100% casino bonus

A 100% deposit bonus is the most common new player bonus available on UK casino sites. It effectively doubles your initial payment up to a certain amount, enabling you to establish a steady bankroll right from the get-go. Nearly 200 British casino sites offer this type of deal in 2024, and we’re here to help you find the best ones. Check out our list below and read on to learn more about how this particular bonus works.

Understanding a Casino 100% Bonus: What It Is and How It Works

A 100% casino bonus implies that you will get 100% of your deposited amount in the form of bonus credits. For instance, if you were to deposit 50 in your online casino account, you would receive another 50 as a bonus. This means that the more you deposit, the larger your bonus will be, but there’s almost always a limit, usually from 50 to several hundred pounds.

These types of promotions are aimed at new customers to incentivise them to create an account and deposit larger sums of money, but you can also find them as recurring reload bonuses. Also, a 100% welcome bonus may come packaged with another bonus, usually free spins.

It’s essential to read the bonus terms and conditions before claiming this type of offer. There are always minimum deposit limits and wagering requirements that you must meet before attempting to withdraw any potential winnings, while certain bonuses can only become available if you type in a specific bonus code.

Weighing the Pros and Cons of 100 Percent Deposit Bonus Offers

There’s practically no reason not to claim a 100% bonus at a GB casino. Here are some of the main advantages of this promotion:

The welcome bonus 100% offers are generally considered good deals, but all that glitters is not gold. These bonuses can sometimes seem like the casino is giving away free money, which is not the case. There are no true disadvantages to using these bonuses, but they can come with some considerable limitations that can potentially make them not worth your time, such as:

Our Criteria for Rating Online Casinos With 100% First Deposit Bonus Deals

As you can see, our list consists of dozens of ino sites, but some of them are purposefully positioned near the top. These represent the best UK online casinos that feature some of the most valuable 100% bonuses, and here are the criteria we used to come to that conclusion:

Legality and Reputation

All 100% bonus casino deals you can find on this page are offered by secure and legal UKGC-licensed casinos that maintain a solid reputation.

Small Icon 25

Minimum Deposit and Bonus Potential

We give an advantage to casinos featuring bonuses with low minimum deposit threshold and high max bonus amount to accommodate players of all budgets.

Small Icon 19

Wagering Requirements

Since wagering requirements are the biggest hurdle standing between the bonus and your winnings, we pay special attention to this bonus term. The lower the wagering requirements, the better, with 35x to 40x being the industry average.

Small Icon 17

Terms and Conditions

Our evaluation of the bonus is complete only when we look into the full terms and consider other vital factors like game eligibility, wagering contributions, bonus expiry date, payment restrictions, and more.

Small Icon 15

Casino Quality

A good bonus means little unless you use it on a good casino site. We give an advantage to casinos with plentiful game collections, an excellent user experience, a solid range of other promotions, responsive customer service, and optimal banking policies.

100% Casino Bonus Offers in the United Kingdom

100% deposit bonuses

Not every 100% bonus is the same. Some casinos offer them as part of the welcome deal, others combine them with another type of promotion like free spins, while you can also find 100% deposit promotions as recurring offers known as reload bonuses. These promos can differ when it comes to specific rules like minimum deposits, wagering requirements, or game eligibility. It’s also worth noting that 100% bonuses may work differently on online casinos compared to bingo sites or sportsbooks.

That said, let’s take a closer look at all the most common types of 100 percent bonus deals and examine their structures.

100% Welcome Bonus

The 100% welcome bonus is reserved for players new to a casino site. These bonuses mainly differ in their minimum deposit thresholds and max bonus caps.

Deposit £5 Get 100% Bonus

Although rare, there are a handful of £5 minimum deposit casino sites that operate in Great Britain. These are ideal for low-rollers and those who want to dip their toes into the water and see what the casino is all about. If this type of online casino offers a 100% bonus for its newest customers, you can deposit £5 and start playing with £10 right away.

