The Best Online Slots in the UK: 9 Games You Won’t Want to Miss Out On

The sheer quantity of online slot games on offer can be daunting. From traditional fruit slots to branded video slots, there’s a style to suit everyone’s taste. At Beat That Deal, we’ve tried and tested the UK’s most popular slots and brought together the nine we rated highest.

How we judged the UK’s best online slots

To make the cut, the slot games we looked at had to meet several criteria. Firstly, the software had to perform well, offering a smooth user experience and high-quality graphics. We were also looking for games that didn’t get boring quickly. To deter boredom, the game needed to have exciting bonus and free spins features. The more varied the bonus features, the more engaging the game.

We also considered the value of potential wins. In some cases, we spotted games with progressive jackpots just too good to be missed. Meanwhile, some of the UK’s best online slots simply have a sound mid-level variance to let you win a little often.

1. Jurassic Park

Software: Microgaming
Fun factor: 5/5
Theme: Dinosaurs in the prehistoric jungle
Return to player: 96.76%

Transport yourself back to a prehistoric world where dinosaurs roamed the landscape in the Jurassic Park slot. Based on the classic film, this game has some stellar graphics that truly immerse you in the Hollywood-inspired theme.

There are five free spins features, each with their own wild reels, mystery multipliers and winning wilds. The biggest win is available in the T-Rex Alert Mode bonus feature, where you can win back 6000 times your stake.

Four of the free spins features only become available once you’ve activated the free spin mode 25 times. So, play this game when you want to sit down for a longer session. Once started, you’ll have to tear yourself away from Jurassic Park’s quality visuals and thrilling features.

2. When Pigs Fly

Software: NetEnt
Fun factor: 5/5
Theme: Pigs in space
Return to player: 97%

When Pigs Fly is one of the UK’s best online slot games thanks to its cool graphics. The cartoon-style animations will put a smile on your face and the catchy theme tune gets you in the gaming zone.

If you play the slot, you’re looking out for the ‘When Pigs Fly!’ symbol. This symbol returns 1000 times your bet when you get five together on a payline. There’s also an excellent re-spin feature, where you can win up to five free spins. The re-spin feature is especially exciting because it activates new positions for symbols. The additional positions create new winning combinations, so you have a better chance of getting lucky.

When Pigs Fly is one of the best online slots to come out of NetEnt. By combining a wacky theme with quirky spin features, the game balances entertainment value with reasonable returns. The medium variation game lets you bet 50p – £100 per spin.

3. Game of Thrones

Software: Microgaming
Fun factor: 4.5/5
Theme: Dark medieval
Return to player: 95% (15 payline version)

There are two versions of the Game of Thrones slot game: one 243-way slot and a second version with 15 paylines. Both are good, but the different set up does affect the feel and variance of the game, so opt for one that suits your preferences.

The game has a free spins feature where you pick from one of the four Houses of Westeros (Targaryen, Lannister, Stark and Baratheon). Each House gives you a set number of free spins, a multiplier and a number of stacked symbols. The four options prevent this game from getting repetitive and gives you the chance to experiment with how the different offers affect your win rate.

Fans of the television series will enjoy playing this slots adaptation. Admittedly, the game’s graphics are basic, but this is most likely intentional; anything more elaborate would jar with the dark, epic theme.

4. Steam Tower

Software: NetEnt
Fun factor: 5/5
Theme: 19th century
Return to player: 97%

In the Steam Tower video slot, you get to be the knight in shining armour and save the princess from the dragon. There’s also a fantastic free spins feature that activates a multiplier of up to x7 on your winnings.

The five-reel slot has 15 paylines and you can play it for as little as 15p per spin. There are four high-value symbols – the tower top, the princess, the hero and the golden eye of the dragon. The hero symbol will grant you access to the bonus feature.

Watch out for the stacked wilds in this game as they’re what will unlock free spins. Also, look for the grappling gun symbol, which simultaneously releases free spins and takes you up to the next level in the tower.

