RNG stands for Random Number Generator - a type of computer program.
RNG does exactly what the name suggests – generates numbers that are random. It does this constantly, generating a new set of randomized numbers in a fraction of a second and repeating the process.
RNG imitates the actions that take place in a live casino and then displays the outcomes virtually on the computer screen using graphics. Every time you press a button to make a spin, RNG supplies the game with a random number and the game expresses the number in a format of slot machine symbols. This also means that the outcome of the game is completely random.
The Random Number Generator (RNG) used by Chumba Casino utilizes a Mersenne Twister with background cycling. This was certified by iTechLabs and Gaming associates who confirmed that they use a well-known algorithm to generate random numbers. The numbers generated by these RNG have passed Marsaglia's "diehard" tests for statistical randomness. iTech Labs and Gaming associates have found that number sequences are unpredictable, non-repeatable, and uniformly distributed.
