Random Number Generators (RNG) for Online Casino Games
If you are planning to play at an Online Casino then it is crucial that you understand how Random Number Generators work.
Winning or losing is not based on magic, behind every sequence of numbers presented is a random number generator.
It is a technology that feeds numbers seemingly at random.
Random number generation is often referred to as RNG in the gambling industry.
Another term you need to be familiar with to understand this concept is Return to Player (RTP)
When casino games without dealers are developed they are assigned an RTP. We will use slots as an example in this article to explain how random number generators work. Slots normally have a return to player ranging between 92%-96%.
A very simplified “win or lose” formula for online casino slots looks like this:
BET ∗ RNG ∗ RTP = Outcome.
