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:
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.
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
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?
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.

One of the ways Online Casinos will try and temp you in will be with the use of bonuses. These bonuses can be an excellent way to increase your stake and give you a better starting balance at the casino. Some casinos will even give you bonus money just for registering, before you even make a deposit, while others might give you free spins or bonus spins.
Bonuses will typically fall under 6 main categories:
Matched Welcome Bonus on Deposit
The most common welcome bonus is the matched deposit bonus. This is where the casino will double, triple or sometimes even quadruple your first deposit. This is normally displayed by telling you the maximum percent your deposit can be matched, and how much you can get as a bonus e.g. 400% up to £500. So if you deposit £125 the casino will quadruple it up to £500 so you’ll actually have a whopping £625 to play with. This bonus might also sometimes include free spins before or after your first deposit.
Welcome Package Matched on Multiple Deposits
With a Welcome Package a casino will not only match your first deposit, but will match your second, third and sometimes even fourth deposit with anywhere from 50% up to 200% or even more in some casinos.
This type of bonus is perfect as you can grow your deposits as you grow confidence with the casino, and know you’ll continue to get rewarded as you deposit more and more. This type of bonus often will contain additional free spins bonuses on each one of your deposits.
Free Spins on Deposit
Online casinos pride themselves on their wide range of exciting and colourful slots. That’s why many casinos will give you up to 200 free spins on select slots when you make your first deposit with them. As these spins are free you’ll have the freedom to try different slots to find the ones you love the most.
No Wager Spins on Deposit
A relatively new type of bonus – “No Wager Spins” or “Fair Spins” are starting to be offered by a handful of casinos. You’ll get a certain amount of free spins for every pound you deposit. These bonuses tend to be lower than the other bonuses out there, but unlike other bonuses, your winnings are available for withdrawal without additional wagering requirements.
No Deposit Bonus
This is where a casino will thank you for signing up with them by giving you a small bonus completely free when you register so you can test the casino out on their own dime.
No Deposit Free Spins
Similar to the No Deposit Bonus, this time around the casino will give you a Free Spins gift when you register with them. These will often be on a one or a few of the most popular slots games so you can discover why they are so popular before you have to deposit a penny.
Bonus Terms and Conditions
Casinos love to reward you with attractive bonuses that can really enhance your enjoyment, but it’s worth noting these bonuses all come with Terms & Conditions, most commonly Wagering, Max Bets and Weighting;
The wagering requirement is how many times you need to bet your bonus before you can be eligible to withdraw your winnings. Typically most bonuses have 30 x wagering, but some casinos will have as low as 5x. No deposit bonuses tend to have the highest wagering restrictions.
Sometimes bonuses will have a maximum bet restriction. This means that you’ll only be able to wager a certain amount on each spin – if they give you a £20 bonus it’s unlikely you can use this entire amount on 1 slot spin.
Additionally, most bonuses will have specific weighting contributions based on the games you’re playing. A player may win big on slots with his bonus and each bet will contribute fully to the wagering requirements, but it’s worth noting on some table games may have a lower contribution amount to the wagering requirements.
