As the UK online gambling world continues to boom, it can be difficult to figure out which platform is the best for your betting needs — or even more importantly, which ones are trustworthy.
That’s why we decided to help:
Our industry experts combed through the best gambling sites in the UK and, using first-hand experience, ranked and rated them in a variety of key benchmark categories.
PlayOJO took the top spot on our list, but all of the online betting websites we ranked offer something unique to British players and are also worth checking out.
Let’s take a look!
Best Online Gambling Sites in the UK
- PlayOJO: Best overall
- Kwiff: Best for sports betting
- FansBet: Top pick for football betting
- Mr Play Sport: Best variety of sports markets
- Leo Vegas: Best for live casino games
- ZetBet: Best for live sports betting

1. PlayOJO - Best Gambling Site in the UK Overall
18+. New, ID Verified players only. 50 bonus spins credited to new players. No wagering requirements. All bonus wins paid in cash. No maximum win. Note that the full T&Cs apply.
- 50 bonus spins with no wagering
- 3,000+ casino games
- Hundreds of RNG table games
- Uncapped bonus winnings
- 100+ live casino games
- Ideal for bingo players
- Doesn’t offer sports betting
PlayOJO is the winner today, boasting a massive catalogue of over 3,000 games and 50 bonus spins with — wait for it — zero wagering requirements! This casino was launched back in 2017 and is fully licensed by the UK Gambling Commission.
Casino Games - 4.8/5
PlayOJO is loaded with over 3,200 casino games from 57 different providers. If there's a specific online casino game you're looking for, and you can't find it here, chances are it doesn't exist.
The focus is clearly on slot games, but that doesn’t mean that table options are sparse; quite the contrary — you will find more poker and blackjack choices here than at nearly any UK casino.
This website offers an extensive collection of blackjack, baccarat, poker, and roulette games. With over 30 options each for blackjack and baccarat, 17 different poker variations, and 40 roulette options, there's something for everyone.
To date, PlayOJO has paid out over £180 million to players across the globe, with one person taking home £3.5 million from a single slot game. If you're looking for some of the best online slots in the UK that offer 96% or higher RTP, look no further than PlayOJO.
Unlike most online casinos, PlayOJO also has a dedicated bingo section. We could easily argue that this gambling site is also the best platform for UK bingo players.
Finally, you can play more than 130 live dealer games.
So much praise and not a single negative. Well, there is one — PlayOJO doesn’t offer sports betting, which might be a dealbreaker for a lot of UK players.
Welcome Bonus - 4.8/5
As a new player at PlayOJO, you are eligible to claim 50 extra spins on the slot game Book Of The Dead. The extra spins come with zero wagering requirements, so virtually any winnings you get are yours to keep. And you’re not limited to how much you can win, too.
To claim the extra spins, you’ll need to deposit at least £10.
If you're a bingo player, you can score 50 bingo tickets, 10 bonus spins, and 5 days of Free Bingo instead.
We would also like to see a classic deposit bonus at PlayOJO in the near future, but we can’t really complain.
Mobile Compatibility - 5/5
PlayOJO's mobile version is fully compatible with both iOS and Android devices. You don't need to download an app, simply log in via your mobile browser and enjoy the same selection of games as you would on a desktop computer.
The website is optimised for all types of handheld devices, ensuring that loading times are minimal and that no games crash.
That said, you can still download a dedicated app for Android and iOS. We tested the software on multiple smartphones and had no problems whatsoever.
2. Kwiff - Best UK Gambling Site for Betting
18+, new players only. Min. deposit of £10 required to qualify. £20 surprise bet issued when you wager at least £10 on any sport or match with odds greater than or equal to 1.50 as your first-ever bet. Deposit method restrictions apply. Note that the full T&Cs apply.
- Excellent sports betting platform for beginners
- “Kwiffed” odds (enhanced odds for certain matches)
- Useful stats provided during in-play events
- Random supercharged odds
- Over 100 live casino games
- Impressive variety of online slots
- Kwiff’s surprise bet is assigned to a random match
Kwiff debuted in 2015, and they have remained a trusted gambling brand ever since. UK players like Kwiff because of its excellent betting odds on all major sports, the supercharged odds, and the amazing online casino, including over 100 live dealers.
Kwiff offers convenient banking methods, including debit cards, PayPal, and ecoPayz, so it’s easy to get started here.
