Modern casino Slots are controlled by a computer, and the win %s are preprogrammed into the software.
Casino slot machines have Random # Generators that are continuously generating combos, even when the slot machine is not currently being played.
Running synchronously with the RNG of the casino one-armed bandit is the payout rate percentage.
The pay out percent controls just how much the slot machine game will payout, for example the payout % might be ninety per cent, which means the slot machine will payout 90% of all the stakes played, … the casino only gets to keep 10 per cent.
This does not mean that every time you bet 10 credits you will receive 9 in return – where’s the fun and exhilaration in that? Instead, the casino one arm bandit will not payout for a bit, and then suddenly hit a hot streak and you might hit a big jackpot.
The profit percentages will definitely vary between the differing games and several of the highly acclaimed casinos, for e.g Golden Online Casino, which gives a payout rate of up to ninety-five percentage!
Therefore, in essence, the slot machine takes all the $$$$$ played into it and pays it out to several lucky winners. The casino only gets to keep a averagely minute percentage of all the wagers allotted.
The casino slot machine software controls each part of the machine, from the flashing lights to the rolling of the reels.
When you hit spin on the slot machine game, a combination is produced by the RNG which associates with the pictures on the reel.
