In the competitive world of online casinos, one of the most eye-catching offers you’ll encounter is the 400% welcome bonus. This type of bonus promises to multiply your first deposit by five — giving you four times your deposit amount as bonus funds. For example, if you deposit $100, you could receive $400 in bonus money, giving you a total of $500 to play with.
While this sounds extremely generous, it’s important to understand how these bonuses work, what terms are attached, and how to make the most of them. In this detailed guide, we’ll explore everything you need to know about 400% welcome bonuses: how they work, what games you can play, the pros and cons, wagering requirements, and tips to help you maximize your experience.
A 400% welcome bonus is a promotional offer provided by online casinos to new players when they make their first deposit. It means that the casino will multiply your initial deposit by four in bonus funds.
Example:
Usually, these offers come with a maximum bonus cap. For example, “400% bonus up to $400” means even if you deposit $200, you will only get $400 in bonus funds.
✅ Huge Boost to Bankroll: Get five times your deposit to play with.
✅ Extended Playtime: More funds mean you can explore games longer.
✅ Low Initial Risk: You don’t need to deposit huge amounts to enjoy a big balance.
✅ Attractive for Bonus Hunters: High-percentage bonuses appeal to players who love maximizing promotions.
1️⃣ Sign Up: Register a new account at the online casino offering the 400% bonus.
2️⃣ Deposit Funds: Use an eligible payment method to make the required minimum deposit (often $10–$20).
3️⃣ Claim the Bonus: Some casinos credit it automatically, while others require you to enter a bonus code or opt-in.

5️⃣ Meet Wagering Requirements: Fulfill the wagering conditions before any bonus-related winnings can be withdrawn.
6️⃣ Withdraw Winnings: After meeting all requirements, you can cash out the amount you’ve won.

However, it’s crucial to understand that these offers come with important terms, and meeting the wagering requirements will take strategy, patience, and discipline.
