Review Highlights

Through our casino reviews, you will be better placed on where you decide to play and win your favorite games. You can, of course, join more than one online casino operator, in fact, the average player will go through four different casinos in their first 6 months of playing.

This is common because players, understandably, will either feel they can get better service elsewhere, they get recommendations from friends and colleagues, plus there is the sway from advertisements. So, it is not unusual to be part of several sites as you venture into the world of online gambling.

The 5 key areas of a casino

Our reviews will help to highlight 5 key sections of each casino:

  • Games
  • Software
  • Support
  • Payment
  • Promotions

We will look at each section in closer detail in the topic below, but these are the prime areas to which service and features are covered. Other relevant details are provided to give you clarity over the minimal factors of the site, though play its part in the realm of online services and features.

These include:

  • Monthly Cashout Limits
  • Licensing Authority
  • Accepted Currencies
  • Exclusive Bonus Information

How we review the top 10 casinos

The process of researching on the Internet, to compiling a list of recommended casinos, is not an easy task. For us to present the best online casino reviews and to give you safe, secure, trusted and reputable options, the process of selections begins with the foundations of a casino. How it is licensed, are they legitimate and there any historical concerns about the company?


Because the Internet is a breeding ground for the few which try to ruin it for the many, we have to be wary of the fact that there are illegal sites, to which players, on the surface, wouldn’t recognize immediately.

So, of the sites which are on the Internet, we go through each one, which indeed takes months, we run checks on each to make sure that the owners of the sites have no previous expelled sites.

We then check to make sure they have the necessary license in place to service the counties they are targeting; this includes making sure those casino licenses are in-date. Aside from these main checks, we regularly check on the gambling laws and regulations to be sure sites are complying with the standards and the legalities with it come to performing as an online gambling service.

Once the ‘foundations’ are confirmed to be secure, we begin the process of trying and testing the services and features of the casino. These are later cross-compared to the approved casinos we have found and what will be found through new online casino sites that come into all global markets.

Here is a closer look at the individual areas which are, for us, the building blocks for a successful online casino website.


The games are the most important factor away from the security and legitimacy of a casino. This is the area where you will be spending most of your time and are the options that will provide you with real money wins.

For those unaware of what they want from a casino, we advise them to always focus on the games first. Rather than just picking randomly and hoping that you happen to stumble across games you will enjoy, it is far better to plan around the very things that bring the entertainment directly.

The casino is firstly checked that they are working in conjunction with an independent game tester. They will be the bodies that approve the games to be fair and honest.

Once we have established this, we log and not the variety of games they have. What we look for are casinos that offer quality over quantity. If a casino has over 5000 games and they are all of great quality, then their rating will be just as impressive as a casino offering 200 games of equal quality.

We look for what casinos that section their gaming areas off, it is far easier for a customer to have the standard virtual casino machines listed separately from those which are played with live dealers. You can learn more about this feature through this guide to live casino online.

The quality of gaming also links to the availability of bonuses which to play them with and with the software, which you are able to play them on.


When it comes to software, we discuss three important areas, the security of the casino site and the functionality of it and the software developers who power the site with their games.

The security of a casino is the #1 online casino rule when looking for legitimate online operators. Currently, the market is running off of software called Secure Sockets Layer or SSL for short. This is an encryption program the locks data passed between a web server and a browser. It helps keep the private information being transferred perfectly secured. We ensure that all SSL software is in-date and not at fault.

When it comes to functionality, all sites found on our list of recommended platforms will be compatible with various devices. You will find that any casino you choose will be accessible through any i0S, Windows and Android system. Because mobile gaming is now twice as big as desktop play, we make sure that you have access to your casino in the most convenient way.

If you like to have a casino that is specifically suited for a certain device then you have options here to read about here with a review on mobile casino options and Mac online casino. Also, with Android leading the online mobile gaming race, we have a special on them here, Android casino.

For the software developers, we can only advise you that you will be amongst those who have won the highest accolades from within the industry. We look for licensed and industry-approved gaming manufacturers. We make sure they are reputable gaming providers that come with a history of supply games that do payout.


Payment is, of course, vital. If you don’t have online casino payouts then what is the point playing, right? It’s one of the first things you should check when selecting your new online casino. Making sure that you are able to deposit payments in without any hassle and are able to withdraw your winnings through a fast and convenient method.

Do not assume that because of online banking services like Visa, for example, are so popular that every casino will be able to offer this option for both transactions in and out. You will find that there are some which do and other casinos that can only provide the service one way.

In assessing the casinos, we make sure that of the payment methods provided, that they are reputable services that are regulated by the Financial Service Authority (FSA). We want your casino to be able to provide a wide range of banking services as possible for the region you are in.

These payment services will include major credit card providers, there will also be third-party banking operators like PayPal, Skrill and Neteller. Then you have your alternative options which are prepayment services like Paysafecard and cryptocurrencies like Bitcoin.

If there is interest in learning more about the bitcoin option, then please refer to our review of Bitcoin casinos.

