With better graphics, interactive bonus games and innovative designs, the slot machines in the online casino are becoming more and more sophisticated. Many game manufacturers compete with each other and want to offer the ultimate entertainment package. Behind the amusing and charming exterior, however, there are almost always the same mechanisms that give the house an advantage. Even so, we love to play slot machines in the hope of being one of the lucky winners.

In the following article we take a closer look at the mechanics of a slot machine, why we lose in the long run, how we can improve our chances of winning and why we still enjoy playing so much.

The basics – slot machines leave everything to chance (ZZG)

Slot machines have no memory. You never know, at any point in time, how many times a player has won or lost. The result of previous games has no influence on the next. No spin depends on the other, each one is completely arbitrary. The result is always a coincidence. This is ensured by a random number generator (ZZG) that is used in every slot machine (in English: ‘random number generator’ – RNG).

A simple example: Imagine a cube. The chance of hitting one of the six sides in a throw is the same for each side and is 1/6. It does not matter which result occurred with the previous throw. The chances of hitting a certain side are always the same for everyone. Slot machines work in a similar way. But there are far more than just six conceivable outcomes. Thousands of combinations are possible. But which symbol combination appears on the reels at the end is always pure coincidence.

However, unlike with the dice, the probability of the many possible combinations in a slot is not the same for all. This is ensured by the hit frequency (in English: ‘hit frequency’), which specifies how often a certain symbol combination appears on the reels. For an illustration, let’s go back to our cube. Let us assume that the six eyes on the dice indicate the highest payout of a slot, while the one stands for the smallest possible win. Instead of giving each side of the dice the same chance of 1/6 when thrown, the game manufacturers program the dice so that on average the six now only appears every twelfth time and the one every third time. If we roll the dice, the outcome of the next roll is still determined randomly,

Let’s go one step further and clarify this principle with our own, fictitious slot machine. We call it “The Happy Aquarium” and just give it five different symbols to keep it as simple as possible: treasure chest, golden fish, purple fish, yellow fish and red fish.

combination Payout Hit frequency
Five treasure chests 2500 0.001%
Five golden fish 1000 0.015%
Five purple fish 400 0.05%
Five yellow fish 50 0.5%
Five red fish 5 7%
All in all 3955 7,566%

Wie die Tabelle zeigt, bietet unser Slot eine Wahrscheinlichkeit (Trefferhäufigkeit) von 1/100.000 (0,001%), die fünf Symbole mit der höchsten Auszahlung (Schatztruhe) zu erhalten, während die Wahrscheinlichkeit, fünf andere gleiche Symbole zu treffen, bei 1/13 (7.566%) liegt. So ähnlich sieht das auch in echten Spielautomaten aus. Jeder Automat ist in dieser Hinsicht anders und unterscheidet sich bei Auszahlungen und Trefferhäufigkeit. In der Regel bewegt sich die Trefferhäufigkeit bei Slots um die 40%, um irgendeine Gewinnkombination zu erhalten.

Since chance is the determining factor in slot machines, we always have a chance of making a profit on slot machines. But the house always has an advantage over the player. The more he plays, the higher the chance for the house. In the long run, the player loses – always.

The reason for this is due to the programming of the slots, which always gives the house an advantage. In addition to the hit frequency, which specifies how often a certain winning result occurs, there is also the so-called return for the player, in English “return to player”, or RTP for short. This value indicates how much money a slot pays out to players in the long run.

Loosing on slots

The return for the player is always less than 100%. An RTP of 100% or more would mean the house is not making a profit or is even losing money. With online slots, the return to the player is more usually between 92% and 97%. Suppose we are playing a slot with an RTP of 95%. This means that on average the slot machine pays back 95% of the stakes for each game. With a stake of € 100, – we would get 95% back and lose € 5, -.

Since chance reigns, in reality it is very seldom the case that the player gets back or loses exactly this amount. Instead, you could be very lucky with your first € 100 bet and turn it into € 400. But maybe you are unlucky and your money shrinks to € 20. In the long term, however, the loss will level off at around € 5 per € 100 stake.

Wie viel zahlen Spielautomaten zurück?

How much you win and lose in the long run is always decided by the return for the player. The return depends on the probabilities for each outcome and their payouts.

Let’s take another look at our invented slot machine and this time add the income for the player. First we have to calculate the RTP for each possible result. All you have to do is multiply the hit frequency of a combination with its payout. To get the total RTP value, all you have to do is add up the individual income for the player.

combination Payout Hit frequency Return to player (RTP)
Five treasure chests 2500 0.001% 2.5%
Five golden fish 1000 0.015% 15%
Five purple fish 400 0.05% 20%
Five yellow fish 50 0.5% 25%
Five red fish 5 7% 35%
All in all 3955 7,566% 97.5%

In our example slot, we are paying players 97.5% over the long term. That would be a very cheap RTP. With our example, please keep in mind that we have simplified it extremely. In real slot machines there are far more symbols and possible symbol combinations. In order to calculate the RTP of a real slot yourself, one would have to have the probabilities for every possible outcome. However, this is never the case, the number of possible results is far too large. Fortunately, we don’t need that either. The income for the players is specified by the game manufacturer and can be looked up at any time in the slot machine information.

Warum Spielautomaten spielen – ist es möglich zu gewinnen?

If we always lose in the long run, why the hell are we even playing? The main reason for this, of course, is entertainment. Playing is not an investment in the future, any more than going to the cinema or a weekend in the spa. It doesn’t have to be, because it is fun and also offers excitement and thrills, which many of us lack in everyday life.

Since chance is always the deciding factor, big wins are of course possible, although the probability is small. If we play jackpot slots where a single spin can turn your whole life upside down, we can actually become a millionaire in one fell swoop. Then we probably beat the house forever and – for all of our lives – made a huge profit on the slot machine. Of course, the chances of winning a life-changing jackpot are very slim. But there is a chance, and the fact is, that someone will actually win. This is what makes jackpot slots nerve-wracking games.

betting budget management

Although we cannot influence the RTP of a slot machine, we have the opportunity to improve our chances with good bonus offers. This is due to the bonus funds that we have won and that are available to us in such promotions. They allow us to improve our chances of a positive outcome and increase our chances of winning when luck is on our side.

In summary, slot machines not only add entertainment and make our lives more exciting and exciting. They also offer a chance to win big with sums of money that can change your whole life. Although there is a chance for the individual, one should always keep in mind that in the long run only the house wins and the player loses.
