The live games have all been supplied by the ‘big three’: Playtech, Evolution Gaming, and Pragmatic Live.

Apart from the amazing game library, it also stands out thanks to the bonuses. As a new player, you can score up to £100, which also comes with 100 bonus spins that can be used to play Jackpot City Gold Blitz, one of its many exciting original games.

The famous Hippodrome Casino has made its way to the online casino domain, and now it sits in the number two spot in our rankings of the best casino sites in the UK.

New players at Hippodrome Casino will get both a 100% up to £100 deposit match and 100 bonus spins. It’s great that we get the best of both worlds like this, as it means that more games can be enjoyed.

What makes this welcome bonus even better is the lack of wagering requirements on the winnings for the bonus spins. You won’t have to play through them once. This could save you plenty of time that you’d probably rather be spending playing the games.

And what games they are as well. Hippodrome Casino, like Jackpot City, has about 500 games to play. A little over 10% of these are live games, including some high RTP options.

Best Paying Game at Hippodrome Casino: Pragmatic Play Live One Blackjack [99.28% RTP]

My Verdict:

Overall, I can say that Hippodrome Casino has one of the best online casino bonuses in the UK at the moment. This, combined with some high payout games, means that this casino has the chance to be one of the best for your bankroll. That’s always good news to hear.

Plus, the welcome bonus at Hippodrome Casino is not the only way to get bonus cash and bonus spins to play with. Existing players can also grab more bonus cash and further bonus spins through the ongoing Daily Deals offers. Then, there are further loyalty bonuses for all players.

3. PlayOJO – Best Mobile Casino Site in the UK

First deposit only. 50 Free Spins on Big Bass Bonanza slot. Free Spin valued at £0.10. Excludes players in N.I. Irregular play may lead to the removal of rewards. OJO’s Rewards and Game Play policy applies. Note that full T&Cs apply.

Pros:

• 50 bonus spins on signup with no wagering
• Loads of extra bonus Kickers spins

The lack of wagering requirements on the bonus spins for the PlayOJO welcome bonus is a game-changer. They allow you to cash out anything you’ve won with the bonus spins right away. This could, in theory, save you quite a few hours of your time.

Plus, the bonus spins are for a great game in Big Bass Bonanza by Pragmatic Play. This is one of the most famous online slot games ever made, so you should have a lot of fun using up your spins.

Once you’ve used these welcome spins, you can come back for a lot more ‘Kickers’, PlayOJO’s daily rewards for existing players. It should also be noted that a number of the online slot games at PlayOJO have bonus spins and bonus rounds that you can use to hopefully get even more bonus spin action.

Best Paying Game at PlayOJO: Joker Strike [98.11% RTP]

My Verdict:

Bonus spins are awesome for online slot game fans in the UK. They allow you to try out some slot games and potentially take home some winnings without having to spend as much money. PlayOJO is the best place to get hold of them.

It’s no surprise that this online casino has won so many awards in the UK over the years, such as ‘EGR Operators 2023 Mobile Casino of the Year’ and ‘EGR Operators 2023 Slots Operator of the Year’.

Did you know? PlayOJO is also one of the best Canadian casinos online.

4. Betway – Best UK Online Casino for Slot Games

New customers only. Opt-in required. 100% Match Bonus up to £50 on 1st deposit of £10+. 50x wagering & game weighting applies. Debit Card deposits only (exclusions apply). This offer is valid for 7 days from your new account is registered. 18+. BeGambleAware.org. Note that full T&Cs apply.

Betway is one of the most famous online sports betting brands in the UK, but did you know that it is also the best place to play online slot machines?

Pros:

• Features more than 1,300 online slot games
• Wide range of slot game styles and themes
• Excellent mobile experience
• Slots by NetEnt, Microgaming, and Pragmatic
• Dedicated sports betting section

Cons:

• Could use a few more bonus spins bonuses
• Mobile experience is not the best

If you are a fan of slots, there are a few sites in the UK that deliver an experience as good as Betway. It is home to over 1,300 slots, high RTP games, and regular bonuses and tournaments for slots players.

