The highly rewarding 300% casino bonus is one of several variations of the welcome bonus found in UK online casinos. It’s not as common as the more standard 100% promo, but it’s a lot more rewarding, as it effectively quadruples your deposit. Get details on what these promos are, how they work, their pros and cons, the types of 300% bonuses in 2024, and more.
But first, our team has done the research and found several 300% offers with low minimum deposits and reasonable wagering requirements.
Our dedicated editorial team evaluates every online casino prior to assigning a rating. These evaluations are grounded in a rigorous scoring methodology that encompasses factors such as trustworthiness, overall gambling experience, fee structures, customer support quality, and various other critical aspects.
A 300% match casino bonus is a type of deposit-based promotion where the casino matches your deposit by 300%. In other words, you get three times the amount you deposit as a bonus.
For example, if you fund your account with £100, the casino will give you 300% times that on top of it, i.e. £300. You’ll then have a total of £400 – the £100 you’ve deposited and the £300 the online casino gave you in bonus pounds.
In essence, the only requirement for obtaining this offer is respecting the minimum deposit amount and registering an account if the promo is part of the welcome bonus. Sometimes, you might also have to input a promo code while funding your account. The minimum deposit requirement is typically £10 or, in some cases, £20.
The bonus is also subject to playthrough requirements, i.e. the number of times you need to wager through your bonus funds to unlock them for withdrawal. The rollover is usually 40x, but you’ll also find 30x, 65x, and even no wagering requirements.
Pros and Cons of 300% Casino Bonuses
The 300% promo might seem like a perfect deal, as you get three times your deposit in addition to the amount you’ve transferred, but it can carry complicated terms and conditions. With that in mind, here’s an overview of its pros and cons.
Pros:
You get 3x the deposited funds as a bonus.
The minimum deposit requirement is typically low.
300% sign-up offers often come with free spins.
Many 300% bonuses have reasonable wagering requirements.
The chances of winning can improve significantly.
You get to play a lot more games than usual.
Cons:
Wagering requirements can get high at times.
There might be a low maximum winnings cap.
The offer is not as common as other match deposit promos.
How We Rate 300% Bonus Casinos
When choosing sites offering these promos, we pay close attention to the amounts covered and the bonus terms. Here’s a look at all the criteria we use in our evaluations:
Generosity and frequency: We favour sites that run generous 300% promotions, meaning ones that give more and require less, like smaller wagering requirements. The more frequently the casino offers generous bonuses, the better.
Variety and quality: The range of the promotional lineup matters greatly, as players are bound to want more promos later on. Naturally, the bonuses also need to be of higher quality, i.e. providing a good amount of bonus funds or spins without complicated wagering requirements and other terms.
Recoup chances: We always pay a lot of attention to the wagering requirements, as they are the main obstacle to unlocking your winnings for withdrawal. The lower the wagering requirements, the higher your chances. Everything 40x and below is great.
T&Cs transparency: We read through the long bonus terms and conditions to see how easy they are to follow. Moreover, we check that they are easily accessible (linked on the promo’s page) and concise.
Bonus eligibility: The more players have access to the bonus, the better. In most cases, if the promo is reserved for new players, the only requirement is that they are 18 years old. That said, they might also feature some regional restrictions and other limiting terms, which makes us rank the site lower.
Choosing the best 300% bonus casinos is easier with these criteria, but we also need to know the types of offers available on the GB online gambling market.
300% Match Deposit Bonus Types Found in UK Casinos
300% bonuses can come in many shapes and forms, most of which fall into several categories. They all share the 300% matched deposit reward, while other parts, especially the terms, can differ significantly. In the next few sections, we’ll explain what they are.
300% Casino Welcome Bonus
This is a welcome promo designed for new customers only on online casino and bingo sites. Registering an account is always a must, while other terms can differ. You can review the four types of 300% bonus right below.
