Crystal Roulette rule card: the sample table in figures
We picked Pragmatic Play's Crystal Roulette as our sample table. It is classic European roulette, its rules are on the studio's site, and two independent reviews give the same RTP. The third column shows where each figure comes from.

In the studio's own words this is a ‘fresh take’ on European roulette, yet the maths stays the same: one zero, 37 pockets. You will find it next to the other live tables under Dukat.bet live roulette. The Roulette tag is not applied to every table consistently, so if a name is missing, check the general live category too.
We left out the table limit on purpose: you only see it on the open table, and it can change.
Wheel, ball, croupier: what happens behind the table
A European wheel has 37 pockets. The numbers are arranged so red and black alternate, with the green zero apart. The croupier spins the wheel one way and launches the ball the other.
Small metal deflectors on the rim knock the ball off its path, so every spin differs and nobody can work out where it will stop. Once the ball settles, the system records the number and the payout appears almost at once.
On your side is a digital betting layout, with a countdown showing how long the table accepts bets. When it runs out, the layout locks and a late bet does not make the round.
Some tables have no dealer and a machine fires the ball. Their pace differs; see the auto roulette rule card.
European, French, American roulette: the price of the zero
The biggest difference between roulette variants is the number of zeros. Colours, bet types and payout ratios are broadly the same. Payouts, however, are set as if the zero did not exist, and the house lives in that gap.
| Variant | Pockets | Zeros | House edge | Note |
|---|---|---|---|---|
| European | 37 | 1 | 2.70% | most live tables are like this |
| French (La Partage) | 37 | 1 | 1.35% on even-money bets, 2.70% on the rest | half the stake comes back on zero |
| American | 38 | 2 | 5.26% | for comparison only |
The American wheel is only a theoretical reference here; we name no Dukat.bet table of that kind. The French roulette rule card works out when La Partage matters and when it does not.
Short rule: one zero always beats two.
Numbers or colours: the two groups of roulette bets
The layout splits into two parts. Inside bets sit within the number grid: one number, two neighbouring numbers, a row of three, a corner of four or two rows of six. Fewer numbers mean a bigger payout and a rarer hit.
Outside bets sit along the edge of the grid: dozen, column, red or black, odd or even, 1–18 or 19–36. They win more often but pay less. Even-money bets (1:1) lose precisely on the zero, because the green pocket belongs to neither group.
Coverage and odds for every bet, plus the racetrack call bets, are in our roulette bets table. Here it is enough to know that every standard bet on a European wheel carries the same 2.70% house edge.
One spin at the Crystal Roulette table, step by step
One round, as you see it on screen.
- Joining. The stream and betting layout load, with chip values and the table limit shown.
- Betting window. The countdown starts. You place chips, say on one number and on red; the racetrack lets you bet in wheel order too.
- Closing. Time runs out, the layout locks, the croupier spins.
- Spin. The close-up camera follows the ball round the transparent wheel; you only watch.
- Result. The ball stops, say on 23, which is red, and the number is highlighted.
- Settlement. Red pays 1:1, the number bet is lost. After the credit, a new window opens.
Between steps 4 and 5 you decide nothing: in roulette every choice happens inside the betting window.
What 2.70% means over an evening of roulette
On a single bet the house edge is small. Against your total turnover, it shows.
Illustrative calculation (not Dukat.bet data): say you bet 1,000 HUF on red in each of 60 rounds. Your turnover is 60,000 HUF. The expected loss is 1/37 of that, roughly 1,622 HUF. That is an average; a real evening can land well above or below it.
A bet on a single number feels different. It has a 1/37 chance per round, so over 37 rounds there is about a 36% chance your number never lands at all. The expected value is the same, the swings are much larger.
The number of rounds matters as much as the stake. To plan money and time in advance, see our session limits page.
What the roulette lobby tile does not tell you
A lobby tile shows a name, an image and a studio. Much of what matters appears only on the open table, or not at all.
- The limit. Minimum and maximum stakes show only on the open table; we do not publish them.
- The RTP version. With multiplier roulette a table can have two RTPs, and the base payout is not always 35:1. More on the multiplier roulette page.
- Dealer language and opening hours. Not verified by us, so not stated.
- The tag. Not every roulette table sits under Roulette; check the general live list too.
Dukat.bet's main live offer is the Live Casino Bonus – 500% up to 3,000 EUR + 15% Cashback. Point 2.14 of the general bonus terms, however, excludes live games from wagering; whether this offer differs is in its own terms, so read them first. Adults only, and only with cash you have earmarked for fun.
