Live dealer games sit in a genuinely different category from the slots and RNG table games most players are used to, and the technology behind them explains why they feel so different to play.
The Physical Setup
A live dealer table is a real, physical table, usually in a dedicated studio rather than a public casino floor, staffed by a professional dealer and filmed by multiple cameras simultaneously. A typical blackjack or roulette table runs several camera angles at once — an overhead shot, a close-up on the cards or wheel, and a wider view of the dealer — all streamed live and switched between automatically as the action moves.
Optical Recognition and Game Sensors
What makes a live table function as an actual casino game, rather than just a video feed, is the recognition technology built into the setup. Optical character recognition software reads card values as they’re dealt, in real time, and feeds that information directly into the game software players are interacting with. Roulette wheels use a similar principle with sensors that track the ball’s position and confirm the winning number the instant it settles, removing any lag between the physical result and what appears on a player’s screen.
Why Live Games Differ From RNG Games
An RNG, or random number generator, game runs entirely on software: the outcome of a slot spin or an automated roulette wheel is generated by an algorithm, tested and certified for fairness, with no physical element involved at all. A live dealer game replaces that algorithm with a real, physical outcome — an actual card dealt from an actual shoe, an actual ball landing in an actual pocket — verified through the camera and sensor technology rather than generated by code. That’s the core distinction: RNG games are simulated, live dealer games are filmed.
Latency and Fairness
The biggest technical challenge in live dealer gaming is latency — the delay between something happening at the table and it registering on a player’s screen. Modern platforms have brought this down to well under a second in most cases, close enough to real time that betting windows can close and results can register without any meaningful lag. Combined with the optical recognition confirming every outcome independently of the dealer, this is what allows live tables to be certified as fair despite involving a human dealer rather than pure software.
