There are many thousands of online casinos these days and the boom in online casinos is unbroken. Thousands of players from all over the world play regularly and new providers with a great range of games are established every day.

Unfortunately, this unbridled boom also attracts black sheeps and it is not always easy to find reputable online casinos. Unfortunately, the idea of making quick money with a quick and anonymous casino scam also tempts people with the wrong intentions to get involved in the industry.

It is therefore all the more important today to find out exactly which Internet casino you can play at and which operators are reputable. GamblersGuard helps you and offers all our readers the opportunity to leave their own casino reviews of online casinos. As long as your words are not offensive or defamatory, we will never censor. We believe nothing beats uncensored player ratings.

But even without the reviews of other players, there are some indicators that indicate that the provider is a site that should be avoided.

It is not always easy and it is not always easy to "blacklist" specific online casinos or gambling websites or to designate them as "dubious", since the situation in the gambling industry can change and the legal regulations vary from country to country are. But we want to show you some blacklist indicators that you should definitely check and that can indicate dubious management. It is important to note that online gambling is regulated in many countries and responsible gambling should be encouraged.

There are certain signs of potentially rogue online casinos that players should look out for. Here are some clues that could point to a dubious online casino:


Missing or invalid license

Reputable online casinos usually hold valid gambling licenses from recognized regulatory bodies. If an operator does not provide license information or indicates an invalid license: Get out there!

Lack of transparency

A reputable online casino should be transparent about their terms and conditions, withdrawal policies, bonus terms and other important information. If this information is difficult to find or unclear, the casino could be untrustworthy.

Negative reviews and complaints

Research other players' experiences with us, read player reviews and look for complaints about the online casino in question. If there are a lot of negative reviews or frequent complaints, that could be a clear indication of a dubious casino.

Unfair Business Practices

If an operator employs unfair business practices, such as delayed payouts, rigged games or opaque bonus terms, this is a clear sign of a lack of seriousness.

No secure payment options

Reputable gaming sites usually offer secure payment options to ensure player privacy and security. If the online casino does not offer secure payment options or uses questionable payment methods, it could be classified as untrustworthy.

It is important to emphasize that these signs alone do not necessarily mean that a gaming site is rogue. It is advisable to do thorough research and check different sources to make an informed decision before registering or depositing any money at an online casino.
