Spin a digital roulette wheel and the result exists before the animation starts. The ball you watch bouncing around the screen is decoration: the number was drawn by software the moment you confirmed your bet. Live tables reverse that order. The croupier spins, the ball drops, and only then is there a result for the software to read. Where the number comes from is what separates RNG vs live dealer roulette. For fairness it matters less than most players think; for pace, more than most notice.
Below, the two are compared on the points that change a session: the source of the result, how each is tested, the house edge, speed, limits, and when each one makes sense. For the studios, formats and casinos behind the live tables, see our main live roulette page.
Where the number comes from
An RNG roulette game uses a random number generator, an algorithm that produces a stream of numbers too long and too evenly spread for any pattern to show. Each spin takes the next value at the moment you bet and maps it to a pocket: one of 37 on a European wheel, one of 38 on an American one. The animation that follows is drawn to match.
A live game uses a physical wheel in a studio. A croupier, or a launcher on auto tables, spins the wheel and the ball, the wheel reports the winning pocket to the game software, and the software settles your bet. There is no algorithm choosing the number; there is a ball, a rotor and physics.
Both systems produce results that cannot be predicted. The RNG gets there by mathematics and testing, the live wheel by engineering and maintenance.
How each is tested
At a regulated casino, an RNG game has to pass a laboratory before it reaches players. Testing labs such as Gaming Laboratories International (GLI) run the generator’s output through statistical tests and check that the game pays what its rules say. GLI’s standard for online gaming systems, GLI-19, is one of the documents labs work to. In Ontario, the games must also meet the AGCO’s Registrar’s Standards for Internet Gaming.
A live wheel is tested differently, because it is hardware. Studios maintain and inspect their wheels, the studio supplier is registered with the regulator, and the casino carrying the table answers for it. The risk a regulator watches on a physical wheel is wear: a tilted rotor or loose pocket can bias the results, and maintenance schedules exist to catch exactly that. Our fairness guide tells the history of wheel bias and how it is caught.
The same wheel keeps the same edge
This is where the two games are identical. The edge comes from the zero pockets and the payouts, and neither cares whether the number came from code or from a ball.
Swipe the table
| Wheel and rule | House edge | Theoretical return |
|---|---|---|
| European or French, single zero | 1/37 = 2.70 % | 97.30 % |
| French, La Partage on even-money bets | 1/74 = 1.35 % | 98.65 % |
| American, double zero | 2/38 = 5.26 % | 94.74 % |
A C$10 straight-up on a single-zero wheel wins 35 to 1 once in 37 spins on average, whichever version you play. The only games where RNG and live can differ are the multiplier versions, where each title sets its own payouts and multiplier odds. Pragmatic Play publishes a 97.50 % RTP for its live Mega Roulette 3000; most multiplier titles publish nothing. Our house edge guide works through every bet type.
Speed: the difference that costs money
If the edge is the same, the cost per hour is set by how many spins you play. Here RNG and live are far apart.
A live dealer table runs at about a minute or a little less per spin. Evolution describes the 25 seconds of its Speed Roulette as roughly half a standard round, which puts a normal table near 70 spins an hour. Auto Roulette, without a croupier, runs 60 to 80 games an hour by Evolution’s figures. Speed Roulette tops out around 144.
An RNG game has no croupier, no betting window and no ball to wait for. It runs as fast as you click. Suppose you take 12 seconds per spin, which is not fast for a digital game: that is 300 spins an hour.
A word on autoplay and quick-spin buttons, where a game offers them: they remove the pause between spins entirely, and that is where the RNG’s pace turns from a convenience into the main cost of the session. If you use one, set the number of spins in advance and a loss limit with it.
Now put the same C$2 on a dozen at a single-zero wheel in each setting:
- Live dealer table, about 72 spins: C$144 staked, expected cost C$144 × 1/37 = C$3.89.
- RNG game, 300 spins: C$600 staked, expected cost C$600 × 1/37 = C$16.22.
Same game, same edge, four times the cost. Nothing about the RNG is unfair. You have just bought four times as many spins. If you set yourself a session budget, the pace of the game decides how long it lasts more than any bet choice does, and our responsible gambling page covers how to set limits in your casino account.
(A reader who plays RNG roulette slowly, with a pause between spins, gets most of the live table’s pace without the stream. Few people do.)
Three beliefs that do not survive the maths
“The software knows what I bet.” In a certified RNG game the number is drawn without reference to your stake or your bet type; labs test for exactly that kind of link before approval. A losing streak after a win feels personal. It is the same 2.70 % working through ordinary variance.
“A live table has hot numbers.” Statistics panels on live tables show the last few hundred results, and some numbers will always look busy. On a well-maintained wheel each spin is independent of the one before, so the panel describes the past and says nothing about the next ball. Spotting a real bias takes many thousands of spins, and regulated studios inspect their wheels so that one does not develop.
“Live is safer because it is slower.” Slower is cheaper per hour, and that is a genuine advantage. It does not lower the edge on a single bet, and a player who raises stakes to make up for the slower pace ends up paying as much as on a fast game. The pace only helps if the stake stays where it was.
Limits: who takes the smallest stakes
RNG games accept the smallest stakes, often well under a dollar per chip, because a digital spin costs the casino almost nothing to run. Live tables carry the costs of a studio, staff and equipment for every hour they are open, so their minimums usually start higher. High-limit and one-on-one live tables, such as Playtech’s Prestige Roulette, start higher again.
At the top end the pattern reverses at many casinos: live tables tend to allow larger maximums than RNG versions. Each table sets its own range per bet type, and the same game can have different limits at different casinos, so the limits panel at the table is the only reliable source.
Features you get with one and not the other
RNG roulette usually offers a demo mode with play money, which makes it the natural place to learn the layout. It also lets you replay a favourite bet in one tap and takes no notice of time of day: there is never a full table.
Live roulette gives you a person, a chat box the croupier answers, and the visible proof of a ball landing in a pocket. Studios add multiple cameras, slow-motion replays and racetrack call bets. And since a live table cannot be paused for you, the betting timer builds in a short break between spins that RNG games do not have.
One format sits between the two. Evolution’s Instant Roulette runs 12 synchronised Auto Roulette wheels; you place a bet, pick a wheel, and the result arrives almost immediately. It is a physical wheel with an RNG game’s speed, and its pace should be treated like an RNG game’s for budgeting.
When each one makes sense
Our view, plainly: for anyone playing for money and for entertainment, live roulette is the better default. The edge is the same, the pace is slower, and a slower game costs less per hour at the same stake.
RNG roulette makes sense in three situations. When you are learning, a demo or our free practice wheel costs nothing. When your stakes are very small, an RNG table may be the only one that accepts them. And when you want a French table with La Partage and no live version is open, the RNG one keeps exactly the same 1.35 % on even-money bets.
What decides the cost of an evening is the wheel and the number of spins, not the source of the number. Choose a single-zero wheel either way. Then decide how many spins you want to pay for, and pick the game whose pace matches it.
There is one honest exception to everything above: some players simply find a ball more convincing than a certificate, and trust is part of what makes a game enjoyable. That is a perfectly good reason to choose live, as long as you know the maths did not change.
