How We Review & Compare UK Slot Sites & Casinos

When we review any online gambling sites we follow a few very important rules. Using our industry knowledge we will analyze the games themselves, customer support, payment methods and more. If any online casinos do not meet all our criteria then we simply refuse to list them. The casinos that are listed on Spin Bonus have been thoroughly reviewed and meet our exacting standards, as explained below:

  • Background & Reputation – First of all, we take a look at the company behind the casino, probe its reputation and look over any sister sites owned by the same company.
  • Registration – We register at the online casino and asses the ease of the registration process
  • Usability – We will browse the casino lobby and click around the site to assess the quality of navigation and ease of use.
  • Game Selection – Our reviewer will try out and play the slots and table games, gauge the game options and the selection and choice of software providers.
  • Software Providers – We test and make sure that all the online casinos we list have games by top software developers such as Microgaming, Playtech, Netent & many more.
  • Banking – We diligently check the casino deposit and withdrawal options and weigh up the number of options such as Paypal, Neteller & Paysafecard
  • Bonuses – Our expert will evaluate the ease and process of claiming the welcome bonus and check terms and conditions and wagering requirements. If a deposit is required to claim the bonus we will make the minimum deposit
  • Promotions – We note the quality & quantity of the current promotions and research the regularity of new promotions being added.
  • Payout Speed – We investigate the casino withdrawal options and cashout times, fast payout casinos get bonus points from our reviewers.
  • Customer Service – The Reviewer will check the amount of customer support options and response times to determine the quality of customer service.
  • Mobile Compatibility – We then repeat steps 3 & 4 on iOS, Android & Windows mobile devices to ascertain the casino usability on mobile phones and tablets.

Brand New Casinos

new sites

Choosing a new casino or slot site to play at can be tricky. There are so many brands in the industry offering numerous welcome bonuses, promotions and premium online slots and casino games, plus there are new UK casino sites almost daily.

Not every punter has the time – nor the hefty bank balance – to trial every new casino in order to find the best new gambling sites to suit their needs and preferences. Additionally, it can be problematic for UK players to figure out the best new casino sites which offer fair, safe and officially UKGC regulated gameplay.

That’s where our expertise comes in handy. We’ve done the hard work; we’ve spent hours upon hours rigorously testing and reviewing many new casinos, and we only recommend premium platforms that are licensed and regulated by the UK Gambling Commission. The new online casino and slot sites we endorse feature impressive games libraries, competitive casino bonuses, lucrative loyalty schemes and regular promotions.

There are many factors that go into choosing the best online slots sites that are the right fit for you, so we have used our experience and knowledge of the industry to put together to make it easy for you.

We have taken the time to go through some of our favourites online slots sites and highlight their main features so that you can choose which site is best for you, based on the features that are most important.
