How To Calculate Slot Machine Odds


Playing slots is definitely a game of chance, but there are some strategies and algorithms that can help in increasing the chances of success. Nonetheless, slots should be played for entertainment and not solely for the purpose of making money: nobody becomes a professional slot machine player, while in other games (like poker) you can make a living from it.

Though, when it comes to playing slots, there are things you can do in order to increase your chances of winning or reduce your chances of losing. You can click here to find a wide selection of online slot machines and try the strategies that we will mention down below.

For instance, in the process of calculating the percentage payout of a slot machine, you would be able to figure out how much money you are able to earn. Other methods include joining a slots club, effective bankroll management techniques, and lots more.

How The Slot Machine Works

Generally, all modern slot machines available now make use of a computer program referred to as a “random number generator” (RNG) to determine the relative outcome or result of the various number of spins. This machine has nothing else to do than constantly generate numbers.

Upon pushing the spin button, a number is selected on this generator machine, which then determines the outcome of the spin. It is so fast that it even happens long before the spinning stops.

Taking a more practical look at slot machines, the reels made available there are just there for the sake of it. This means that when you put money inside and press the spin button, all you get is the screen showing you whether you won or lost.

Therefore, the things that make the game actually interesting to play and enjoy are the sound effects, the bonus games, and the spinning reels. Those who don’t seem to fancy all these features of the slot machines, such as the music, artwork, and various other parts of the game, should not venture into it, as that is where the major rewards are. The possibility of being lucky enough to win a jackpot is an awesome reward, but try not to ignore the other parts of the game.

This software program (random number generator) works in such a way as to pay back a particular percentage of the cash paid over a particular time frame. However, the percentage we are referring to is always less than 100% for all slot machines.

If it were programmed to pay back more than 100 percent, the casino would definitely lose money. The main trick to playing is to find the best slot machine that offers the highest payout percentage, as most casinos are not willing to lose money.

What Are The Odds Of Winning On A Slot Machine?

Calculating the odds of a slot machine is somewhat easy. In cases where you have to deal with ten symbols on a three-reel machine accompanied by a limited paytable, then you have nothing to worry about, as it is just simple math.

However, there is more to it when it comes to dealing with video slots and electromechanical slot machines.
Probability refers to the chances of whether something will happen or not happen. It is also the math behind the calculation of that chance. Therefore, to understand the odds in relation to slot machines, you need to have a basic understanding of the mathematics behind probability.

In probability, the first thing to take note of is the fact that every event that occurs has a probability of between 0 and 1. In cases where there is no chance of the event ever happening, then the probability of such an event is 0, while in cases where there is always a chance of the event happening, then the probability of the event is 1. The number of ways an event will not occur versus the number of ways that event will occur is expressed as odds.

How Do You Calculate Your Odds Of Winning?

The difference between the chances of an event occurring versus the chances of the event not occurring is basically referred to as “odds”. By calculating your odds of winning, this will enable you to make wiser and smarter decisions when gambling.

These odds can be expressed as a ratio or as a percentage. Let’s say, for instance, you want to flip a coin. The likelihood of obtaining a head is 50%, which can be expressed as a ratio of 1:2.The number 1, which is the first part, shows the favorable outcome, that is, the chances of the event occurring. While number 2 shows the chances of the event not happening.

Now let’s consider the simple slot machine. It consists of 3 reels and a total of 3 rows with about 6 symbols. By multiplying 6 by 6 by 6, that equals 216. Now add the number of possible winning combinations that exist. In cases where there are 200 possible winning combinations, the odds of the game would be 200/216, which equals 92.5%.

Though, odds tend to become much more complicated when dealing with complex slots. Several other factors need to be taken into consideration, such as multipliers, jackpots, and account bonuses. For instance, the odds of winning a progressive jackpot get a lot easier and better as the jackpot tends to get larger as more people continue to play the slot and also bet maximum coins.

Also, it is important to note that odds and probability do not refer to the same thing. Probability on its own is the number of times an event will occur in a particular number of trials, meaning that it only lets you know the number of times you are most likely to win depending on the number of lever pulls available on the slot machine.

Probability is calculated by dividing the total number of lever pulls by the number of possible outcomes. For instance, if you play a slot machine about 100 times and there is a total possible outcome value of 200, then the probability of the game becomes 100 divided by 200, which equals 50 percent. In order to maximize your winning percentage while playing slots, you should focus on increasing both the odds and probability.


To summarize, wherever you decide on playing, ensure you make use of these guides in calculating your odds of winning on a slot machine.

By having in-depth knowledge about the probability and odds of the game, you will be able to become a more experienced and skilled player.

Remember to wager responsibly and be aware that although the odds and probabilities might help you to decipher your chances of winning, there is a margin of error and it will always end up depending on luck.
