Our Rating Methods

We put a lot of time and effort into ensuring we can guarantee you a thorough assessment of all UK slot sites. We only showcase the sites which pass our safety checks.

Our review writers go through and assess the strengths and weaknesses of all the sites that ask to be listed on our site. They sign up as a player to each site and go through the following steps:

  1. Monitor the simplicity of the signup process including the ease and speed of compliance checks.
  2. Testing the bonus offers offered by the casinos and comparing them with other slot sites to compare and contrast the value of each slot sites bonus.
  3. Deposit and withdraw using different deposit methods to monitor the speed in which deposits and withdrawals are concluded. We also make note of the number of banking methods available on each slot site so we can compare them with the rest.
  4. We will also test a large selection of slot games on the site to inspect the experience, speed and game choice. Slot sites tend to vary heavily on this point; whilst some are slow and sluggish others can be very user friendly.
  5. The variety of slot games. Does the casino have a mixture of slots from many different slot providers?
  6. We check how mobile friendly the slot site is. Although most slot sites in the UK are built for mobile first, there are still a few of them which do not pass our mobile friendly test.
  7. VIP programmes and loyalty schemes. We check how generous the site is to their current players. Often slot sites will overlook their current players in favour of attempting to lure in new players.
  8. Talk with the customer support team and find out what support is available. The best slot sites in this category will offer a 24/7 live chat support team.
  9. We check the security at the casino. We will only feature slot sites who are able to promise their players that their money will be 100% safe.
  10. Does the slot site offer responsible and safe gambling? We rate sites much higher if they can guarantee safety checks to their players.
