Bonus Terms

To be eligible for the welcome promotion, you must deposit at least £10. Your deposit defines the bonus amount. For instance, you will receive a £25 bonus if your deposit is between £25 and £49. The second deposit offer is subject to the same rules.

Before you receive the bonus money, you must wager your deposit 35 times. You will also get 10 Big Bass Splash spins, equally distributed between your two deposits. The value of each spin is £0.10.

Before withdrawal, you do not have to wager the spins generated value. The promotion is available for seven days.

Pros & Cons


  • The selected slot game has a payout rate of over 96%.
  • Gamblers do not have to roll over their generated value from spins.


  • Depositing £24 or less and £49 or less will give your a £10 or a £25 bonus.

What to know about cashback

Gambling will eventually entail some dose of losses. However, these sums do not always go in vain. Players may be able to recuperate parts of what they lost over the past sessions using some of the options we have curated for them.

Best cashback casinos with bonuses

Here is a list of tips you should know about these casino promotions:

  1. Rookies often wonder if hey can withdraw casino bonuses. The answer is yes! Finish the required turnover to cash out your profits.
  2. No matter how much the profit sum rises in a player account, the actual withdrawal sum is limited by the maximum cash out posted in the terms.
  3. Cashback bonuses are by nature tied to the losses amounts of the past gambling history. We do not advise non-experienced players to count heavily on losses to recuperate. Gamble safely!

Exclusive no deposit casino bonuses

Occasionally, casinos supply the public with exclusive bonuses that British players can claim if they register through a special link or with a bonus code.

That’s the case with several entries in our sign up bonus lists, for instance NetBet’s 20 free spins on Starburst.

Finding low wagering offers

Our experts focus on selecting bonuses with an easy wagering, lower than 20x, but the best casino bonuses may sometimes have higher requirements. To help you choose the best for you, we’ve organized our lowest wagering casino offers on a separate page.

How to Find the Best Casino Sign Up Bonus

  1. If you want to play slots, you should prioritise a no wagering casino bonus with a lower value over a high-valued offer with an equally high playthrough.
  2. Compare the deposit bonuses available to find the offer that gives you the most benefits for the same payment. Make your first deposit strategically.
  3. Choose casinos with permissive bonus bet limits – at most casinos, the maximum eligible bet is the lowest between £5 or 10% of the initial bonus amount.
  4. You should also keep an eye out for the conversion limit and choose offers with no limit on winnings. This type of unlimited conversion bonus is most common at live dealer casino sites.
  5. Mind the time limits and ask yourself if you have enough time to complete your casino welcome bonus wagering requirements.
  6. Choose a payment method that is suitable for fast cashout. Use our same day withdrawal casino list as a reference point.

Remember to carefully weigh each detail of your casino sign up bonus before you make a payment.

How to find the best casino sign up bonus

Finding new casinos bonuses for your taste

Every time we add a new UK casino to our database, we claim its latest bonuses and test them systematically. We pinpoint what a new player’s experience will be like in our casino reviews and focus on player safety indicators, as well as the available gaming options.

For this listing, we recommend trustworthy gambling platforms launched from 2021 onwards that provide top online casino sign up bonuses. Our UK-licensed partners provide all the security features you need to play safely, plus hundreds of new games to try.

Our advice: pick the lowest wagering casino bonuses!

When looking for low wager offers, your research process should direct you toward any promotion with playthrough lower than 40x. Of course, a wager-free 50 free spins offer can be considered a low wagering casino bonus.

How to Sign-Up at Legit Casino Bonus Sites

  1. Suppose you study one of our latest casino bonuses and decide it’s worth your time and money.
  2. You may decide to follow our link and claim the bonus.
  3. Make sure you only use your own – not another’s – personal information for registration.
  4. Complete the sign-up process with the correct contact information. Otherwise, you may not receive your casino sign up bonus link.
  5. Complete the KYC checks early by adding a valid debit card as you complete the process.

Only create casino accounts in your name

Using another person’s data to claim a sign up bonus is a form of identity theft. Pretending to be something you’re not is technically illegal and explicitly frowned upon in any casino Bonus Policy.

Use accurate contact information as you complete the registration process

Double-check to enter the correct phone number and email address when you create a new player account. Some of our best casino bonuses can only be activated through a special link you receive in your inbox.

Get the KYC done instantly by adding a card

If you’re a debit card user, you can start the verification process automatically right after you’re done with the sign up form. Add a valid card and your personal and income information will be shared with the casino.

Moreover, many UK online casinos will give you free spins on card registration, so make sure you don’t miss out on this type of KYC verification. Doing so will enable you to cash out your best deposit casino bonuses faster and bypass the usual delays unverified players may face.

Prevent being labelled a bonus seeker

Here is our list of tips that will help you maintain your eligibility for UK casino bonuses:

  • Do not create multiple accounts to claim a casino sign-up bonus more than once – not with fake information or your friends’ data.
  • Make sure you don’t cross the maximum allowed bet – that’s a sure recipe for bonus cancellation.
  • Another form of bonus abuse is suspending gameplay when you activate a slot’s special feature (for instance, the scatter books in Book of Dead). The abuse occurs, after clearing out the wagering requirement, you restart the game and collect the special feature’s payout with real money instead of bonus funds.
  • Avoid safe bets in roulette when you play with a bonus – several online casino bonuses forbid betting on even-money propositions (like Red/Black).
  • Do not attempt to claim the best casino bonuses UK casinos have to offer if you’re not a UK resident. Look up the restricted countries in the casino’s Terms to be sure.

Remember to Play Responsibly

Play Responsibly to Get the Most of Your Casino Bonus

Keeping a cool head and gambling within a realistic mindset is vital. We’re here to remind you how to use the best casino bonuses UK to benefit fully: play responsibly!

