casino reviewsA lot of what we do here at Online Casino King, is to review casinos that are available online in the UK and around the world. Some of our favourite casinos are sites such as Spin Palace Casino, 32 Red and Sky Vegas Casino. They all have their plus points and their minus points (nobody’s perfect, right?), so in the end it comes down to personal preference.

We have ordered our independent reviews on the site based on the software platform so that you can find your best onine casino. There are many brands of online casino, but much fewer companies that actually develop the games and write the software that powers the casinos. If we compare the online casino industry with the car industry, for example, it´s a bit like the difference between VW, Seat and Skoda. 3 different companies, with different products and prices who are based in different countries, but lift the bonnet of a Skoda Octavia and a VW Passat, and you will see the same engine with a different badge on it.

Of course, it´s easier to develop an online casino than a car- the expensive part is the software, “underneath the bonnet”. That is why you have such a profligeration of casino brands online. When you are comparing online casinos, it often makes sense to compare within the same software group. That way, you know the fundamentals are the same and you can concentrate on comparing other factors like bonus offers, customer service and payment methods- for example.

We have tried to keep our casino reviews clear and simple to read, with all the main criteria that you’ll need to make an informed choice about where to play online. You can compare the different casino bonus offers here, and more importantly we list the basic terms such as the playthrough requirement (the amount of times that you need to bet your free bonus before you can withdraw any winnings).
