Top 10 Real Money Casinos for Slots in UK

For all the hoopla that comes with the average modern UK online casino, the bread-and-butter staple of all that is good and wholesome is the common-or-garden Slot game. Beloved of millions of UK gamblers long before the internet was even invented, the modest slot is at the heart of all wagering operations. Casinos must offer a balanced and interesting curation of onlien slots or they will simply fail to make an impact in an increasingly-competitive market. And it isn’t just about numbers; clearly variety is required, but quality, above all else, decides how popular a slots collection will be. With ever more software companies starting up, pushing the established behemoths of the industry to bigger and better offerings, casinos have a fertile landscape from which to select their games.

Here is our guide to the best UK casino apps offering top real money slots on mobile devices. Such sites include Casumo, bet365, Mr. Q slots, Amazon slots, and Grosvenor casino. View the best promos, including free spins for selected slot games for 2023, right here.

UK casinos with top slot games and bonuses overview

Rainbow Riches

Launched in 2019, Rainbow Riches is named after the popular series of games, usually Celtic-themed, that have long been a hit with players. It is an example of a growing trend to create bespoke casinos for one specific type of game, but it also offers plenty more besides. Rainbow Riches Cluster Magic is easily the most popular slot on the site and it is easy to see why. A 5-reeler, it gives punters the chance to collect bonuses and expand the game to an 8×8 grid, with huge potential for big wins. The famous Infinity Spins Feature can unlock 250 Free Spins. 

Rainbow Riches Leprechaun’s Gold is another of the most-played slots and features 50-win lines, with 5 and 7-reel bonus rounds. The game looks great, with beautiful green panoramas and ambient sounds. Great for playing on the App. There are over 300 slots on the sites like Rainbow Riches UK, provided by stand-out software firms like IGT and WMS and, with over 50 Live Casino games as well, Rainbow Riches unsurprisingly was an award winner in 2022.

Monopoly Casino

Named after the legendary board game, Monopoly Casino arrived in 2015 and has quickly become one of the most popular slot sites in the UK. The App, available on iOs and Android, is superb and carries over 500 games. Monopoly Paradise Mansion is the signature slot and offers dual bonuses and a 10,000x your stake size maximum win. With 20 pay lines and the Monopoly Community Chest Bonus, this game is a hit with players. The 96% RTP is very decent too.

Monopoly Rising Riches is a Top 10 slot on the site and features Raining Reels, Scatters and a Multiplier of up to 20x your coin size. This 25-line game rewards consecutive wins and gives you the chance to watch the Property Meter rise. Double Bubble Jackpot slot is also available, along with a host of other top slots (notably Raging Rhino, Tiki Island and Montezuma) to round off a high-class slot experience. 

Lucky VIP Casino

Lucky VIP has over 800 games on site, with over 100 slot jackpot offerings. Launched in 2015, Lucky VIP has an overall Return To Player (RTP) ratio of 95%, meaning players get great value, as well as a fantastic slot collection. There are Megaways games, a good number of Slingo iterations and all are neatly curated into easily-accessible sections, like “Top” and “Featured”. There are classics nestled alongside new innovations. One of the most-played slots at Lucky VIP is Esqueleto Expolsivo 2. It is a Mexican Day of the romp set on a 5×3 grid. It is a high-volatility game with a 5,000x maximum win and the visuals, music and sound effects are all top-notch. 

Dolphin’s Pearl Deluxe is another Lucky VIP favourite since 2019. A 5-reel, 10-payline player, it features an underwater set, complete with sea creatures and strange aquatic happenings. There are Scatter symbols, Free Spins and the Wild symbol is the smiling Dolphin of the title. The blend of slots and Live casino games at Lucky VIP is superb and for those players who seek innovative games alongside slot classics, they should look no further than Lucky VIP.

Types of Real Money Online Slots to Play at UK’s Best Casinos

Slots come in all shapes and sizes, but we can nevertheless define certain “types”. 

Classic Slots

Classic slots are direct descendants of the one-armed bandit, so popular in pubs and clubs throughout the last century. Based round a 3-reel format, they remain popular due to their relative simplicity, speed of play and ability to plug into and offer big, Progressive Jackpots. Play classic slots for real money with free spins bonus at these casinos: Unibet (400+ slots), Spin Rio (£200 match bonus) and Magic Red.

5-reel Slot Games

5-reel slots are also referred to as “video slots” and are a natural fit with the high-def graphics and technical innovations of the last decade. They have more paylines, bigger potential jackpots and often come with enhanced sounds and visual accoutrements. 5-reelers are probably the most popular slots across the online casino world. The best 5-reel video slots with extra bonus rounds and bonuses are at bet365 UK Games and new Rialto website.

Dolphins Pearl Deluxe is one of the mostpopular online slots at UK casinos. Play this 10-line, 5-reel Novomatic game for real money at Lucky Vip.

Megaways Video Slots

Megaways are a type of slots that were originally developed by Aussie software outfit Big Time Gaming and feature random reel modifiers that can spice up the more traditional games. They are growing fast, so much so that operator Gamesys launched the Megaways casino in 2021 (sign up, get bonus, play modern slots with high RTP).

Jackpot Slots

Daily Drop Jackpot games are another slot innovation that are growing in popularity. With a guaranteed top prize to be won every day, they make a nice alternative to the bigger Progressive pots that may build for days and weeks on end. Also, the stakes required to join a Daily Drop Jackpot are much lower than on Progressive ones. 

There are many other riffs and variations on slot games and the software companies are constantly innovating, so that is only an overview of what punters can look forward to, slots-wise, in 2023. Companies like Play’n Go, Evolution, Pragmatic Play, Nolimit City, NetEnt, Red Tiger and Yggdrasil, to name but a few, are churning out games at a huge rate. More importantly, many games are now being designed specifically for Apps, so punters can play on-the-go. This means there is no drop-off in quality from desktop versions and an ever-growing level of technical innovation, which should lead, hopefully, to greater player satisfaction.
