Here is a kicker for those out of the gaming loop. All reel-spinning games, whether at land-based establishments or on the internet, use virtually an identical slot machine code to determine round outcomes.

The code in question is an algorithm called a random number generator (RNG), software that arbitrarily produces unpredictable figures. Hence, slot machine probability mathematics is a thing, as it is the chance element in spinning reels on a quest for real money prizes.

In the subheadings below, we elaborate on how casinos use math to make money when you play slots while also answering – precisely, how does slot machine math work?

How Random Number Generation Creates Slot Combos

Is there an algorithm for slots? Yes, as touched above, it gets called a random number generator. For the not tech-savvy readers, an algorithm is an automated procedure that follows a list of instructions, step by step, to conduct a specific action.

In this case, a random number generator’s job is what its name suggests. It is a series of steps used to generate numbers randomly. The software does this task by taking a figure called the seed, then running it through a set of complex mathematical formulas. That entails this initial number getting multiplied, divided, added, subtracted, and so on, many times over to create a new one.

The reel-spinning game will then take this newly created number and correspond it to a potential symbol combination, one of the millions possible, relaying it on its reel grid. Depending on the rules in play, that combo will be a winning or losing one.

So, if someone asks you – what is the math behind slots? You can give them this explanation. But, know that the RNGs used by gambling games are pseudo-random number generators because they use a predictable seed, meaning their number generation process is not entirely indiscriminate.

Online Slot Game Specs Defined

The two main specs of any reel-spinner that interest most players are variance and return-to-player. These get worked into a random number generator, impacting the type of numbers it produces and how frequently winning ones come up. Please remember that these specs are only valid for millions of spins. Therefore, no one can predict when specific combos will appear, no matter how long they study a title’s behavior.

Return-to-player (RTP) is a spec that defines how much of the money bet on a given game that product will pay back to its players. The second most vital characteristic of all real money slots online is variance. That is an economics term that measures variability from the average.

How Game Specifications Work Together

Essentially, return-to-player is a setting described using a percentage that informs gamblers how much from every $100 wagered a game will return as prizes. For example, a title with an RTP of 90% will keep $10 of every $100 bet, and the rest shall get redistributed to future players as rewards.

The degree to which a game will yield prizes and in what size gets governed by its variance. A low one means that a reel-spinner will churn out small rewards regularly, while a high variance setting will cause a gaming product to produce primarily substantial wins but rarely.

In correlation with each other, RTP and variance define slot machine statistics. Typically, a high RTP game will have low variance, and a high variance one will feature a lower RTP setting.

Regulators Mandate That Specific Slot Math Gets Used

Gaming product providers and casino operators cannot set any math model to their games’ random number generators. Their licensors/regulators obligate them to implement ones that will ensure that players win some of the time.

In the US brick-and-mortar sector, bodies like the Nevada Gaming Commission and New Jersey’s Division of Gaming Enforcement mandate that no gambling establishment features slots with an RTP below 75%. Online regulators usually list a minimum percentage of 85% for all RNG-powered products.

Online Slot Bonus Math

Bonuses are the backbone of the gambling industry. However, they are not stipulation free, as casinos are not in the business of giving away free money. Therefore, operators design their promotions to force gamblers to wager significant amounts before they can reap the benefits of a casino deal.

The dreaded wagering requirement (rollover) is likely the most famous bonus condition. It is a multiplier that states how many times a gambler must wager his deposited sum before withdrawing any promo winnings. A typical bonus rollover is 35x. Nevertheless, the more free-play funds a bonus provides, the higher this multiplier will be, directly ensuring casino profitability.

Final Thoughts

The information above only scratches the tip of the iceberg concerning getting the math of online slots explained 100%. But it’s a decent foundation to get parties interested in this topic curious enough to perform a deeper dive into it.
