RNG roulette vs live roulette

RNG roulette vs live roulette: the short answer

If both games use a single-zero wheel and standard payouts, the odds are identical. A straight-up bet wins 1 time in 37 and pays 35 to 1 whether the number comes from software or a ball, so the house edge is 2.70% in each case. An American double-zero version costs 5.26% in either format, and French rules cut even-money bets to 1.35% in either format.

What you're really choosing is the experience: a fast, low-stake game you control alone, or a slower game with a real wheel and dealer. That choice affects how much you put through in an hour, which is what decides your average cost. The sections below go through each difference, with the maths.

How RNG roulette picks a number

RNG roulette uses a random number generator, a piece of software that produces numbers which are then mapped to the 37 (or 38) pockets of a simulated wheel. The wheel and ball you see on screen are an animation of a result that has already been decided.

The Gambling Commission's RTS 7 standard on random outcomes (opens in a new tab) sets the rules. Results must be 'acceptably random', the output should be uniformly distributed, and it should be computationally infeasible to predict the next number. Where a game simulates a physical device such as a wheel, its theoretical probabilities should match the real thing, so a simulated single-zero wheel must give each pocket a 1-in-37 chance. Compensated (adaptive) games, which adjust results to hit a target return, aren't allowed.

Before release, the Commission's testing strategy (opens in a new tab) requires RNG testing that covers documentation, source code and statistical tests of raw output, and new games can only go live once the report has reached the Commission. Our page on how casino games are tested explains the role of approved test houses.

How live roulette produces a result

Live roulette uses a real wheel and ball, filmed and streamed to you, with the result read from the table and fed into the game software. Some live tables use a dealer to spin, while others, such as Evolution's Auto Roulette, use a fully automated precision wheel with no dealer at all. Evolution's Lightning Roulette uses an Auto Roulette wheel to launch the ball while a presenter hosts.

The Commission's guidance treats the wheel as a mechanical random number generator. The physical items that decide the result shouldn't be altered, and players shouldn't be able to touch or interfere with them. The result is still random, but the randomness comes from physics rather than code. Our live roulette guide covers the table types in detail.

RNG and live roulette compared side by side

Edges in the table assume standard payouts. Multiplier games such as Lightning Roulette change the payouts in both their live and RNG versions, so read each game's help screen.

Why the odds are the same in RNG and live roulette

The house edge comes from the gap between the payout and the true odds, and that gap is set by the paytable and the number of pockets, not by how the number is picked. A single-zero wheel has 37 pockets but pays every bet as if it had 36. As long as each pocket is equally likely, which the rules require of RNG games and which a well-kept physical wheel delivers, the edge is 1/37.

Worked example for a £10 straight-up: over 37 spins on average you win once (+£350) and lose 36 times (−£360), a net −£10 across £370 staked, which is 2.70%. That's the same at a live table or on screen. Our roulette odds page lists every bet.

Speed and cost per hour: RNG roulette vs live roulette

Since the edge per spin is the same, the format that lets you play more spins costs more per hour. RNG roulette has no betting window to wait for: under UK rules a non-slot casino game must allow at least 5 seconds per game cycle, which caps it at 720 rounds an hour, though few people play that fast. A standard live table runs at roughly 50 seconds a round, going by Evolution's figure that its 25-second Speed Roulette is about half a standard round.

The RNG paces are examples, not measured rates; your own pace will differ. The point is that the format doesn't change the price per spin, it changes how many spins you buy. Our guide to cost per hour shows the method for any game.

Can a live roulette wheel be biased?

A physical wheel is a machine, and in theory a worn or tilted wheel could favour some numbers. History has examples: Joseph Jagger exploited a biased wheel at Monte Carlo in 1873. Software can't wear out in the same way, which is one reason RNG games rely on statistical testing instead.

In practice, spotting bias takes a huge sample. Wizard of Odds' analysis of reader spin data (opens in a new tab) looked at one number that hit 278 times in 8,672 spins, against the 234.38 you'd expect (8,672 ÷ 37). Even that sizeable surplus still had a 1 in 466 chance of being pure luck. A live table's history board shows a few hundred spins at most, far too few to tell bias from normal variation, and the Commission's guidance says the equipment shouldn't be altered or touched by players. Our page on wheel bias and the question do roulette wheels have bias go further.

First Person games: RNG roulette with a live look

Evolution's First Person Lightning Roulette (opens in a new tab) is an RNG game. It uses 3D animation, and the wheel spins are decided by a random number generator, but its design and bets mirror the live version. A 'Go Live' button takes you from the First Person game to the live table of the same game. It's a handy way to learn a game at your own pace before joining a dealer table. See first person casino games for the full range.

How to choose between RNG and live roulette

1. Decide your budget for the session and your stake per spin.
2. Pick the wheel first: single zero (2.70%) or French rules (1.35% on even-money bets), never double zero if you can avoid it.
3. If you want a slow pace, a real ball or a dealer to chat to, choose a live table.
4. If you want small stakes, no waiting or to learn the layout privately, choose RNG.
5. Open the help screen and check the RTP, the payouts and the limits; multiplier games change them.
6. Work out your likely hourly cost: stake × spins an hour × edge.
7. Use the casino's time and spend display, and stop when the budget is gone.

RNG and live roulette myths

• 'RNG roulette is rigged to take more.' UK rules ban compensated games and require a simulated wheel to match a real one's probabilities. See is online roulette random.
• 'Live roulette is easier to beat.' The payouts set the same edge. No betting pattern or system changes it on either format.
• 'The RNG knows how much you've bet.' Results must be random and independent of your stake; the casino doesn't steer outcomes to individual players.
• 'A number is due because it hasn't hit.' Every spin is independent. The gambler's fallacy applies equally to software and ball.

UK rules that apply to both formats

Since 17 January 2025, autoplay has been banned for all online casino games, RNG and live alike, although a re-bet button is allowed. Non-slot casino games must allow at least 5 seconds per game cycle, you can't play several games at once, and net spend and time played must be shown in real time. Rules, payouts and RTP must be available before you bet. The £5 and £2 online slot stake caps don't apply to roulette in either format. Our remote technical standards page explains the detail.
