RNG table games explained
RNG table games are digital versions of casino table games such as roulette, blackjack and baccarat, where software called a random number generator decides every card, spin or roll instead of a human dealer. There is no studio, no camera and no physical deck. Each result is drawn the instant the player confirms a bet, and it has no memory of the hand before it.
How the software deals the cards
The generator produces a stream of numbers, and the game maps each one to an outcome, such as one of 37 pockets on a European wheel or one card from a virtual shoe. Independent labs like GLI, eCOGRA, iTech Labs and BMM test that mapping over very large samples before a game goes live.
That certificate covers a specific build of the game, so a changed version needs fresh review.
House edge by game and bet
The figures below come from the payout rules themselves, not from any operator’s results. Blackjack varies most, because studios ship different rule sets under similar names.
| Game and bet | House edge | What sets it |
|---|---|---|
| European roulette | 2.70% | One zero pocket |
| American roulette | 5.26% | Zero and double zero |
| Baccarat, Banker | About 1.06% | 5% commission on wins |
| Baccarat, Player | About 1.24% | Fixed drawing rules |
| Baccarat, Tie at 8:1 | About 14.4% | Low payout for rare result |
| Blackjack | Roughly 0.5-1% | Rules and correct play |
What players get wrong about RNG
A house edge is a long-run average, never a forecast. On €500 of bets at European roulette, the expected loss is about €13.50, yet a single evening can land far above or below that figure.
Streaks do not make a result due.
Because every spin is drawn fresh, five reds in a row leave the next spin’s odds exactly where they were. What I check first in any title is the rules screen, since the payout table, rather than the generator, decides the edge.
RNG tables versus live casino
Live casino tables use a real dealer, a physical wheel or deck and a video stream, so an RNG certificate does not apply to them in the same way. Studio procedures and the operator’s licence conditions do that job instead.
RNG tables usually allow lower minimum stakes and faster rounds, which means more bets per hour and, at the same edge, a larger expected loss over that hour. Practice varies between operators, so limits are worth reading in each game’s own help page.
