Modern casino Slots are controlled by computer software, and the winner percentages are pre-programmed into the game software.

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

Running synchronously with the RNG of the casino slot machine game is the pay out rate %.

The pay out percentage controls how much the one-armed bandit will payout, for example the pay per cent could be 90%, which means the one arm bandit will pay out 90% of all the wagers played, and the casino simply gets to keep 10 percent.

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

The profit percentages will vary between the various games and just a few of the notably famous casinos, like Golden Online Casino, which puts forth a payment of up to ninety five percent!

Therefore, in essence, the slot machine game takes all the currency played into it and pays it out to a handful of chosen winners. The casino only gets to keep a averagely small per cent of all the bets made.

The casino slot software controls each and every part of the machine, from the flashing lights to the turning of the reels.

When you hit spin on the one-armed bandit, a combination is put together by the RNG which associates with the pictures on the reel.
