Modern casino Slots are controlled by computer chips and software, and the winner percentages are preprogrammed into the game software.
Casino slot games have RNGs that are continuously generating combinations, even when the machine is not active.
Running concurrently with the Random Number Generator of the casino slot machine is the pay out %.
The pay out % controls just how much the one-armed bandit will pay, for e.g. the pay percentage might be 90%, which means the slot machine game will payout ninety percent of all the wagers played, and the casino simply gets to keep 10 percent.
This is not to say that each time you bet 10 credits you will receive 9 in return – where’s the fun … excitement in that? Instead, the casino slot machine just will not payout for a bit, and then suddenly fire up a hot streak and you might catch the big grand prize.
The profit percentages will most likely vary between the different games and some of the most common casinos, like Golden Online Casino, which puts forth a pay out of up to 95 percent!
Hence, in essence, the slot machine takes all the $$$$$ played into it and pays it out to a couple of privileged winners. The casino only gets to keep a fairly small percentage of all the gambles placed.
The casino slot machine software controls each and every part of the machine, from the dazzling lights to the rolling of the reels.
When you hit spin on the slot machine, a combination is formed by the RNG which connects with the pictures on the reel.
