What is a 400 Deposit Bonus?

The 400 deposit bonus is also known as a matched deposit bonus. This is because any payment made by the member has it matched by the casino at a rate of 400%. With some welcome bonuses promoting this offer, it is a first deposit casino bonus. When you make your first deposit, it triggers the bonus to add the additional 400% on top of it. The bonus can also be represented within a general ‘reload’ bonus. It’s the same principle, but it is not wholly dependent on your bonus being the first, so there are subtle differences within the terms and conditions.

Is 400% the best deposit casino bonus? Well, don’t be overly fooled by the scale. A 400% deposit bonus can still be limited or capped to an amount that any other deposit bonus promo can match. Again, this is where reading the terms gives you a greater understanding of what is being sold. A casino will indicate within the promotion what the max return is. For example, a 400% bonus up to $5,000. Now any deposit bonus can give you $5,000 in return, should the casino place this cap on it, so 400% isn’t necessarily the strongest percentage, just because it looks like it is.

What are the conditions required to be eligible for a 400 Deposit Bonus?

Not all 400 deposit bonus promotions are the same. Why? Because all the casinos providing them are different. Whilst a 400 welcome bonus in casino A, reads the same as the 400 deposit bonus in casino B, their T&Cs will have differences. The components of a bonus and their changes and meaning are what we will be dissecting in the sections below. This covers the expiry of a bonus, deposit amounts, eligible deposit methods, wagering requirement costs, winning caps, eligible games, and specialist player type.

Bonus expiry time limit

Because bonuses are ever-changing, there are limits to how long they last and must be claimed by. With welcome bonuses, they tend to have a claim by date and expiry date. Typically, a welcome bonus must be claimed within the first 7 days of forming an account. Then the offer itself must be used within the first week to 31 days. Again, the rules are broad because all casinos are different.

With general deposit bonuses, the expiry date can be beyond 31 days and can hang about for months until there is a change. Take note that some casinos will still advertise expired bonuses.

Minimum Deposit

The minimum deposit is the required value to just trigger the offer. Players can pay any amount they want beyond this, but do note that 99% of the bonuses have a max return on them. The minimum deposit value is something that will change between casinos and their promotions. For players that are perhaps wanting a budget experience, some specialist operators can provide $1 deposit casino NZ services and also $2 deposit casino NZ services as a minimum. The standard minimum deposit amounts for kiwi casinos are either $10, $20, or $30.

In some instances, bonuses can be spread over several deposits. Often 400% deposit bonuses come as a package that is spread over 3, 4, or 5 deposits. The minimum values will often remain the same, but, once again, this is not the same for every single casino online offering this bonus.

Payment Methods

There are specific bonuses to be found that are sensitive to how you make your deposits. The most common issue regarding online casino payment options can be seen within the numerous T&Cs of welcome bonuses. Often, the first method of payment must be made by a traceable method i.e., MasterCard, Visa, or Bank Transfer. E-Wallet methods are often disqualified as a payment option because of their anonymity feature. Do note, that you can use e-wallets to deposit thereafter your first payment. The reason is simple. Because the anonymity feature doesn’t tie you to the account, you could set up many accounts with the same casino to keep claiming the same welcome bonus.

Another example where payment methods are important is the Bitcoin or BTC bonus. Clearly, to claim any such offer, you can only ever use crypto as a way of depositing.

Wagering terms

Wagering terms are not fun. Wagering terms aren’t particularly fair. Wagering terms kind of suck if the truth be said. But because they are highlighted in the T&Cs regulators have passed them as players are given a fair choice to claim a bonus or not claim it. The wagering terms are requirements of further payment that must be made before you can withdraw winnings specifically made from using a bonus. Wagering requirement values differ between casinos and promotions. On average, the most common value is 35x. This means that any money won, before it is withdrawn, you must pay the bonus amount you initially received 35 times over as deposits and gamble them before wins are paid out. Now, what makes this unfair, is that you may have to pay out $3,500 if you received a $100 bonus, and only won $10.

The reason wagering requirements exist comes down to casinos being concerned that players would just use bonuses and then go elsewhere. The casinos have this logic that if a player wins, we can retain them for longer if they have to clear costs over a period of time, should they want their winnings. Some wagering cost periods can range from a week to 3 months.

Winning Limitations

What you win can be capped. The terms of a bonus will highlight the rules on what you can win with the 400 deposit bonus. Again, casinos are a business, they are in this to make money so giving as little away as possible, while being fair, is their aim. It should also be noted that when it comes to limitations, withdrawals are also capped per day. All casinos have different levels against what can be cashed out. Some operators have high thresholds at $30,000 per day, while at the lower end, you may only be able to cash out $4,000 per day. So, if you win something substantial, you might have to spread the withdrawal of it over several days.

Player Type

There are two player types that are specific to deposit-type bonuses. The first-time depositor or new member, and then you have the VIP player. With welcome bonuses, these can only be claimed by new players that are registering and depositing for the first time.

When it comes to casino VIP Programmes, they reward special bonuses and promotions that can only be claimed by those with the right VIP statuses.

