Each of us has encountered a slot machine, whether it was in a pub, a slot machine arcade, or a casino. You know you can winor lose, and that is about all you know. But what should you definitely know before playing?
Who invented the slot machine?
The first mechanical slot machine was pieced together in 1899, in San Francisco, by a car mechanic named Charles Fay, the grandfather of all slot machines today. At that time, when you hit the jackpot - the three bells of freedom - you won a whopping 50 cents. Slots back then had 3 columns with 10 symbols, so you had a 1:1000 chance of winning the jackpot. Since then, they have come a long way and today they are operating on a totally different principle.
How did slots change?
The most important change is that mechanical cylinders were replaced by a computer, and a visual display of the game outcome is charged by small power-operated cylinders, or directly by a classic screen. Slots can also be played online and so, pulling the lever has changed to clicking a mouse, or hitting a button. The element of chance, originally created by mechanical stops, was replaced by a random number generator. In fact, RNG randomly decides whether you win or lose. How does this work?
RNG in the game
Some players think that a slot machine repeats the same cycle over and over again. Mistake! Thanks to RNG, it creates new number combinations, which it assigns to symbols on cylinders. This happens the moment you click the "SPIN" button, so even a slot itself does not know if you will win or lose beforehand. Do you believe that the previous spin has an effect on the next one? It does not at all. The outcome of the previous spin in no way effects the outcome of the next one.
A slot machine does not have a memory
Really, it remembers nothing. Nothing at all. Even if you win 2000€, mathematically, you have the same chance of winning again in the next spin.
Can you somehow influence the outcome of a spin? Theoretically, yes. Each milisecond, the slot machine generates new random numbers, so the outcome depends on the exact milisecond in which you hit the spin button. But in practice, you don´t know which numbers will be generated nor which outcome will be recorded, so the real outcome depends solely on your luck.
How does RNG work in practice?
Every slot game has its set of reels. Most commonly, they have three or five reels which, after hitting the spin button, spin and stop. Slots must also have rules that determine if you have won and if so, how much. Your win is decided by the symbols on the reels. Many games have special bonuses - very often they are free spins, where there is no credit deducted by spinning, and even though you play for free, you can win real money. On what does the position of the reel stop depend? This decides RNG which, based on a randomly created number, determines the orientation of reels and therefore whether you won or not. From the reels definition (commonly unpublished), from the rules for winnings evaluation and from other special rules, you are able to find out about two very interesting characteristcs - a payout ratio and a variance. What exactly do they mean?
