Best Online Slot Games

Although there is a huge amount of choice when it comes to the best online slot games, we have identified some of the UK's most popular online slots. As you can see, casino slot games can be enjoyed with different operators, and these are some of the best slot games with free spins. 

Age of the Gods (Bet365)

One of the best online slots games is Age of the Gods, and we recommend heading to bet365 casino, where you can find several different versions of the game. The original Age of the Gods slot has a 95% RTP, and it’s a high volatile game with 5 reels and 20 lines. 

The features include a Progressive Jackpot, Free Spins and Bonus Games, while there is also the option to play God Of Storms, God Of Storms II, King Of Olympus, Maze Keeper, Wheels of Olympus, Furious 4, Book Of Oracle, Mighty Midas and Apollo Power.

Gonzo’s Quest (Grosvenor)

Gonzo’s Quest is one of the best online slot games, and this NetEnt flagship title has stood the test of time. You can head over to the Grosvenor Casino and enjoy the chance to play different variations, with the original game also flanked by Gonzo’s Gold and Gonzo’s Quest Megaways. One of the attractions to this slot game is that the RTP is nearly 96%, and customers really like the Wilds that can help them land bigger bonuses along the way.

Starburst (BetVictor)

You will regularly see Starburst form part of a new customer welcome package when there are free casino spins available. The BetVictor Casino is one of the operators that houses this hugely popular slot game, with customers loving the playful and colourful element to this title. The RTP is spot on considering it’s over 96%, and it’s a low-volatile game which is great for customers who only want to risk small amounts on their online casino visit.

Book of Dead (William Hill)

The William Hill Casino is a great place to go and check out the Rich Wilde and the Book of Dead casino slot games. Play’n GO is the software giant behind one of the best slot games, with three or more tomb scatters revealing the book and landing a customer 10 free spins. 

There is also a special expanding symbol where you can win more on free online slots and the beauty of this game is its simplicity. There are five reels, three rows and 10 paylines, with customers able to get 5,000 coins for five Rich Wildes.

Fishin’ Frenzy (888 Casino)

Reel Time Gaming has hit the jackpot with the popular Fishin’ Frenzy, and the 888 Casino is one of the operators to get its hands on this popular slot game. There is an RTP of 96.12% when you spin the reels on the original game, with five reels and ten lines giving you the chance to play for free spins and claim Wilds along the way.

Check out other titles in the franchise such as Fishin’ Frenzy Power Slots, Fishin’ Frenzy Megaways, Fishin’ Frenzy The Big Catch and Fishin’ Frenzy Jackpot, where customers can play for a massive progressive.

Kingdom’s Rise (Betfred)

Casino software powerhouse PlayTech launched the Kingdoms Rise suite of casino slot games in 2019, and the games have proved a massive success. Betfred Casino provides customers with the chance to try out the different versions, with a unique rewards system in place that appeals to new and existing casino players.

You’re in a fantasy world with lots of different lands where you can navigate your journey when spinning the reels of the slot machines. Check out the Reign Of Ice, Sands Of Fury, Chasm of Fear, Shadow Queen and Battle Beast as a first port of call.
