Slot machines use maths to operate, so why can’t you use mathematics too beat them? Let’s fight fire with fire. Find below a math based approach to playing online slots at sites such as

Understanding the mathematics behind online slot games is invaluable in helping players choose the best machine. So let’s start by explaining how mathematics is used to operate slot machines.

Slots mathematics

The outcome of each spin on a slot machine is determined by a Random Number Generator (RNG). These Random Number Generators use mathematical formulas to generate random numbers, which correspond to the symbols on any given slot. If the random numbers generated correspond to a winning symbol combination, you win.

Calculating probabilities playing slots games

Probability refers to the likelihood of players winning at a slot machine. In order to calculate the probability of a specific slot, you need to know what a specific winning combination pays, as well as the probability of landing that combination.

How much any given combination pays out is usually listed in the paytable, but how do you calculate the probability of landing that combination? Easy. Just calculate the amount of stops in that slot. Let’s use a simple example. Let’s say that a slot contains 3 reels, with 5 symbols on each reel. To calculate the number of possible combinations on this machine, just multiply the number of symbols on each reel, by the number of stops on each reel. So this would be 5 x 5 x 5 = 125 possible winning combinations. If the jackpot in this slot pays out only for three cherries across the reels, and only one cherry occurs per reel, the calculation would be as follows: 1/5 x 1/5 x1/5 which equals a 0.008% chance at hitting the jackpot.

It is thus possible to calculate the probability of landing any combination as long as you know the number of times that each symbol appears on every reel, which is not information usually shared by online slots. Modern machines also come with many different numbers of reels and winning combinations, which could make it difficult to calculate its probability.

It is quite possible to calculate the probabilities of a simple and traditional slot machine. However, with modern slots it would be pretty much impossible, as slots can have as many as ten reels and 200 stops.

RTP percentages for online slot games

Return to Player percentages (RTP) refers to the overall percentage of total wagers that a video slot game will pay out back to players over a period of time. Each online slot has a Return to Player percentage. For example, if a slot has an RTP of 98%, that means that for every dollar you bet, you will get back 98 cents. So to increase you odds of winning, you would want to choose the slot machines with the highest RTP rates, preferably 90+.
These are just a few of the ways in which you can use maths to choose the right online slot and improve your chances at winning.
