Casino bonuses are the best way to discover new sites and play real money games online. On this page, you find all the best online casino bonuses for UK players with easy-to-understand details about what makes them special.
Before we get to the list and we look at what are the different UK casino bonuses to claim, let's look at the most important elements to consider when choosing a casino offer.
- All casino sites apply different terms and conditions to the casino bonuses they offers. Depending on factors like the wagering requirements, the cap on winnings, and games included in the offer, some bonuses can be better than others — even when they offer the same amount of free money or free spins.
- The games included in the promotion impact the bonuses, massively. Depending on what you can use the casino bonus for, an offer can be best for slots players or for table games players. Given only a few casino bonuses let you play live dealer games for free, you need to read the fine print if that's what you want to do.
- Payout times and support matter, too. There's no point in using a casino bonus to play real money games if you can't cash out your winnings. The best offers are the casino bonuses that let you keep what you win.
- [B]All the offers on this page come from websites licensed by the [I]united Kingdom Gaming Commission[/I] (UKGC). We believe in fair and safe gambling, and playing on legal UK casino sites is the only way to make this happen.
On this new CasinoSmash guide you'll learn how to recognise the different bonus types on offer at online casinos in the United Kingdom, how to read the terms and conditions, and what are the top casino offers based one the games you like to play.
A Note about Responsible Gambling
Gambling games can be addictive and they are potentially destructive for those who play for the wrong reasons. If you think claiming a casino bonus is a good way to get away from the stress of your daily life, think again.
Playing for financial gains is also not a good idea. The house edge is never in your favour and despite the casino offers you find online or the strategy tips you apply to your games, the odds will never be in your favour.
Here at CasinoSmash we believe in fair and responsible gaming. Since we like to put our money where our mouth is, we even co-founded RAiG, an association that brings together affiliate sites like ours and sets best practices to promote gambling in an appropriate and never misleading way.
That's why we are here to tell you that you should always gamble responsibly, even when you use a casino bonus to play for free.
Caring about the money you spend on the games and being financially responsible about it is the only way to go to keep gambling fun and enjoy all the casino offers on this page.
Bookmarking pages like GamCare and the BeGambleAware website is an excellent +EV move for you. Keeping these websites handy will help you keep your gambling habits under control and get the help you deserve, whenever you need it.
Top Casino Bonuses in the UK: The Full List

What Are the Best UK Casino Bonuses?
A good casino bonus is an easy and inexpensive way to play games online and discover what casino websites have to offer.
We spent over a month on research, spoke with marketing managers at more gaming websites than those you see in the list, and tested all these offers to see how they really work.
This allowed us to identify what we believe to be the best casino bonus you can claim right now: the PartyCasino new player bonus.
It offers the best combination of free spins on Starburst, a lower-than-average wagering requirement, and access to even more promotions after that.
Best Casino Bonus for UK Players: PartyCasino
50 Free Spins on Starburst
PartyCasino is our go-to casino site for slots players. Why? Because they combine a great selection of games with a generous welcome offer to enjoy 50 free games on Starburst.
- 25 free spins to play Starburst
- 10x wagering requirement
- Impressive selection of games
- Use the 'Free Spins Prize Wheel' for more bonuses
18+. New depositors only. UK residents only. Minimum deposit £10. Free Spins are valid only on Starburst and expire in 7 days. 10x wagering apply. Certain deposit types are excluded. T&Cs apply.
PartyCasino is one of the top gaming brands in the world and one of the most popular online casino sites in the United Kingdom.
The welcome bonus is easy to claim and has simple terms and conditions attached to it. Considering how popular the Starburst slot machine game is in the UK, we believe this offer will make a lot of you very happy.
When you register on PartyCasino, you receive 50 free spins on Starburst as soon as you deposit £10 or more. To use the bonus you need to activate the free spins via the 'My Free Spins' section of your account within 7 days.
Each free game is worth £0.10 and there is no cap on winnings, meaning what you can turn the 50 free spins welcome bonus into is an affair between you, the Starburst game, and Lady Luck.
PartyCasino applies a 10x wagering requirement to the winnings generated through the welcome bonus. This is one of the lowest you find in the UK casino industry today and it gives you great chances to keep what you win.
The only flaw of this bonus concerns the payment methods included in the promotion. Make sure you do not use PayPal, PaysafeCard, LuxonPay, Skrill1Tap, Neteller, Instandbank (Trustly), Apple Pay, PCard, MuchBetter, or a credit card as these payment methods are not eligible for the promotion.
What's special about PartyCasino is that this is only one of the many offers on tap. If you are interested in even more free spins, make sure you don't miss the site's 'Free Spins Wheel' promotion.
Best No Deposit Bonus Offer: 888Casino
£88 FREEPLAY No Deposit Bonus
888Casino offers one of the most generous welcome bonuses in the UK, with £88 in FREEPLAY available to all new players who register on the website.
