A random number generator (RNG) is a computational(or physical) device designed to generate a sequence of numbers or symbols that lack any pattern.
RNG is the brain of the casino game, and as for online slot machines, they produce between 0 to 4 billion random numbers in general, and each number is linking to a specific slot icon or a feature.
So, how truly random is it?
It is the forever question for all of us.
When you load-up a casino games, you link into the gaming server of your casino. Casino servers have powerful microchips, and this microchips power the specific RNG software to produce a constant flow of random numbers 24/7 by the millisecond. Because random number generator keeps picking a number at incredible speeds, you need to literally click the button at exactly the right time to hit the big time jackpot.
The good random number generator will produce sequences that look nonrandom to the human eye and which also fail any statistical tests that we might expose it to.
If you flip enough coins, you will get sequences of coin flips that seen in isolation from the rest of the sequence don’t look random at all.
Even though it is impossible to predict when you have more chance to win, if you pick a good casino, you will end up with an average payouts of 95-98.5% in a long run.