Sports Betting Options - 4.7/5
As far as major sports are concerned, Kwiff is an excellent online sportsbook. Whether you are wagering before a match or live betting for exciting in-play action, you will get some of the best odds for football, cricket, rugby, and all the popular UK leagues.
With over a dozen options to wager on, including horse racing, Kwiff may not be the best platform for bettors who enjoy niche sports or novelty markets.
But because they have a strong market for all the popular sports (including eSports) and a simple user-friendly interface, this is a great bookmaker if you are a rookie or primarily bet on just the main markets. Plus, each bet you place could get Kwiffed.
What do you mean by “Kwiffed”, you ask?
Well, with every bet you place in the sportsbook, the odds could randomly get supercharged. This booster hits randomly and ranges from 5x all the way up to 2000x the initial odds.
Casino Games - 4.6/5
With nearly 500 total games to play, this online betting site provides over 300 mainstream slots and over 100 live casino games, and the table games really pop in this online casino.
Some stand-out table games include I Luv Suits Online Poker, 10p Roulette, Solitaire, Mini Baccarat, 3-Hand Casino Hold’em, and Double Exposure Blackjack, to name just a few.
For live dealers, you will find dozens of tables for all the traditional options (blackjack, roulette, and baccarat) and dozens more for unique games.
Some noteworthy titles here include Lightning Roulette, Monopoly Live, Deal or No Deal, Crazy Coin Flip, Baccarat Squeeze, and over three dozen tables for Speed Blackjack.
Welcome Bonus - 4.6/5
When you sign up with Kwiff and place a £10 wager as your first-ever bet with odds greater than or equal to 1.50, the online bookmaker will give you a £20 surprise bet.
The surprise bet is auto-generated using an algorithm and appears directly on your bet slip. This bonus bet could be on any sport — is eligible to randomly get Kwiffed — and you don’t have to worry about wagering requirements.
Mobile Compatibility - 5/5
The primary PC sports betting site has a clean design and is very easy to use, but the mobile options are even more impressive at Kwiff.
The mobile browser site functions like a gambling app, making it easy for bettors to quickly find and bet on the sport or match they are interested in.
You even have the option of downloading the Kwiff mobile app for iOS and Android devices – but this is purely optional since the betting site offers such an amazing in-browser mobile experience.
3. FansBet - Best Gambling Site in the UK for Football Bettors
18+, new players only. Use bonus code SPORTS on your first qualifying deposit of up to £100. The wagering requirement is 12x the deposit. Each qualifying bet must be at odds of 1.80. Note that the full T&CS apply.
- Over two dozen international sports
- 120+ football leagues
- Generous 100% sports bonus
- Massive live casino, 200+ games
- Dozens of low-stake live games
- Great collection of Megaways & Mega Moolah slots
- Fewer traditional games than most UK online casinos
Launched in 2017, FansBet is one of the new betting sites UK offers. This sportsbook has built a reputation for offering more football leagues and live casino games than many other betting sites.
Betting Options - 4.8/5
With nearly 30 international sports and entertainment markets to bet on, a massive number of props and alternate lines for nearly every match, and in-play live betting options — few online bookmakers in the UK offer more betting options than FansBet.
But it’s the football selection that steals the show. From Friendly matches to Finland’s Ykkonen to Scotland’s League Two, on average, this betting site offers over a massive 120 leagues with over 1,500 daily games.
Casino Games - 4.2/5
When it comes to slots and table games, there are just over 100 options to choose from, and the vast majority are slots.
While you will not find the great number of slot options at FansBet that you have at PlayOJO, this betting site does offer a great assortment of Megaways and Mega Moolah games, all of which offer very large jackpots.
And with over 200 selections and dozens of low-stake options, this is one of the best live casino sites in the UK.
Some stand-out live dealer games include Salon Prive Baccarat, Gonzo’s Treasure Hunt Live, First Person Craps, and the exciting online poker game Two Hand Casino Hold’em.
Welcome Bonus - 4.7/5
If FansBet didn’t have the best football markets — they would have ranked for the best sports bonus. New players can score a 100% sports bonus of up to €200 by using the bonus code SPORTS on their first-ever deposit.
The rollover for this offer is 12x, and you can only wager on odds of 1.80 or greater with your free bets.
Mobile Compatibility - 4.6/5
While there is no mobile app, you don’t really need one because FansBet is one of the top mobile casino sites.
