Cheating RNGs

Is It Possible to Cheat RNGs on Online Slots?

Where there's gambling, there's cheating. One way or another. Now, Random Number Generators exist to keep online slots in check and prevent any type of fraudulent behaviour. However, there's certain info on RNGs that may explain how some people managed to 'cheat' slot machines. As this requires higher math and science, we won't be able to go into detail, but we'll try our best to explore RNGs and see how those daring few managed to bypass them.

Pseudo Random Number Generators

To start off, you may not know this but there are different types of Random Number Generators. The so-called Pseudo Random Number Generators don't need any external input and instead use an algorithm and seed numbers. What happens here is that new seed numbers are produced non-stop. From a non-scientist point of view, the last number or two produced are combined with a math operation—and voila!—you get yourself a random outcome.

"Pseudo Random Number Generators can, in theory, be hacked."

And again and again. However, these operat­ion­s—n­amely, addition, subtraction, multiplication, division and others—are always the same and will always end up churning the same output. That's why Pseudo Random Number Generators are not truly arbitrary and, more importantly, why they could theoretically be hacked.

Cheating and Beating RNGs

Now, don't freak out! Most of us aren't capable of cheating RNGs and our online gambling results are as clean and fair as can be. However, a selected few have managed to bypass them in the past. Let's name a couple.

You may remember the story of Ron Harris—does the Gods of Casino Gambling post ring any bells?—whose job used to be to find bugs on slot machines and ended up rigging said machines to churn out huge jackpots. On top of that, he came up with an entire program that managed to guess which numbers would come up through RNGs and raked in some serious bucks on keno games. The scheme eventually led him to prison, naturally, and today he's forbidden from entering any casino across Las Vegas.

"Norman Clem decided to track his wins and losses over the course of a year to see if the games were, in fact, rigged."

Then there was the 2008 incident when Norman Clem was playing craps at World Wide Wagering. He got the impression he'd losing a bit too much and, after this chilling realization, he set out to track his wins and losses over a whole year. He'd won a total of 856 times, which was only 27% and way too off from the standard deviation and the predicted 49%. He then did what every modern man would do—posted his findings online.

Just as well. Michael Shackleford, the Wizard of Odds himself, conducted a test of his own and found that BLR Software was indeed fixing their games to increase the house edge.

Online Casinos Tested for Fairness

Don't worry—these are just two examples out of thousands and thousands which say the exact opposite. The online casinos we feature are regularly tested, usually by impartial third parties that would never let them rig their RNGs.

"Online casinos approved by TST or GLI are safe."

So, when you see that an online or a mobile casino has been approved by Technical Systems Testing (TST) or Gaming Laboratories International (GLI), you'll know you are in a secure place. The results of their online and mobile slots have been proven random, so you can sit back, relax and spin those reels to your heart's content without any fear. If, on top of everything, the casino belongs to the exclusive group of Certified Casinos—you're as safe as can be!