Deposit £10 Get 100% Bonus

£10 is the most common minimum deposit limit on UKGC casino sites. It’s the optimal minimum deposit threshold, enabling a sufficient starting balance without going out of your pocket, especially if you run into a 100% bonus deal. Simply deposit £10 get a bonus, and start playing with £20. You can get this type of deal at Betway Casino.

Deposit £20 Play With £40

In some instances, a casino may require a 20 deposit to give you the welcome bonus. Although 20 pound deposit casino sites are rare, you may come across them on our list. The benefit of these casinos is that they usually offer higher bonuses. For example, depositing 20 or more at Magical Vegas and using the bonus code MAGICAL will reward you with a 100% bonus up to 300 and 50 free spins.

100% Reload Bonuses

Aside from the 100% welcome bonuses intended for new players, many UK casinos offer 100% reload bonuses aimed at existing customers. This bonus can be claimed once you’ve used your welcome bonus funds, and it’s usually smaller than the original bonus. On the flip side, reload bonuses can be used multiple times, usually once every week or month.

Hybrid Bonuses

In some cases, the 100 casino welcome bonus is only a part of a larger welcome bonus package. Aside from the bonus money, you may also receive free spins that you can play on one of the casino’s featured video slots. For instance, the welcome offer on Bzeebet consists of a 100% bonus up to £100 together with 100 free spins on Big Bass Bonanza. You may also run into betting sites with a 100% bonus you can use on both casino games and the platform’s sportsbook.

High-roller Bonuses

Casinos offer high roller bonuses to reward players who wager large amounts of money. This bonus is aimed at highrollers and often has a larger max cap, like the 100% deposit bonus up to £500 that you can claim on Regal Wins.

Seasonal Bonuses

UK online casinos tend to be generous during holidays and special events, so keep your eyes peeled for 100% bonuses around Christmas, Halloween, Easter, Valentine’s Day, and other key dates. You may also get a special match deposit bonus on your birthday as part of the casino’s loyalty programme.

How to Obtain a Casino 100% Deposit Bonus

You’re only minutes away from claiming your very own 100% welcome bonus. If you have experience with joining casino sites, you already know the drill, but if you’re new to all of this, here’s a quick walkthrough:

step 1 Pick a Top-rated 100% Bonus Casino

Browse our list featuring some of the best online casinos in the UK and pick the one that suits you. Remember that you’re not limited to playing only on a single casino site, so make multiple choices if you wish.

step 2 Go to the Casino Site

Click the Claim Bonus button next to a casino of your choice. This will direct you to that particular casino site, where you can start the registration process.

step 3 Create an Account

Share your name, DOB, address, and other information so that the operator can confirm your identity. Once finished, follow the instructions on how to activate your account.

step 4 Make a Deposit

Head over to the cashier to make a deposit. Pay attention to the minimum deposit limits and pick a payment method that works with your bonus, as some casinos exclude specific banking options from the offer.

step 5 Use the Bonus Code

Some 100% bonuses are only available when you type in a specific bonus code. Enter the code in the relevant field if necessary.

step 6 Claim the Bonus

Your bonus should be ready once the deposit is through. Some bonuses are triggered automatically, while others must be activated manually.

step 7 Start Playing

Browse the casino’s library and start completing the wagering requirements by playing eligible games.

How to Make Most of a 100% Sign-Up Bonus: Tips and Tricks

You only have one shot to make money with your 100% welcome bonus, so you better be careful how you use it. That said, here are some general tips that should help you maximise your sign-up bonus funds:

  • Aim at a bonus with low wagering requirements: The lower the requirements, the easier it is to turn the bonus into withdrawable cash. Any 100% bonus with wagering requirements under 40x is acceptable.
  • Play games with high RTP and full wagering contribution: The best chance for you to clear the bonus’ playthrough requirements is to play games with full wagering contribution (you can find the info on wagering contribution on the bonus T&C page). Additionally, stick to playing games that offer a high return.
  • Take note of all key terms and conditions: Aside from the wagering requirements, rules such as game eligibility, payment restrictions, bonus expiry date, and max bonus winnings all play a vital role in determining the actual value of your bonus.
  • Pick a casino with frequent ongoing promotions: Don’t fixate on the welcome bonus. This is a one-time deal, and it can go away quickly. While sign-up bonuses are helpful, finding a casino that offers a steady flow of ongoing promotions is more effective, ensuring you have a continuous supply of extra funds over time.
  • Remember to play responsibly: You can be a little loose with your bonus since it’s not your money, but don’t carry over that playing style once the bonus funds run out. Establish a reasonable bankroll, stick to it, and use the casino’s responsible gambling tools if necessary.

Key Terms & Conditions of a 100% Casino Welcome Bonus Offers

Taking note of all the rules is essential in determining the actual value of the bonus and understanding how it works. Reading through the entirety of a T&C page is unnecessary, as it can be full of generic information. To save time, just focus on these specific conditions:

  • Wagering requirements: Also called playthrough requirements or rollover, these represent the number of times you need to wager the bonus before being able to claim the winnings. For example, if the bonus is 100 and the wagering requirements are 40x, you must make 4,000 worth of wagers before withdrawing. Rarely will you find a match deposit bonus with no wagering requirements.
  • Minimum deposits and maximum cashouts: The minimum deposit represents the lowest amount of money you can deposit to trigger the offer, while 100% bonuses also often have a maximum amount you’re allowed to withdraw after clearing the rollover.
  • Payment restrictions: Some casinos won’t release the welcome bonus if you make your first deposit using a particular set of payment options.
  • Eligible games: Not all games work toward completing the wagering requirements, while some don’t have full wagering contributions. When it comes to free spins, they are usually available on just one or a handful of slots.
  • Time limits: You must use the bonus funds and complete the corresponding wagering requirements within a certain period, anywhere from a few days to a couple of months.

Deposit Options Available at a 100% Bonus Casino

You can trigger a 100% bonus using a variety of payment methods available at UK casino sites. However, before you complete a deposit, read the bonus terms and conditions to make sure that your chosen payment method is compatible with the bonus. Here are some of the methods that you can choose from:

PayPal casinos logo

PayPal

A handy e-wallet that’s become one of the most popular online payment options in the last decade. Loads of PayPal casino sites in Britain offer 100% bonuses.

Pay by Phone Logo

Pay by Phone

Have a deposit be charged to your next phone bill via the Pay by Phone method. This option is quite popular in the UK, and we have a list of the best Pay by Phone casinos to help narrow your choice. However, the downside is that some bonuses can’t be triggered with this method, and you can’t make large deposits.

Trustly Payment Logo

Trustly

A well-known online banking method that enables you to make swift and effortless payments directly from your bank account. There’s a long list of casinos that accept Trustly, including those that accept this payment method for claiming bonuses.

Apple Pay logo

Apple Pay

Ideal for mobile users, Apple Pay is a secure way to link multiple cards and online banking accounts to a single wallet that you can control directly from your preferred iOS device. Apple Pay online casinos in the UK are getting more popular by the day.

Visa Payment Method

VISA and Mastercard

Good old debit cards are accepted at nearly all UK casino sites, offering an easy, secure, and reliable way to complete a 100% welcome bonus deposit.

Casino Games You Can Try With 100% Deposit Bonuses

Once you grab your 100% casino bonus UK, you can start exploring many different types of games available at British casino sites, including:

Slots

These easy-to-play reel games are entirely based on luck. They come in all shapes and forms, featuring fun themes, engaging mechanics, and high winning potential.

Bingo

Some UK casinos enable you to use their 100% bonuses on 75-ball, 80-ball, 90-ball, and other classic bingo games available on their websites. Pick your lucky numbers and cross your fingers.