Mobile players can enjoy all the casino and sports betting offerings, and the FansBet sportsbook is well-designed and super-fast for users to swiftly bet online.
4. Mr Play Sport - Best Market Variety of any UK Online Gambling Site
18+, new players only. Min. deposit and first bet requirements are £10 or more. Qualifying bets must have odds of 2.00 or more and must be singles and straight accumulators. Winnings of the £10 free bets can be cashed out right away and exclude the free bet stake. Note the full T&Cs apply.
- 30+ sports
- Competitive betting odds
- Nearly 1,000 daily sports games to bet on
- Useful sports betting magazine
- 500+ casino games
- Large selection of payment methods
- No online bingo
- Slim variety of table games
Self-described as “The fun lover’s online casino,” between a robust sportsbook, hundreds of games in the casino, and a beautiful logo (that reminded us of Pringles!), Mr Play Sport may indeed be the most fun gambling site in the UK.
With more banking offerings than most UK gambling operators, the payment method options at this online betting site are varied. Here, you can use debit cards, Neteller, Trustly, Instadebit, and MuchBetter, among many others.
Sports Betting Options - 5/5
Mr Play Sport is one of the top UK betting sites when it comes to market size. This online bookmaker supplies over 30 global sports with dozens of leagues and hundreds of games to bet on within each sport, entertainment and novelty betting, eSports, futsal, and more.
You can often find over 1,400 daily soccer matches, dozens of international amateur and professional golf tours, and basketball fans have 44 leagues to bask in, plus 3x3 basketball.
This betting site is also an amazing platform for all the major American leagues, offering over 350 pre-season betting options for the NFL alone. And with 25+ tracks from around the world, Mr Play Sport is one of the best horse racing betting sites too!
Make sure to check out the Mr Play Sport online magazine, which offers cool articles covering sports news, expert predictions, and sports betting strategies, among other useful topics.
Casino Games - 4.3/5
Unlike most casino sites that provide 500+ games, you will not find a great selection of table games at this online casino.
But Mr Play does not disappoint when it comes to slots and live dealer games. You have over 400 slots to spin, from classic three-reel to dynamic video slots, including over 300 mainstream or branded titles, like Starburst XXXTreme, Narcos, Fruit Shop, and Downton Abbey.
For live games, you have over 120 tables to choose from for blackjack, baccarat, roulette, game shows, and other card games.
Welcome Bonus - 4.3/5
Mr Play Sport gives new players £10 in free bets with no playthrough requirements. To get your £10 bet credit, simply place a £10 bet at minimum odds of 2.00.
While this is not as large of an offer as the sports deposit bonus at FansBet, since there are no rollover requirements, it is still a great chance to take home some bonus winnings.
Mobile Compatibility - 4.7/5
For the most part, the mobile experience is a good one at this betting site, but there is certainly room for improvement.
The usability of the mobile site functions flawlessly for the most part but feels like a PC site rather than a mobile one with an app-like design. This leads to more scrolling and button pushing than what’s desirable, though that is a minor flaw in the grand scheme of things.
5. Leo Vegas - Best UK Gambling Site for Live Dealer Games
T&Cs apply. New reg only. Claim by placing a min deposit of £10 via the "My Offers" page within 30 days. Skrill/Neteller deposits excl. 7 days to stake max £10 in-play. Max. extra winnings £100. Note that the full T&Cs apply.
- Multiple welcome offers to choose from
- £100 welcome package
- 1,500+ casino games, 170+ live games
- Over 1,200 slots (50+ Megaways)
- Great mobile app
- Dated desktop design
- Few table games
Debuting on the online gambling scene in 2012, players love LeoVegas Sport for its excellent sports markets, high-quality slots, and live games.
Sports Betting Options - 4.5/5
The overall design of LeoVegas feels like a website from years gone by. Navigating around the sportsbook is easy, and it usually has great response times. It just lacks a modern look and isn’t that fun to use.
But those flaws do not impact the competitive odds and over two dozen sports the bookmaker offers.
This is an excellent platform to bet on all the primary leagues, which is what most players are looking for, but you won’t find the robust options that FansBet or Mr Play Sport offer. For example, there are usually just two leagues offered for baseball (MLB and Mexican League).
But LeoVegas Sport does offer deep markets for esports and novelties.
