#1 Casushi Casino: Best Casino Bonus Overall 2023

Current Bonus: 100% bonus up to £50 + 50 spins on Book of Dead

Overview: Casushi Casino comes out on top after considering everything that goes into new customer offers at the best casino bonus sites. The promotion might look good on the surface, but you also need to look for favourable terms such as wagering requirements, minimum deposit and max win limits. This operator shines in these areas.

🥇Best Features of the Casino Bonus

• Minimum deposit is low (£10)
• Wagering is fair (40x)
• Max win limit is higher than many other casino bonuses (£250)
• 100% up to £50
• 50 bonus spins on Book of Dead

😬 Any negatives? While this casino bonus is good, nothing’s ever perfect. It would have been great to see a longer expiry date on the free spins, which is set to just 48 hours. 72 hours or even 7 days would have been ideal, so just make sure you use the free spins within the timeframe specified.

It’s also important to consider the casino overall in terms of withdrawal speed, slot availability and payment options.

Reasons to choose Casushi Casino

• 1,000+ slots
• Under 24-Hour Withdrawals
• Numerous payment methods including PayPal
• Search for slots by provider
• 70+ progressive jackpot slots
• Uniquely-themed website
• Good loyalty program

🧑🏻‍⚖️ Our verdict: A top UK casino bonus with fair terms and a top operator overall with numerous payment options and fast withdrawals. You don’t always see casinos offering loyalty programs, so it’s great to see you can convert points into bonus spins at Casushi.

#2 Playzee: Best First Deposit Bonus

Current Bonus: 100% bonus up to £300 + 150 spins on Starburst

Overview: After analysing many of the best casino offers for UK players, Playzee came out on top for us in terms of being the best first deposit bonus. The 35x wagering is very fair and attainable, and there are 3 parts to the offer, which is great to see as there are a lot around offering only bonus money or free spins.

🥇 Best Features of the Casino Bonus

• Fair wagering (35x)
• 100% up to £300
• 150 spins on Starburst
• You get 500 loyalty points
• No payment method restrictions

😬 Any negatives? The minimum deposit for this promotion is £20. Some other UK casino bonus offers have a minimum deposit of £10 set, so it would have been great to see this at that level. Additionally, the free spins are spread over numerous days rather than being awarded in one go.

🧑🏻‍⚖️ Our verdict: There aren’t many casino bonuses that have 3 separate awards. At Playzee you get to enjoy a matched deposit bonus, free spins, and loyalty points. The fact there is a loyalty program at Playzee is also great to see. Furthermore, as a casino itself, it’s superb with over 3,700 slots available to players.

Pub Casino – 100% up to £100

#3 LeoVegas: Top No Wager Bonus

Current Bonus: 100% bonus up to £100 + 50 no wager spins on Big Bass Splash

Overview: LeoVegas is one of the world’s most well-known brands and they always have some fantastic no-wagering promotions, with their latest one being no different. Ok, so the first part is a deposit bonus, but you’ll also get up to 50 free spins on Big Bass Splash that do not have any wagering requirements, which is the highest amount on offer across all UK casinos at the moment on our site.

🥇 Best Features of the Casino Bonus

• Up to 50 free spins on a popular slot (Big Bass Splash)
• No wagering whatsoever
• Deposit bonus included in the offer
• Withdrawal of any winnings within 24 hours

😬 Any negatives? The no-wager spins come with a 3-day expiry. It would have been good to see this increased to 7 days, but 3 days isn’t too bad compared to a lot of other bonuses. The other part of this LeoVegas promotion includes a 100% bonus of up to £100. While this looks good, the wagering is 50x, which is quite high compared to the competition.

🧑🏻‍⚖️ Our verdict: There aren’t many casinos around that offer wager-free spins, so this puts LeoVegas above the majority of casinos in that sense. Furthermore, the operator itself is one of the most respected in the industry.

