Modern casino slot machine games are controlled by computer software, and the win %s are preprogrammed into the game software.

Casino slot machine games have RNGs that are ceaselessly generating combinations, even when the slot machine is not currently being played.

Running simultaneously with the Random Number Generator of the casino one-armed bandit is the payout per cent.

The pay out per cent controls how much the slot machine game will pay, for e.g. the payout per cent might be 90%, which means the slot machine will payout ninety percent of all the wagers played, … the casino simply gets to keep 10 percent.

This doesn’t imply that each and every time you bet ten credits you will receive 9 in return – where’s the fun and fascination in that? Instead, the casino slot machine game just won’t payout for a bit, and then suddenly start up a hot streak and you might draw the big pot prize.

The pay off percentages will vary between the various games and some of the most popular casinos, such as Golden Online Casino, which tenders a payout of up to 95 %!

Thus, in essence, the slot machine takes all the funds played into it and pays it out to some privileged winners. The casino only gets to keep a fairly petite % of all the plays allotted.

The casino slot machine software controls every part of the machine, from the flickering lights to the rolling of the reels.

When you hit spin on the slot machine game, a combination is set up by the RNG which is linked to the pictures on the reel.
