 2 to 1 |
| Even-money | 18 | 1.06 to 1 | 1 to 1 |
| Hypothetical 17-number bet | 17 | 20 to 17 | 6 to 17 (as given) |
The table shows the pattern. The printed payout is always slightly below the fair payout. The gap is the house edge. A 6 to 17 payout on 17 covered numbers is an extreme version of that gap, which is why it stands out to anyone who does the arithmetic.
Reading the Table Before You Bet
Before placing any roulette wager, find three things on the layout or the game screen. First, the wheel type: count the zeros. A single zero means 37 pockets; a double zero means 38. Second, the bet's coverage: how many numbers does the bet include. Third, the payout ratio printed next to the bet name. Those three pieces of information let you work out whether the bet is a standard wager or a side bet with an unusually large house edge.
For side bets and promotional wagers, the rules panel is the authoritative source. It states the covered numbers, the payout, and any conditions such as a maximum stake or a qualifying spin. If the panel does not clearly state all three, treat the bet as unreadable and do not place it. A payout ratio without coverage information is not enough to make a decision.
Common Procedural Mistakes at the Table
New roulette players make a small set of procedural errors that cost them money or create confusion. The first is placing a bet after the dealer has called no more bets. Once the ball is in motion and the dealer closes betting, any chips placed on the layout are void or returned, depending on the house procedure. The second is touching chips after the winning number is announced. The dealer pays winning bets and clears losing ones in a specific order; moving chips during that process can lead to a dispute about what was wagered.
The third mistake is misreading a payout ratio as a probability. A bet that pays 6 to 17 does not win 6 times out of 17. It pays 6 units for every 17 staked when it wins. The chance of winning is determined by the wheel, not by the payout ratio. Keeping those two concepts separate is the single most useful habit a new roulette player can form.
FAQ
Does a 6 to 17 payout mean I win 6 times out of 17 spins?
No. The ratio describes the money returned on a winning spin, not the frequency of wins. The probability of winning depends on how many pockets the bet covers and how many total pockets the wheel has. A payout ratio and a probability are different measurements.
Is a 6 to 17 payout better or worse than an even-money bet?
It depends on the coverage. An even-money bet on a European wheel covers 18 pockets and pays 1 to 1. A 6 to 17 bet covering 17 pockets would pay less than the fair 20 to 17 ratio, so it carries a much larger house edge despite the similar coverage. The payout alone cannot tell you which bet is better; you need the coverage and the wheel type.
Where can I find the exact payout for a specific roulette side bet?
On the table layout itself for land-based play, or in the game information panel and rules screen for online play. The panel should list the covered numbers, the payout ratio, and any maximum stake or qualifying condition. If the information is not clearly stated, ask a dealer or support representative before wagering.
