Live dealer games stream a real croupier, real cards and a real wheel to your screen, with bets placed through an on-screen interface. They sit between random-number-generator games and a physical casino, and their popularity has grown rapidly. The technology behind a live table is more elaborate than the video suggests, and understanding it explains several things players find odd: why results appear as text before the ball has stopped, why there is a betting timer, and why a live blackjack table can be shared by dozens of players.
The studio
Live games are broadcast from purpose-built studios. The largest providers operate from Latvia, Malta, Georgia, the Philippines and elsewhere, and supply the same tables to many casinos simultaneously. The dealer you see on one casino site may be visible on twenty others at the same moment. Some casinos commission dedicated tables with their own branding, but the studio and staff are usually the provider’s.
Studios run 24 hours a day. Dealers work in shifts, rotating tables at intervals, and are trained both in game procedure and in on-camera presentation.
Optical character recognition
Every card dealt and every roulette result is captured by cameras positioned above the table and read by optical character recognition (OCR) software. That data — not the video — is what the casino’s software uses to update your bet slip, calculate wins and settle bets. The video stream is for the player’s benefit; the game engine relies on the data feed.
This is why results often appear in a text overlay a fraction of a second before you can see them on screen: the OCR feed and the video feed travel through different pipelines with different latency.
The betting window
Because many players share a table, bets are accepted during a fixed window — typically 10 to 20 seconds — before the dealer announces “no more bets” and the interface locks. Bets not confirmed in time are rejected and the player sits out that round. This is different from a physical casino, where a dealer can wait for a hesitant player, and it takes some adjustment.
Game formats
| Format | How it works | Notes |
| Classic roulette | Standard European wheel, live dealer | Same house edge as RNG version |
| Speed roulette | Shorter betting window, faster spins | More rounds per hour; more staked per hour |
| Lightning-style roulette | Random numbers get multipliers each round | Straight-up payouts reduced to fund multipliers; RTP usually lower |
| Blackjack (unlimited seats) | One hand dealt; all players share it and make own decisions | Common in live formats |
| Blackjack (seated) | Seven seats, each player has their own hand | Closest to a physical table |
| Baccarat | Standard Punto Banco | Very popular in live format |
| Game shows | Wheel or dice-based games with bonus rounds | Rules and RTP vary widely; check each |
The game-show category — spinning money wheels, dice games, hybrid RNG-and-live formats — has grown fastest. These are entertainment products first, and their RTPs are generally lower than classic table games. The information page states the figures.
Fairness and oversight
Live studios are licensed and audited in the same way as RNG game providers. Typical controls include:
- Cards pre-shuffled in bulk by a third party, delivered in sealed shoes, and changed at set intervals.
- Roulette wheels are inspected regularly, with results monitored for statistical bias.
- Multiple camera angles recorded and retained.
- Dealers are unable to see individual player bets in most formats.
- Studio floor supervisors and pit managers present at all times.
Disputes — a disconnection mid-hand, a misread card — are governed by the operator’s terms. Usually a placed bet stands and is settled on the outcome; a misread result is corrected from the video record.
Practical differences from RNG games
| Aspect | RNG games | Live dealer |
| Pace | Player controls speed | Dealer controls speed; fixed betting windows |
| Minimum stake | Often from 10p | Frequently £1 or more; some tables £5+ |
| Demo mode | Usually available | Rarely available |
| Connection | Tolerant of drops | Needs a stable connection |
| Social element | None | Chat with dealer and other players |
| Bonus wagering | Usually 100% contribution | Often 10% or excluded |
What live dealer does not change
The house edge on live European roulette is the same 2.70% as on the RNG version. Live blackjack with basic strategy carries the same small edge as RNG blackjack under the same rules. The presence of a human dealer does not make the game beatable, and it does not make results less random. What it changes is atmosphere, pace and the sense of transparency — and, often, the minimum stake.
Points to check before playing
- The table’s minimum and maximum stakes.
- Whether side bets are optional (they usually are, and usually poor value).
- The RTP of any game-show or multiplier variant.
- How the operator handles disconnections.
- Whether live games count towards any bonus you are wagering.
