All online casinos honestly reviewed - if something's bad, we'll call it out! Unbiased casino reviews of the good and bad, stay safe while gambling online.

When going to online casinos in order to find out which one you should play at next, there are multiple points you should consider. These include the online casino gambling license details, available payment methods, customer support information and game selection to mention a few.

Gathering all this info can take long and require some investigation skills, which is why many players rather read casino reviews. Our team of casino players turned professionals do the dirty work for you and figure out for example whether the site is an independent casino or not.

In case you already know what you want from a casino, you can use that to narrow down the above casino comparison list. Just apply the filters and you will only see the online casino sites that fit your specifications. Then you can get to know the casino deeper by reading the review.

Casino reviews reveal all you should know about the online casino

Before we review casino online, we personally perform some tests to assess the overall quality. We want to make sure it meets our high standards. For the online casino review we check all possible factors, but most notably the following:

  1. Website usability
  2. Customer service quality and availability
  3. Mobile compatibility
  4. Selection and standard of games and providers
  5. Payment methods (deposits and withdrawals)
  6. Casino bonuses

Our rating scale goes from 1 Mr Gamble coin to 5 being the best. Each section is separately rated and the casino’s overall score comes from the average of the rating results. This way you can be sure that the casino review truly takes everything into account.

Casino 2021 Reviews

    New online casinos are launched regularly, and not all of them are worth trying. Casino review sites like Mr. Gamble won’t even list the worst ones so that you wouldn’t have to suffer through what we did, but post the online casino review, so that you can find it if you want.

    On the above list you’ll find the recently launched casinos we have rated high enough to recommend. You can get to the new online casino reviews by clicking the casino’s name. Next to it is the casino welcome offer available for players who sign up for the first time. The ‘Play’ button will then take you to the casino site.

    Best casino reviews focus on top player experience

    It sounds like a no-brainer, but not all casino reviews are conducted by actually testing out the casino. Just because something is new or looks nice doesn’t mean it’s practical, and this is unfortunately the case for some online casinos. The best online casino sites reviews go deeper than the surface.

    It’s also no use for a casino to have a large game collection in case they load really slowly or a big casino bonus if the wagering requirements are impossible to fulfil. Honest casino reviews are based on real experiences and make sure to convey all information players might find useful.

    Online Casino Real Money Reviews – Testing deposits and withdrawals

    Read the best online casino reviews that are based on unbiased real money testing of the casino site and feedback from players who help review casinos online.

    s have always been instant. Traditionally, all real money deposits to online casinos have been made with bank and credit cards such as VISA and Mastercard. Today, there are hundreds of other options. Withdrawals, though, have always been a bit more tricky.

    Withdrawing your winnings using the mentioned payment cards have always been liable to a waiting period of 3-5 banking days, and still are today. But, today, we have an abundance of other options for withdrawing money from a casino account. Many of them are instant.

    All our online casino reviews include specifics about the payment and withdrawal methods available. We also point out if the casino terms and conditions mention transaction fees or exclusion from bonuses when using specific banking methods. Then there’s the topic of paying taxes on winnings.

    Casino licence ensures safe gambling

    One of the main things that affects playing experience greatly is the gambling licence the casino holds. The licence requirements dictate the minimum efforts the casinos need to make about player safety and responsible gambling. It also determines whether the winnings are tax free, like at the above casinos.

    Apart from online casino reviews the licence information can be usually found at the bottom of the casino’s front page. In case you either can’t find the information anywhere or the casino simply does not have a licence we strongly recommend against playing there.

    Why read casino site reviews?

    New and experienced players both benefit from online casino reviews. They are a good way to learn what you should pay attention to when getting to know a new online casino and let you know whether the casino site has what you are looking for.

    Independent online casino reviews convey a realistic picture of the casino and what's left for you to do is to choose the one that pleases you the most. There is surely a casino or multiple out there for everyone, and on this site you can find everything from bitcoin casino reviews to mobile casino reviews.

    Bonus terms and conditions

    Most players look for a casino bonus as an incentive to join the casino, and top online casino reviews go also through bonus terms and conditions. That way you can make sure there are no unpleasant surprises in either the claiming, playing or withdrawal stage. 

    For example many casinos offer free spins or bonus money with your first deposits (or even no deposit bonus), but online casino bonus reviews will point out that these usually have limitations regarding winnings or games they’re eligible for and wagering requirements. 

    Games and providers

    Casinos are extremely versatile online gambling places, and the biggest ones can offer thousands of different games. Live dealer casino reviews focus on casinos that have real time hosted games played against others often sought after by players who want authentic casino experiences.

    Others have favourite game providers they base their decisions to join the casino on. That’s why it’s not uncommon to find, for example NetEnt casino reviews, as it’s one of the biggest and most popular providers online, both for slots and live casino games.
