Article Summary
1. Random Number Generators in Casino Games
Random Number Generators (RNG) in casino games are algorithms used to produce unplanned sequences of numbers, ensuring fair and unpredictable outcomes.
2. How Do Casino RNGs Work?
Casino RNGs constantly produce random numbers, which is crucial for determining outcomes like spins or card deals. Each result is independent and ensures fairness by remaining unpredictable.
True RNG vs. Pseudo-RNG
True RNGs use physical phenomena for randomness, while pseudo-RNGs rely on algorithms. Pseudo-RNGs are prevalent in online gambling due to their speed and efficiency.
3. Are Casino RNGs Provably Fair?

Our Expert’s Advice
“If RNG certification isn’t available on a casino’s official site, you can request it from the support team. Don’t be shy – transparency is vital to a trustworthy gaming session.”
6. Which Casino Games Use RNGs?
All non-live casino games use RNGs. Meanwhile, live games rely on human dealers, except for occasional RNG-based features in some titles, like Lucky Numbers in Evolution’s Lightning Roulette.
RNGs in Slots
In slots, the RNG determines the outcome of each spin by selecting a random number corresponding to a symbol on each virtual reel.
RNGs in Table Games
For virtual table games, the RNG assigns random numbers to cards or roulette wheel pockets. A random number selection then determines the outcome, simulating a real-world deal or spin.
7. Can You Outsmart an RNG?
You cannot outsmart the algorithm. With millions of number combinations generated per second, no such thing as an online casino RNG loophole exists.
