Roulette is one of the most recognisable casino games, but it’s not unusual for players to wonder just how fair it really is. While every spin brings the possibility of a win, it also carries the chance of a loss—mainly due to the house edge built into the game.
Some players have raised concerns about whether casinos might make the odds even tougher by using magnets or tampered equipment. But are these worries grounded in reality?
In this blog post, we’ll explore what really goes on with roulette wheels and separate fact from fiction. Read on to learn more.
Do Casinos Use Magnets on The Roulette Tables?
In licensed casinos—whether online or land-based in the UK—the use of magnets or any kind of tampering is strictly prohibited. These venues are regulated by official gambling authorities, which carry out regular checks 
to ensure all games are run fairly and transparently.
A physical roulette wheel operates in a simple, mechanical way: the wheel spins in one direction while the dealer (or croupier) launches the ball in the opposite direction. Thanks to the wheel’s design and sloped track, the ball’s final position is completely unpredictable and cannot be influenced once it’s in motion.
Online roulette works slightly differently. Instead of a physical wheel, results are determined by Random Number Generators (RNGs). These systems are independently tested to ensure they produce fair, random outcomes that can’t be manipulated—by the casino or the player.
Why Casinos Don't Need To Use Rigged Roulette Wheels
Casinos rely on the house edge to maintain a consistent advantage over time—so there’s no need for any kind of tampering, such as magnets or rigged wheels. This built-in edge ensures the casino makes enough to cover its operating costs and remain profitable, all while keeping games fair and regulated.
Whether it’s French, European, or American roulette, each version comes with a slightly different house edge, but the underlying principle stays the same. With this natural advantage already in place, there’s little incentive for a licensed casino to risk its reputation or regulatory approval by using unfair methods.
Are Online Roulette Wheels Fixed?
Online roulette is subject to the same strict regulations as its land-based counterpart. Reputable sites—such as Wizard Slots—must be licensed by recognised authorities like the United Kingdom Gambling Commission (UKGC), which requires ongoing testing to ensure games are fair and operate as they should.
As mentioned earlier, online roulette relies on RNGs to produce unpredictable outcomes. These systems are regularly audited to make sure results can’t be manipulated. In a licensed and properly regulated environment, there’s no opportunity for the casino to fix the game or influence the outcome of a spin.
Can a Roulette Dealer Control The Ball?
Some players occasionally wonder whether experienced dealers might be able to influence where the roulette ball lands. While a skilled croupier can certainly keep the game running smoothly and professionally, they don’t have the ability to control the outcome of a spin.
As mentioned earlier, the way the ball bounces and moves along the sloped track makes its final position unpredictable. Once the ball is released, even the dealer has no way of knowing—or affecting—where it will end up.
Conclusion
Rumours about magnets or rigged roulette wheels can often overshadow how the game actually works. In reality, licensed casinos rely on regulated systems—such as RNGs for online games and clearly defined house edges—to ensure that roulette remains fair and consistent.
If you choose to play, it’s important to stay within your limits and follow responsible gambling guidelines. Taking a balanced approach can help keep the experience enjoyable and in perspective.
