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.

πŸ“Œ 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 Irish 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.                

πŸ“Œ 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.  

πŸ“Œ 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.
