How we Rank

To feature on 5Star, we review each casino as thoroughly as possible, making sure we only include the very best Online Casinos. They need to earn their stars by showing they’re one of the very best places for UK players to play.

In order to achieve a 5 Star rating we judge them on several topics, where we have a thorough checklist with questions like:

☆ Bonuses/Promotions

Are their bonuses competitive, engaging and easy to claim? Do they offer a Welcome Bonus/Welcome Package for new players? Do they keep existing members happy with regular promotions? Is it easy to understand their bonuses with clear terms and conditions? Do they reward their loyal players? Plus a through examination of all the promotions on offer.

☆ Software/Games

Do they have sleek and fast graphics? Is the gameplay good? Does it have fast loading times? Is it easy to navigate the site? Is it mobile/tablet compatible? Do they have a varied selection of games? Do they have multiple variations of the same games – e.g. European, American, 3D roulette etc? Do they have table games, slot and live games? and many more

☆ Cashier

Is there a good selection of banking methods? Is the site secure? Is it easy to deposit funds? Are withdrawals processed quickly? Start to finish, is it an easy and quick process?

☆ Customer Support

Do they have an easy to use Help section? Do they have easy to find contact information? Is the information clear, including hours of operation, country codes etc? Do they offer a variety of customer support methods – e.g. Email, Phone, Chat, Mail? Are they quick to respond? Do they offer good service? Are they polite? Are they knowledgeable?

☆ Overall

Before we give an online casino a 5 Star rating we’ll answer all the above questions and more, and we’ll need to get a big YES to all of them to issue our 5Star approval. Of course all casinos will also need to be mobile and tablet compatible and be UK regulated to meet specific standards for fairness, safety and security.
