One of the most important pieces that determines how online casino software works is random number generators (RNG). Every legal, regulated online casino will utilize RNG to determine game outcomes, ensuring that games are fair and not rigged. Essentially, every time you have a hand dealt, spin a roulette wheel or slot machine, or participate in any other online casino game, random numbers will be generated in the backend to determine the outcome of your action.
Physical land-based casinos also utilize RNG for all slot machines and other digital games. For table games, the shuffled decks of cards serve as the RNG. Whether you’re playing online or in-person, the odds are the same.
