How to Select the Best 400% Casino Bonus? 

One advantage that online casinos have over land-based gambling sites is that they offer massive rewards. If you are an avid casino player, you would have come across a 400% deposit match on a few occasions. The fact remains not many casinos not registered with gamstop offer this bonus. Out of these few platforms, you can choose the best by considering vital parameters like regulation and licensing, game developers, bonus terms, customer service, etc.

Payment Methods and Customer Service

You should take a look at the payment options available on the platform; the banking options must be convenient and safe. Apart from that, they must support fast deposits and withdrawals, and your preferred banking methods must be eligible for the bonus. Furthermore, customer service is a vital aspect of a non gamstop betting site; you should be able to access the support service quickly through different contact points, including live chats, emails, and phones. 

Security and Fairness Testing 

Another essential parameter to check is security. A 400% deposit match casino must adopt strict security to protect players’ personal and financial data. Most non UK gambling sites use SSL encryption technology to protect their websites from external interference. Also, the gambling site should partner with an independent fairness testing lab. This way, they can have their games tested for randomness and certified by the lab. 

What is a 400% Casino Bonus

A 400% deposit match is a casino reward designed to encourage or motivate new players to join an independent gambling site. In other words, it is offered as a welcome bonus to new players. This bonus increases players’ bankroll significantly, allowing them to play high-stake games. Players can elongate their playing time by spreading their bets. This way, they can enhance their winning chances.  

This bonus is a variation of casino rewards, which can be a welcome offer or a reload bonus. A 400% deposit bonus may be awarded as a first deposit bonus, second deposit, or third deposit. It may also form a part of a wager-free bonus.  

This bonus is easy to calculate. To know your bonus amount, multiply your deposit by 4. For instance, if you deposit 200GBP, your bonus money is 800GBP. In this case, the total bonus amount is 1000GBP. You can trigger this offer using a coupon code or get it automatically after making qualifying deposits. You should always go through the bonus terms and conditions before claiming this offer.  

Why Choose a 400 Casino Bonus

Apart from increasing your bankroll significantly, a 400% deposit match bonus enhances players’ gaming experience as it enables them to try a wide range of games without spending their money. Below are some reasons why gamers prefer this bonus: 

It boosts players’ bankroll 

This offer attracts many gamers because it increases their bankroll significantly. As stated earlier, the bonus multiples players’ initial deposits by five, providing them with more funds to play their favorite casino games. 

It is easy to claim 

Once you are satisfied with the bonus conditions and requirements, you can easily opt for this reward by meeting the minimum deposit requirement. If you need a coupon code, it will be clearly stated on the promotion page. In most cases, the bonus is activated automatically once a gamer makes a qualifying deposit.  

It is valid for slots and other RNG games 

You can use the bonus money for different slot games. It will interest you that some 400% welcome bonuses come with free spins on some specified slot titles. This provides players with enough bonus funds to play a wide array of exciting slots. 

Do Many Casinos Offer a 400% First Deposit Bonus?

A 400% deposit match is an uncommon bonus as it is available at a few no verifiation gambling sites. If you are looking for this type of traditional casino bonus, you need to expand your search. Mostly, the reward is available as a welcome bonus. 

In a nutshell, a 400% casino bonus is not available at many credit card casino sites. However, you can take advantage of this reward by registering at one of the few platforms that offer it. You should not forget to examine the bonus requirements and conditions. 

Pros and Cons of a 400% Slots Bonus 

While a 400% casino bonus can appear to be an extravagant offer, it may be a bit more complicated than you think. Therefore, it is essential to weigh the pros and cons of the rewards before you redeem them. Here are the advantages and disadvantages of a 400% casino bonus: 


It multiplies your initial deposit 

A 400% match deposit multiplies your initial deposit by four, thereby ending up with five times your deposit balance provided the bonus cap is not exceeded. This reward offers more playing funds, allowing players to apply different betting strategies to enhance their winning chances. Some of the top casino strategies include proper bankroll management, learning the rules and dynamics of new games, etc.  

It enables players to test new casino games 

With these bonus funds, gamers can test several new titles without using their money. Players feel more relaxed when practicing with new games without spending their funds. This enhances their skills and confidence, and it also boosts their overall gaming experience 


Completing the bonus wager can be challenging 

One of the disadvantages of this reward is the high playthrough requirement, which can be difficult to meet. To avoid such bonuses, check the bonus wagers before claiming the reward.  

Is the 400% Casino Welcome Bonus Sticky or Not? 

Knowing if an offer is a sticky or non-sticky bonus can help in your decision-making process. The bonus terms usually specify if a bonus is sticky or not. What is the difference between these categories of bonuses? A sticky bonus is a non-cashable reward. In other words, a player cannot withdraw the bonus except the winnings made from it. In short, you won’t be able to cash out a sticky bonus.  Conversely, you can withdraw a non-sticky bonus once you complete the wagering requirements.  

Traditional casino bonuses are typically non-sticky. To determine if a 400% casino bonus is sticky or non-sticky, check the promotion page.  


Although a 400% deposit match is not as common as other traditional bonuses, many players prefer it because it significantly increases their initial deposit. Apart from that, it allows players to try new and popular slots games and elongates their playing time. These advantages enhance players’ chances and boost their overall gaming experience.  

However, you should not jump at a 400% match bonus without going through the bonus terms and conditions as some of these offers come with strict restrictions that make it difficult to use and cash out your bonus winnings. The best way to avoid an illegitimate casino bonus is by registering at a reputable and licensed online casino. 


1) What wagering requirements do 400% deposit bonuses have? 

Juicy rewards sometimes come with strict terms, which deprive players of the benefits of the bonus. A wagering requirement specifies the number of bets required to make a bonus winning withdrawable. This requirement can be as low as 30x, and it can also be up to 60x at some gambling sites. The best way to avoid excessively high bonus wager is to check beforehand.  

2) Does a 400% welcome bonus offer free spins?

Whether a welcome bonus will come with extra spins depends on the gambling site. Some online casino complements their bonus with free spins. These additional spins are offered on some specific slot games, and they come with their terms and conditions, including eligible games, wagering requirements, etc.  

3)Is a bonus code necessary? 

The answer depends on the gambling site in question. Some USA online casinos for UK players do not require a coupon code; they award the bonus automatically once a player funds their account with an amount higher than the minimum deposit. If you need to use a bonus code, it will be clearly stated on the promotion page.   

4) Can I Claim the bonus on mobile? 

Yes, it is possible to claim a casino bonus on your mobile device. However, there are some requirements to be met. First, the platform must be compatible with a mobile device. Apart from that, you need internet-enabled mobile devices like smartphones, iPads, Tablets, etc. Once you can register, make a deposit, and play real money games through your mobile phones, you can also claim different kinds of bonuses on it, including reload bonus, welcome bonus, cashback bonus, etc.