🎰Alternatives

Jackpot Casino – 50 no wager free spins on Bigger Bass Bonanza

#4 Party Casino: Best Exclusive Casino Bonus

Current Bonus: 120 free spins on Starburst

Overview: We regularly get exclusive UK casino bonuses from operators and the best we have at the moment is from Party Casino. You can enjoy 120 free spins on a popular slot with low wagering and a reasonable expiry date.

🥇 Best Features of the Casino Bonus

• 120 free spins on Starburst
• Low minimum deposit (£10)
• Low wagering (10x)
• Reasonable expiry date (7 days)

😬 Any negatives? While there are numerous payment options available, you can only use debit cards, Apple Pay or PayPal to claim this offer. This is plenty in our opinion, but it’s always ideal to see no restrictions at all.

🧑🏻‍⚖️ Our verdict: The wagering on the free spins is one of the lowest in the industry, which is a huge positive. Not only are you getting a superb UK casino bonus, but you’re also signing up at a fantastic casino with 3,800+ slots to choose from with over 165 being exclusive. Not many operators can boast this.

🎰 Alternatives

#5 MrQ: Top Mobile Casino Bonus

Current Bonus: 30 no wager spinsBig Bass Splash

Overview: If you enjoy playing on your smartphone, you’ll be pleased to know that you can claim many of the best casino bonus offers in the UK. Our pick right now is MrQ’s 30 no-wager spins on Big Bass Splash. You’ll have to deposit £10 to get the free spins, but the fact there is no wagering attached is something very few casinos can boast.

🥇 Best Features of the Casino Bonus

• Low minimum deposit (£10)
• 30 free spins on the popular Big Bass Splash slot
• No wagering requirements whatsoever
• No Payment method restrictions

😬 Any negatives? You must use the free spins within 48 hours. It would have been great to see this extended to 72 hours or even 7 days.

🧑🏻‍⚖️ Our verdict: MrQ is a superb choice for mobile and desktop players alike. The bonus is a good one and the casino itself offers slots with the highest RTP rates available and e-wallet withdrawals are fast.

🎰 Alternatives

Electric Spins – 200% up to £20 + 100 free spins

#6 PlayOJO: Best Free Spins Bonus

Current Bonus: 80 no-wager free spins on Book of Dead

Overview: Casino’s new customer offers don’t come much more generous than the one currently available at PlayOJO. You’ll have to deposit £10 to claim it, but you’ll get 80 free spins on Book of Dead with no wagering requirements attached at all. Not only that but the casino itself has 3,000+ slots available as well as withdrawals within 24 hours. It’s a great place for players to play.

🥇 Best Features of the Casino Bonus

• Low minimum deposit (£10)
• Free spins on a popular slot (Book of Dead)
• No wagering requirements whatsoever
• No payment method restrictions
• 30-day expiry

😬 Any negatives? The free spins won’t all arrive together. You get 50 initially and then you have to claim the other 30 yourself in the Kicker section of your account within 3 days.

🧑🏻‍⚖️ Our verdict: Book of Dead is one of the most popular slots around, so it’s great it is the game of choice for the casino bonus. You will never see wagering terms attached to any offer at PlayOJO either. Overall, it’s a great place for players to play.

Casushi Casino – 100% up to £50 + 50 bonus spins

#7 Mr Vegas Casino: Top Slots Casino Bonus

Current Bonus: 100% up to £400 + 150 spins on Starburst

Overview: Mr Vegas Casino has been a popular choice since its launch in 2017 and has well over 4,000 slots for players to choose from. The current welcome bonus is fantastic and comes in 2 parts. Not only do you get to enjoy one of the best first deposit bonuses at a UK casino, but you also get 150 free spins on the most-played online slot ever – Starburst.

🥇 Best Features of the Casino Bonus

• Low minimum deposit (£10)
• 150 free spins on a very popular slot (Starburst)
• Low wagering on free spins (25x)
• No payment method restrictions

😬 Any negatives? The way the bonus funds are paid to you is a little odd. Say you’re due £100. You will get 10% instalments until the £100 is paid in bonus funds. Additionally, the expiry date on the free spins is 24 hours. This doesn’t give you long to use them, so make sure you do before they disappear.

