Do online casinos adjust roulette odds based on their bets? The reality depends on whether you’re playing live dealer or RNG roulette.

Some roulette online casinos use unfair practices, but knowing the signs can help avoid rigged games. This guide breaks down dynamic RTP, how casinos might tweak odds, and the safest roulette options for real-money players.

 

Can Online Casinos Adjust Roulette Odds?

Online casinos cannot legally adjust roulette odds in licensed games, but the reality is more complex. In RNG roulette, they code the RTP into the software.

Live dealer roulette follows the same physics as a land-based wheel. However, not all casinos play fair.

Is Roulette RTP Dynamic or Fixed?

In a fair game, the RTP of roulette doesn’t change. European roulette has a 97.3% RTP, while American roulette’s is 94.74% due to double zero. The odds are standard across legitimate casinos, and changes require regulatory approval.

However, some shady operators introduce dynamic RTP. In other words, the payout percentage changes based on player behavior. Some provably unfair casinos tweak their games to lower payouts when players win too often.

Do Casinos Control RTP in Live and RNG Games?

Casinos do not manually adjust RTP in RNG roulette from reputable providers. Certain rogue operators tweak game algorithms to reduce high-win streaks or delay big payouts.

🎰 Live Dealer Roulette

Live roulette should be impossible to rig since it involves a real wheel and dealer. Casinos still have ways to influence results.

Some players reported dealers spinning the ball favoring certain sections, while others suspect magnetized wheels in rogue live games.

A prime example is Playtech’s “Express Roulette”, which faced backlash for an unusual pattern of biased spins.

🏆 Licensed vs. Unregulated Casinos – Who Sets the Rules?

✅ Licensed Casinos

Regulated casinos cannot adjust RTP unfairly. Every roulette game must pass independent audits by firms like eCOGRA, iTech Labs, and GLI.

Casinos must publish game RTP and cannot tweak odds unless they update software and disclose changes.

⚠️ Unregulated Casinos

Some unlicensed sites alter their roulette games. Fake software mimicked real games, but the outcomes weren’t fair.

🎭 Instances Where Casinos Cheated

🎥 BetOnline Live Dealer Roulette Scam (2017)

Players caught a dealer manipulating the ball to avoid high-paying bets. The video went viral, exposing the scam.

🎭 Fake NetEnt Roulette (2019)

Several unlicensed casinos used a counterfeit version of NetEnt’s roulette. The outcomes were rigged.

📉 Rigged RNG Roulette at Super Casino (2014)

Players noticed a biased number distribution favoring the house. The UKGC later imposed stricter fairness rules.

RNG Roulette vs Live Dealer: Which One Is Safer?

Choosing between RNG roulette and live dealer roulette comes down to fairness, transparency, and trust. While both game types claim to be random, one offers more protection against manipulation.

🎲 How RNG Roulette Works – Can Casinos Manipulate It?

RNG roulette is a digital version where an algorithm determines the outcome instead of a physical wheel. The RNG simulates randomness, ensuring that each spin is independent of the previous ones.

Is RNG random? True randomness doesn’t exist in software. RNGs are pseudo-random, meaning they follow a complex mathematical formula. In licensed casinos, third-party auditors test the RNG to confirm fair odds.

⚠️ How Casinos Could Rig RNG Roulette

  • Use fake RNG software that favors the house beyond standard odds.
  • Lower payout frequency when players hit winning streaks.
  • Manipulate results based on bet sizes or betting patterns.

🎥 Live Dealer Roulette – Real-Time Fairness or Hidden Tricks?

Live dealer Casinos hosting roulette involves a real croupier spinning a physical wheel in real time. It should be harder to manipulate—but not impossible.

🔍 How to Detect Rigged Roulette Games

Rigged roulette games often show patterns that don’t match true randomness. If certain numbers hit too many times or losing streaks seem excessive, something’s off.

Glitches and delays are another concern. If spins freeze before the result, or the ball slows down unnaturally, the casino may be manipulating outcomes.

Some rogue operators have even run fake Evolution Gaming tables. Always verify a casino’s license and test games before playing real money.

Can Casinos Track Your Bets and Adjust RTP?

Online casinos track every bet you place, including size, frequency, and win/loss history. Licensed casinos cannot legally adjust RTP based on your bets.

Unregulated sites use dynamic RTP to lower payout rates when players start winning or betting bigger. Rogue casinos manipulate odds over time, making big wins less frequent as sessions progress.

Casinos monitor player behavior for risk assessment, but can’t instantly change RTP per spin. However, some operators have used adaptive algorithms to tweak payouts.

In 2018, Playtech’s Age of the Gods roulette faced backlash when players noticed fewer high payouts in longer sessions.

Similarly, fake Pragmatic Play roulette games reduced big wins after a player’s balance increased. Talk about catching one’s hand in the cookie jar.

A common myth is that casinos use AI to ensure players never win too much. In reality, AI tracks betting patterns for marketing and fraud prevention, but it cannot alter game fairness in licensed casinos.

That said, there have been casinos where online casinos used hidden scripts to subtly lower win frequency over time.

Licensed casinos will never change RTP on the fly, but unregulated sites do. If a casino lacks independent audits or hides RTP details, avoid it. For complete transparency, provably fair games are the safest option.

Conclusion

Licensed sites use certified RNG software for digital roulette and real-time dealer monitoring for live games. Check for independent audits from eCOGRA, iTech Labs, or GLI.

Reliable casinos publish RTP transparency reports, proving that games follow true odds. Avoid unlicensed sites, as they often manipulate roulette results.
