Modern casino Slots are controlled by computer chips and software, and the win percentages are preprogrammed into the gaming software.
Casino Slots have Random # Generators which are continuously generating combinations, even when the game is not currently being played.
Running jointly with the Random Number Generator of the casino one-armed bandit is the payout percentage.
The payout percent controls just how much the slot machine game will pay, for e.g. the pay out percent may be ninety per cent, which means the slot machine will pay out ninety percent of all the bets played, and the casino gets to keep 10 per cent.
This doesn’t imply that every time you bet ten credits you will receive nine in return – where’s the fun … excitement in that? Instead, the casino slot machine just won’t payout for a while, and then suddenly hit a hot streak and you might hit a big jackpot.
The pay out %s will vary between the various games and some of the most popular casinos, for example Golden Online Casino, which gives a payout of up to 95 %!
Thus, in essence, the slot machine takes all the money played into it and pays it out to a couple of fortunate winners. The casino only gets to keep a averagely small percent of all the wagers allotted.
The casino slot software controls each part of the machine, from the flashing lights to the spinning of the reels.
When you hit spin on the slot machine game, a combination is put together by the RNG which is linked to the pictures on the reel.
