Virtual Slot Machines - Random Number Generator
The reel spins on all slot machines are controlled by a computer chip
embedded within the internal components of the slot machine at land-based
casinos or a computer program at virtual casinos called a Random Number
Generator (RNG). It makes absolutely no difference if you pull the
handle, push the button, or insert one or five coins - The RNG will
control the entire reel outcome. When a casino orders a slot machine,
it tells the manufacturer what percentage it wants that specific machine
to pay back, and that amount is then programmed into the RNG. The
casino can change the payback percentage, but in order to do so, it
must go back to the manufacturer to get a new RNG programmed with
the new amount. In addition, paperwork must be filed with the state
commission, listing serial numbers, dates, and lots of other information.
For these reasons, most casinos seldom change their payback percentages.
RNG's are programmed to produce higher numbers of stops, reels, and
symbols on the progressive jackpot machines than on the regular or
non-progressive machines. Because of this, you're better off concentrating
on a regular machine.
