How do we choose our Top 10 Slot Sites?

As a comparison website, you may be wondering why you should take our word for it that these are the best slot sites. After all, it’s not a huge secret that many comparison sites are paid by slot and casino companies to highlight their sites high up on the rankings. However, we don’t work that way. We launched Compare Casino Sites because we actually care about your experience. We love the thrill of playing on a slot site and want others to be able to enjoy that same exciting feeling.

We have pretty high expectations when it comes to the online slot experience. Therefore we aim to make our reviews as comprehensive as possible. We won’t hold back on mentioning any negative aspects of each site. The only real way you can get a true idea of a slot site is if you know as much as possible about the pros and the cons. Most sites tend to have at least one potential downside. If there is one, we’ll tell you about it.

What do we look for?

When creating online slot site reviews there are quite a lot of things we look into. We obviously want to make them as helpful as possible so we split them down into easy to read sections. The main factors we look at include registration, games, design, promotions, loyalty and VIP schemes, and the company information. In order to make it onto our top 10 slots list, each site needs to deliver in every aspect of the above points.

We look at how easy it is to register and whether there is a good choice of games. It isn’t all about the selection of games available however; we also look at the quality of gameplay and which software the site uses. Quality is often more important than quantity. A site can have hundreds of games, but they might not be offering high quality gameplay.

The design of the site is also important. Not only do we look at how attractive the actual design is, but we also take into account how easy it is to navigate around. It is all well and good having a flashy website, but if the games and information on the site aren’t easy to find, it negatively effects your overall experience.

Promotions are definitely an important part of online slot sites. A lot of people end up joining a site based on promotions alone. We’ll tell you more about the welcome offers available, as well as regular promotions you can expect. The best slot sites have partially been chosen because of their excellent range of promotions.

As well as promotions, players also often prefer to play on a site that offers a generous loyalty scheme. Not all slot sites will feature a VIP scheme so if this is important to you, be sure to pay attention to our loyalty scheme section of each review. Loyalty schemes give you the opportunity to earn points every time you make a deposit or play on certain games. Those points can then be redeemed for either cash or various prizes.

Finally company information is also important. It is always good to know who you are dealing with and whether the company is properly licensed. All of the sites on our top 10 list have a genuine, up-to-date gambling license and focus on good customer service. We also look at how long they have been operating and how popular they currently are.

There are so many things that you need to know before you sign up to a site. By reading our reviews you can be sure you’ll learn everything you need to know. We don’t just check out new sites either; we continually check in with old and trusted sites to see how they are faring up against the competition.
