How to Pick the Best Slots

Picking the best online slots casinos in the UK is hard work, which is why we've done it for you. We've spent many hours researching and providing you with accurate information and reviews of ‘best online slots casinos’ around the Web. To help us do this, we've developed and improved our own ratings system. This system is based on criteria casinos need to meet before we recommend them to you. Here are just some of the factors in our criteria. 

  • Safety and security: Our recommended casinos have security in place to protect your personal and financial data.
  • A large slots selection: An extensive games catalogue provided by the industry's top games providers is essential.
  • Bonuses and promotions: Fair and generous bonuses are also on our strict criteria for the best online slots casinos around.

Safety and Security

Safety and security is about making sure that your personal and financial data remains safe. The first thing we check is a casino’s legitimacy by looking for a valid licence. Possession of a licence from the UK Gambling Commission tells us that the site is regulated by an official authority. We also want to know whether or not it’s regulated by an independent testing agency like eCOGRA. And we look for an up-to-date SSL encryption certificate, which is an important security feature, as it protects your personal data.

A Large Slots Selection

A good selection of slot games is essential for any top slots casino. The games library should include progressive jackpot slots, for example. These games pay out huge winnings, so they can be exciting to slot players. The option to try out games for free is another feature we look for, as being able to sample a casino and its games before you play for real money is a huge plus. Slot games are typically developed by specialist casino game developers like Microgaming and NetEnt. Typically, if a casino offers games from the best developers in the business, it means that this gaming website is professional enough and aims to provide an entertaining gaming experience to its players.

Bonuses and Promotions

Bonuses and promotions that are fair and provide our players with good value are next on our list. A generous welcome offer makes for a great start to any online slots casino. Bonuses that check the box for us include deposit bonuses, slots sign up bonus no deposit offers, free spins, and cashback offers. We also insist on reasonable terms and conditions for us to consider a slots bonus to be fair.  

Mobile slots offer the same functions, features, and gameplay as the desktop version does. Compare your options with Mr-Gamble.

Top Online Slots Bonuses

An online slots bonus is a free gift offered by slots casinos to incentivise you to play their games for real money. As a result, there are many casino bonuses to choose from. Here are the ones you should definitely be aware of.

  • Sign up bonus: A welcome bonus slots offer is often the most generous promotion and among the most appealing aspects of signing up to a casino.
  • Match bonus: Where the casino matches your deposit up to a certain percentage, essentially giving you free funds to play with.
  • Free spins: Try out one or more slots for free while also becoming familiar with the casino's layout and features.
  • No deposit bonus: Claim either free spins or a small amount of money to play with simply for creating an online casino account.

Slots Sign Up Bonus 

The sign up bonus is an offer that the casino makes to encourage you to create an account and give them a try. Also known as a slots welcome bonus, it’s often comes in the form of a match deposit, where the casino matches your deposit by up to 100%. There’s a limit on the amount, but if you claim a casino slots signup bonus that offers a 100% match bonus of up to £250 and you deposit the maximum qualifying amount, that’s £‎500 in your account balance to start your slots journey with. You'll find the best slots welcome bonus no wagering promotions offered by a number of our recommended casinos.

Match Bonus

A match bonus the same type of bonus we have described in the section above. However, match bonuses aren’t limited to sign up offers. They also come in the form of reload bonuses. You can claim these as an existing player while making a deposit into your account. The match bonus isn’t typically as generous as the welcome offer, matching your deposit by around 50-75%, as opposed to the 100% you often see with a welcome offer. 

Free Spins are free plays for slot games that UK online casinos give to old and new players, especially when a new slot game by a popular developer is released.

Free Spins 

Free spins bonuses are your free chances to play a slot for a set number of times without having to spend your own money. They’re often given on one or a limited number of slots. For example, when a casino wants to promote a particular slot game or software developer. It is usually a great way to try new games and their bonus features.

No Deposit Bonus 

Free bonus no deposit slots are a risk-free way of trying out a casino. A slots bonus no deposit promotion is often in the form of free spins, as described above. It can also be a nominal amount of money awarded to you simply for creating an account with a casino.

Many casino players favour a slots welcome bonus no deposit offer because it's free money and the fact that they don't even have to fund their account to play no deposit bonus slots. You'll find the best slots no deposit online bonuses at our recommended casinos on this page.