There are many different ways that you will see listed within the reviews to what each site has in terms of payment options.


For support, we focused on the customer care element of the casino. During a player’s time as a member, you may never have to ever contact them, but the reality is that there could be issues that randomly appear that need questioning.

We looked for services that we obtainable around the clock, hosted by professionally trained staff that know every feature of the casino they work in. We tested ourselves to see if they were able to assist with faux problems and what we learned is that there are incredibly dedicated people on-hand that are willing to help on issues relating to all sections of their site.

You will have bilingual customer support teams that can deal with your general account, through to banking, bonuses, and can even discuss gambling advice, technical matters and question on betting.


Here is where the eyes light-up and all else in the world fade into irrelevance. Promotions, bonuses, offers, rewards and gifts. The opportunity to play free online games from the casino is a reality. Because the casinos are regulated, you are guaranteed of honest and fair deals that will come through a mix of promotions.

Every casino has a welcome bonus to offer to its newest members. You will see these added to the top 10 list, or as above.

Again, the object of selection was quality and not quantity. There are deposit bonuses, no deposit bonuses, free spins, coupon codes, cashback offers, free sports betting, free cash credit and loyalty points, rewards and prizes to claim from all those you are able to read a review on.

Benefits of reading reviews online before joining

We believe that I order to succeed online, you and every other player must have a plan of action before they start to play with real money.

Pick the right casino straight

By knowing what you want to play, you can look for the best games. You then look for the best casinos online offering those games. You then begin to see if there are any rewards to play these games free and then check to see if they support your banking service to get those free winnings back.

This is a basic structure to selecting your casino, but it is a plan that puts you first, focusing on the games, through to being able to get your winnings from them for free and as securely as possible.

Why you should read before you play

In no way are the following comments a means of pointing the finger, we have all been a first-time player looking for a new casino online. The usual approach, to which we have fallen foul to, is to either go for the first online casino you see that pushes a huge welcome bonus onto new players, or you just go for one your friends recommended.

By having no insight, you are completely at the mercy of the casino and its services. You wouldn’t be aware of the fact that the grass is most likely greener on the other side, because you’d be too excited to play.

Having the facts laid out before you, you are then able to determine which casino has what before signing up to them. We formed the casino reviews by cross-comparing them on their qualities, you will have to do the same, so you get a casino which is perfectly right for you.

The additional benefit to planning your approach this way is that you get to enjoy exclusive bonuses that are not found through any other comparison site.

Here at Casino Bonuses, we provide new players with the opportunity to claim a sizeable bonus offer that comes with free spins and cash to help you win real money to keep!

100% honesty on the services of our recommended casinos

Our site covers the US market and as such, we have built up a proud reputation we would like to maintain. Our goal is to always help you win online casino real money in the safest way possible.

Our professional services treat you with trust

Every one of our casinos is a trusted platform we would gladly recommend. Because of our willingness to champion a casino for their hard efforts in being ahead of the pack, we are in a unique on that we can communicate with them to help supply new players with exclusive bonuses, but by no means does this affect our opinion of them long or short term.

Credibility and casinos

You will see that from our site, you are able to collect Bonuses of the Month, yet these are not the sites in the top spot or even top 10, they are recognized under merit for their efforts and in this case, for being able to produce bonus offers which go unmatched for their profitability.

The standards we set against casinos online are very stringent. We, like many players, want to be excited by the opportunities, we all want bigger jackpots, better games and more consistency in winning. If a casino doesn’t offer something that can either excite a player or cannot produce a service or platform that is to a high-quality, then it simply doesn’t make the list.

Why the right opportunity mattes

It would be of no benefit if we were to add casino options that were flawed with 1-star scores, informing you that the casino you are currently spending your time on, reading about them, is complete rubbish. It just serves no-one and wastes time.

If casinos are missing what we feel are key opportunities to excel as a platform, you will certainly read about them. Our reviews are strictly honest and, in any capacity, to provide productive criticism to help them, then we shall let them know and you know of where minor issues could turn a great casino into something more.

At Casino Bonuses we are happy to spread the word of casinos that are exceptional standard. You too can have your comments heard to help assist other players. You are able to provide a variety of feedback, which will be in the public-eye so please refrain from bad language and personal detail sharing.

Casino scoring

The scoring seen in the online casino reviews is entirely independent scores that come from online surveys that past and current players are able to leave their ratings on.

We do not influence the scores, in fact, you’ll read through our reviews about how well we felt the casino delivered on its overall service and yet you will see it was only scored by the players with a 3 out of 5 ratings.

You too will have your opportunity to rate the casino you join and help give a clear reflection of how they perform.

Making Improvements

Don’t be swayed in thinking that your opinion doesn’t matter. The standards of a casino are built on the voice of players and if there are things which you think need changing speak up.

Players hold all the power and it is the opinion that has helped shaped the best casinos online today. If you have any new ideas, then let your casino know, because they may very-well implement it for others that are after the same as you.