🧑🏻‍⚖️ Our verdict: There aren’t many UK casino bonuses that offer such a high matched deposit alongside low wagering requirements, which makes this one stand out from the crowd. The overall experience you’ll enjoy at Mr Vegas is fantastic too.

🎰 Alternatives

Atlantic Spins – 100% up to £400 + 125 free spins

#8 Winomania: Best £10 Deposit Bonus on Sign Up

Current Bonus: 100% up to £100 + 100 spins (25 spins on Cleopatra, Gold Rush, Wild Eagle and Scratch King)

Overview: Winomania might not be an instantly recognisable brand, but it’s safe, secure and trusted. There’s also a brilliant UK casino bonus for new players that comes in 2 parts. Not only that but the wagering terms are fair and the free spins can be enjoyed on 4 different slots.

🥇 Best Features of the Casino Bonus

• Low minimum deposit (£10)
• 100% up to £100 on your first deposit
• Fair wagering (40x)
• 100 free spins
• x4 25 free spins on 4 popular slots (Cleopatra, Gold Rush, Wild Eagle & Scratch King)
• 30-day expiry on the deposit bonus

😬 Any negatives? It would have been good to see a longer expiry date than 24 hours on the free spins. Ensure you enter the promo code WINO100 to claim this offer too. A casino bonus code can sometimes catch players out, so make sure you don’t forget to enter that when prompted.

🧑🏻‍⚖️ Our verdict: The best casino bonus offers will all come with realistic terms and Winomania’s fits nicely into this category. It’s great to see the free spins spread over 4 different slots too.

#9 PokerStars Casino: Top £20 Min Deposit Casino Bonus

Current Bonus: 100% up to £200 + 100 spins

Overview: Not all of the best casino bonuses in the UK require a minimum deposit of £10. A lot tend to raise the minimum to £20, but that doesn’t necessarily make their bonuses any worse. A prime example is PokerStars Casino, which is the winner in this category. You’ll need to enter bonus code FIRST 200, but you can enjoy a 100% matched deposit bonus as well as 100 free spins.

🥇 Best Features of the Casino Bonus

• 100% up to £200
• Your 100 free spins bonus does not require a deposit
• Can be claimed on mobile or desktop
• Withdrawal of any potential winnings can be back in your account within 1 hour

😬 Any negatives? You can only claim this promotion with a debit card deposit, so just bear that in mind if you typically use another method such as PayPal.

🧑🏻‍⚖️ Our verdict: You won’t get many better new customer offers than this with a £20 minimum deposit. Our offer is exclusive to us too – you won’t find this anywhere else. The no deposit free spins are a fantastic part of the bonus, and just make sure you enter FIRST200 on your first deposit to get the 100% up to £200 part of the offer. PokerStars is a highly reputable brand too.

#10 Duelz: Best Casino UK Bonus for Existing Players

Current Bonus: 100% bonus up to £100 + 100 spins on Book of Dead

Overview: Duelz Casino regularly has many casino bonuses for existing players. But what makes them stand out from the crowd is that you can battle other players to win prizes. While the existing customer promotions are fantastic, it’s also worth pointing out the superb welcome offer they currently have of 100% up to £100 plus 100 free spins.

🥇 Best Features of the Casino Bonuses for Existing Players

• 10% weekly cashback every Friday
• Cash slot tournaments every 15 minutes
• Prizes for battling other players and collecting stars and trophies

😬 Any negatives? There aren’t any downsides to any of these existing player promotions, but the casino itself is quite niche. It won’t be to everyone’s taste. There are other casinos that have more slots listed in their portfolios too compared to Duelz.

🧑🏻‍⚖️ Our verdict: You’ll find plenty of promotions as an existing player at many casinos, but you won’t find any as unique as battling other players to win prizes. Couple that with an appealing cashback offer and you have a solid set of promotions. The initial casino bonus for new players is pretty good too!

