A: It is the computer program that determines which symbols line up on the reels. Each random number generated corresponds to a reel combination. Whatever random number was generated the split second you hit the “spin” button (or pulled the handle) will result in the corresponding reel combinations that appear on your screen. The RNG doesn't care how much you bet, whether you bet one coin or maximum coins, whether you pulled the handle with your left hand or hit the spin button with your fist, whether it's your first play or last, whether you’ve been winning or losing, or whether you are playing with or without your slot-club card, and wearing your lucky charm won’t affect it either. After all, the Random Number Generator is a computer robot that just continually generates random numbers. If you happen to be the lucky person that plays the very split second the RNG generated a number that corresponds to the combination for the jackpot, you'll be the big winner.
