Modern casino slot machines are controlled by computer chips and software, and the winner percentages are preprogrammed into the computer software.
Casino one armed bandits have Random Number Generators which are eternally generating combos, even when the game is not being played.
Running in unison with the Random Number Generator of the casino slot machine is the payout percent.
The payout percent controls how much the slot machine will payout, for e.g. the payout percentage may be 90%, meaning the slot game will pay out ninety per cent of all the stakes played, and the casino simply gets to keep ten per cent.
This is not to say that each time you bet ten credits you will receive 9 in return – where’s the fun and fascination in that? Instead, the casino slot machine game just will not pay out for a while, and then suddenly fire up a hot streak and you might hit a big top prize.
The payoff percentages usually will vary between the different games and a handful of the very popular casinos, like Golden Online Casino, which offers a cash payment of up to ninety-five per cent!
As a result, in essence, the one-armed bandit takes all the cash played into it and pays it out to some chosen winners. The casino only gets to keep a relatively indistinct per cent of all the bets allotted.
The casino slot software controls each part of the machine, from the flashing lights to the circulating of the reels.
When you hit spin on the slot machine game, a combination is formed by the RNG which corresponds to the pictures on the reel.