Types of UK Casino Bonuses

Each casino bonus has its own uniqueness to it – they all come in different shapes and sizes. There are pros and cons to each one too, and it isn’t easy to pick when there are so many available to you. Let’s run you through the different types of casino bonuses so that you can understand them better.

Free Spins

Video slots have been rising in popularity over the years, and so too have free spins bonuses. You’ll come across numerous offers of free spins either on their own or as part of a welcome bonus package, typically alongside a deposit bonus. A lot of the UK casino bonuses tend to have this type of offer on games such as the Starburst slot from NetEnt or Book of Dead by Play’n GO. They are 2 very popular UK video slots.

But casinos also move away from these 2 typical choices to include free spins on other slots such as Blue Wizard or Gonzo’s Quest. It’s a great chance to test some of these slots if you’ve not yet played them, especially if they’re part of a free welcome bonus where no deposit is required.

You’ll find that no wager free spins are increasingly popular. This gives you the chance to keep what you win when you play a popular slot game. The offers tend to be on the slots mentioned above too.

Here’s a casino with a top casino bonus that includes free spins:

No Deposit Bonus

These are pretty rare these days but no deposit bonuses do still exist. The amount offered on these promotions is small, but it’s always a great chance to use this casino bonus to test out a new slot. Furthermore, there are a few that come with no wagering requirements, which is always great to see.

Deposit Bonus

This is arguably the most popular offer on the market. A lot of the best casino welcome bonuses are usually a percentage up to 100% or 200% of your first deposited amount, and some of the leading deposit casino bonuses like this can spread over 2, 3 or even 4 deposits.

There are typically maximum limits attached such as an offer up to £50 or up to £100, but the top casino bonuses come with fair and attainable wagering.

A lot of casino welcome bonuses often include free spins as part of their sign up offer, so make sure you keep your eyes peeled for those. Mango Casino is one prime example, with free spins on the popular Book of Dead added to their 100% deposit bonus.

Reload Bonus

Casino reload bonuses are very similar to your typical new customer offer but they’re usually available to existing players and often have a lower percentage attached to them. It’s simply a way of encouraging players to play more and acts as a reward in a way.

For you, using it is a great way of being able to get comfortable at a particular casino rather than moving on to a new one. You may need a bonus code with these, you may not, but they do tend to have lower wagering requirements than the best casino offer from a new operator, which is a big plus. These kinds of promotions include:

• One time reload bonuses
• Daily reload bonuses
• Weekly reload bonuses
• Monthly reload bonuses

Cashback Bonuses

These aren’t too common nowadays, but there are some UK cashback casinos around that will give you back a percentage of your losses over a certain period of time. This can be over the space of 24 hours, a week or even a whole month.

No Bonus Casino is a prime example of a UK operator that offers this type of promotion.

Mobile Casino Bonuses

As more and more people switch to a mobile-first way of betting and established and new online slot sites improve their mobile betting experience, it’s only natural that you’re going to see mobile casino bonuses around as operators want to encourage you to utilise your mobile for convenience.

Some UK casino bonus sites even go as far as offering an exclusive promotion just for mobile players by not making it available to desktop users. LeoVegas bonuses are a good example of this, as they take a mobile-first approach and often have smartphone and tablet bonuses running. Although not always, these can also have lower wagering requirements attached.

But it’s worth noting that it’s not just the mobile promotions that can be claimed. Many of the best casino bonuses can be claimed on mobile as well as on a desktop rather than one or the other.

What Makes a Good Online Casino Bonus?

With not too much to choose between the best casino bonuses on the market, it’s not always easy to identify which ones are better than others. You need to go deeper and look at the following:

Let’s expand on each of the above points to help you understand exactly what to look out for with new casino bonuses.

Wagering Requirements

Some of the best casino bonuses have no wagering requirements at all, which is great, and there are some out there. But most of them will, and it’s important that you understand them fully because there comes a point where a certain figure is simply unrealistic and very difficult to achieve.

