Online-Slot.co.uk is dedicated to providing the best online slots reviews. With a focus on UK slot reviews, our team of experts have worked in the online gaming space for close to 40 years combined. We work closely with slot providers so we know the thinking and all the ins and outs of a particular online slot which helps up write detailed slot reviews for you to read.
Comprised of a team of slots players primarily, we’ve played thousands of casino slots both at old and new casino sites in the UK online and at land-based casinos, pubs and arcades. As slot lovers, we look at every detail in the slot reviews to give you a details insight of how the slot game works. Our aim is to arm you with the necessary information so you can pick the right online slot for you. How’s here we review slots:
We only write slot reviews on the best and most reputable slot providers. They all need to be trustworthy and licensed by the Gambling Commission. For example, we cover over 40 providers like NetEnt, Play ‘n GO, Microgaming and IGT (amongst others). New and upcoming providers are also covered if they bring slots that are worthy to the table.
If you take Big Time Gaming for example, they were unknown only a few years ago. Since the introduction of the Megaways engine, they have become a household name and have licensed their innovation to other and bigger providers. In 2020, they released their first Megaclusters slot (Star Clusters Megaclusters). With other providers keen to create their own Megaclusters slots, it will lead to top slots which are innovative and enjoyable.
A slot review will firstly look at the number of reels and paylines. You will mostly find 5 reel slots with between 10 and 243 ways to win. Slot developers are working out new engines and ways to give payouts to players so have more rows, reels and symbols on the reels with some games offering over 1 million ways to win. Providers like ReelPlay have developed an Infinity Reels engine where the number of reels is, well, infinite.
Other slot review details include the stake limits (pretty self-explanatory), the Return to Player % (what you will get back in theory), hit frequency (how often you land a win) and the variance or volatility. The latter is important as some players want to make their balance last as long as possible whilst others are looking for that big payout. This leads up to the max win or max payout which is the most you can win from a particular spin or bonus feature. We also explain how that can be won.
Lastly, we look at whether an online slot game can played across multiple devices. With most games now been made using HTML5 technology, they are all available on iOS, Android and Windows operated devices. Some providers, like 4ThePlayer for example, have developed Portrait Mode versions of their games so they look better and occupy more space on smartphone screens.
Whilst an online slot may have the best bonus features ever made and been creating by a top provider, a slot game needs to be appealing visually primarily. This depends on personal preferences of course with some players liking high definition graphics and animations and others opting for classic slot machines that remind them of an experience at a land based casino or arcade.
Our slots reviews look at the theme (such as ancient Egyptian, Norse mythology, Irish luck) and what they are inspired wise graphically. Some themes will tell a story behind the slot which captivates players which makes them come back for more. A classic example is Microgaming’s Immortal Romance which tells a dark story of love and intrigue. It’s 1 of the most popular slot games ever.
A certain themed slot will have symbols to match. With technology advancing all the time, the quality of the graphics has improved drastically over the last few years. This lead to an immersive playing experience and provides much more than just a slot game. The soundtrack/audio is an important factor as this reinforces the theme and adds to the playability.
Whilst classic casino slots had 1 or 3 paylines and a limited number of paylines, newer slots have various ways to win. As a result, bonus features are a vital part of a slot’ appeal. Most slot games offer free spins of some variety and wild symbols.
The most popular slots come up with some unique and innovative to make them stand out from the crowd. For example, the Megaways engine from Big Time Gaming unleashed bonus features never seen before. Other providers like NetEnt and Play ‘n GO regularly introduce new types of wild symbols into the mix which add to the excitement of a release. Our slot reviews look at all bonus features, what they can pay out and the mechanics and engines behind them.
At the end of our slots reviews, we combine all the elements above and bring it together to give our feedback on the slot game. This can be good or bad as not all slots are great or amazing. Reputable providers still release slots that are simply unappealing. Whilst we tend to focus on the best slot reviews, we compare to similar titles and provide our recommendations if you’re looking for games that offer a similar bonus feature or theme.

With a UK focus, new slots casinos are reviewed more critically than established brands as they don’t have the longevity and reputation of older sites. We look at anything new they bring to the table including specialised promotions, new slot providers and slot games, more payment methods and mobile apps/sites.
We also go behind what you see and delve into the companies behind these new slots sites. It’s important to know where a new slot site is a white label, a new brand from an established operator or a brand new site with a good reputation in other markets.