Blackjack

Beat the dealer to 21 using strategy, logic, and some luck. Blackjack can be a game with a very high payout return if you know the right strategy, and it is an excellent choice for clearing those high wagering requirements.

Roulette

Bet on a single number, several numbers, or whole groups of numbers through a variety of inside and outside bets.

Baccarat

This simple, fast-paced card game has a limited number of betting options and is ideal for beginners. Wager on the Player or Banker, or go for the higher payout with a Tie bet.

Poker

Take on the dealer by creating the winning hand combinations in interesting variations like Casino Hold’em and Caribbean Stud.

Live Dealer Games

Feel the atmosphere of a bustling casino floor by playing classic casino games via HD live streams run by professional dealers.

Crash Games

The simplest of casino games where the goal is to collect the winnings before the multiplier crashes.

A Secret to Withdrawing a 100% First Deposit Bonus

To withdraw your winnings from a 100% casino deposit bonus, you first must complete its wagering requirements, which are expressed as a multiplier (e.g. 20x, 30x, 50x). The critical thing to note here is that some casinos apply the wagering requirements to the bonus money alone, while others do it on the bonus money plus the deposit:

Bonus only:

  • 30x wagering requirements
  • 100% up to 100
  • Deposit 100, get 100 in bonus money
  • You must wager 100 × 30 = 3,000

Bonus + deposit:

  • 30x wagering requirements
  • 100% up to 100
  • Deposit 100, get 100 in bonus money
  • You must wager (100 + 100) x 30 = 6,000

You’ll have a time limit for this, so make sure to wager through the bonus quickly. Also, not all games contribute fully to wagering. Slots usually contribute 100%, certain table games only contribute 5% to 20%, while others don’t contribute to wagering at all.

Top Video Slots Offered on 100% Sign-Up Bonus Casino Sites

We compiled a list of the best and most popular titles to try with your 100 welcome slots bonus. Video slots are the best games to play with your welcome bonus. There’s a ton of them to choose from, they offer a reasonable return rate and are suitable for quickly burning through those demanding wagering requirements. Here are some of our top suggestions:

Gonzo's Quest slot

Gonzo's Quest

One of the most successful releases from NetEnt, Gonzo’s Quest is a classic adventure slot you should not miss out on. Although over a decade old, it withstood the test of time with its crisp visuals and animations while boasting a solid max win potential of 3,750x. The game’s RTP stands at the industry average of 95.97%. It’s a typical 5-reel, 20-payline slot with a standard free spins game with multipliers of up to 15x. If you want to try this game, join Freebet Casino, add a valid card, and you’ll receive 5 free spins with no deposit required.

Wolf Gold slot game

Wolf Gold

Wolf Gold is another highly celebrated release and one of the most popular titles from Pragmatic Play. Even though it came out seven years ago, it’s still found in the “featured” category of many UK casino sites. This is due to the game’s timeless Money Re-Spin feature and three fixed jackpots that can be won through a mini-game once six full moon symbols appear on the reels. The game’s RTP is 96.01%, and the max win is 2,500x. Get a taste of Wolf Gold at Slots Animal with 5 no deposit free spins.

Eye of Horus

Eye of Horus

Eye of Horus is your typical Ancient Egypt title full of scarabs, hieroglyphs, and other Egypt-themed symbols. What makes this game stand out, however, is its massive win potential of 50,000x and a generous RTP of 96.31% (although beware of versions with lower RTP percentages). The game plays on a 5×3 layout, features expandable wilds, and boasts a bonus round with a chance to win extra free spins whenever you land a wild symbol. The 100 wager-free free spins on Betfred can be applied to several select video slots, including Eye of Horus.

Rainbow Riches

The Rainbow Riches series still reigns supreme on UK casino sites. The original game from Barcrest came out in 2009 and has so far received more than a dozen sequels with all sorts of interesting mechanics and extra features. However, the initial title is still a favourite to many British players. One of the best features in this slot is the Road to Riches mini-game, where you spin the wheel and progress along the trail for a chance to win a prize worth 200 times your stake. The two other bonus games, Wishing Well and Pots of Gold, can award even bigger prizes, capping out at 500x. JeffBet currently offers 50 free spins on Rainbow Riches on top of its 100% welcome bonus.

