RNG (Random Number Generator) is a software system that generates random outcomes for games that are not based on live physical equipment.
Licensed online casinos such as Split.com, use RNG systems that are tested and certified by independent laboratories. These tests verify that outcomes are statistically random and that the games pay according to their published mathematical models over the long run.
The RNG continuously produces random numbers. When you perform an action—such as spinning reels, dealing cards, rolling dice, or spinning a virtual wheel—the game uses the next random number (or numbers) to determine the outcome. Each game maps those random numbers differently.
RNG is the technology that provides random outcomes in software-based online casino games, including slots, virtual table games (such as roulette, blackjack, baccarat, and poker), dice games, keno, scratch cards, and other digital casino games. Live dealer games, by contrast, generally rely on physical equipment rather than an RNG to determine the main game outcome.
