Random Number Generator

A Random Number Generator is a piece of software that creates random numbers. Online casinos are required to use a Random Number Generator in their games. It is strictly controlled by governments to ensure that they comply with this.

In online slots a Random Number Generator determines when the reels come to a stop, in virtual table games a Random Number Generator determines which cards are dealt and in live casino games the multipliers are determined by means of a Random Number Generator.

Volatility / Variance

For low volatility / variance casino games, the emphasis is mainly on winning lower amounts more often. For a high vlatility / variance, the reverse is true. So with an extremely high volatility / variance slot machine, you won’t win often, but when you do win, it will be a large amount.

An example of a very volatile casino game is XXXtreme Lightning Roulette.