• Slots, Poker & Other Games: 4.7/5
• Bonuses & Other Offers: 4.4/5
• Payment Methods & Payout Speed: 4.8/5
• Customer Support: 4.6/5
• User Experience & Design: 4.8/5

>> Match your deposit up to £50 [Betway]

The total number of online slot games at Betway at the time of writing is more than 1,300. And considering the rate at which new games are added to the ranks, we think it’s fair to say that there is an abundance of options here.

The diversity and the quality of the games really stand out to us as well. You can play low-variance games, high-variance games, bonus spins games, Megaways, and jackpots – you name it, and they all come from established providers such as NetEnt and Microgaming. Apart from slots, it also features dozens of online blackjack games, roulette, baccarat, and more.

Betway is also the best place to play online slots on a mobile device. Its casino app has some of the highest scores we’ve ever seen.

You can get a fair deposit bonus to play these slots at Betway as well. This is a 100% up to £50 deposit match. It’s not as big a bonus as some of our other top picks, so it doesn’t quite justify the 50x wagering requirements, but we think it will be worth grabbing for most players anyway.

Best Paying Game at Betway: 5 Lions Megaways 2 [96.5% RTP]

My Verdict:

Being the king of slots as a casino in the UK is quite prestigious, considering how much players in the country love these games. Betway accommodates all types of slot fans with its huge range of themes, reel mechanics, bonus rounds, and more, and they’re all awesome.

Payouts are made in the blink of an eye. It’s instant for most of the payment methods, so you won’t have to worry about your winnings waiting around in limbo.

5. Grosvenor – Best UK Online Casino for Table Games

New customers only. Min deposit £20, PayPal & Paysafe excluded. £30 bonus (x30 wagering) on selected games. Max wins £2K. Note that full T&Cs apply.

The number one place for table games in the UK is Grosvenor; it also features generous bonuses, a mobile-friendly site, and other exciting features.

Pros:

• Live games streamed from land-based casinos
• Further live games by Evolution Gaming
• Play with a 150% deposit match as a new player
• Unique live game shows by Playtech and more
• Famous and trusted UK casino brand

Cons:

• Bonus amount for new players is capped at £30
• Could benefit from some more modern slots

It might be our #5 pick, but Grosvenor is one of the most famous brands out there. It also has a land-based casino in the UK, which is very popular among players. Let’s take a closer look at it.

• Slots, Poker & Other Games: 4.7/5
• Bonuses & Other Offers: 4.3/5
• Payment Methods & Payout Speed: 4.6/5
• Customer Support: 4.6/5
• User Experience & Design: 4.6/5

>> Deposit £20 and play with £30 bonus [Grosvenor]

This casino site has utilised the land-based casino heritage of the brand with its choice of live dealer games. We love the fact that you can play along with the live dealers based in the casinos across the country, such as in Nottingham and Southampton.

These are not the only live dealer games you can play at Grosvenor, though. It’s also possible to play more conventional games from huge brands such as Evolution Gaming. This means high RTPs, fun gameplay, and unique titles like Snakes & Ladders Live and Busted or Bailed.

Best Paying Game at Grosvenor: Playtech Live Roulette [97.3% RTP]

My Verdict:

Live casino games can capture all the fun of a land-based casino if they’re done right. It just so happens that pretty much all of the live casino games at Grosvenor are done absolutely right. I also loved their table games library, full of exciting options from leading providers.

There’s a reasonable welcome bonus that you can get when you first sign up here as well. This is a £30 batch of bonus cash that you’ll get with your first deposit of £20.

Bonuses & Promos

Casino bonuses are key in the UK, as they allow you to get some bonus cash or perhaps some bonus spins to play more. So, bigger bonuses are great to see, but only if they come with terms and conditions that are fair to players.
