Online slot machine games are more than meets the eye. They are indeed based on chance – or luck – but behind the virtual reels, there are sophisticated algorithms to make sure that the chance you’re playing against is as pure as chance can be.
This post intends to explain the main principles that keep online slot games a fair game. They are listed and elaborated as follows:
Random Number Generator
A random number generator, or RNG, works on an unidentifiable algorithm which makes it impossible to predict the outcomes of players’ bets. Many regulators require online casino operators to integrate RNG systems that are registered by an independent third party.
The organization responsible for certifying the random number generator (RNG) will analyze the source code and perform statistical tests to ensure that the RNG behaves in a random manner. This program generates numbers corresponding to the symbols on a slot machine wheel and thus decides the result of a game.
An RNG system constantly selects random numbers every millisecond — from 0 up to about 4 billion. These numbers are then associated with a position on the wheel of the Slot Machine via a table of correspondence.
Return to Player
Return to Player or RTP is a method of protecting users from losing too much in their slot machine bets. It is basically a term casino use to define the percentage of wagered money a slot machine will give back to the player. For instance, if a casino offers an RTP of 90%, and you have — over time — placed hundred of $1 bets, you can expect to get back 90% of the betted funds, i.e. $90.
RTP is somewhat mirrored to house advantage. So a 90% RTP will certainly mean a 10% house advantage.