Deposit £5 and Get 300% Bonus
You’re required to deposit at least £5 to get the 300% bonus. In essence, if you fund your account with the minimum amount, you’ll receive a total of £20, or £5 from your deposit and £15 as part of the bonus. You can find the £5 deposit bonus in a couple of British casinos and on some bingo sites, and you’re always welcome to deposit more if you want to get a bigger bonus.
Deposit £10 and Get 300% Bonus
This bonus is the same as the one before, but the minimum deposit amount is £10 instead of £5. This means you can deposit £10 and play with £40 in total. This bonus type is very common, as most online casinos have the £10 minimum deposit requirement. For example, this type of promo is available at Betano Casino.
Deposit £15 and Get 300% Bonus
With this bonus, you need to deposit at least £15. In other words, your account will get the £15 deposited and £45 from the bonus, a total of £60. You’ll come across the bonus in several casinos, but it’s not nearly as common as the previous type.
Deposit £20 and Get 300% Bonus
This 300% welcome bonus requires you to create an account and deposit at least £20. The promo itself is available in a couple of British online casinos. You can deposit £20 and play with £80 since it triples your deposited funds (get £60 from the bonus plus the £20 you’ve deposited).
300% Reload Bonuses
The 300% reload bonus is available only to existing customers, and it functions like almost every other casino reload bonus. In essence, you must also fund your account to claim this offer, and you get 300% of that deposit as a bonus.
Most of these offers can be claimed repeatedly, usually once a week. Other times, they are awarded once a month.
Hybrid Bonuses
This is a 300% bonus that also comes with added bonus spins, and it’s usually offered to new players. For instance, it might be a 300% match bonus up to £30 and 50 free spins. The minimum deposit requirement is still £10 in most cases, and the matched deposit is applied to it, while the spins come as an added perk.
For instance, Kitty Bingo has this type of 300% bonus, but you’ll also find it on many other casino and bingo platforms.
High Roller Bonuses
High roller 300% bonuses target players willing to deposit and play high-stakes games with large sums of money. These deals typically have better perks and cover higher maximum bonus amounts, but they also require higher deposits, typically starting at £1,000. Moreover, the wagering requirements are usually higher.
In some cases, a high roller casino bonus allows you to become part of a VIP club, leading to even better perks.
Seasonal Bonuses
Seasonal 300% bonuses are promotions offered by some casinos on special occasions. In most cases, you’ll see them on holidays and other well-known events such as birthdays (your birthday, as long as you set it in your casino account), Christmas, Easter, Halloween, Black Friday, St. Patrick’s Day, and Valentine’s Day.
This lineup covers pretty much all types of 300 percent casino bonus offers you’ll find. Let’s now move on to the actual promos you can claim.

You can find the latest casino offers like these by visiting various Gamblizard pages that cover specific bonus types. All offers come from UKGC-licensed casinos. Moreover, when you find a casino you like, you can always subscribe to its newsletter or check the Promotions page to get the latest info on new and upcoming promos.
How to Claim a 300% Bonus at Gamblizard
If you want to claim a specific 300% bonus on the first deposit, know that the process is largely the same regardless of if you are playing at a desktop or mobile casino and the bonus in question. Here’s how it usually works:
Pick a casino
Look at our curated list and choose the bonus you like the most. Base your decision on both the bonus terms and the casino’s offerings, especially games and other promotions.
Create an account
Start the registration process and input the required info. Most casinos will ask for your name, number, and address. This is all part of the standard KYC process legitimate sites have to follow.
Verify your account
The biggest part of the KYC process is verifying your identity, primarily your age and place of living. You’ll likely have to upload government-issued documents and bank statements. However, the process is automatic, so it will be completed fairly quickly.
Choose the banking option
Once your account is ready, you can go to the Deposit section. Pick the payment method you want to use for your initial deposit. Check the bonus terms once again to see if some banking options are restricted, which can often be the case with Neteller and Skrill.
