With an unbeaten selection of top-class casinos to choose from, Think Casino is the go-to reference guide for British online casinos! We list all the latest casinos that launch in the UK as well as maintaining a list of the Best UK Online Casino Bonuses, from no deposit bonuses to incredible instant UK free spins no deposit bonus offers that you can claim immediately after registering your new player account.
The Think Casino website is the original UK bonus site that has been sharing tips and advice on selecting the best online casinos for over ten years. We make it our mission to explain and de-mystify the confusing world of online gambling offerings open to the United Kingdom public.
The slots and games are obviously a huge consideration too and various casinos specialise in different types of games and online gaming software providers. It's important for a prospective new player to get the lay of the land at an online casino and get the low down on the online casinos reputation before embarking on real money online gambling.
Our online casino experts have cast their seasoned scrutiny upon the majority of UK Gambling Commission licensed brands available to UK players. We have applied a number of criteria to judge the casinos and help UK gambling fans find the right place for them.
Why should you trust our reviews?
We believe that Think Casino is the best source of new UK casino sites and online casino reviews. We do not ask payment for placement, we do not list non-UK licensed casinos. All our casino brands have been hand selected because they offer players the best experience, the fairest deal and an excellent choice of slots games.
Remember: Always read the casinos terms and conditions before you go ahead and claim a bonus or offer.
