What Is a 400% Casino Bonus?

A 400% casino bonus is a type of bonus offered in some online casinos that rewards players with 400% of their deposit. For example, if you deposit €100, the casino will send €400 your way in bonus funds, allowing you to spin your favourite slots or play other casino games.

How 400% Maximum Bonus Works

Since the majority of 400% casino bonuses are welcome deals, it means that they’re reserved for new casino members only. So, to claim a bonus, you have to register at the casino and make your first deposit.

The casino will send the bonus funds your way, but before you can withdraw any winnings you must play at the casino. Each 400 percent bonus comes with wagering requirements which you must meet. Only after you’ve met them can you request a withdrawal.

It’s essential to see all the bonus details and read Terms and Conditions before you proceed because there could be some other restrictions that you must know about.

How to Claim a 400% Casino Bonus

To claim a 400% bonus at an online casino, you can follow the instructions below:

  1. Choose a 400% casino bonus
  2. Click on ‘Get bonus’
  3. Register at the casino
  4. Make a deposit
  5. Play

On AskGamblers, you can find bonus details for each 400% bonus that we list, so you can also take that extra step and learn about the bonus before you proceed any further.

Variations of 400% Casino Bonus

400% Casino Bonus

400% casino bonuses aren’t common, but when a casino decides to offer them, it’s usually in the form of either a welcome bonus or a high roller bonus. You can read more about them below.

Welcome Bonus

Welcome bonuses are great for players who register at the casino for the first time. Almost every casino offers a welcome bonus, but it’s up to the player to either select it or proceed without claiming it. 

With a 400% welcome deal, you get a great chance to explore the casino and play your favourite games. Keep in mind that this is usually a package deal, which means that you’ll have to make more than one deposit to make the most of it.

High Roller Bonus

High roller bonuses are created with players who like to make bigger risks and chase bigger rewards. The minimum deposit to claim a high roller bonus is usually over €100, but it can even reach €1,000 (it fully depends on the casino and its playerbase).

Requirements to Consider Before Activating 400% Casino Bonus

Before you activate your bonus and start playing, pay attention to the following: 

  • Wagering requirements - see how many times you must play through the bonus funds.
  • Game restrictions - Bonuses might be restricted to one game only (usually a slot).
  • Bonus expiration date - Your bonus funds might not be available forever.
  • Maximum cashout limit - There’s only so much you can win.
  • Minimum deposit - To activate the bonus, you must deposit the amount set by the casino.
  • Other restrictions - Look for other potential restrictions
