How We Found the Best Online Slot Sites in the UK

Game Selection

They say variety is the spice of life, and the same applies to casino games online. When testing and rating UK online casinos, we look at the number of slot games, the gameplay quality, and the software companies that provide them. We review the different categories on offer, the themes, and bonus features.

Bonuses and Promotions

While reviewing the bonuses and promotions at online slot casinos, we look at the size of the bonus as well as the terms and conditions accompanying them. Of course, each bonus on this page is available to use across many slot games at the casinos.


One of the requirements for online slot casino sites is to have a wide range of secure payment options. Money has to move in and out of your account, making this an important area to consider when reviewing a casino.

We check the available options for withdrawals and deposits, the payout limits, and the time it takes to process the transactions. We also review other conditions necessary for you to meet in order to complete a transaction, including fees and the provision of extra documents.

What Makes PlayOJO the Best Site to Play Slots Online in the UK?

Guide to Playing Online Slot Games in the United Kingdom

What Are Wild and Scatter Symbols?

Wild and scatter symbols are part and parcel of modern-day slot games in the UK – they stand to increase your winning chances and provide you entry into the slot’s bonus round.

A wild symbol is much like a Joker in a pack of cards; it can replace all the other symbols (besides the scatter) to form winning combinations. Scatter symbols, on the other hand, are used to trigger bonus rounds when they appear “scattered” anywhere along the reels.

Which Are the Most Popular Progressive Jackpot Slots in the UK?

The most popular progressive slots that you can play in the UK are Microgaming’s Mega Moolah, NetEnt’s Mega Fortune, and Playtech’s Age of the Gods slot series.

Is It Possible To Play UK Slots Online for Free?

Yes, you can play slot games online for free. Most UK online casinos will give you the option to play slots for free before wagering real money – even without an account.

However, winnings accumulated while you play online slots in free mode cannot be withdrawn. Also, not all UK gambling sites offer this feature.

What Does RTP Stand For in Slot Games?

RTP stands for Return To Player percentage. It is a theoretical figure found in all online casino slots, and it shows you the expected return for every $1 you wager.

For example, a slot game with a 90% RTP figure means that you can expect a theoretical return of $0.90 for every $1 wagered. A 98% RTP means a return of $0.98 for every $1 wagered. The higher the RTP, the better the chance of a handsome payout.

Is There a Strategy to Win Online Slots in the UK?

The outcome of online slots is 100% random and unpredictable, which means no strategy will help you win every time you are playing online slots.


However, a proper bankroll management plan will go a long way in helping you improve your winning chances.

Are Online Slot Games the Same As the Ones at Land-Based Casinos?

Yes and no. If you play the Book of Dead slot online or in land-based casinos, it will have the same winning chances at both places.

However, the advantage of playing slots online is that you’ll find numerous online slots that are not available at land-based casinos, and most of them will have higher RTPs because of the lower overhead costs of UK online casinos compared to their brick-and-mortar counterparts.
