Modern casino slot machine games are controlled by a computer, and the winning %s are pre-programmed into the software.
Casino slot machines have Random Number Generators which are ceaselessly generating combinations, even when the machine is not being played.
Running simultaneously with the random # generator of the casino one-armed bandit is the payout rate per cent.
The payout percent controls how much the slot machine game will pay out, for eg the payout percentage could be ninety percent, meaning the slot game will pay 90% of all the stakes played, and the casino gets to keep ten percent.
This does not imply that for every time you bet ten credits you will receive 9 in return – where’s the fun and exhilaration in that? Instead, the casino slot just will not payout for a little while, and then suddenly start up a hot streak and you might hit a big grand prize.
The pay out %s will definitely vary between the various games and a handful of the notably popular casinos, like Golden Online Casino, which gives a pay out rate of up to 95 %!
Thus, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to a handful of lucky winners. The casino only gets to keep a averagely indistinct % of all the wagers placed.
The casino slot machine software controls every single part of the machine, from the dazzling lights to the spinning of the reels.
When you hit spin on the slot machine, a combination is put together by the RNG which is linked to the pictures on the reel.
