With better graphics, interactive bonus games and innovative designs, slot machines are becoming more and more advanced. Many game manufacturers compete with each other and want to offer the ultimate entertainment package. However, behind the amusing and charming exterior, the same mechanisms remain that always give the house an edge.
Nonetheless, 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 out, how we can improve our chances of winning and what still makes us enjoy playing with Mr Green so much .
The basics – slot machines leave everything to chance (ZZG)
Slot machines have no memory. You never know how much a player has won or lost and the outcome of previous spins does not affect the next. Every spin is unique and the result is always left to chance. This is ensured by a random number generator (ZZG) that is used in every slot machine (in English: ‘random number generator’ – RNG).
To bring this closer to you in a simple example, imagine a cube. The chance of hitting one of the six sides in a throw is identical for each and is 1/6. It does not matter which result occurred with the previous throw. The chances of hitting one of the six sides are always the same. Slot machines work in a similar way. However, there are many more than just six possible outcomes. Thousands of combinations are possible, but which symbol combination ultimately appears on the reels is still entirely up to chance.
However, unlike with the dice, the probabilities of the many possible combinations in a slot are 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 on average. For an illustration, let’s go back to our cube. Let’s say the 6 eyes on the dice indicate the highest payout of a slot, while the 1 stands for the smallest possible win. Instead of giving each side of the dice the same chance of 1/6 when thrown, we reprogram the dice so that the 6 only appears every twelfth time and the 1 appears every third time. If we roll the dice the outcome will still be determined randomly,
Let’s go one step further and illustrate this principle with our own invented 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.
|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 Sie der Tabelle entnehmen können, bietet unser Slot eine Wahrscheinlichkeit (Trefferhäufigkeit) von 1/100,000 (0.001%), um fünf Symbole des höchst-auszahlenden Symbols (Schatztruhe) zu erhalten, während die Wahrscheinlichkeit fünf gleiche Symbole irgendeiner Art zu treffen bei 1/13 (7.566%) liegt. So oder so ähnlich sieht das auch in echten Spielautomaten aus. Jeder Automat ist in der 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.
