Online slots on a smartphone

Algorithms are an essential component of casino games. Numbers, codes, and mathematical algorithms are the brains that run these slot machines. Typically, modern slot machines use a random number generator (RNG) which does not take memory into account while generating numbers. Let’s have a look at the details of these algorithms today.

What is a Random Number Generator?

One important necessity, especially given that casino gambling is remote in nature, is fair play. A random number generator, which is basically an algorithm developed by a computer that online casinos utilize to randomly assign the outcomes of a spin, satisfies this need for online slots.

It is the heart of the slot machine, generating random numbers in the range of one to several million at extremely rapid speeds. The RNG will record a series of numbers after you hit the button for a casino game to decide where the reels should stop.

Working of RNGs

Assume that you’re playing a three-reel slot machine. You select your bet and then rotate the reels by pressing a button. As soon as the button is clicked, the RNG will generate three numbers, the first of which will decide where the first reel will land, the second decides where the second will land, and so on. The RNG splits each of the three numbers based on a specific fixed value because it can generate numbers ranging from 1 to several million. Slot machines normally have fixed values of 32, 64, 128, 256, or 512.

What this means for slots is that every symbol on a particular reel has a value assigned to it. When the reels are spun, the RNG gives out distinct numbers at rapid speeds. As soon as the reels stop spinning, the set of numbers displayed on the screen at that moment will decide the symbols which will appear on the screen.

An important thing to consider is that each symbol on a reel is weighted uniquely. This implies that in any game which has 24 symbols for every reel, the likelihood of a symbol landing on any reel is 1 in 24 and is completely random as well. The chances of landing at a lower weighted symbol are more than that of a heavy weighted symbol.

Hardware Random Number Generators

When determining the results, hardware RNGs consider natural entropy or randomness. Because there are no repeating sets of numbers or algorithms to answer these, they are known as true RNGs, implying that they are completely random.

Hardware or True number generators are common in the gambling sector, and roulette is a notable example of this. The susceptibility of the ball to natural entropy, like the ambient temperature of the surroundings and how rough or smooth the material is, adds to the results as it rotates around the wheel.

Pseudo-Random Number Generators

Pseudo RNGs are not affected by natural entropy at all as opposed to RNGs. To make up for the absence of entropy and to incorporate randomness, these results are generated via an initial short value that passes through a complex equation.

Pseudo RNG games generate a random sequence with no distinct patterns using the key or the seed value. While seeds generated by computers are effective at providing random slot outcomes, the algorithms are determined by digital simulations, so the results aren’t truly random.

In this aspect, Pseudo RNG is a cost-effective approach for software suppliers and slot machine makers to recreate true random outcomes, and it is a crucial consideration when learning about slot machine algorithms in general.

Slot Machines’ Fixed Algorithms

RNGs are not really random, unlike their name. Algorithms are known to be fixed numbers, and they cannot be truly random. The probable outcomes of RNGs are deterministic, and the results of the landing of reels are not infinite in nature.

However, this does not imply that these RNGs can be manipulated or cheated.  The important thing to keep in mind is that slot systems do not have any memory. The computer cannot determine if the player has succeeded or lost or when they first began playing.

Mathematical algorithms determine all of these combinations. It’s critical to remember that game outcomes aren’t predetermined; rather, they’re the product of a series of events. A person could win two jackpots, one after the other, but this is not possible due to the program’s large number of possible configurations, each of which comprises 32 hex characters. This randomness of a casino game is what makes it so enjoyable.

Regulated and licensed casinos ensure that the RNGs used in slots are genuine and tested on a regular basis.

Third parties are also recruited to verify RNGs. For a particular RNG, all algorithms and formulas must verify that all results are unbiased. Internal quality checks are performed by sites such as and many others to prevent slot algorithm hacking.

The outcome of a slot machine algorithm is particularly difficult to monitor in a pattern due to the mixing of millions of sequences and seed numbers. Because of its intricacy, the outcomes are still unpredictable and random.

Final Verdict

The purpose of slot gaming comes down to having fun which is left to chance. It is this randomness and unpredictability of slot games that makes them so popular among casino enthusiasts. The intelligent algorithm enables slot machines to work effectively and be unbiased with randomly generated numbers and outcomes.
