# The Mathematics Involved Behind Slot Casino Online: A Glimpse

Slots machines online have always been appealing to both new and experienced players because of the excitement they bring and the fact that you don’t have to use any strategy. While playing online slot games, all the player needs to do is click on the spin button and hope that the symbols will form a winning combination.

Slot machines make the use of a Random Number Generator (RNG) that ensures the outcome of the game is completely random. While the result of the spin is always random, the house achieves an edge in the game through the math, and this is how the casino makes money.

In this article, we’ll provide an insight into the mathematics involved behind slots casino online. Read on!

## Understanding coin-in and coin-out

Coin-in, simply speaking, is the total amount of coins or credits played in a slot machine. Let’s assume you choose a slot casino online and bet £1 per spin and do 50 spins. Your total coin-in is £50. Coin-in is not a count of how much coins you’ve wagered on the machine, but instead, a cumulative total of bets made. So, when you’re looking at coin-in on your reports with the casinos, it’s the calculation of the total amount of wagers made.

On the other hand, coin out is the total amount of coins paid out of the machine. Let’s use the same 50 spin example. Let’s say you received £35 inline hits and a £10 bonus. This would make for a coin-out of £45, as your total pays for those bets is that amount. Remember that coin-out is not what you cash out from the machine.

It’s possible to do all those levels of coin-in and out with a £10 bill, as you don’t need a £50 bill to place £1 wagers. You could win or lose through these 50 spins and cash out the amount that’s left after you’re done. Or you can switch from machine to machine, putting in £10 and doing 5 spins on each, which means that technically you put more than £50 into a machine even though you didn’t wager more than £50.

But online casinos care about the amount you bet and how much you get back from them in return, and this is the reason why coin-in and coin-out are the calculations of choice.

## The math behind the slots

In order to understand the math behind slots online, it’s important for you to understand the odds. For this, let’s take a simple example of heads and tails. The odds of you getting heads or tails with a flip of a coin is 50/50, which means that you’d expect to be even in the long-term.

For a casino to make a profit on this game, they’d use the math to create terms that benefit them. If it happens that you lose the bet, you lose the whole bet. But if you win, your payout will be 90 per cent of the full bet. In this scenario, you’ll end up losing 10 per cent of the total amount wagered over the long term. This way, the game created an edge to give the casino an advantage.

This is how the math behind slot casino online works. The payout of slot machines is calculated to be less than the odds of hitting a payout. In the long run, it’s not possible to beat an even-sum game or a slot machine that pays a percentage of the amount wagered.

## Looking at the most common slot

The most common online and mobile casino slot games feature three reels, with twenty symbols on each reel. In order to calculate the number of possible combinations of symbols on this type of slot casino online, you need to multiply the number of symbols on each reel by the number of stops on each of the remaining reels. As for the above example, this would be 20 x 20 x 20 = 8,000 slot symbol combinations.

Now, let’s say that the machine pays out a jackpot when three cherry symbols appear on the reels, and there’s only one cherry symbol on each reel. So, the probability of hitting the jackpot is 1/20 x 1/20 x 1/20 or simply put: one in 8,000.

As with the above example, you can calculate the probability of any combination of symbols hitting if you know the number of times each symbol appears on the reels.

All these things add up to how the math behind a slot machine works. It isn’t simple, but it’s important for you to know the fact behind the game when developing a strategy. As always, the more you know about a slot machine, the more winning chances you have.