Make the initial deposit
Ensure you’re depositing enough to claim the 300% bonus. You have to meet the minimum deposit requirement. You can also exceed this if the wagering requirements are relatively easy to meet and the timeframe is broad enough.
Claim the 300% bonus and start playing
With most casinos, these bonuses are awarded automatically as soon as the qualifying deposit is made. Check your balance to see if the deposit and bonus funds are there. If they are, head over to the game library, pick a title, and start playing.
Don’t forget to only play games that contribute fully towards the wagering requirements. For instance, with a slots bonus, you’ll be limited to mostly slots.
Before you claim any offer, it’s crucial to check the terms and conditions of the bonus to avoid missing something that can potentially ruin your experience.
300% Bonus Terms and Conditions
Like all casino bonuses, 300% promos also come with many terms. You can find them all in the bonus T&Cs, but here’s an overview of the most important ones:
Wagering requirements: This is the most vital term to look at, as it tells you how many times you need to wager through your bonus funds to unlock them for withdrawal. The number should be as low as possible, but everything up to 40x is relatively easy to meet.
Minimum deposit: The requirement tells you the amount you need to deposit to claim the bonus. It’s usually only £10, but since this is a large bonus, you should always deposit more to get more.
Number of deposits required: Some 300% bonuses have requirements for how many times you must deposit to claim them. However, in most cases, you only need to fund your account once.
Time limitations: Every bonus is time-limited, meaning you have a specific timeframe to claim it and a longer period, usually 30 days, to meet the wagering requirements. If you fail to comply with either, you’ll lose the bonus.
Game weighting: Not all games count as equals in the eyes of the wagering requirements. Some contribute fully, which is usually the case with slots, while others only contribute 10% or up to 50%. This is true for live casino and table games.
Payment method restrictions: Some bonuses cannot be claimed with certain payment methods, most notably Neteller and Skrill.
Speaking of payment method restrictions, keep reading to learn the methods you’ll get to use the most with these types of bonuses.
Payment Methods for Claiming a 300% Casino Bonus
Claiming a 3x casino bonus can be done with all the payment methods the casino covers for depositing, as long as the bonus terms don’t specify otherwise. It’s thus crucial to read the terms to see if such restrictions exist.
With that in mind, here’s an overview of the most common ways to claim offers:
Mastercard
Casinos with Mastercard debit card payments let you use your card to place a deposit, usually for free. Withdrawals are not always available, and you cannot use a credit card.
Visa
Online casinos with Visa are very common, so you’ll likely have a Visa card as the option for claiming the 300% casino bonus. Just like with Mastercard, withdrawals are not always possible, and you can’t use a credit card.
Google Pay
This is not a common digital payment method in UK casinos, but it is incredibly easy to use, safe, and fee-free. You should look at the top Google Pay casinos and try to find the ones with 300% bonuses.
Apple Pay
Casinos with Apple Pay are fairly common in the UK, and iOS users can get quick deposits, flexible limits, and no extra fees. However, this payment method is reserved for iOS users only and is not available for withdrawals.
Games You Should Play With the Bonus Funds From 300% Offers
UK casinos have many games, but you can’t play them all if you have a 300% bonus to use. In most cases, only specific game categories contribute fully towards the wagering requirements, so you should prioritise them.
Here’s what you should know about the most common game types:
Slots
Focus on slots if you want to meet the wagering requirements, as these game types usually contribute the most. Thankfully, they make up the biggest part of a typical casino library.
Bingogames
300% bonuses are available on bingo sites, which offer a full array of bingo and video bingo games. They all try to mimic standard real-world bingo while adding a twist of their own.
Live casino games
Live titles seldom count towards the 300% bonus rollover, so you should avoid them until you meet the wagering requirements.
Roulette
RNG roulette games often contribute less than 50% to wagering requirements, so reserve them for once you’re done with the bonus.
Blackjack
The same is true with RNG blackjack games. Live blackjack games contribute even less, sometimes 0%.
