How We Evaluate 400% Casino Bonus Offers

400% casino bonus evaluation factors

When ranking 400% casino bonuses, our team takes into account many factors that affect the final score and position in the overall rankings.
Here are the main ones:

  • Reliability and safety. We pay attention to the gambling site’s licensing, player reviews and our own experience.
  • Bonus terms and conditions. The important thing is to offer a 400% bonus on fair and favourable conditions for players (meaning wagering and games available).
  • RTP for bonus slots. Priority is given to those casinos that provide the best RTP in their slots, as well as their quality (popularity and reliable manufacturers)
  • Customer Support. A good casino should provide quality tech support for players because it’s always about money matters – deposits and withdrawals – and this is our priority.
  • Accept players from the UK.

Thus, our rankings include gambling brands with high scores and quality website features.

Major Sides of 400% Bonus Casinos

Without a doubt, the 400% deposit bonus is an offer for improving the gambling pastime Thanks to the increased cash and free spins, you can play more games or make bigger bets. Both improve your odds on winning!
  • Operators operate independently of UK legislation.
  • Thanks to an international license, the platforms are well protected.
  • The games are available in Europe and the United Kingdom.
  • The platforms are not connected to Gamstop.
  • Thousands of quality games from well-known manufacturers.
Sites provide easy registration using an email address or social media accounts.

Minuses of Brands With 400% First Deposit Bonus

Attractive casinos with 400% deposit slots bonuses have disadvantages:
  • Some have significant wagers that are difficult to play.
  • In addition, prizes can be sticky, meaning they cannot be withdrawn from your account. You can use them inside the casino.
  • A limited set of payment systems.
Because the platforms operate under an international license and are not subject to a local regulator, legal issues can be strained.

How to Get a 400% Casino Bonus?

Typically, to get a 400% deposit bonus from a casino, all you need to do is deposit a certain amount (usually described in the T&Cs).
Conveniently make a deposit, such as Pay by Phone not on Gamstop, and complete your registration on the site.
The bonus will be given to you automatically, and all you have to do is use it wisely (well, or lose it all at once).

How to Withdraw My Winnings using 400% Welcome Bonus?

The casino usually puts wagering requirements on the bonus in order to withdraw the funds.
These requirements are usually:

  • wagering (from 1 to …)
  • minimum cashout sum (meaning you need to reach some point in your winnings)
  • Wagering period (e.g. 7 to 30 days)

Next, you need to submit a withdrawal request in your personal account, provide the casino details as needed and select your preferred method of payment.

Who is offered a 400% Deposit Bonus?

Usually, this bonus is given to new players, but in some casinos it can be a bonus on 2nd or even 3rd deposit – it all depends on the size of the first bonus, and then the size of the bonus goes on descending.
So if the welcome bonus is 800%, it’s possible that the second or third bonus could be 400%.
