What is a 400% Deposit Bonus?

Before you begin claiming all of our 400% deposit bonuses, it is important that you first understand what they are and the terms behind them. Each of our offers listed will have different rules, but all go by the same basic principle. Over the course of your casino bonus, you will see your initial deposit matched with a 400% bonus on your amount. So, for example, if you were to make a 1st deposit of £100, you would see it matched with a £400 casino bonus to use with your chosen site.

In some cases, you will be given bonuses past your 1st deposit, with some popular casinos giving players a percentage match bonus on their 2nd deposit, 3rd deposit and 4th deposit. Each deposit bonus offers different features, with no two deposit bonuses being the same. That is what makes these exclusive bonuses all the more exciting, and that is reinforced by the fact you will be able to claim all of the listed online casino bonuses. For example, an online casino bonus that features 500% deposit match bonuses will always be worth your time of day.

How can I get a 400% Deposit Bonus?

You may be thinking that a generous bonus such as this may be difficult to get your hands on. However, you would be wrong for thinking so as the process is actually straightforward to complete. You will, of course, need to have an account at your chosen reputable casino, and if you haven’t already got one, you will need to complete the registration procedure. This will require you to enter your name, date of birth and email address, amongst other details, as selecting one of their available payment methods. Payment restrictions do often apply for match bonuses such as these, so be sure to read the terms and conditions of the casino bonus to see if any deposit method restrictions apply.

You can get a 400% casino deposit bonus from all of the operators featured on our list of casino sites here once you become a registered player. More often than not, one this big will make up part of a casino welcome bonus, which is used as a way of enticing new players and, in particular, in this case, a high roller type of player. However, 400% deposit offers don’t come around all too often, so they should be snapped up as and when you have the chance to use them. To find deposit offers such as these and more, you should look on the promotions page of the site that you are using. 

Another thing to keep an eye on is the potential need to include any promo codes or bonus codes. Online casino sites will regularly include the requirement of a deposit code at the registration or deposit process for players to become eligible for the promotion they are looking to take part in. Bonus codes are becoming increasingly popular, and should players not enter them at the correct stage. They could be left unable to claim it if eligibility restrictions apply. If you forget to redeem your code at the correct time, you may have to contact their customer support team. 

Why choose a 400% Deposit Bonus?

If it hasn’t been made obvious enough already, it’s clear that this type of casino bonus doesn’t come around all too often, with a 400% deposit match bonus being a particularly generous bonus. As we previously mentioned, this would likely be as part of a lucrative welcome package and thus would be your first experience of these online gambling sites. Online gambling sites will rarely be part of a 400% casino deposit bonus outside of their new customer offers.

With that said, this is a terrific opportunity to become accustomed to your new operator, thanks to the significant bonus funds that you will be able to play with. Players will all have one common goal when it comes to playing these deposit match bonuses, and that is to turn the bonus balance into your real cash balance. Having this level of bonus funds will give you an excellent chance of doing so and plenty of playing time to compete. 

There is a casino review available for each of our selected 400% deposit bonus casino sites so you can play safely in the knowledge that you are playing with a reliable source. You can also play a range of games by joining one of the 400% deposit bonus casino sites, thus allowing you to choose your favourite online casino game. Wagering applies to these bonus winnings, as we will explain in further depth below. 

400% Deposit Bonus Wagering Requirements

Wagering requirements are regularly included as part of casino bonus offers, and when the bonus is as big as 400%, you can guarantee that they will certainly be a part of the deal. Wagering requirements determine the number of times that you must turnover your bonus winnings before you can withdraw them as real money. The size of the wagering contribution will be different for each bonus that you claim and will be decided entirely by the casino bonus offers themselves.

It is at the sole discretion of the operator themselves how large the wagering contribution must be. It could be anything from a 35x wagering requirement to a 50x wagering requirement. Once you have played through the stated amount, there will be no additional wagering requirements included on your cash balance – you will be able to withdraw some or all of it or continue playing on it.

As this is a 400% deposit bonus, it isn’t surprising to learn that your wagering contribution is likely to be quite high. There will also likely be a time limit put in place in which you must complete your selected times wagering requirements.

400% Deposit Bonus Casino Games

There is a wide range of different casino games that you will play as part of these 400% deposit casino bonuses. This includes the industry’s favourite games, including slot games, jackpot games and card games. However, many of them will be pre-selected games that have been chosen by the casino themselves, which you must play through your bonus on. So naturally, as they want people to sign up and play through their casino bonus package, these will often be popular games featured on their site. As such, you can use your bonus money on games that are both enjoyable and competitive, giving you the chance to win lucrative amounts of money.
