Blacklisted Online Casinos in 2025

Playing at blacklisted online casinos poses certain risks for players, including financial and emotional harm. To help you avoid such problems, we have put together a list of blacklisted sites you should steer clear of, how to identify trustworthy casinos, and what to do if playing there. Keep reading to find out.

5 Common Reasons Casinos Are Blacklisted

Blacklisted casinos operate without a valid gambling license, so they change rules arbitrarily or shut down without warning. Also, they manipulate game outcomes, lack security measures, and impose complicated withdrawal processes.

No Valid License

A valid gambling license is an important indicator of a trustworthy casino. Licensed casinos must follow strict regulations to ensure fair play and protect customer funds.

However, an untrustworthy casino often operates without a valid license or claims to have one that is fake or expired. Without proper oversight, they change their rules at any time or even shut down overnight without warning. Hence,  when a player encounters issues, there is no regulatory authority to step in and help resolve the problem.

Rigged Games

Online casinos use certified Random Number Generators (RNGs) to guarantee that game outcomes are fair and random.

On the contrary, unreliable platforms manipulate their games to make it nearly impossible for players to win. They use unfair algorithms that drastically reduce payout chances, meaning the games seem legitimate yet cause players to lose more than they should.

In the worst-case scenario, the casino even fakes wins to lure players into thinking they are close to hitting the jackpot, only to continue draining their funds.

Unpleasant Experience

Casinos must provide a smooth and enjoyable gambling experience, but a blacklisted platform usually fails in this area. Its customer support teams are unresponsive or misleading, either ignoring complaints or providing false information about promotions and withdrawals.

Casinos in the warning list also use deceptive marketing tactics (e.g., advertising big bonuses with hidden terms that make it nearly impossible to cash out). For example, a casino offers a 500% welcome bonus but requires players to wager the bonus amount 100 times before withdrawing, which is almost unattainable.

Lack of Security

Security is crucial when gambling online since players share sensitive financial and personal information. That explains why reputable casinos like DraftKings or Bet365 use strong encryption and strict privacy policies to protect their users.

Meanwhile, blacklisted casinos usually have little to no security measures in place, putting players at risk of fraud and identity theft. They also sell user data to third parties that expose players to scams and spam, meaning cybercriminals find it easy to steal money from player accounts.

Complicated Withdrawal Processes

Lastly, unethical casinos often delay payouts indefinitely, ask for excessive documentation, or impose hidden fees that eat into winnings. Another warning is that they also use unfair conditions (e.g., requiring players to deposit more money before withdrawing) or claim that a player’s winnings are void due to minor technicalities like account verification delays.

In extreme cases, a casino refuses to pay out winnings altogether (making excuses or simply ignoring withdrawal requests). Platforms that make it difficult or impossible to access winnings are a major red flag and a common reason for denylisting, as shown in the full list of unqualified casinos below.

How to Find Reliable Online Casinos

To find a reliable online casino, always check for a valid license, strong security measures, clear terms, responsive customer support, and positive user reviews before signing up:

• License: As mentioned, a valid gambling license (e.g., from the UK Gambling Commission) proves that a casino is legally authorized to operate and follows strict industry regulations.
• Security: It’s best to avoid a casino altogether if it lacks encryption, offers only obscure payment methods (e.g., prepaid cards from unknown providers), or has no privacy policy.
• Clear terms and conditions: Reputable casinos have transparent and fair terms and conditions. For example, they clearly state withdrawal processing times and any daily, weekly, or monthly withdrawal limits. By contrast, unreliable casinos use vague language and hidden clauses to trap players.
• Customer support: Test the casino’s support before depositing money. Good casinos offer 24/7 support, while shadier ones operate only during limited hours or never reply. Also, look for casinos with multiple options, such as live chat, email, phone support, etc.
• User reviews: Checking real user reviews is one of the most popular ways to assess a casino’s reputation. Beware of casinos with too many complaints about non-payment, rigged games, poor customer support, etc.

When finding a shady casino that fails to check all these boxes, you should do something about it instead of just letting it slide. Keep reading for our suggestions and gambling guide on what to do.

What to Do When You Find A Shady Online Casino

To deal with a shady online casino, contact the casino’s support team (live chat, email, etc.). When the casino refuses to cooperate, escalate the complaint to the authority, report it to PeakyCasino, or seek legal counsel.

Contact The Casino

Before escalating the situation, the first step is to contact the casino’s customer support team and attempt to resolve the issue directly. Certain problems (such as delayed withdrawals, verification requests, or bonus misunderstandings) are easy to address with a simple conversation.

In addition, most reputable casinos have a live chat feature, which is usually the quickest way to contact support staff. Sending a detailed email to the casino’s official support address is another option if live chat is unavailable or the responses are unhelpful.

When communicating with the casino, it is important to remain clear, firm, and professional. Clearly describe the problem and provide any necessary details, such as transaction IDs, timestamps, and screenshots, and request a specific resolution. When the casino’s support team ignores your messages or refuses to cooperate, move on to the next step.

Contact The Regulatory Authorities

For casinos that are licensed by a recognized regulatory body, you should file a complaint against them to initiate an investigation.

Licensing authorities oversee casino operations and ensure they follow fair gaming practices and treat players ethically. They have online complaint forms where you submit details of your issue, along with supporting evidence such as screenshots, chat logs, transaction records, etc.

However, this step does not yield results if the casino is unlicensed or operates under a weak regulator that does not enforce fair practices. In that case, you must take additional action.

Contact PeakyCasino

Once you confirm that a casino is engaging in fraudulent or unethical behavior, reporting it to PeakyCasino is an effective way to warn other players and help prevent further victims.

We regularly update a denylist of unreliable online casinos so players easily check for scam sites before depositing money. Hence, reporting a dishonest casino to us means you contribute to a growing database of player experiences that influence others’ decisions and put pressure on fraudulent platforms.

To report a shady casino to PeakyCasino, visit our contact page and submit a complaint. Provide the casino’s name, website, and a detailed description of the issue you experienced. Supporting evidence (such as screenshots of conversations, withdrawal requests, payment confirmations, and emails from customer support) strengthens your report.

Seek Legal Counsel

Players who have suffered a large financial loss due to fraud, unfair treatment, unethical practices, etc., should consider seeking legal assistance. While doing so is usually time-consuming and costly, it’s still worthwhile if you have strong evidence to support your claim.

The first step in pursuing legal action is to gather all relevant documentation, including chat logs, emails, screenshots, payment records, and proof of any attempt you made to resolve the issue with the casino.

Once you have a strong case, consult a lawyer who specializes in online gambling disputes or consumer protection laws. They will assess your options and determine whether you have a valid claim, then advise you on the best course of action.

In certain circumstances, you are able to request a chargeback from your payment provider. Players who have made a deposit using a credit card, PayPal, or another regulated payment method also have the option to contact the provider and dispute the transaction on the grounds of fraud.

Can A denylisted Casino Be Removed from Our List?

Yes, a casino can be removed from our casino denylist, but only if it successfully resolves all outstanding issues and proves that it has changed its practices.

For a casino to be reconsidered, it must address all player complaints, honor previously withheld payouts, improve its customer support, and demonstrate full compliance with fair gaming standards. Additionally, we conduct a thorough re-evaluation, which includes testing the platform, verifying user feedback, and ensuring that the casino now operates transparently.

That being said, removal from our blocklist does not happen often, as most casinos that engage in unethical behavior continue to do so. Players should remain cautious when dealing with previously denylisted casinos.

Can Players Be denylist As Well?

Yes, players can also be blacklisted from gambling. One of the most well-known denylist is the EPIS (Excluded Persons Information System), which completely bans individuals from accessing physical casinos, betting shops, and online gambling platforms.

Players end up with casino warnings for various reasons, such as:

• Requesting self-exclusion for responsible gambling or due to gambling addiction
• Violating casinos’ terms and conditions
• Engaging in fraudulent activities
• Being flagged for problem gambling behavior

Once faillisted, players cannot register, deposit, or place bets at any licensed gambling site or establishment that follows EPIS regulations.
