Casinos offering 300% Bonus in the UK in 2024

Online casinos use various kinds of bonus offers to attract more customers and a 300% casino bonus is among the popular ones.

It is a type of deposit-matching bonus, which means that it is closely related to your deposit. As you can see, it is displayed in percentage, which serves as a quote that augments your deposit.

In this case, the bonus is three times bigger than your deposit. If you make £100 deposit, for example, you will get another £300 as a bonus, which means that you’ll have £400 in total to play casino games.

So far, this sounds like a dream offer, but things are actually far from ideal. There is always some catch with a bonus offer that gives the answer to all those who wonder why would an online casino give away so much money.

Why Do Casinos Give 300% Bonuses?

We can talk about this all day long but it all comes to the same thing – the online casino market is crowded and operators use different ways to find new customers and increase profit.

Casinos compete in a way that they are constantly trying to beat each other in terms of promotions and if you wonder how they can make a profit when they give three times more money than they get, here is the answer.

Just like any other promotion, a 300% bonus offer comes with terms and conditions, which usually include all kinds of limitations for players. The biggest limiting factor is the wagering requirement, but there are a few more things to keep in mind.

Wagering Requirements: This is where the story where online casinos give money ends. They may give you a 300% bonus initially but even if you win something with it, you will have to spend way more than that to become eligible for withdrawing everything you’ve won.

In most cases, the wagering requirement is high and ranges between 30x and 70x. This means that you have to wager 30 to 70 times more money to meet the wagering requirement.

For example, if the wagering requirement is 30x and you get £30 over your £10 deposit, that means that your wagering requirement sum is 30x£30, which equals £900.

Max Withdrawal/Max Payout Limit: You realize that the wagering requirement is usually very high but you still wonder what if you win more than a thousand in the case of the recent example. In that case, you would still make a profit, even after you meet wagering requirements.

Once again, online casinos are no fools and they are well-prepared for such a scenario. They always put a cap on the max withdrawal sum or payout limit, which is usually measured in a couple of hundreds.

Even if you hit a jackpot to win thousands, you won’t be able to withdraw anything above the payout limit.

Why Do Casinos Give 300% Bonuses?

How Do Casinos Match Your Deposit?

As was already mentioned, a 300% Casino Bonus is a type of deposit-matching bonus, which means that the percentage is a multiplier to your deposit.

In this case, you must make a deposit first and only after than, you will get the bonus money.

This isn’t a bonus with a fixed sum, but rather a bonus that is closely related to deposits. It’s three times bigger than your deposit, while the actual sum depends on how much you deposit the this specific casino.

Although not fixed, a 300% casino bonus in 2024 isn’t without limitations. There is a thing called a max bonus sum, which is the maximum you can get in the form of a bonus.

No matter how big your deposit is, you can’t get more than what’s the max bonus sum. In that way, online casinos prevent players from making big deposits and claiming a bonus that’s measured in thousands.

Downsides of a 300% Casino Bonus

Bonus offers come with terms and conditions that can include various limitations and restrictions.

So, when you are considering a certain bonus offer, it’s important not just to have all that bonus money in mind, but also to consider the negative sides of bonus offers.

Wagering Requirements

We have just discussed wagering requirements and realized that they are one of the biggest limiting factors when it comes to deposit-matching bonus offers.

Players need to spend big amounts of money to meet these requirements and that’s definitely a thing that negatively affects bonus offers.

Max Payout Limit

Bonus offers always come with max payout limits, so make sure to find a bonus offer that’s high in this aspect. If you don’t do that, you won’t be able to withdraw a lot of money, even if you hit a jackpot that’s worth thousands.

Downsides of a 300% Casino Bonus

Games Restrictions

One of the reasons why we pick a certain casino is because it offers an incredible selection of games.

However, our playing experience can be ruined if we don’t take a close look at the terms and conditions.

In many cases, bonus offers may come with game restrictions, in the way that not all games will be available for playing with the bonus money.

In many cases, players can’t enjoy their favorite games because of tight restrictions, so make sure to check the list of eligible games when you’re considering a certain bonus offer.

Time Restrictions

Most bonus offers have an expiry date. In that way, casinos force players to spend their bonuses quickly, so they can start making a profit.

The trouble is that you must use the bonus funds before the expiry date. Otherwise, bonus funds will be deleted from your account, even though you didn’t use it at all.

Moreover, this offer isn’t just for the first, but the second and third deposit as well, which means that you can claim up to £1.800 combined.

Besides deposit-matching 300% bonus, you also get 20 free spins.


New players in LuckofSpins Casino can claim a 300% up to £1200 and also enjoy 10% daily cashback. Min. deposit is £25 and what’s great is that the max payout isn’t fixed. The wagering requirement is at a reasonable 45x, and you only have to wager the bonus amount.

Cash Spins casino

Cash Spins casino offers a 300% up to £1000 bonus, with a minimum deposit of £20. The wagering requirement is 33x. In excess of the welcome bonus, new players also gets rewarded with 75 wager free spins on the slot Fruit Zen.

Alternative Bonus Offers

We already established that 300% bonuses are just one type of bonus offers. There are many more options around. First, there are different deposit matching bonus offers, with different percentages.

They can be higher or lower than 300% but that doesn’t automatically mean that they are better or worse. It’s important to look at the bigger picture.

In some cases, online casinos may come up with additional promotions, such as free spins. Moreover, reload bonuses have become a common thing as well.

So, it would help if you had the combined bonus value in mind. For example, a 200% bonus with additional free spins and several reload bonuses is a way better offer than a bare-boned 300% bonus.

This is just one example. There are many more alternative bonus types, such as cashbacks, in-game rewards, loyalty and VIP programs etc.

All these things have a big impact on the overall user experience, so what you need to do is to evaluate these offers combined, as a single unity. In that way, you will get a much better picture of what you’re getting and what you’re losing with each bonus offer.


To summarize, 300% casino bonuses are definitely a great thing. You get a lot of additional funds to play online casino games and that should be highly appreciated.

Still, it’s important to keep in mind that bonus offers are not ideal and that there are many downsides as well.

So, you need to be smart, to learn more about different aspects of bonus offers, so you can evaluate them properly. It’s not just about the bonus value, there are many more things under the surface.

The more you know about the negative sides, the better for you. In that way, you will learn to differentiate good offers from bad ones. That’s particularly important these days because there are so many online casinos with generous bonus offers.
