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