The Dog House slot

The Dog House

The Dog House is a fun Pragmatic Play video slot featuring cute pets on a 5×3 reel layout with 20 paylines. It has high volatility and an above-average return of 96.51%. The bonus round can award up to 27 free spins and comes with rewarding features like stacked high-value symbols and sticky multiplier wilds. The maximum win is 6,750 times your stake. The Dog House slot has several sequels and a Megaways version and can be found in Yeti Casino, MrQ and Kind Casino.

Fluffy Favourites

Fluffy Favourites

Fluffy Favourites is a well-known title from Eyecon featuring a lighthearted theme with stuffed toys as the focal point. It’s a simple 5×3 slot with 25 winways and a max win potential of 5,000x, although the game’s RTP is a little bit disappointing, standing at a below-average 95.38%. The Fluffy Favourites slot is known for its Toybox Pick bonus game and the pink elephant symbol that serves as the wild and doubles all winning combinations it becomes part of. You can now get 60 free spins on Fluffy Favourites by joining Bingo Loft and depositing £10 or more.

Starburst

Starburst

Starburst is a NetEnt classic that’s still among the most popular slots on UK casino sites. This simple galaxy-themed slot captivates with its crisp visuals and calming cosmic ambience. It’s a straightforward game with no free spin rounds, although it does feature expanding wilds that trigger a re-spin. Starburst has 10 paylines that pay both ways and has an RTP of 96.09%. We suggest trying this game at Barz Casino, where you’ll get a 100% match bonus up to £300 plus 50 bonus spins on Starburst.

Fire Joker

Fire Joker

Fire Joker from Play’n GO is a slot of medium volatility, 96.15% RTP, and a max win of 800x. It’s a retro-style slot with a 3×3 layout, but unlike other classic slot games, it comes with a few fun bonus features, including Flaming Respins that may trigger on non-winning spins, as well as Wheel of Multipliers that can award a prize up to 10x. Dream Jackpot currently offers 5 free spins on Fire Joker to all new UK players, no deposit required.

Other Types of First Deposit Match Bonuses

Doubling your initial deposit on a casino site is great. However, there are online casinos out there that are willing to multiply your first payment three, four, or even five times. Here’s more about these types of offers:

200% Casino Bonus

A few dozen UK casino sites give out a 200% deposit bonus. Minimum deposits go anywhere from £1 to £20, the wagering requirements are usually around 40x, and the maximum bonus amount goes up to several hundred pounds.

300% Casino Bonus

The 300% deposit bonus in the UK exists, but it’s more limiting than the 100% and 200% one. Namely, these offers usually have meagre max bonus limits, so you’ll often get a bonus along the lines of “deposit £10, get £30” like the ones on Ladbrokes and BetVictor. Still, it’s a deal worth taking.

400% Casino Bonus

The 400% first deposit bonus is very rare, but it does show up occasionally, mostly on bingo sites. The percentage may also be a sum of several bonuses spread across multiple deposits.

500% Casino Bonus

Similar to the 400% bonus, the 500% first deposit bonus is available only on a handful of British casino, bingo, and betting sites, usually limited to small £10 deposits.

Conclusion

Navigating the landscape of 100% first deposit bonuses is not easy since nearly 200 UK casino sites offer this type of promotion to new players. We hope this page will make things at least a little more convenient as we compiled all these casinos into a single list and highlighted some of the best ones. All you have to do is pick one, deposit to double your starting bankroll, and start playing.

FAQ

Should I go for the highest possible deposit match?

This depends on several factors, most notably your budget and the bonus terms. If you have a sufficient amount of money to gamble with, going for the highest possible match deposit bonus makes sense.