Let’s use an example. You’ve just registered and have claimed a new casino bonus that offered you £100.  Here’s a useful table to show how much you need to wager to meet certain wagering terms listed:

As you can see, the higher it gets, the more unrealistic the overall bonus becomes. A lot of operators will tend to be around the 35x or 40x mark. Anything over that would start to become unattainable, and there are some casino bonus sites out there that offer 60x and above, so that’s why it’s always essential you understand the wagering terms.

Maximum Payouts

Many casino bonuses these days have a maximum limit set on any potential win. Every casino is different, but we’ve seen values anywhere from £25 up to £500. It’s great if you want to find an offer with no limitations, but they are pretty few and far between nowadays.

Minimum Deposits

Most of the best online casino bonuses require a deposit of at least £10 or more. This is the most common value, but we have also seen minimum initial deposit levels set at £20 or £50. With promotions that reward you for a 2nd, 3rd or 4th deposit, you’ll be required to deposit more than once. However, there are sometimes some no deposit bonuses around that won’t require a deposit at all for you to claim the offer.

Deposit Restrictions

It’s important to check the eligibility requirements and make sure you’re happy with the options available to you as some don’t include popular e-wallets like PayPal, Skrill or NETeller. Even casinos with Apple Pay might not allow deposits with the iOS payment method for the initial offer upon registration.

If this is the case, our advice would be to use another payment method for the deposit bonus and then switch to your preferred method after that. You should bear in mind that e-wallet payment methods are normally the quickest to cash out so if this is important to you, you need to play at a fast withdrawal casino in the UK.

Expiry Dates

There will always be a time limit on your casino bonus. Whether it’s 24 hours, 3 days, 7 days or maybe even 30 days, you won’t come across one without an expiry date. Make sure you take note of the timeframe as you will lose any bonus you don’t use in time.

Country Exclusions

We’re just focussing on UK casino bonuses here, but that doesn’t mean there aren’t any country restrictions here because there are. If you live in Northern Ireland, there will be some promotions you simply cannot get. the Isle of Man is often in the same boat, so double-check the offer if you like outside of England just to make sure.

Eligible Games

Wagering contributions vary and must be considered with any casino offer. For example, playing progressive slots when they only contribute 10% to the overall wagering requirements is not the way to go as it will take you 10 times as long as a slot that contributes 100%.

Here’s one example of the wagering contributions you may come across in the Terms and Conditions of some of the latest casino bonuses:

• Slots = 100%
• Blackjack = 25%
• Roulette = 25%
• Baccarat = 10%
• Video Poker = 10%
• All Other Games = 0%

Bonus Codes

Some of the best casino sign up bonuses will come with a bonus code attached. You will need to make sure you enter this when depositing or registering. If you need one but fail to enter it for whatever reason, get onto customer support as they may be able to add it for you on their end.

A casino that often offers a good bonus with a promo code attached is Amber Spins:

Pros & Cons of the Best UK Casino Bonuses

There are advantages and disadvantages to everything, and the top casino bonuses are no different. Here’s a useful table that will help you understand the good and bad points:

How to Claim the Best Casino Offers in the UK

Most casino sign-up offers follow the same pattern in terms of how to claim them. It’s really quick and easy to get one, just follow these simple steps:

It’s as simple as that with the majority of UK casino bonus sites. If you’re in any doubt, the operator should have an easy guide to follow where the promotion is listed on the website.

Casino Bonus Tips & Tricks

Now you know how to claim a signup offer, we’ve got some tips for you so that you can get the most out of your casino bonuses:

1. Invest time in researching the casino to determine if it aligns with your specific requirements.
2. Evaluate the available promotions for both new and existing players, ensuring you fully understand the terms and conditions.
3. Choose games that contribute 100% towards meeting the wagering requirements.
4. Opt for games with a higher return to player (RTP) rate to maximise your potential returns.
5. Sign up for email or SMS notifications to receive exclusive bonuses and updates on new promotions.
6. Activate push notifications on your mobile device to stay informed about any new promotional offers.
7. Contact customer support to ask about upcoming promotions that may be of interest.
8. After claiming the welcome offer, stay vigilant for ongoing promotions specifically designed for loyal players, as casinos often reward existing customers with additional bonuses.

