Modern casino slot machines are controlled by computer software, and the win %s are preprogrammed into the game software.
Casino slot machines have Random Number Generators that are endlessly generating combos, even when the slot machine game is not currently being played.
Running simultaneously with the random # generator of the casino one-armed bandit is the payout rate percentage.
The payout percent controls how much the slot machine game will payout, for eg the pay percent could be ninety per cent, meaning the one arm bandit will pay out ninety percent of all the wagers played, … the casino only gets to keep 10 per cent.
This doesn’t imply that every time you bet ten credits you will receive 9 in return – where is the fun and fascination in that? Instead, the casino slot machine game just won’t payout for a while, and then suddenly hit a hot streak and you might catch the big grand prize.
The pay off percentages usually will vary between the assorted games and several of the very established casinos, for e.g Golden Online Casino, which provides a payment of up to ninety-five percentage!
So, in essence, the slot machine game takes all the funds played into it and pays it out to a couple of fortunate winners. The casino only gets to keep a considerably indistinct percentage of all the stakes put out.
The casino slot machine software controls each part of the machine, from the blinking lights to the revolving of the reels.
When you hit spin on the slot machine game, a combination is generated by the RNG which relates to the pictures on the reel.
