The set of numbers that are thrown up when the reels stop spinning determine the symbols that appear on your computer screen at that point in time. When you spin the reels the RNG algorithm throws up unique numbers, at the speed of hundreds per second. What this means for Slots: Each symbol on a reel has a specific value assigned to it. It could be processes that are running, the specific pattern to a mouse click, a specific set of keystrokes, or even the computer’s clock. The seed value is derived from any one of a number of repetitive actions or operations happening in the computer. This is only natural because for something to execute repeatedly there has to be a beginning: that is the seed value. How the RNG Works: The software sets up the algorithm with a seed value.

This is what it means: if you know the state of the PRNG you can reproduce the random number sequence generated.

Pseudo Random Number Generator (PRNG): This type of RNG generates numbers that only look random.

That is why they are also called True Random Number Generators (TRNG). They are truly random because you don’t even have a repeated set of numbers or a set algorithm to crack them.

They are not even computed values that are obtained from an algorithm that executes repeatedly.

Hardware Random Number Generator (HRNG): This type of RNG genuinely generates random numbers.

It does this by generating a sequence of numbers, each number corresponding to a symbol on the reels, which one cannot predict by any means other than by chance. The random number generator is an algorithm generated by a computer that online casinos use to randomize the results of a spin. Online casinos fulfill this requirement for online slots by using a random number generator (RNG). We will first discuss about the RNG and then move on to the science behind the visual aesthetics.Įspecially because of the remote nature of online casino gambling, one critical requirement is fair gaming. On this page we take a look at the science behind online slots and how it all works. The entire process is simple for a player, but there is a huge amount of science involved in creating the entire experience: right from the way a slot looks and feels to the way you are guaranteed a completely random outcome for every spin with the random number generator (RNG) and, even further, the psychological aspect that makes slots so successful. You win if you hit a winning combination.

The reels spin away and stop at a point in time. You place your bets and hit the Spin button. Online slots are fun to play and are among the most popular games at online casinos.