The Best Games to Play with Casino Bonuses

There are many slots on the market where you can utilise a deposit bonus or free spins. Some promotions will have a set slot attached to the promotion such as Book of Dead or Starburst, but there are many others that allow you to play a range of titles.

As we’re a dedicated slot site, here’s a helpful breakdown of the top UK titles that you can play with some of the best slot promotions:

• Starburst (NetEnt) – The most played online slot ever has been part of the best UK casino bonus offers over the years, and they’re still the slot of choice for many top free spins offers. It’s really simple to understand as you won’t find your fancy bonus features here, you just spin away and hope to land wild reels and fill them with the high-value Bar symbol.
• Book of Dead (Play’n GO) – This slot has been attached to new player casino bonuses for many years, and UK players still love playing the game to this very day. It’s one of the best slots from Play’n GO’s whole catalogue.
• San Quentin (Nolimit City) – This highly volatile game has gone on to become one of the most popular slots on the market. With a max win of 150,000 x your stake and multipliers up to 512x, we can see why. OK, so there are many online casino bonuses that limit the amount you can win, but if you find one with a more generous limit, this slot is a great choice.
• Jammin’ Jars (Push Gaming) –  It’s still one of the slots of choice when using online slots offers. This is not only down to the fantastic visuals and overall gameplay but also due to an RTP of 96.83% and a max win of 20,000 x your stake.
• Immortal Romance (Microgaming) – This game boasts one of the best soundtracks and storylines ever complied. Sarah, Amber, Troy, and Michael go on an epic journey in this 5 reel classic that is a popular go-to for those who use UK slots bonus offers where all games are playable.
• Bonanza Megaways (Big Time Gaming) – The Megaways game engine is always a popular choice for those looking for potentially big returns on their slots casino bonus. Bonanza Megaways has been voted the most popular Megaways slot of them all and comes with unique charm. As a medium to high variance slot, bigger wins will land more frequently than a slot with very high volatility, which works well when using it alongside a slot sign up bonus.
• Gonzo’s Quest (NetEnt) – Around since 2011, it’s still one of the most popular slots to play. Due to the increased multipliers during the free spins feature, the max win potential is a whopping 37,500 x your stake. You won’t hit this with a slot sign up bonus due to the max win limits in place, but 5 symbols in combination can pay well.
• Starburst XXXtreme (NetEnt) – This slot comes with random multipliers up to 450x. Many players still stick to the original game, especially when it comes to UK slots bonuses, but this is also because Starburst is the sole slot attached to many offers. But Starburst XXXtreme takes things to another level and is well worth using as part of a promotion if you get the chance.
• Money Train 4 (Relax Gaming) – Arguably one of the very best ever produced, with full marks across the board in our review. With a solid RTP of 96.1%, it comes with a fun Respin bonus round but it’s really all about the Money Cart Bonus feature. There are 20 special symbols that can really boost your chances of winning big. When there’s an offer allowing wagering on any slot, this is arguably one of the best welcome bonus slots.

Slots Not Included in Casino Bonuses

There are often certain slots that are excluded from any sort of promotion, and they’re the slots with the best RTP and those with extreme payouts. The high RTP exclusions are simply because the returns are so much greater on average than slots that are around the 96% mark, which is the average for an online slot.

For example, Book of 99 from Relax Gaming has an RTP of 99%, so you can understand why casino bonus sites don’t give away any free spins for this one.

On the extreme payout side of things, Nolimit City’s Tombstone RIP immediately springs to mind. You won’t see this slot listed as one you can play with any bonus funds or free spins because the hit frequency is really low at 9.08%.

Titles you won’t see listed as part of the best slots deposit bonus offers include but are not limited to:
