Understanding the Random Number Generator
In order to fully understand a slot machine you must first become familiar with how a slot machine functions. There are no special tricks and there is no magic behind where the reel stops. All slot machines are controlled by a Random Number Generator (RNG). Yes, there is a computer chip inside of each slot machine and it is what picks the numbers. Knowing when a slot machine is due to hit is not even an issue because you will not ever know.
The Random Number Generator
There is a microprocessor in each slot machine that runs a program which is called the Random Number Generator (RNG). It is constantly running even when no one is playing on the machine. The only way that this perpetual motion stops is if there is a loss of power. New numbers are generated every millisecond. Numbers range from zero into the billions and then are set into a specific numbers on the reels. So, the RNG decides what the numbers will be. Random Number Generators rely on algorithms, which is a formula that instructs which numbers will be generated. The numbers are so large that they surpass any human mathematical knowledge. While it can not be calculated, it can be checked to see if it is accurate. The Casino Control Board is who does the testing to ensure fair play to the players.
More simply put, each slot machine has a particular number of blank spaces on it. The computer world calls them physical stops. Depending on the age of the slot machine this number of spaces could be between 20-22. Let's assume for a second that there are 10 such spaces on a reel. This means that there would be about 1,000 combinations. Your chances of getting a three number combination are one in a thousand.
Fair Gaming Policy
Online casino games are always ran fairly. Always play at a licensed casino because they have their casinos audited for gambling fairness. This policy is mandated by licensing bodies to all gambling operators under their supervision. It is run this way so that there is no way to predict what combinations will pop up.
When you get a feel for what Random Number Generators are all about you can then begin to erase the thoughts of relying solely on luck to win. Your destiny is set before you ever push the button.
