Modern casino Slots are controlled by computer software, and the winning percentages are pre-programmed into the software.
Casino Slots have Random Number Generators which are continuously generating combinations, even when the game is not active.
Running concurrently with the Random Number Generator of the casino one-armed bandit is the pay out percentage.
The pay out % controls how much the slot machine will pay out, for example the pay % could be 90%, which means the one arm bandit will pay out 90% of all the stakes played, … the casino will then get to keep 10 per cent.
This doesn’t mean that each time you bet 10 credits you will receive nine in return – where’s the fun … fascination in that? Instead, the casino one arm bandit will not pay out for a little while, and then suddenly start up a hot streak and you might draw the big jackpot.
The pay off %s will most likely vary between the a variety of games and just a few of the most famous casinos, for example Golden Online Casino, which gives a pay out rate of up to ninety five per cent!
So, in essence, the slot machine takes all the $$$$$ played into it and pays it out to a handful of lucky winners. The casino only gets to keep a considerably tiny percent of all the plays allotted.
The casino slot software controls each part of the machine, from the dazzling lights to the circulating of the reels.
When you hit spin on the one-armed bandit, a combination is set up by the RNG which corresponds to the pictures on the reel.
