Is Roulette Rigged?

On a purple background showing a roulette wheel, a green gremlin with a wrench hides behind a red curtain, while a lady in 1950s style looks shocked at the roulette wheel.

Is roulette rigged? It’s the kind of question that sneaks in after a rough streak. While we’re not exactly the tin-foil hat type, when players start asking, you bet we’re going to chip in—we’ve seen Casablanca, too. And the question has crossed every player’s mind at least once.

So, what’s the deal? Are there magnets forcing the ball to land on 17? Is the dealer using a flick of the wrist to avoid your number? Is there a little green menace guiding the ball under the table? As long as you’re playing at a licensed casino, the answer is no, and we’ll explain why.

Do Land-Based Casinos Rig Roulette Wheels?

A lady croupier from the 1950s looks menacingly at a green gremlin holding a red magnet on a purple background, with the numbers of a roulette wheel visible.

Unless you only play roulette at home, and you’ve personally whipped out the spirit level and digital callipers, you’ve probably asked yourself at least once, “Is roulette fixed?” Or “Can roulette be rigged at a casino?”

The answer is, technically, yes…but would they actually do it? To be fair and balanced, we’ll explain how, theoretically, a casino could rig a roulette wheel, but also why they don’t.

Hidden Magnets: Debunked

This is a popular “rigged roulette wheel” conspiracy that gets tossed around like a salad. The idea is that casinos use a metal ball on the wheel and hidden magnets beneath it, causing the ball to land where they choose.

But there are some major problems with this. For one, heavier materials, like metal, can damage the roulette wheel’s track and pockets. This, in turn, can lead to an obviously biased wheel that needs to be replaced, and they’re not cheap. Also, if the casino can use a magnet to control the ball, then guess what? So can the players.

Even if the players weren’t playing with magnets in their pants, gamblers are betting on random numbers all the time. Magnet-using casinos would have no way of knowing which numbers to manipulate in advance. And if they did, players would quickly spot the pattern and bet on those.

Ball Tripping: Debunked

With ‘ball tripping’, someone (likely the croupier) will have to interfere with the ball’s path by knocking it off track (with everyone watching) or by releasing it in a way that influences where it lands.

Even if it were possible, they’d be tripping the ball from one random number to another random number. Not to mention the added major flaw of having actual casino staff in on the scheme, which just means more people who could spill the beans.

Skilled Croupiers: Debunked

There’s an urban legend that some croupiers are so talented they can land the ball wherever they want by the mere finesse of their spin. It sounds impressive, but it ain’t happenin’.

Roulette wheels are designed with diamond-shaped deflectors and other obstacles that create random bounces. That’s the boingy back and forth that gets you sweating before it lands.

But let’s just assume for a second that a croupier could pull this off under perfect conditions. They’d also have to immediately calculate which numbers have the least action, do it consistently under cameras, and hope nobody notices. That’s literally asking for “Now You See Me 2” level of collusion and trickery, and we can’t all be Mark Ruffalo.

Why Casinos Won’t Rig the Wheel

Perhaps the most important question to answer is not “Is roulette rigged?” but why a casino would want to rig it.

Even attempting to host a fixed roulette wheel is the casino daring to lose its license and face legal consequences while destroying its business reputation.

Plus, casinos don’t need to rig their roulette wheels to make money. That’s what the house edge is for. Thanks to the green pockets, it automatically rakes in 2.7% or 5.26%, depending on whether it’s European or American Roulette.

What is a Biased Roulette Wheel?

The inside of a roulette wheel is exposed, showing its gears. A male technician tweaks them with tools, while we see roulette numbers spinning just behind him.

Remember how we said casinos avoid metal roulette balls because they cause wear and tear? That mechanical damage is how you accidentally create roulette wheels with bias.

But what exactly are these “roulette biases”? Over time and thousands of spins, roulette wheels develop imperfections. They can be scratches, dents, or chips that can nudge the ball just enough to increase the chances of landing on specific numbers. None of this is intentional. It’s just what happens to mechanical objects over time.

And trust us, casinos already know. That’s why roulette wheels are regularly switched out, rotated, and inspected by independent gaming technicians. No legitimate casino is going to allow a biased roulette wheel to pass on the floor.

So, are roulette tables rigged when they develop these biases? Still no. But these biases bring us to our next interesting point.

Can Roulette Be Rigged Accidentally?

Not today, but that wasn’t always the case. There’s no better example than the 60s medical professor who used biased wheels to disprove one of the famous gambling quotes from Einstein: “No one can win at roulette unless he steals money from the table while the croupier isn’t looking.”

And to that, our professor likely said something along the lines of, “Oh, really, smarty pants? We’ll see about that.” (Not an official quote).

The Professor Who Beat the Roulette Wheel Through Observation

Dr. Richard Jarecki was your regular ol’ medical researcher with a knack for winning money on games like rummy and bridge with friends.

In the 60s, Jarecki developed a case of roulette obsession. And soon after, he observed a pattern that would fundamentally change how casinos operated.

Jarecki noticed casinos regularly replaced cards and dice but kept the same roulette wheels in service for years. He then realized the wheels eventually developed ‘wear and tear.’

So he did what any sensible person would do: hire a team of assistants and track thousands and thousands of spins (even up to 20,000 spins in a month) to pick up on patterns. Finally, it was time to put his money where his mouth was.

On his first day using his shiny new trick, Jarecki walked in with $100 and walked out with $5,000 (roughly $50K today). Not bad for your first day, eh?

Jarecki went on to bag today’s equivalent of over 8 million dollars between 1964 and 1969 with his…shall we say, unique roulette strategy.

But before you get any ideas, casinos learned their lesson, and Jarecki is partly the reason why roulette wheels nowadays are so heavily monitored.

Can Online Roulette Be Rigged?

With roulette numbers spinning in the background, a lady in a ‘50s style floral dress stares excitedly at a smartphone, while a green gremlin appears angry behind her, shaking his fist.

Nope. Not if you’re playing at a regulated online operator like Cafe Casino.

Legitimate operators use a Random Number Generator (RNG) that has been tested and verified by independent third parties.

RNG-based roulette is even more random than real table roulette. There are no hidden magnets or physical imperfections to nudge the ball in any which way. Plus, independent verifiers rule out the possibility of sketchy algorithms.

But if you choose to walk the path of illegal or unregulated online casinos with zero regulatory oversight and accountability, then you could run into a fixed roulette wheel. Stay out of back-alleyway casinos, and you’ll be fine.

We still have no opinion about most conspiracies, but it’s time to hang up that tin foil hat when it comes to rigged roulette wheels. Both land and online casinos go to great lengths to ensure their games are fair and unbiased. Play roulette at Cafe Casino, and confidently spin the wheel, knowing your results are as random as Elvis running a bait shop in rural Idaho. But here, the fairness is verified.
