What Are 400% Casino Bonuses?

The 400% bonus is a type of deposit deal provided by casino operators, similar to the popular 200% casino bonus. When members meet the minimum deposit requirements for this promo, their deposit will be matched by 400% in bonus funds. For instance, the casino gives $400 in bonus money to a member who deposits $100. Australians can play a range of casino games without going over their budget with $500 in casino money. In addition, the 400% casino promotion works well for attracting visitors to the website. This kind of luxurious offer definitely stands out from the competition.

What 400% Casino Bonuses Can Bring to the Players

So, it’s quite clear why so many Australian casino users are attracted to the 400% deposit offer. The additional money is an excellent way to further the casino gameplay experience. Players can delve into more games. Also, they have a chance to win real money. Such a generous deposit promo can drastically increase a player’s winning potential. This reward is most common for new casino users. However, there are several other ways Australian players can find this offer. Below our experts listed different types of the 400% bonus online casinos offer.

With this incentive, gamblers have the chance to have an amazing time. Our team recommends reading the terms and conditions carefully before accepting this special offer. Such bonuses frequently come with stringent conditions. Also, it is important to familiarise yourself with the promotion’s terms, including its wagering requirements, betting limits, and expiration date.

How 400% Casino Bonuses Work

This incredible promotion may sound too good to be true, but it is 100% legitimate. It is one of the top online casino bonuses for players looking to extend their gameplay experience without breaking their bankroll. Casinos provide it because it attracts players to their platforms, making the promotion worth it on both sides.

Receiving this reward is very simple. Participants only need to deposit money into their casino account. In some cases, they may need to use a promo code to activate the offer. Once the transaction is completed, the casino will double the deposit, and the bonus money will be automatically credited to the player’s account.

It’s important to keep in mind that a player’s bonus funds and deposit funds will be kept separate. Every casino operates differently with how the money is spent. Some operators will require members to play through either the bonus or the deposit first. Others will combine a percentage of both into each wager until the promo is played through.

Once all of the funds have been used on casino games, players will need to meet the wagering requirements with any winnings they accumulated. Most casinos will have a tracker, allowing users to keep tabs on how close they are to being eligible to withdraw the funds.

How to Claim a 400% Casino Bonus

It doesn’t get much more exciting in the world of casino promotions than the 400% reward. Here is what you need to know about claiming the exclusive offer.

Access the Casino’s Bonus Section

Once you log into your casino account, open up the ‘Promotions/Bonus’ page. This area will show all of the available promotions. However, if you are using an exclusive Slotozilla code, you may not see the offer in this section (that’s because they are only available to our followers). But, before committing to this offer, you should check out the entire bonus section to choose one that enhances your experience.

Select Your Preferred Bonus

After reviewing the promotions, you can select the 400% deposit bonus. Review the T&Cs for exact instructions for activating the offer. Some may require you to follow a special link, while others will require you to enter a promo code. Make sure you follow the instructions to activate the promotion properly.

Specify Your Deposit Amount

The 400% deposit bonus will have specified minimum and maximum deposit limits. As with other promotions, the limits for this offer may be different from the casino’s standard minimum and maximum amounts. Before choosing your deposit amount, consider the expiration date, wagering conditions, and how much you plan to spend per session. This will give you an estimated idea of how much money is worth depositing.

Deposit Your Funds

Select one of the eligible payment methods to complete your transaction. You will be required to enter some personal details for the payment to be processed. Once all your details have been entered, hit confirm. Your deposit will be processed instantly, and funds will be in your wallet.

Claim Your Bonus

The 400% deposit bonus will be credited to your casino account after your deposit is processed. You can use these funds on pokies, card and table games, as well as eligible instant games. Some operators may also allow members to use the deposit offer on live dealer games. However, it’s essential to review the T&Cs for more information on eligible games.

Meet the Wagering Requirements

These requirements for the 400% deposit bonus will be outlined in the T&Cs. You can also discover more about which games have the higher contribution to your wagering requirements. For example, pokies typically contribute 100% of the wager, while poker may only contribute 5% to 20% of the wager.
