How We Rate 300% Casino Bonuses

We rate 300% casino bonuses by looking at the size of the maximum bonus, minimum deposit needed, wagering requirements and other terms and conditions.  

Our experts that have years of experience in online casinos and bonuses, go through every casino and their offer. By following our rating guidelines they evaluate if the bonus is worth being on the top of our lists or towards the bottom. 

Some of the most important factors considering 300% casino bonuses are:

What Is a 300% Casino Bonus

A 300% casino bonus is a promotion by an online casino that matches your deposit amount by 300%. This will give you extra money to play with, often tied to certain terms and conditions though.

Usually the offer is set to a limit which it can't exceed. For example a typical offer could be 300% bonus up to £60. This means by depositing £20 it will be multiplied with 300% and give you £60 as bonus money. Therefore, you will now start playing with £20 of your own money + £60 bonus money, £80 in total.

Our separate casino bonus UK listing that has all the best offers available, doesn't seem to have too many of these 300% promotions though. This type of offer multiplies your deposit by multiple times which is why many casinos do not want to offer it.

You would also have to judge all the terms and conditions to make the final judgement if the offer is actually good or not. Usually as the percentage is so high, the maximum amount will be lower. This is why many of these offers haven't probably made it to the list of veyr best offers. 

300% welcome bonuses do still have their place and for many it is the perfect bonus with many pros to them. Feel free to continue and read the most clear pros and cons.

Pros and Cons of 300% Welcome Bonus


You can triple your funds to start with
Most 300% welcome bonuses include bonus spins
Low minimum requirements
You get more bang for your buck


May have higher than standard wagering requirements
Maximum amount is usually capped lower than with usual deposit offers
A rare offer type, limited availability

New UK Casinos With 300% Casino Welcome Bonus

300% deposit bonus is a great boost to start with

When you look for a new casino to play at, you need to look at certain things before making your decision. Comparing the differences in welcome offers is often the deciding factor, and for good reason. A solid welcome offer can give you a lot of extra money to play with, increasing your chances of winning. 

Given this, it is not surprising that new casinos are developing increasingly appealing welcome bonuses. After all, the competition between casinos is fierce. Casinos offering 300% deposit bonuses are becoming more common, and we expect to see many more in the future.

Browsing through the numerous welcome packages and comparing them manually is an impossible task. That's why Bojoko allows you to compare all of the newest casinos and their welcome bonuses conveniently from our dedicated new casinos page. You can further narrow the results by using our comparison tool, which allows you to filter the newest casinos based on your preferences. You can choose whatever criteria you wish, for example, the newest casinos with 300% bonuses. 

Newest 300% Casino Bonus Today

We keep an eye out for these sites and review them for you. Bingostars is the newest addition to our list of casinos offering a 300% welcome bonus. With an additional 20 bonus spins as the icing on the cake, the casino offers a generous 300% deposit bonus up to £60. Read our Bingostars casino review to learn more about it. 

Terms and Conditions of 300% Deposit Bonus

All bonuses come with terms and conditions that you must understand before claiming them. Different operators have different conditions for their bonuses, and they may even have drastic differences within their own campaigns. 

There are some main things to keep an eye out for when you browse through the terms and conditions. These naturally vary depending on the type of offer. With deposit bonuses, you should always consider the following factors:

In addition to the most important factors listed above, you should also consider betting limits, times, and payment methods. Most offers have a maximum wager of £5 and a set time period after which the bonus expires. Certain payment methods are also barred from receiving bonuses.

Comparison With Other Deposit Bonuses

Deposit bonuses are available in a variety of amounts and percentages. These offers typically start at 25% and can go all the way up to 400% casino bonuses or even 500% bonuses, though both extremes are uncommon. A 300% match bonus is already at the top end of the deposit bonus scale when compared to the other options.

100% Deposit Bonus

The most common and well-known deposit bonus is a 100% deposit bonus. Most players are familiar with these offers, which can be found at numerous casinos. The offer is straightforward: you receive the same amount of bonus funds as you deposit. 100% deposit bonuses are often matched with 100 bonus spins and a £100 maximum reward. These bonuses are commonly referred to as "100/100/100" bonuses.

200% Deposit Bonus

200% bonus casinos are the next rung up the ladder. Instead of matching your deposit, you receive double the amount in bonus funds. These offers do not typically go as high as 100% deposit bonuses in terms of amount, but they can still be found on a large scale. 

400% Deposit Bonus

A 400% deposit bonus is a less common but highly rewarding option. Who wouldn't want to start with £50 when depositing just £10?

While you get a substantial increase to begin with, you might find conversion caps and tough wagering terms with these offers. However, this does not hinder their appeal. Discover the 400% casino bonuses and find your match!

500% Deposit Bonus

At the top end of the deposit bonus scale, 500% bonuses are rare but offer the most substantial increase in funds. These bonuses multiply your initial deposit by six, giving you plenty to play with. Their downside is that the maximum amount is often limited, and the fact that you don't see them often.

You can browse our 500% bonuses page for an updated list of these deals.

Some casinos do tend to ramp up their bonuses. The first bonus is good, the second is better, and the third is even greater. These ever-increasing casino reload offers can often go up to 300%.

It's a good idea to compare bonuses from all angles in order to find the one that best suits your needs.

Casino Bonuses and Responsible Gambling

300% casino bonuses and deposit offers in general are really appealing. Casinos use bonuses to entice new players to visit their site and deposit using their welcome offers. Even when you receive bonuses, there is still a high risk of losing money. 

This is why it's important to keep in mind that casinos always win in the end and that you should always only play with money you are comfortable losing. Gambling should only be seen as a form of entertainment.


A 300% deposit bonus is an offer in which you receive triple the amount you deposited in bonus funds. These offers are usually available as welcome offers for new players.


You can get a 300% welcome bonus by finding a casino with this type of offer. We've made it simple; simply browse the available casinos from our list of 300% bonus casinos. Once you make your pick, simply click on the green "Play here" button, and signup.

Sites that offer 300% casino bonuses are usually modern casinos, whereas old-school casinos tend to offer lower deposit bonus percentages. We have listed the sites that offer 300% casino bonuses so you can simply compare them.
