Last Updated: December 2024

First of all, the 400% deposit bonus is quite simply rare because there are very few gambling sites that are willing to offer that much money to their clients.

Secondly, it is possible that you will find this bonus already but will give it up if you find the terms associated with it not true. So, you may be tempted to the smaller bonuses like the 300% bonus. Therefore, apart from the size, there are other details that you must know in order to be able to choose the right width. On the other hand, for online casinos, the 400% deposit bonus is an effective marketing tool that helps to expand the customer base, which is very important in a very competitive market. But the best thing is that both sides can benefit at the same time!

Since players can’t get this offer every day, we decided to create this guide! Here, you will find all the information you need to know about this offer. Moreover, we will recommend to you the best casinos that offer this competitive offer.

What Is the 400% Deposit Bonus?

Exactly as the name suggests, a 400% deposit bonus is an offer the casino makes, to its new or registered players, to quadruple the value of their deposit.

This means that for every €1 you deposit, the casino will give you an additional €4. Thus, this means that if the player deposits €100, he will get €400 as a bonus, and his total balance will be €500.

Due to its large size, the 400% deposit bonus can be distributed to 4 or more deposits so that the player, for example, receives a 100% bonus on every deposit he makes into his casino account.

From this quick explanation, we can set two definitions related to the 400% deposit bonus, namely:

• The bonus is awarded only upon a deposit.
• The bonus percentage granted is 400%.

In addition to these two definitions, there is one more that some of you might frown upon. This is probably especially true for those of our readers who are new to the world of non GamStop casinos. No casino will only offer you a percentage bonus. It should be capped with a maximum amount. All the cash bonuses at non GamStop casinos are always accompanied by an amount of money, in conjunction with the words “up to”. This is where the wheat is separated from the chaff because this amount determines, among other things, how good the bonus offer actually is.

The whole thing will be a little easier to understand with an example for you. A casino 400% bonus up to €200 logically consists of a smaller bonus amount than a 400% casino bonus up to €400.

How We Find the Best Non GamStop Casinos With 400% Deposit Bonus?

After just a few minutes of searching the internet, you will find a large number of casinos that offer 400% deposit bonuses. However, the value of the bonus should not be the deciding criterion for you. You should be able to review and rate casinos quite objectively. Of course, we won’t leave you clueless about this. In the next part, we will explain to you exactly what is important to us in casinos. Above all, these 6 points are what determine how well a casino without GamStop will perform, and they are as follows:

License

As a general rule, and without exceptions, if the casino does not hold a valid license issued by a trusted gaming commission, you must leave it immediately. This is a strong indication that the casino is unreliable and unable to meet players’ requirements in terms of security and data protection.

Furthermore, it is possible for an unlicensed casino to host stolen, spoofed or fake gaming content. Fortunately, most online casinos already have reliable commission licenses. However, there are a minority of unlicensed sites that appear and disappear on the web on the web every once in a while. You won’t find these casinos on our site, of course, nor on any review site. So, your access to them is limited or almost non-existent. However, if you find any casino that is licensed, it is important to ignore them immediately.

You can easily check the casino license by scrolling to the bottom of the homepage and looking for the logo of the license agency. In addition, it would be great if the casino deals with an independent party to ensure that the games are fair and that the casino follows well-known regulatory rules.

Games Selection

It is important for us to offer a strong selection of games. Of course, this is especially true of slot games as they are still the most popular games among players. However, the casino should also offer a balanced group of table, card and live casino games as well.

Customer Service

One of the most important aspects that players usually overlook when evaluating a casino is customer service. It is important that the casino offers 24/7 support. One important point here, of course, is how quickly and efficiently the support agents can provide the necessary support to players.

Terms & Conditions

If the casino bonus of 400% for the first deposit is tied to the bonus conditions that are difficult to fulfil. Then, not even a very high bonus amount will be able to save the casino. The terms must be fair to both sides.

Payouts Speed

Nobody wants to wait days to get paid. When a player wins, it is understood that he wants to get his winnings as quickly as possible, and that is exactly what we are looking for.

Other Bonuses & Rewards

Of course, the 400% casino deposit bonus can be just the beginning. Various attractive promotions and seasonal campaigns should also be available. Ideally, a VIP or loyalty program for existing customers.

Fair Bonus Conditions

It is important that the terms and conditions of service in general, and the terms of the bonus in particular, are crystal-clear and detailed transparently in the casino. This way, the player can consider every aspect of the offer and make an informed decision.

As a player, you don't have to jump through hoops to find the information you're looking for. At all non GamStop casinos you can access the terms and conditions of service through the bottom margin of the main page. Also, players can access the bonus terms through the section dedicated to promotions.

It is important that the terms of the bonus are reasonable and verifiable. Although it is a difficult requirement it is important for the player's best interest. For example, if you find a bonus of 400% with a 50x wagering requirements, this means that you will not be able to generate real profits at all from the bonus. If the bonus is designed this way, the point is to put you at a disadvantage.

