Modern casino slot machines are controlled by a computer, and the winning %s are pre-programmed into the game software.

Casino Slots have Random Number Generators which are constantly generating combos, even when the slot machine game is not being played.

Running side by side with the Random Number Generator of the casino slot machine game is the payout rate %.

The payout % controls how much the one-armed bandit will pay out, for example the pay per cent might be 90%, which means the slot machine game will payout 90% of all the wagers played, … the casino gets to keep ten per cent.

This does not mean that for every time you bet 10 credits you will receive 9 in return – where’s the fun and excitement in that? Instead, the casino slot machine game just won’t payout for a while, and then suddenly hit a hot streak and you might hit a big pot prize.

The pay off percentages usually will vary between the assorted games and just a few of the highly established casinos, e.g. Golden Online Casino, which hands out a pay out rate of up to 95 per cent!

Thus, in essence, the slot machine game takes all the dough played into it and pays it out to a number of privileged winners. The casino only gets to keep a basically minute percent of all the bets allocated.

The casino slot software controls each and every part of the machine, from the dazzling lights to the rotating 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.
