The rapid growth of online gambling has opened the doors to convenience, variety, and 24/7 access—but it has also led to an alarming rise in scam casinos. With little oversight in certain regions, many rogue operators have taken advantage of unsuspecting players. In fact, a 2021 report estimated that the global black market for gambling rakes in around $1.7 trillion annually. Even more worrying, four out of ten gambling-related Google search results are linked to unlicensed or potentially fraudulent websites.
These fraudulent platforms lure players in with flashy promises—huge bonuses, exclusive jackpots, or easy registration—and then disappear with their money or data. For those who are new to online gambling or unfamiliar with how legitimate platforms work, the risk of being scammed is even higher.
This is why being able to spot the red flags of a scam online casino is essential. At 91 Club, we prioritize transparency and player protection. In this guide, we’ll show you the top five warning signs that indicate a casino might not be trustworthy—so you can play smart, stay safe, and enjoy your gaming experience with peace of mind.
Lack of a Valid Gambling License
One of the most obvious and crucial signs of a scam online casino is the absence of a valid gambling license. A legitimate license ensures that the casino follows regulations that protect players, enforce fair play, and offer dispute resolution mechanisms. Without one, you’re essentially handing your money over to a site with no legal obligations or accountability.
Licensed online casinos must meet strict criteria related to:
-
Random Number Generator (RNG) fairness,
-
Player fund segregation,
-
Responsible gambling policies,
-
Data security and encryption.
The most reputable licensing authorities include:
-
The Malta Gaming Authority (MGA),
-
The UK Gambling Commission,
-
Curaçao eGaming,
-
Gibraltar Regulatory Authority.
These regulatory bodies conduct background checks, regular audits, and monitor compliance. You can usually find a casino’s license number and regulatory body listed in the footer of their homepage. If this information is missing, vague, or unverifiable, that’s a big red flag.
Always take a few minutes to verify the license through the regulator’s official site. A legitimate casino has nothing to hide.
At 91 Club, we are committed to legal compliance and transparent operations. We display our license details clearly, so you always know you’re in safe hands. Choose licensed platforms like 91 Club to enjoy secure and fair play every time.
Know Your Customer (KYC) is a process that verifies the identity of players to prevent fraud, money laundering, and underage gambling. Legitimate online casinos are required to implement KYC procedures in compliance with international regulations and best practices.
During KYC, a player may be asked to submit:
-
A government-issued ID,
-
Proof of address (such as a utility bill),
-
Proof of payment method (like a screenshot of a bank account or e-wallet).
Although some players may find this step inconvenient, it is a sign that the platform takes security seriously. Scam casinos often skip KYC entirely to make it easier to take your money without verification. This not only puts your personal information at risk but also allows these rogue platforms to operate anonymously.
A lack of KYC is particularly dangerous when it comes to withdrawals. Many scam sites will accept your deposit without question but block withdrawals until you provide documents—only to never respond or claim your information is “incomplete.”
At 91 Club, our KYC process is transparent, secure, and designed to protect your identity and assets. We follow strict anti-fraud policies and comply with industry standards to create a trustworthy gaming environment where your safety always comes first.
Overwhelmingly Negative Player Reviews
Player reviews and testimonials are valuable resources when researching an online casino. While every casino may receive a few complaints, scam casinos tend to have a pattern of repeated issues that go unresolved.
Some warning signs to look for in reviews include:
-
Delayed or denied withdrawals,
-
Unresponsive customer service,
-
Rigged or unfair games,
-
Suspicious account closures,
-
Misleading bonus terms.
Check multiple platforms, including Reddit forums, Trustpilot, and review websites specific to online gambling. If the same complaints appear again and again, that’s a strong signal the site should not be trusted.
Also, be wary of fake positive reviews. Some rogue operators pay for glowing testimonials to lure in new players. These reviews often look generic or overly enthusiastic. Trust user-generated content with detailed feedback over anonymous praise.
At 91 Club, we’ve earned a reputation for fairness and reliability. Our community of loyal players continues to grow because we listen, respond, and deliver. Transparency is our policy, and your satisfaction is our priority. Don’t take unnecessary risks—play where thousands of players feel safe and respected.
Vague or Manipulative Terms & Conditions
The terms and conditions (T&Cs) of an online casino dictate everything from how bonuses are issued to how withdrawals work. Reputable casinos offer clear, straightforward T&Cs that are easy to read and understand.
Scam casinos, on the other hand, often hide unfair practices in vague or confusing language. Some red flags to look for:
-
Hidden withdrawal limits,
-
Unexpected account fees,
-
Unclear bonus wagering requirements,
-
Sudden policy changes without notice.
One common tactic involves altering the rules after you’ve already started playing. For example, a scam casino might change its withdrawal policy right before you try to cash out, claiming you’re ineligible due to “new” rules buried in the fine print.
Always read the T&Cs carefully. If anything feels deliberately misleading or hard to understand, walk away. Remember, trustworthy casinos have nothing to hide.
At 91 Club, our terms are transparent, regularly updated, and easily accessible. We believe in clarity and fairness, so you can focus on enjoying your game—not decoding legal jargon. That’s the kind of service you deserve.
Unrealistic or Deceptive Bonus Offers
Online casinos use bonuses to attract players—but scam sites exploit this strategy with offers that are too good to be true. These “bonuses” often come with impossible wagering requirements, tight deadlines, or unclear restrictions.
Imagine seeing a 100% match bonus up to $5,000. Sounds amazing, right? But the fine print says you must wager 60 times the bonus amount within 5 days to make a withdrawal. That’s nearly impossible unless you’re risking huge sums.
Other deceptive tactics include:
-
No-limit bonuses that are revoked without explanation,
-
“Sticky” bonuses that can’t be withdrawn,
-
Hidden restrictions on games eligible for wagering,
-
Sudden disqualification from bonuses based on obscure rules.
Good casinos like 91 Club provide bonuses with clear conditions. We state our wagering requirements up front, and we never use misleading promotions to bait players. Our goal is to enhance your experience, not to trap you.
So before you claim any bonus, always read the terms and calculate whether it’s realistically achievable. If it sounds too good to be true—it probably is.