Positive Reputation

After confirming that the casino holds a legal license, it is important to check the reputation of the casino. If you want to gauge the reputation of a non GamStop casino that offers its players a 400% deposit bonus, you can start by browsing the online player forums. By reading the players' experiences, you can quickly get your hands on the main pros and cons of this casino.

In other words, if you see that a lot of players' complaints center around the same issue, it's definitely an aspect that you shouldn't ignore. You can also rely on our site recommendations and reviews to discover the most suitable casino – if it's been blacklisted in the past, that's the biggest red flag! Some examples:

• BC.GAME
• Cherry Gold
• Chilli 777

Verified Software

As an added sign of reliability and security, the casino must possess certifications issued by independent bodies such as eCOGRA or iTech Labs. This criterion should give you more peace of mind as it means that every game hosted by the casino offers fair and random results. So, you have realistic odds of winning.

Another certificate of trust that you should take into account is the presence of games from well-known software developers such as Microgaming, NetEnt, isoftBet, and Playtech. This means that the casino is reliable because these are some of the most reputable studios in the field.

In most non GamStop casinos you have numerous options for transferring your money to or from the player account. The casinos usually ensure that there is a good mix of classic and electronic payment methods among them. You can often find the following payment options, for example:

• Visa
• Mastercard
• Skrill
• NETELLER
• ecoPayz
• Paysafecard
• Giropay
• Bank transfers

Pros and Cons of 400% Deposit Bonus

Maybe you are already aware of the advantages and also the downsides of the 400% casino bonus, but you are not quite clear yet. The fact is that every bonus has its good and bad sides. These may be less clear in some bonuses than in others, but they are there.

So, first, the obvious benefits. Of course, with a 400% deposit bonus casino you get a lot more of your money. If you’ve already planned to make a deposit, you’re unlikely to refuse to receive quadruple the amount in your player account, right? So the 400% casino bonus means more bankroll, more playing time and more winning chances.

You may also be able to test some new games this way and maybe even find new favourites. Such an attractive bonus always has to have a catch, right? In a way, yes. First of all, such an offer often quickly persuades you to make a larger deposit than originally planned. One hopes for higher profits but can be negatively surprised by the sometimes very strict bonus conditions. Even the wagering requirements are difficult to meet due to the mostly high bonus amounts. In the end, the payout of the winnings is also limited.

If you focus on just having fun, the 400% deposit bonus casino can be of great benefit and advantage. Just don’t gamble too much and stick to your budget.

All significant advantages and disadvantages of this bonus variant can be found in the list below:

Pros

• You can test the range of games for a very long time
• The bonus can even include free spins
• You can play longer and with higher stakes

Cons

• It is linked to minimum deposit amounts
• It May have high wagering requirements
• Hard to find for UK-based players

400% Casino Bonuses Types

If you browse through the different online UK casinos not on GamStop, you will quickly notice that each casino is promoting the 400% deposit bonus in its own way. Depending on the casino policy and the terms and conditions of the offer, this bonus can be a great opportunity to win or a trap to freeze your deposit balance and deprive you of a real chance of winning. Some online casinos can add to this bonus free spins, poker chips, or even cash back on your losses to give you an extra funding boost even if you lose part of your bonus.

To make your journey easier, we have collected all kinds of casino bonuses 400% for you – here are the main types of bonus that you can find in non GamStop casinos:

This is the most popular example of a 400% casino bonus – to get this offer, all you need to do is create a new account. Then, make the minimum deposit required to activate the bonus. It is usually the minimum amount set by that particular casino.

Since it is a really big bonus, it is possible for non GamStop casinos to split it into several deposits. For example, the casino can offer a 200% bonus on the player's first two deposits.

It is also possible that this bonus will be given on the first 4 deposits that the player makes in his account.

Note that the maximum welcome bonus packages are always much higher than the maximum single deposit bonus.

This feature is definitely great for all players as it gives them more time to play and a chance to get more bonus credit without depositing a large amount at once.

When you claim a 400% casino bonus with free spins, there are usually two possible situations – either the extra spins are included in the 400% welcome bonus, or the bonus consists entirely of the free spins.

For the first type you can expect fewer free spins as they are an addition to the main course – the offer could be formed like this: “400% Deposit Bonus on 1st Deposit + 100 Free Spins on Starburst”.

However, in the second type, the free spins will be the star of the show. This means that players can expect a minimum of 400 rounds dedicated to a specific game or you can use them on different slots.

Sometimes the process of activating the 400% deposit bonus may be preceded by an additional step of entering a coupon code in a specific field while making the deposit.

This code is known as the bonus code or coupon code. However, don't worry this code can't be a secret!

You can find it on the casino promotions page or in our website reviews. After getting the bonus coupon it is important that you copy it and not type it manually.

Keep in mind that you must enter all the characters in the code correctly in order to activate the offer otherwise it will not be activated and you will not get your reward.