- Free £88 no deposit bonus
- 50x wagering requirement
- Lots of exclusive and jackpot games
- No promo code needed
New players only • Claim within 48 hrs • 14 day expiry • FreePlay (FP) wins credited as bonus & capped at £10, excl. JP wins • Valid for selected games • Bonus wins capped at £500, excl. JP wins • Pre-1st deposit only: Bonus wins & max redeemable amount capped at £100, excl. JP wins • 50x wagering – req. vary by game • Bonus expires in 90 days • Withdrawal restrictions, T&Cs apply.
Although you might not get the chance to use your bonus on a classic slot like Starburst, the 888Casino bonus is another offer we believe is going to surprise a lot of UK casino players.
Open to players in the United Kingdom and Ireland, this casino bonus is the most generous no deposit offer on the market - even despite the £500 cap on winnings included in the offer's terms and conditions.
Register a free gaming account via this page on 888Casino to receive their spectacular £88 FREEPLAY bonus with no deposit needed.
The bonus is valid on selected games and the wins, as mentioned, are capped at £500. The reason we rank this bonus lower than the PartyCasino one is the 50x wagering requirement applied by 888.
With 90 days to clear the bonus, it might be a bit difficult for most players to clear the playthrough requirement and request a withdrawal.
A deposit of £20 or more triggers the second welcome offer at 888Casino, with the site doubling the amount of your deposit for up to £100 in bonus money. The wagering requirement applied to this bonus is 30x.
Best Casino Bonus for Slots Players: Casino.com
200 Free Spins and up to £100 on Deposit
Casino.com is an industry-leader gaming platform with a top choice of slots, table games, and possibly the best live casino platform in the UK. Their deposit promo is a value packed-offer that combines bonus cash and free spins.
- 200 free spins on Age of the Gods games
- Up to £100 in bonus money for all other games
- 20x wagering on free spins, 40x on bonus funds
New customers. Min deposit £20. 40 free spins on first deposit. 160 free spins after first deposit (20 per day). Max win £100. 20x wagering. Deposit bonus 40x wagering. Expires 30 days from issue. Eligibility, game, platform, payment restrictions, and T&Cs apply.
The best bonus to play slot machine games online is the one at Casino.com and is available to all players in the United Kingdom and Ireland.
Everything happens right after your first deposit, with the site giving you 40 free spins and a 100 percent deposit match for up to £100 in free bonus money as soon as you deposit £20 or more.
You will receive also an additional 20 free spins per day for the next eight consecutive days for the impressive total of 200 free spins!
While we understand that a £20 deposit isn't cheap, we find this to be a value-packed offer as the minimum deposit gets you an additional £20 in bonus money and 200 free spins on selected games.
The casino bonus is valid to all the players who register a new account on the website. To claim this offer, you must be 18 or older.
What makes this a great casino bonus for slots players is also the fact that the free spins come with a 20x wagering requirement (the multiplier raises to 40x for the bonus money).
There's a thirty-day expiry time connected to this deposit bonus offer - so you'll need to be relatively quick once you get it.
Other Recommended Sign Up Bonus Offers
The three online casino bonus offers above are not the only options to play casino games for free, especially if you don't mind the idea of making a deposit.
On most online casinos, your initial deposit is matched with a bonus - and while the minimum deposit may vary between £5 and £10 depending on the gaming sites, the offers that follow are some of the best deposit and no deposit bonuses UK players can claim this year.
LeoVegas Casino Bonus
Did you know the Book of Dead game is the second most-played slot machine after Starburst? The welcome bonus at LeoVegas is the perfect offer to enjoy this super-popular game and join Rich Wilde in his treasure hunt.
You get 10 free spins with no deposit needed as soon as you complete the registration process on the website. The free spins are wager-free meaning you also get to keep what you win.
Bear in mind we are talking about 10 no deposit free spins worth .10p each, so you shouldn't see this bonus as a chance to become a millionaire but rather a way to play free games on one of the top slot machines out there.
It's also a way to get your foot in the door at LeoVegas and get your place in line for their first deposit bonus offer. Deposit £10, £25 or £50 within seven days from creating your account and the site will give you up to £100 in bonus money (play through requirement: 35x) and 20 additional free spins, again with no wagering requirements.
777 Casino Bonus
[room:/reviews/777-casino][/room]
Coming from the same family as 888Casino, 777Casino is also a reliable, safe, and generous website with lots to offer to new players.
Right now, their welcome promo includes a two-part offer that combines a no deposit and a post-deposit bonus.
Register via CasinoSmash to receive 77 no deposit free spins on Ray of Light, Lucky Orbs, Noche de los Muertos, and Millionaire Genie. The free spins need to be claimed within 48 hours, expire in 14 days, and lead to wins credited as bonuses that are capped at £10.
If you go for a deposit, the casino promo code WELCOME777 is your best shot at extra bonus money. This bonus code triggers a 100% match offer that gives you up to £200 instant FREEPLAY.
The terms and conditions of the deposit bonus include a cap on winnings set at £500 and a wagering requirement of 30x.
BetVictor Casino Deposit Bonus
It depends on the casino bonus. While some can be redeemed on any game that you like, others may only be applicable to select slots or a specific game range. Check the T&Cs of any offer before redeeming.