Some unique offerings to bet on include professional wrestling, politics, television and movie award shows, and casting calls, and this may be the only UK sportsbook to offer the world’s fastest ball sport, jai alai.
Casino Games - 4.5/5
Impressively, the vast majority of the 1,200+ slots at LeoVegas are popular or branded titles, including an outstanding collection of over 50 Megaways slots.
Oddly, LeoVegas mixes in live dealer games with its few casino table game options. The thumbnails don’t always indicate if a title is a live game, so they once again have players clicking away needlessly.
But when it comes to its live casino, LeoVegas is one of the best options. The games are well-organised and are of great variety, consisting of roulette, baccarat, poker, online blackjack, and game shows.
Welcome Bonus - 5/5
Upon signing up, you can either claim a sports betting bonus or a casino bonus at LeoVegas.
If you’re a sports bettor, you can get a 100% profit boost up to £100 on your first live wager — but it has to be via mobile. The maximum stake you can place is £10, and your payout will be doubled up to a maximum of £100.
New reg only. Claim by placing a min deposit of £10 via the "My Offers" page within 30 days. Skrill/Neteller deposits excl. 7 days to stake max £10 in-play. Max. extra winnings £100.
If you’re a casino player, you can claim up to 50 bonus spins and a welcome bonus of up to £100 on your first two deposits at LeoVegas.
Deposit at least £10 to get 25 bonus spins on Starburst with no playthrough requirements. This magnificent offer is good on your first two deposits.
The deposit match also applies to your first two deposits for a total bonus up to £100. A minimum deposit of £10 is required, and the rollover is 35x.
Rather than matching your deposit by one specific percentage, LeoVegas Sport is giving you some options for your reward:
- Depositing £10 - £24 = £10 reward
- Depositing £24 - £49 = £25 reward
- Depositing £50 or more = £50 reward
New reg only. Opt-in & deposit £10, £25 or £50 within 7 days & further 7 days to wager cash stakes 35x to unlock the reward (£50 on 2 deposits). 3-day exp. Wagering/game contributions vary. 25 wager-free spins x10p to added to Big Bass Splash with each qualifying deposit, 3-day expiry.
Mobile Compatibility - 4.7/5
Just a few years ago, LeoVegas Sport actually garnered an award for its app, and we agree that mobile bettors will love this gambling site.
The mobile browser experience is much better than the PC version, offering fast and intuitive navigation.
Rating Methodology for the 5 Best UK Gambling Sites
Sports Betting Options:
We analysed the odds, number of sports offered, and other betting markets, like horse racing and novelty betting. In addition, we considered the number of markets under each sport provided.
More than just analysing the number of games offered, we studied the variety and quality of games. After all, a casino can offer 150+ table games, but if they lack variety, then the number of games is irrelevant.
A bonus offer is only as good as the playthrough requirements attached to it, so we first looked at the rollover of each bonus. Next, we considered the size of the bonus and any additional perks the offers may contain, like bonus spins or wager-free sports bets.
Offering a mobile app is great — which did garner some casino sites some points — but most importantly, we analysed the mobile in-browser online betting sites for usability, design, speed, and responsiveness.
Quick Guide to Online Gambling in the UK
Is Gambling Online for Real Money at UK Gambling Sites Safe?
Yes, but only if you are gambling at licensed and reputable online casinos and online betting sites in the United Kingdom. Licensed UK gambling sites — like Kwiff and PlayOJO, which are licensed by the UK Gambling Commission — are audited to make sure they are implementing top security measures to ensure safe transactions.
Are Online Gambling Games in the UK Fair?
The online casino games at licensed UK gambling sites are fair and safe to play. Licensed and regulated online gambling sites only use software providers who supply RNG (random number generator) games, guaranteeing random game results.
Who Sets the Odds at UK Online Gambling Sites?
Online bookmakers use expert oddsmakers to set the lines. There is almost always a heads oddsmaker for each major sport offered. The head oddsmaker is always a genius or advanced mathematician with expert knowledge in the sport they cover.
Should I Claim Bonuses at United Kingdom Gambling Sites?
A deposit bonus or extra spins at UK online gambling sites are worth taking advantage of if the rollover requirements are fair and attainable. With that in mind, we only included casinos and betting sites that provide fair terms and conditions.
One prime example is PlayOJO’s 50 no-wager bonus spins that you can claim when you deposit £10.
How Do I Know Which of the UK Gambling Sites is Best for Me?