5. Big Bad Wolf

Software: Quickspin
Fun factor: 4.5/5
Theme: Three Little Pigs Fairytale
Return to player: 97.34%

If you’ve played and enjoyed games such as Gonzo’s Quest and Rook’s Revenge, you’ll like Big Bad Wolf. Big Bad Wolf is based on the fairy tale (you know, where the wolf huffs and puffs to blow the piggies’ houses down).

As well as the beehive, which is the regular wild, the pig symbols become wilds after a set number of wins. The more wilds you activate, the better your chances of winning. You’ll also want to look out for the wolf – this is a scatter symbol that activates multipliers.

The swooping symbol characteristic of the game is a bit love it or hate it. Rather than spinning the reels fall into place (like in the Candy Crush mobile game if you’re familiar with that). Even with this unusual effect, the game’s ability to balance a high RTP with substantial wins gets it a place in the UK’s best online slots.

6. Rainbow Riches

Software: Barcrest
Fun factor: 4/5
Theme: Irish folklore
Return to player: 95%

This well-known slot game is popular in the UK and there’s a good reason why. With some of the best bonus features of any slot game, Rainbow Riches has plenty to liven up your gaming experience.

There are three bonus features: the Road to Riches bonus, the Wishing Well bonus and the Pots of Gold bonus. Each bonus can multiply your stake up to 500 times, and you’re going to feel very smug if it does.

Rainbow Riches sees Barcrest move from the physical slot machines found in bookies to online slots. Anyone who’s a fan of the traditional fruit machine-style of game will enjoy trying their luck on Rainbow Riches.

7. Age of the Gods

Software: Playtech
Fun factor: 4.5/5
Theme: Greek mythology
Return to player: 95%

The Age of the Gods online slots replaced the well-liked Marvel games that Playtech had to withdraw. Centred around Greek mythology, ‘Age of the Gods’ is one in a series of games that includes ‘Age of the Gods: Furious Four’ and ‘Age of the Gods: Prince of Olympus’.

As you play, you’ll see the faces of iconic Greek gods, such as Zeus, flash up. To win, you need to land three gods on an active payline. Athena (the Goddess of War) is the highest paying symbol – land five of her on a payline and you’ll win 1000 times your bet.

Other symbols you’ll want to cheer on include the laurel wreath, which is the wild symbol in the game. You’ll also want to root for the Age of the Gods game logo; this is a scatter symbol that unlocks free spins.

8. Beach Life

Software: Playtech
Fun factor: 4/5
Theme: 1980s seaside
Return to player: 97%

Want to escape to the seafront and surround yourself with ice creams? Beach Life is a classic game with a retro look and feel. It’s been around for a while, but its happy simplicity gives it a timeless sense of fun.

When playing Beach Life, your aim is to win the progressive jackpot. So, you need to look out for the sun symbol – this is the wild that replaces all symbols other than scatter and bonus ones.  Get five sun symbols on a winning payline and you hit the jackpot.

Although Beach Life doesn’t perform as well as some newer games for bonus features, you will activate a bonus game by landing consecutive sunken treasure symbols on a payline. Your screen will then fill with treasure chests; all you have to do is pick three and reveal the bonus amount inside.

9. Arabian Nights

Software: NetEnt
Fun factor: 4/5
Theme: 10th century Arabic
Return to player: 95.6%

If you’re feeling lucky (and rich) Arabian Nights is a fabulous choice. It’s one of best online slots in the UK because it has a progressive jackpot that pays handsomely. All you need to do is land five Arabian Nights symbols on a payline.

Although it’s a jackpot game, the slot does have a free spins feature. The feature activates a multiplier based on the amount of Aladdin lamps you hit – the more lamps, the higher the multiplier. You’ll then get started with 15 free spins, which increases if you continue to find lamps.

If you enjoy progressive jackpots, Arabian Nights offers one of the biggest. What lets the game down is the minimum bet – £5 a spin – so you’ll have to reign yourself in a tad.
