Roulette bets rule card: payout and odds out of 37 pockets
This card covers the single-zero European wheel. Every figure is a mathematical constant, not casino or table data. Our example is Pragmatic Play's Crystal Roulette, which has a racetrack and special bets.
| Item | Value | Source |
|---|---|---|
| Wheel | European, 37 pockets, one green zero | mathematical constant |
| What you bet on | a number, a group of numbers or the outside fields at the edge of the grid | mathematical constant |
| What decides | the winning number, which can settle several bets at once | mathematical constant |
| House edge | 2.70% on every standard bet | mathematical constant |

And the bet table itself, from the riskiest to the calmest:
| Bet | Numbers covered | Payout | Odds out of 37 |
|---|---|---|---|
| Single number (straight up) | 1 | 35:1 | 1/37 ≈ 2.70% |
| Split (two neighbours) | 2 | 17:1 | 2/37 ≈ 5.41% |
| Street (one row) | 3 | 11:1 | 3/37 ≈ 8.11% |
| Corner (block of four) | 4 | 8:1 | 4/37 ≈ 10.81% |
| Six line (two rows) | 6 | 5:1 | 6/37 ≈ 16.22% |
| Dozen or column | 12 | 2:1 | 12/37 ≈ 32.43% |
| Even money (colour, odd/even, low or high half) | 18 | 1:1 | 18/37 ≈ 48.65% |
One, two, three, four, six: the inside bet grid
Inside bets sit within the number grid of 3 columns and 12 rows. A chip can go on a number, on the line between two, at the end of a row or where four meet; the interface highlights it before you let go.
The payout logic is simple. The house pays as if there were 36 pockets: 36 divided by the numbers covered, minus the stake you get back. For one number that is 36/1 − 1 = 35, for a corner 36/4 − 1 = 8.
Zero is an inside number too: alone it pays 35:1, and it can join neighbours in a split or street if the interface allows.
Dozen, column, even money: the outside bet fields
Outside fields cover 12 or 18 numbers at once. A dozen is 1–12, 13–24 or 25–36; a column is one vertical line of the grid. Both pay 2:1.
Even-money bets cover half the numbers, but not half the wheel: zero belongs to neither group. It is the only pocket where red and black both lose.
At a French-rules table, half of an even-money stake comes back on zero. That applies only to these fields, not to dozens or columns; we work through the details on the French roulette rule card.
Why every roulette bet has an expected value of 36/37
This is roulette's key fact, and a surprise to many: no standard bet is cheaper than another; on average each takes the same share.
Illustrative calculation (not Dukat.bet data): put 1,000 HUF on three kinds of bet.
- Single number: with 1/37 odds you get back 36,000 HUF (35,000 win + stake). Expected return: 36,000 / 37 ≈ 973 HUF.
- Dozen: with 12/37 odds you get back 3,000 HUF. Expected return: 36,000 / 37 ≈ 973 HUF.
- Red: with 18/37 odds you get back 2,000 HUF. Expected return: again ≈ 973 HUF.
In all three cases the house keeps about 27 HUF of every 1,000 HUF. The difference lies in the variance: a chip on one number pays rarely but big, red pays often but little.
So no combination beats the wheel: several bets at once are just several 36/37 bets.
Voisins, Tiers, Orphelins: call bets on the racetrack
The racetrack is an oval strip showing the numbers in their real wheel order. Call bets placed on it are pre-built bundles of plain split and number bets, tied to sections of the wheel:
| Call bet | Numbers covered | Chips | What it covers |
|---|---|---|---|
| Voisins du Zéro | 17 | 9 | the large arc around zero |
| Tiers du Cylindre | 12 | 6 | the section opposite zero, six splits |
| Orphelins | 8 | 5 | the ‘orphan’ numbers between the two arcs |
| Jeu Zéro | 7 | 4 | the immediate neighbourhood of zero |
The neighbours bet belongs here too: a chosen number together with the two pockets either side of it on the wheel, five chips in all. Crystal Roulette's special bets are similar: Final en Plein covers numbers with the same last digit (for example 3, 13, 23, 33), Finales à Cheval covers pairs of last digits with splits, and Full Complete covers every inside bet around one number.
Key point: a bundle does not change the maths. Every bet inside it runs at a 2.70% house edge; more chips simply go out at once.
A roulette round with mixed bets, step by step
Here is a round where you place three kinds of bet at once.
- Betting window. You put 500 HUF on 17, 1,000 HUF on the second dozen (13–24) and 1,000 HUF on black. 2,500 HUF in total.
- Closing. The countdown ends and the croupier spins.
- Result, version one: 17. It is black and in the second dozen. The number bet returns 18,000 HUF, the dozen 3,000, black 2,000: 23,000 HUF in total.
- Result, version two: 20. Also black and second dozen, but not your number. You get back 3,000 + 2,000 = 5,000 HUF, a net result of +2,500 HUF.
- Result, version three: 0. All three bets lose, because zero is neither black nor in a dozen. Minus 2,500 HUF.
Settlement is automatic, then a new window opens with your next decision.
The roulette countdown: typical betting-time mistakes
At a live table, time is scarce: a few seconds for what you could ponder at leisure on an RNG wheel.
- Lag. A weak connection can lose a last-second bet, so do not wait for the final seconds.
- Repeat button. Handy, but if you doubled up last round, you can carry the bigger stake forward without noticing.
- Wrong chip value. After switching, check the selected chip before placing a call bet, since it multiplies.
- Multiplier table. On a multiplier version the base payout may not be 35:1; see the multiplier roulette page.

What the roulette layout does not tell you on its own
The layout shows where to bet, not everything else. Table minimums and maximums appear only on the open table (we do not publish them), call bets may have a separate cap, and not every interface shows the exact RTP version.
Wheel physics and the flow of a round are on the roulette rule card.
