Random Number Generator (RNG)

In the context of gambling, a random number generator (RNG) is an algorithm that is used to create pseudo-random outcomes in digital games, such as slots, video poker, and virtual table games.

There are many different ways in which random outcomes can be generated electronically. Most modern computer-based methods produce pseudo-random outcomes based on a seed number. The results are called pseudo-random because the software will always produce the same exact result if given the same seed number. True random results can only be generated based on physical processes (such as those happening on the quantum scale).

Most gambling games use pseudo-random number generation. For example, in slot machines, the random number generating algorithm works by combining the precise time the player presses the spin button with a pre-determined number sequence, which is tailored to produce the manufacturer’s desired hit rate and payout percentage.