Can bonus incentives enable gambling addiction?

A small percentage of UK players are at risk of developing addictive tendencies when playing with online casino offers. It can lead them to abusive bonus seeking, and the volatile nature of gambling itself can enable patterns of chasing losses.

Still, if you trust KingCasinoBonus experts and follow our responsible gambling guidelines, the risk is highly diminished because we tell you exactly what precautions to take.

Use responsible limits

Even when playing with no deposit casino bonuses on registration, you should configure the responsible gambling limits available to plan your gambling activity.

Suppose you claim one of the best casino bonuses listed on this page. In that case, chances are you’ll follow up with a deposit and become a regular player. So, it’s better to play it safe right from the start.

Take the time to define your suitable gambling limits

  • Deposit limits: how much you can deposit in a certain time frame.
  • Wagering limits: how much you can play within a certain period.
  • Session limits: logs you out automatically after a preset time has elapsed.
  • Take a break: temporarily close your account.
  • Reminders: on-site notifications when you cross certain time/money thresholds.

Apply bankroll management

What sets apart amateur punters from professional gamblers is their approach to bankroll management.

It would help if you outlined your money management strategy before you start playing with a casino bonus. That may help you convert your casino bonuses easier and avoid falling into toxic betting patterns. We have some of the best casino game guides to aid new players’ first steps.

Recommended casino bonus bankroll strategy

  1. Start by defining your gambling budget for a month.
  2. Divide your bankroll in multiple equal parts – one for each casino game you like to play.
  3. Claim high-value deposit match bonuses like the 200% deposit bonus so you increase your bankroll on the spot.
  4. Set your base betting unit. We recommend betting up to 2.5% of your bankroll at a time.
  5. You need to constantly adjust your unit to reflect the up-to-date reality of your bankroll.

The only situation in which it is advisable to increase your betting unit is after a significant win. Yet, if you apply progression systems like the James Bond roulette strategy, you must go precisely the other way!

Seek professional help early if you…

  • Feel you commit too much time and financial resources to online gambling.
  • Can’t resist the urge to play online, even at the oddest of hours.
  • Neglect your friends, family and work obligations to gamble.
  • Believe you’ll eventually break even or recoup prior losses.
  • Expect or even trust that a life-changing jackpot is coming your way.
  • Experience remorse after or during betting.

These bullet points alone do not mean you’re a fully-fledged addict, but they’re reliable gambling addiction indicators. Our best advice is to seek counselling or psychotherapy if you can relate to them.

Casino Bonus FAQ List

What is a casino bonus?

A casino bonus is an incentive or coupon that online gambling platforms give for creating new player accounts.

The phrase ‘casino bonus’ usually refers to the new player casino welcome bonus. However, existing players can also claim casino bonuses based on their activity and the operator’s promotional scheme.

Can you really cash out your casino bonuses?

Yes, cashing out casino bonuses is possible if you meet the casino’s wagering requirements. These refer to:

  • how many times you need to play your bonus or deposit funds;
  • the maximum bet you’re allowed to place with your bonus or free spins winnings;
  • the maximum amount you may convert to cash from your casino bonus.

Casino bonuses should not be mistaken for free funds! Wagering conditions are in place to clarify that bonuses are intended not as a way to get free money but as a free trial of the platform – which may or not result in a cashout.

How does bonus wagering work?

  1. Suppose you claim a 100% match casino welcome bonus with a 40x wagering requirement.
  2. You decide to deposit £20 and activate an equivalent £20 bonus.
  3. To cash out the deposit bonus, you need to wager 40x £20= £800.
  4. Check whether wagering is calculated per bonus funds-only, real money-only or bonus and deposit combined.
  5. If our example were a casino sign-up bonus with wagering on bonus and deposit combined, the calculus would have been: 40x (£20+£20)= £1600.

Are UK casino welcome bonuses worth it?

Yes, but not all casino welcome bonuses are created equal. Each bonus package has different conditions that make it more or less appealing. In our view, what makes welcome bonuses worth it is that you can prolong your gaming sessions.

We’ve come to know what the best casino bonuses look like and the UK players’ expectations. Thus, you can trust us to put forward the best casino bonuses for each type.

Can a casino cancel your bonus?

If you breach the casino’s bonus abuse rules, it is entitled to legally cancel your bonus without further explanation.

Remember! Casino bonuses’ Terms and Conditions are like a contract between you and the platform. Once you agree with them and create your account, your actions may only unfold within the stated limits.

Can you bonus hunt without breaching T&Cs?

Yes. Following the latest casino bonuses is fair, but it may lead to ugly situations. Keep aware of UK casinos’ most common bonus abuse rules. Apply our tips and stay on the safe side.

Otherwise, you risk being labelled a bonus seeker and have your online casino offers removed from your account.

Where to find high roller casino bonuses?


How do I claim the best casino bonuses?

Easier than you imagine. Enter the online platform that has this kind of offers, create an account and make the qualifying deposit. In some cases, it would be necessary to insert a code but that depends from one website to the other. As soon as you completed these steps, the bonus will be added automatically to your account.

Can I withdraw a bonus as real cash?

The bonus you obtained as a part of an offer is not withdrawable. The winnings that come from that offer can be cashed out but only after the player has fulfilled the wagering requirements.

How many times can I benefit from casino offers?

This varies according to the online platform you are gambling at and the type of offer you opt for. A welcome/first deposit bonus can be claimed only once. Offers credited for existing and all players can be claimed more than once, as it is in the case of match deals or bonus spins. Make sure you visit the T&C to discover all the details.
