The online gambling sector is attracting more and more users because of its convenience and the opportunity to earn money quickly. The growing popularity of virtual establishments is leading to an increase in the number of untrustworthy sites. To avoid risk and money loss, it is important to know which online casinos are blacklisted and why they should be avoided. Let’s take a look at the signs of fraudulent platforms, ways to check licences and examples of institutions that have proven to be unfair to players.
Blacklist of online casinos: what is it and why is it important to know?
The blacklist is a list of gambling companies that systematically violate customers’ rights. The reasons for inclusion in such a list are usually problems with payouts, falsification of game results, ignoring user complaints or problems with account verification. Independent sites and forums such as AskGamblers or CasinoMeister: they regularly update the lists of unscrupulous platforms based on numerous complaints and verified online gambling frauds.

Which online casinos are blacklisted – signs:
- Unwarranted delays and refusal to pay out winnings.
- Manipulation of game results, violations of random number generator (RNG) conditions.
- Fraudulent bonus systems, including hidden conditions that make withdrawal almost impossible.
- Constant verification problems and delays.
- Operating without a licence or falsifying documents proving the existence of a licence.
Which online casinos are regularly blacklisted?
Looking at the examples, it is worth examining in detail the individual devices and the reasons why they are found.
Zeon: misleading gloss and frequent complaints
Despite its attractive design and enticing bonus offers, Zeon regularly delays payments for more than 45 days, claiming it has ‘technical glitches’. One case is often cited on forums where a user who won around $3,000 in 2024 was never able to withdraw the money due to ongoing verification problems.
St. Tropez: unfulfilled promises and opaque terms and conditions
This casino has long been known among players for frequent complaints about failure to pay out large sums of money. In 2023, there was a case where a customer was unable to withdraw $7,000 won on slots because the platform blocked his account without explanation. The signs of a rogue casino are obvious here: opaque withdrawal terms, lack of support and constant downgrades.
Inbet: illusion of reliability and licensing problems
Which online casinos are blacklisted can also be examined using the example of Inbet. In 2024 revealed that the portal provides players with false information about the presence of certification. Checking the online casino’s licence on the official sources of regulators revealed that the documents were not valid. This confirms Inbet’s deliberate actions to mislead users.
Flint: a long way to lose and perpetual withdrawal problems
Flint has been on the lists of problem institutions for years. Players complain about the inability to withdraw even small winnings. A visitor who won $1200 in 2025 is still waiting for the money, while the support team ignores his calls and shifts responsibility to the payment systems.
Dandy: an attractive package with unpleasant surprises
The casino usually lures players with shiny promotions, but bonus fraud is a regular occurrence here. For example, the wagering conditions are so complicated that it is almost impossible to withdraw the money won. In 2024, more than 500 complaints were received from Dendy users about wrongful cancellation of bonus money.
Put: beautiful games and endless complaints about RNGs
This online casino is best known for being blacklisted for manipulating session results. In 2023, an independent audit of the RNG revealed serious deviations from eCOGRA standards, showing that odds of winning were artificially low by 20-30%.
How to check the reliability of online casinos: simple recommendations to protect your money
To minimise risks and avoid fraud losses in online gambling, it is necessary to have a good understanding of how to check the reliability of the platform. Despite their apparent appeal, not all gambling companies comply with strict rules and fair gaming conditions.
Checking the licence: where to start?
The first and most important measure to check the safety and fairness of an establishment is certification. Large and reputable regulators such as Curaçao eGaming, Malta Gaming Authority (MGA) or UK Gambling Commission (UKGC) publish lists of licensed sites on their official websites. To check authenticity, find the certificate number on the casino’s official website and enter it on the authority’s website.

For example, if the operator claims to have an MGA/B2C/123/2020 licence, just go to the MGA source, enter the number and check the validity. If no licence is found or the status has expired, the establishment is immediately blacklisted.
Study player ratings and independent site reviews
The second important step of checking is a thorough analysis of reviews on specialised sources such as AskGamblers, CasinoMeister or Trustpilot. Reputation is formed precisely on the basis of real reviews from users who have already experienced interaction with the institution. It is worth paying attention not only to the number of positive or negative reviews, but also to specific details:
- How often are problems with payments and their delays mentioned?
- What difficulties were encountered during verification?
- How does the casino respond to criticism and complaints?
- Have there been cases of bonus fraud?
Evaluate the effectiveness of the player support service
Testing the support service is another effective way to check its reliability. To do this, you can independently contact the operator with questions and evaluate the following parameters:
- Response time (ideal time: no more than 2-3 minutes in online chat and no more than an hour by e-mail).
- Quality and completeness of comments, clear wording and willingness to help solve the problem.
- Ability to communicate in several languages, including Russian or English, confirming the high level of service.
Quality platforms, such as 888Casino or PokerStars, offer 24-hour support and resolve any problems quickly, while unreliable sites respond formally or ignore requests altogether.
Which online casinos are blacklisted: how to avoid risk and play safely?
It is important for users to remember that self-verification and a critical approach help to significantly reduce the risk of losing money on gambling platforms. Avoiding verification problems at online casinos is also possible by choosing settings with simple and clear rules for document verification and minimum withdrawal times.
Conclusion
If you know which online casinos are blacklisted, you can significantly reduce the risks and choose a reliable place to play. By following a few simple recommendations, you can successfully avoid virtual gambling fraud and enjoy your sessions without unnecessary worries. A conscious approach and attention to detail make the gambling process as safe and comfortable as possible.
