A 400 casino bonus is a variation of the deposit bonus that players receive upon registration or when reloading their accounts. It’s commonly offered to new players who sign up for a real money account and complete the first deposit. For example, if you deposit $100, you’ll get $400 in bonus funds.
Beginners who want extended gameplay or more chances to play popular slot games risk-free can benefit from an online casino 400% bonus.
Unlike a 100% deposit match bonus, which only doubles your money, this promotion quadruples your deposit, translating to a bigger bankroll. Beginners who want extended gameplay or more chances to play popular slot games risk-free can benefit from an online casino 400% bonus.
And depending on the operator, you can enjoy this casino bonus on slots, jackpots, and table games, or even use it to play live dealer games.
How to Claim a 400% Casino Bonus
Claiming your casino online 400 bonus offer is easy and takes just a few steps:
Start the sign-up process: go to one of our recommended casinos, click the button on the banner and visit the casino’s official website, where you’ll find a ‘Sign up’ or ‘Register’ button.
Register and verify an account: at the online registration form, complete the process by providing your name, email, and billing information. You’ll also need to verify your account via a link sent to your inbox.
Receive your online casino 400% bonus: Some casinos require you to opt-in to the bonus offer during registration, at others you may need to activate it after logging in. If the casino 400% bonus requires a bonus code, simply copy and paste the code provided on our bonus banner.
Make a deposit: you’ll be required to make a minimum deposit of around $10 before digging into the games. Go to the site’s cashier section, pick your preferred payment method and deposit your desired amount.
Start playing casino games! Congratulations, you’re now ready to play games with your bonus. Always check the T&Cs to double-check which games count towards the bonus.
400% bonus casino terms and conditions: Signing up for a casino bonus 400 percent promo is straightforward, but will still come with specific T&Cs. Before you deposit, check the standard terms for the 400 casino bonus, such as the wagering requirement, qualifying games, and any other bonus restrictions. The wagering requirement for your online casino 400% bonus explains the number of times you’ll need to wager the bonus before you can request a withdrawal.
Types of 400% Casino Bonuses
At US casinos, the 400% casino bonus for new players is available in different packages, subject to specific T&Cs. Check out these popular promotional packages that may include a 400 bonus casino:
Welcome Bonuses: Most US casinos reward their new customers with an online casino welcome bonus, whether as a deposit match or bundled with free spins. New players must complete the registration and meet the minimum deposit requirement to qualify.
Reload Bonuses: If you’re an existing customer, you may sometimes find an operator’s 400% in the form of a reload bonus up to a specific amount. Like the welcome bonus, this offer requires a minimum deposit and is often valid on particular days.
High Roller Bonuses: Casinos reward players for loyalty and big spending habits. An example is the casino bonus 400% promotion awarded to VIPs or the site’s high-rollers. For such players, the 400 bonus casino offer may be integrated into the casino’s VIP Club or Loyalty Program. Casinos may implement specific conditions before players can get one or more 400% bonus offers, such as collecting a particular number of points or reaching a tier level.
Top Casinos Offering 400% Deposit Bonuses
Bonuses at top US casinos are made to attract new players. As the competition between online casinos heats up, the bonuses offered become increasingly rewarding. Instead of the usual 100% deposit match offers, many casinos now triple or even quadruple players’ deposits, so it’s common to see 400% bonus casino offerings.
