Modern casino Slots are controlled by computer chips and software, and the win percentages are preprogrammed into the software.
Casino slot games have Random Number Generators which are eternally generating combinations, even when the slot machine game is not currently being played.
Running concurrently with the Random Number Generator of the casino one-armed bandit is the payout per cent.
The payout % controls just how much the slot machine will payout, for eg the pay percentage could be 90%, meaning the slot machine will payout ninety per cent of all the wagers played, and the casino simply gets to keep ten per cent.
This doesn’t imply that for every time you bet 10 credits you will receive nine in return – where’s the fun and fascination in that? Instead, the casino slot just will not pay out for a bit, and then suddenly go on a hot streak and you might draw the big grand prize.
The payout %s will tend to vary between the a variety of games and a couple of the very common casinos, for e.g Golden Online Casino, which provides a pay out rate of up to 95 percent!
Hence, in essence, the one-armed bandit takes all the $$$$$ played into it and pays it out to a number of lucky winners. The casino only gets to keep a generally small per cent of all the plays allotted.
The casino slot software controls each part of the machine, from the flashing lights to the turning of the reels.
When you hit spin on the slot machine game, a combination is developed by the RNG which is linked to the pictures on the reel.