Promo codes usually consist of generic words, such as: “WELCOME” or “BONUS”. The bonus code can also include the brand name, such as: “BonusStrike1”.

Although most of the bonuses of online casinos are for regular players, all non GamStop casinos also have special offers for the higest depositers. Perhaps the only difference in this case is that the bonuses for large players require a higher deposit limit. For sharks and whales, this reward will be equally attractive. To activate this great offer, the player has to deposit a larger initial amount or sign up for the loyalty programme.

The great variety of bonus offers makes it possible that you could literally be spoiled for choice. However, you should be a bit careful when choosing a bonus and ultimately also for the casino itself. The highest bonus may not always be the best bonus for you. Above all, compare the bonus conditions and also look at whether the bonus comes with other extras such as free spins.

As an alternative to the 400% deposit bonus, you can also benefit from a higher bonus offer such as 500% or even 600%. For casual players and players who only play occasionally due to time constraints, lower bonus variants like 100% or 200% bonus may be a better choice.

If you are not really sure whether you want to obtain the 400% deposit bonus, then there are also plenty of alternative bonus offers that you can use instead. Below, we have given you an overview of these bonuses:

No deposit bonuses

Some welcome bonus offers are also available without a deposit. Simply register on the platform, and your bonus or casino start credit will be ready in your account instantly. The no deposit bonus will be perfect for you if you want to test the waters in the casino safely and without risking your actual money. There are plenty of casinos without a GameStop that allow their customers to use these bonuses to play and win. Certainly, this scenario is ideal for new casino players!

Reload Bonuses

It doesn’t always have to be a 400% deposit bonus, of course, there are also promotions where you get smaller bonuses that are easier to clear (e.g. offers with 50%, 100% or 200%).

Free Spins

Free spins are also a popular bonus when making a first deposit at the casino. If you are a fan of slot games, then free spins will be great for you as they are an excellent way to test new and popular games and build up your bankroll without having to deposit your own money. Although they are often limited to a handful of slot machines, they give you huge opportunities to enjoy new games and try everyone’s favourite games.

In addition to these three bonuses, some casinos also offer lottery tickets, tournaments with attractive prizes or cashback bonus promotions. So you see, the world of special promotions in real money online non gamstop casinos is big enough outside of the 400% to have a suitable offer ready for you.

100% Welcome Bonus

This is an excellent welcome offer especially for players who want to fulfill their wagering requirements quickly. The principle behind this bonus is very simple – as soon as you create a new account on the platform, and make your first deposit, the casino will double your deposit. This means that if you deposit €100, you will have an extra €100 of playing money.

This means that the total value of your balance will be €200. However, other terms, conditions and restrictions often apply first and foremost the maximum bonus amount – for example, the maximum amount you can get from the 100% bonus can be €100. So, if you deposit €500, you will only get €100.

300% Welcome Bonus

Exactly like a 400% bonu, players can get 300% bonus in different ways. For example, a player can receive this offer as a welcome bonus on their first deposit. This means that if you deposit €100 you will get €400 in total. In addition, it is also possible for players to get this bonus split on the first deposit or the first several deposits the player makes. For example, you could get a 100% bonus on your first three deposits, or you could get a 200% deposit bonus, after that a 75% deposit bonus, and finally a 25% bonus on your third deposit.

500% Welcome Bonus

Fantastic 500% Casino Bonus, especially for a new player! However, on the downside this bonus is very rare and tends to come with very high wagering requirements. For this bonus, you have to carefully read its betting terms and requirements to be sure of its quality and ability to meet your gaming goals! For example, if you deposit €100, and get a 500% bonus, the casino will give you an additional €500. This means that your total bank roll will be 600 euros. However, remember that if the wagering requirement for this bonus is too high, you will not be able to meet it and you will not be able to withdraw your winnings from this bonus.

600% Welcome Bonus

The 600% casino bonus is almost legendary in the gambling world as it is so hard to get that some prefer getting lower bonuses because it is easier to clear and more common. Once you get this legendary offer, you can expect your deposit balance to increase 6 times! However, you will always find that the wagering requirements for this bonus are higher than usual and you will not be able to easily meet them.

What Makes a 400% Deposit Bonus a Good Offer?

Regardless of the bonus percentage multiplier, there are four main factors that you need to consider before you activate the offer, and they are as follows:

The max limit is mostly in the lower three-digit range. Each bonus of the casino to its players comes with a max limit. Intuitively, the higher the limit, the better. However, note that the higher bonus value means that there are also high wagering requirements that you have to meet.

This requirement you will find in all casino bonuses without GamStop. The higher the wagering requirements, the more difficult it is to meet them.

The sign-up bonus can sometimes only be used for a certain period of time. During this period, you as a player must use the entire bonus and fulfil the rollovers. However, you should also be careful with the spin conditions because casinos can set you a deadline when you have to meet them.
