Modern casino slot machine games are controlled by computer chips and software, and the winning percentages are preprogrammed into the computer software.
Casino Slots have Random Number Generators which are continually generating combinations, even when the slot machine is not active.
Running side by side with the Random Number Generator of the casino slot machine is the payout rate per cent.
The payout % controls just how much the slot machine will pay out, for example the pay percent could be 90%, which means the slot game will pay out ninety per cent of all the bets played, … the casino gets to keep ten per cent.
This doesn’t mean that for every time you bet ten credits you will receive nine in return – where’s the fun … exhilaration in that? Instead, the casino slot machine just won’t pay out for a while, and then suddenly start up a hot streak and you might draw the big pot prize.
The payoff percentages usually will vary between the different games and some of the extremely common casinos, for e.g Golden Online Casino, which gives a pay out of up to ninety five percentage!
Hence, in essence, the one-armed bandit takes all the funds played into it and pays it out to a number of fortunate winners. The casino only gets to keep a fairly low percent of all the plays made.
The casino slot software controls each and every part of the machine, from the flickering lights to the rotating of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which connects with the pictures on the reel.