Games Limitations

Your 400% matched deposit casino bonus may have limitations to what games can be played with the bonus credit. Typically, within the terms of an offer, eligible or ineligible games are listed. In some instances where ‘free’ spins are also awarded with the deposit bonus, the terms will highlight what games can be played with the spins. In most cases, but not all because of the differences in casinos. A typical deposit bonus relating to a 400 deposit bonus will be credit that is playable on slots only. Few will give you the freedom to explore live casinos Over recent years, casinos are now forming new kinds of 400 deposit welcome bonuses that are optional, giving players a choice of casino, live casino, and sports betting if provided.

How to Claim a 400 Deposit Bonus

If you wish to recoup an offer presented by a kiwi casino, you first need to make yourself an account. These are the basic steps that will take you from forming an account to being awarded your 400% deposit bonus.

  • Pick your casino and register an account.
  • Read the T&Cs of the casino bonus, and if happy, make your deposit.
  • If a bonus code is referenced in the T&Cs add this at the point of making your deposit.
  • Once your payment is cleared, the 400% additional credit is added to your balance.
  • Load the game or games that are eligible to be played and enjoy.

Note that casino bonus codes are often rarely used by casinos, but this is another reason as to why terms should always be read before you make any first deposit to begin playing.

Reasons to Choose a 400 Casino Deposit Bonus

Any bonus, be it 400 or 100, is optional and if you are happy with the terms laid out, then that should be good reason enough. The casino is willing to give you extra support and cover with your finances and the risks become somewhat lowered when playing with the casino’s money and not your own. You just need to assess the terms of the bonus and ask yourself, how do I benefit from using it? Bonuses should not be seen as a means of achieving some form of success, the extra money will prolong your game time, but it doesn’t increase the chances of winning.

Not to be negative towards casinos, but they are a business, and you need to see how bonuses benefit them, and that’s where wagering costs come into effect. It may be worth thinking about your self-management or approach to gambling if you are considering the use of bonuses. Perhaps prolonging game time is not a wise thing and this all comes down to the responsible assessments of gambling.

All New Zealand casinos now provide responsible gambling services, offering account tools that allow their members to limit what can be deposited, lost, and wagered. Players can also limit the amount of time they spend in the casino playing. All sites are also teamed with external organisations and charities like to provide professional help.

Remember, Be Gamble Aware also helps you to understand the gambling laws within New Zealand should you have any queries about your rights.

Similar Deposit Casino Bonuses

The 400% deposit bonus is one of several different percentage-matched deposit bonuses that can be found among the kiwi casino offers. This is a good thing because not all players are the same and want to have a choice. If the terms of a 400 bonus aren’t right, then you might find that a 200% deposit bonus is more suited to your needs. Throughout the course of time that online casinos have been active in the New Zealand market, the following deposit bonuses have been made available and continue to still be available as alternative options to the 400% bonus casino promotion.

100% Deposit Bonus

The most popular of deposit bonuses is the 100% Deposit Bonus. With this, you will double your money, and they do often come with ‘free’ spin rewards. Right now, many casinos are offering this bonus within the top 9 list. Please read the conditions of the offer before you commit any payment towards it.

200% Deposit Bonus

Now, a 200% deposit bonus doesn’t necessarily guarantee a greater return than a 100% bonus because it’s all about the cap limit. The 200% Deposit Bonus is slightly less popular among the kiwi casinos, but they are out there. These offers can also include bonus spins on selected games and often a 200% deposit bonus might give players a spread of deposits in which it can fully be claimed. By that we mean it might be spread over 2 or 3 deposits rather than just 1. Remember to read all the terms before recouping the offer.

300% Deposit Bonus

If you want to opt for a 300% Deposit Bonus, then these are out there but are less common that the 200% bonus. Again, offers can include bonus spins, and the full amount that is up for offer can often be claimed over a spread of deposits to make it easier for their members. Please read all terms before claiming such an offer.

400% Deposit Bonus Casino FAQs

We often get questions raised by first-time players regarding a list of matters tied to online casinos. Here we present the commonly raised queries regarding the 400 deposit bonus. We hope our answers are clear enough to satisfy any thoughts you may have about the promotional bonus.

What are the best casino bonuses?

As all bonuses are different between the casinos offering them, the best bonus is the one with the T&Cs you agree with and are favourable to you. Nothing else matters, the size and scale of a bonus are all about promotion and advertising. Ideally, you will be wanting a bonus that comes with no deposits and/or with no wagering requirements.

Which online casino has the biggest welcome bonus?

The largest welcome bonus on the kiwi market right now is Bluechip Casino. This platform is rewarding new kiwi players with a $2500 bonus with 250 bonus spins (T&Cs apply).

How do casino bonuses work?

General casino bonuses provide players with extended credit and in some cases ‘free’ spins. They are claimed by meeting T&Cs, which often require a deposit to be made first. Once payment is cleared, the player will receive their bonus to play with. Still, it is important to check the terms of the offer because bonuses are different between the many casinos hosting them.

Do you keep what you win in a 400 deposit bonus?

With all bonuses having different rules, some may allow you to keep the winnings, but others might restrict the withdrawal, but will allow players to play on with the won credit. The latter is really rare, so for the most part, what is won through a 400 deposit is kept by the player once the T&Cs have been met.

How do 400% bonus deposits work?

A 400% matched casino bonus will give you this percentage on top of your deposited payment. Now, the percentage may be split over several deposits, but there is no singular rule to how the bonus is presented and works because all bonus promotions can differ between the casinos offering them.
