What is RNG? 

RNG stands for Random Number Generator; it is software that runs slot machines by generating random numbers associated with certain symbols you can see on the reel. RNG uses a specially created algorithm that provides for different combinations of spin outcomes. The number is generated as you slip you coin into the slot or press the spin button. Some people think that “algorithm” means that the winning combinations are happening at the end of certain periods of time, and therefore, if you notice that frequency you can appear just on time for the next jackpot. However, it is not quite so.

It’s very common to compare that phenomenon with a magician’s hat with all the possible symbols. You can pick out some of them without looking, and pick out some more, but you always put them back. Which means, you can pull out exactly the same numbers, or never pull them out again.

All slot-machines today have these installed - which shatters the myth of any strategy possible. If it is quite possible at poker, for example, there is no way you can predict or make the machine give you the combination you need.
