In this article, you will find all casino bonuses of at least 400% or more!
Competition between online casinos has led to an increase in bonus offers and other incentives. Typically, the higher the casino bonus the rare it is. One of the rare online casino incentives is the 400% bonus which multiplies your initial deposit by four. If you intend to try your luck on an online casino, you should consider starting with a 400% bonus when you sign up.

📌 The best 400% online casino bonuses in one place
You have come to the right place if you are looking for the best casino with a 400% bonus. The objective is to give players the best possible offers from safe and trustworthy casinos. Below you will the best online casinos with a 400% bonus when you make your first deposit. Our team has done all the hard work of testing, going through terms, and reading through player reviews.
📌 400% Casino Deposit Bonuses Explained
As its name suggests, a 400% casino deposit bonus is a deal you receive based on the deposit you make. Usually, these bonuses are offered to newly registered players. Once they create a casino account and make a qualifying deposit, they receive free cash which quintuples their bankroll. Sometimes, casinos offer a 400% bonus within a welcome package. In this case, bonuses must be claimed in the order specified by the casino.
Other than welcome bonuses, some NZ online casinos offer 400% reload bonuses. While these are rare, they exist and can boost your bankroll significantly. They are tailored for existing players, to make them come back for more.
Whichever 400% bonus offer you want to claim, you must read the rules attentively. They will tell you whether a promo code is needed, how much you must deposit, what is the maximum bonus amount you can get and how much time you have to use the free cash.
📌 How to Keep Winnings from 400% Casino Deposit Bonuses
Another rule you must pay attention to is what it takes to keep your winnings. Under the bonus terms and conditions, you will find a so-called wagering requirement, indicating how much in real money you must bet to turn the bonus into real money.
In most cases, a playthrough is set at 40x the bonus amount. However, a 400% deposit match may be subject to a higher wagering requirement. Sometimes, as high as 80x. While higher wagering requirements are understandable given the generous amount you can receive, we recommend bonuses that carry lower ones.
📌 400% Casino Deposit Bonuses: Limits and Restrictions
Casino bonuses come with certain restrictions. The casino will specify how much in bonus funds you can receive and sometimes how much you can keep and cash out. Furthermore, you won’t be able to place high bets while wagering the bonus. Instead, the operator will set bet limits at $3 or $5 per round. You must not exceed these amounts when wagering real money to complete the playthrough or your bonus funds may be null.
Time limits apply too. The casino will limit how much time you have to use the bonus and meet the wagering requirement. Timeframes can be anywhere from 7 to 30 days.
📌 Recommended online casinos
Apart from the list provided above, there are other exceptional online casinos with a standard bonus offer. Regardless, the player experience for these platforms is anything but average. Understanding that their platforms have some unique features, these casinos don't see the need to include huge bonuses. Here is a list of the top recommended casinos:
📌 Safety first
For a casino to be considered on the list of the best 400% bonus offer, it should be highly trustworthy and acclaimed by players. It is our policy to protect the safety of our visitors as well as protect our brand. Our readers need to have a pleasant experience vising one or more of our recommended sites.
A rogue casino can easily be identified by the terms they use on bonuses. Fair casinos have attainable wagering required which are within a reasonable time frame. Other bad casinos are known to payout huge jackpots in increments and this could take years Always be on the lookout and choose wisely.
📌 Casino bonuses in general
Everyone online casino player would love the chance to claim a bonus which can be in form of funds, free spins, or both. Bonuses give players a chance to try their luck on casino games without necessarily spending their actual account balance. This is merit especially if you are new to online casino gaming. Most of the 400% bonus offers are only available on this platform through the links.
📌 Why Zamsino.com?
To build trust with our online casino players, we only list licensed and accredited casinos. As stated above, only casinos that have gone through a strict testing process get on the list. Unlike most of our competitors, we take full responsibility for all online casino operators we promote.
📌 400% Casino Bonus — Advantages?
If you are on a budget, 400% casino bonuses can enable you to increase your bankroll and play longer. With 5x more money in your account than initially deposited, you can play more casino games and stand more chances to win. Also, you can use free money to play games you otherwise wouldn’t.
Use the free cash to try your luck at highly volatile slots or place bets on skill-based games to master them. The best thing about 400% bonuses are that they provide multiple options and opportunities to win.
📌 400% casino bonus — Downsides?
One downside of claiming a huge incentive like the 400% casino bonus is it results in more wagering. However, more wagering can be of great benefit depending on what kind of player you are and the situation. Go for bigger bets which have the possibility of yielding huge rewards.
📌 What to keep in mind when claiming a large casino bonus
Most huge bonuses have wagering requirements that have to be fulfilled before you can cash out your winnings. Keep in mind that these conditions vary from one casino to the other. First, check if the bonus has an expiration date. Bonuses can be cancelled if not used within a specified period. Other things to consider include games you can play with the bonus and minimum required deposit.
