At the time, when online gaming was not started people used to play on slot machines which were very big in size. When those machines hit the jackpot they spit tokens and coins. The machines were operated by gears and leavers which are responsible for the randomness in the game. These gears and lives then used to power the rolling action of the reels. The reel combination of the machine was used to decide that whether the player had won or lost the game. However, as the man becomes familiar with the internet and algorithm in the slot games online casino slot machines were invented.

Instead of discussing about all the slot machines article focuses only on the working of online casino slot machines.

Random Number Generator

There is no doubt that the electrical and mechanical slot machines cleared the way to the development of the newer slot machines including the online casinos slot machines which use a computer chip to generate a random number on each spin.

The machines work on a different algorithm in comparison to the old slot machines. The computer chip which generates the random number is called as the Random Number Generator or RNG. The random number can be anything from single digit to a billion. This random number is then divided by numbers like 32, 64, 128, 256, and so on. The remainder of this division determines where the reels will stop. If the right reel combination is achieved on the active payline/paylines, then the player is declared to be the winner and exact winning amount is paid to the player.

Advantages of using RNG

One of the most important advantages of machines using random number generator in comparison to the traditional mechanical or electrical machines is unpredictability. As mentioned above the number that determines the winning combination is randomly generated in a fraction of seconds and this makes these machines more unpredictable. The RNG or Random Number Generator is constantly working and generating thousands of numbers in every millisecond or less, even when nobody is playing on the slot machine. And only because of the RNG only it is nearly impossible for the casino owner to rig the machine or pre-define any function in it. Another advantage of using these machines is that these machines are designed better than the traditional slot machines.