Poker
Poker is not a regular occurrence in 300% bonus casinos. Most poker games are live, and they don’t contribute much to the wagering requirements. However, you may find a few RNG video poker games.
Baccarat
Baccarat is the third most common table game in 300% bonus casinos after roulette and blackjack, contributing a minimal amount.
Crashgames
Crash games like Aviator and their unique gameplay are becoming increasingly common in UKGC casinos, but they don’t always contribute towards the rollover.
Once you’ve met the wagering requirements, you can play any game you want with your winnings. You can also withdraw if you wish. Keep reading to learn how that works.
How to Withdraw Your 300% Casino Bonus Winnings
Withdrawals are fairly simple as long as you’ve met the wagering requirements. Bear in mind that as per UKGC rules, you can always withdraw your deposited funds, but it’s best to meet the bonus requirement so you can withdraw both the bonus and deposited funds. Here’s how a typical cashout process goes:
Visit the withdrawals section: Go to your profile or the Cashier section and find the withdrawal area.
Choose the payment method: Pick one of the available payment methods and review the fees and the rules that go with it.
Input the amount you want to withdraw: Together with the amount, you’ll have to add information about the payment method required by the casino.
Confirm the withdrawal and wait for the funds to reach you: Review everything you entered to avoid mistakes, then confirm the request. The casino will then have to process (the time frame varies between casinos and withdrawal options), and the funds will appear in your account shortly thereafter.
Best Slot Games to Play With 300% Match Deposit Bonus Funds
As slots are usually the only game type that contributes fully towards meeting the wagering requirements, we’ve compiled a list of some of the most rewarding titles you can play.

Alternatives to 300% Bonuses
If you don’t like any of the bonuses on offer, or you’re simply looking for something else, here are a couple of suggestions:
A 3x casino bonus is generally one of the best casino promotions you can find, as it awards you triple the amount you’ve deposited as bonus funds. As you’ve seen from this guide, this leads to a lot of benefits.
That said, it’s crucial to read the bonus terms carefully. We’ve included only the best 300% offers on the market, but the terms might still contain something that makes the bonus less than ideal.
If you’re ready to claim an offer, review our list of promotions and their terms and make your pick. Register an account and claim the bonus, then start having fun with the games on offer while being mindful of the wagering requirements.

FAQ
Can I get a 300% casino bonus for just a £1 deposit?
Unfortunately, you’ll be hard-pressed to find such an offer as most of these bonuses have a £10 or £20 minimum deposit. In general, bonuses with a £1 minimum deposit are quite rare. Most casinos that let you deposit as little as £1 don’t offer bonuses for that amount.
Are 300% casino bonuses available to existing players?
It depends on who the bonus is for – new or existing players. You won’t find 300% promos that go both ways. Also, bear in mind that 300% bonuses for new players are more common, and those for existing players are typically awarded occasionally for special occasions or as reload bonuses.
Can I get a 300% casino bonus with no wagering requirements?
Yes, you can, but these are very rare. Those available typically come with other restrictions, like a small bonus amount of just £30. Bear in mind that the majority of hybrid 300% bonuses that come with free spins don’t have wagering requirements that apply to both the bonus funds and the free spins, only the former.
Can a 300% promo expire?
Yes, it can. Most of these offers have a validity period, i.e. the time they are available. With a typical 300% sign-up bonus, there will be a specific timeframe for claiming the bonus and a certain amount of time to complete the wagering requirements. For example, you might have three days to claim the bonus from the time you’ve signed up and then an additional 30 days to complete the wagering requirements.
What is the maximum deposit needed to get the most of the 300% bonus?
The maximum sum you need to deposit to get the most of the bonus depends entirely on the bonus terms. In most cases, the amount will be evident from the name of the bonus, like a 300% match deposit bonus up to £1,500. In this case, you need to deposit £500 to get the max £1,500 in bonus funds.
