Modern casino slot machines are controlled by computer software, and the win percentages are pre-programmed into the game software.
Casino slot games have Random # Generators which are continuously generating combos, even when the slot machine is not being played.
Running collectively with the Random Number Generator of the casino slot machine is the pay out percent.
The payout per cent controls how much the slot machine will pay out, for e.g. the pay percentage might be ninety per cent, meaning the slot machine will payout ninety percent of all the wagers played, and the casino will then get to keep 10%.
This does not imply that each time you bet 10 credits you will receive nine in return – where is the fun … excitement in that? Instead, the casino slot machine won’t pay out for a little while, and then suddenly hit a hot streak and you might draw the big jackpot prize.
The profit percentages will very likely vary between the various games and a couple of the most established casinos, e.g. Golden Online Casino, which puts forth a pay out of up to 95 %!
Thus, in essence, the slot machine takes all the dough played into it and pays it out to several privileged winners. The casino only gets to keep a considerably petite % of all the plays allocated.
The casino slot software controls each part of the machine, from the flickering lights to the revolving of the reels.
When you hit spin on the one-armed bandit, a combination is generated by the RNG which corresponds to the pictures on the reel.
