Rating Factors for 400% Bonus Casino Sites

Our team reviews different casino sites, and bonus offers daily. We aim to present readers with quality offers to make their gambling experience more enjoyable and exciting. We have developed a rigorous filtering system to ensure you can access only the best deals. Below we will explain our ranking criteria for different 400% welcome bonus offers in more detail.

Bonus Available on the 1st Deposit

The 400% promo would be most convenient for players if offered as a 1st deposit casino bonus. Every player appreciates a little balance boost to start their gambling journey, and a nice match percentage bonus sounds great. This is one of our main criteria, and we only put forward casino sites that offer the bonus for new depositing players.

Great Casino Bonuses Overall

While analysing an online casino website, we check all of its features and elements. Besides a good welcome offer of a 400% match deposit, we also look for other bonuses. We carefully examine the Promotions page of each casino site to see what is on offer. Only the best brands with top casino offers are featured on this page.

Low Bonus Wagering Requirements

The most important part of every bonus deal is its terms and conditions. Even the best promotion can be ruined if its playthrough requirements are too high.

Pros and Cons of 400% Deposit Bonus Deals

Online casinos offering 400% welcome bonus promos are highly sought-after by worldwide players, including Brits, and for a reason. While each operator is unique and has different features and offerings, you will notice that these sites operate similarly. They also have positive and negative sides, which we will describe below.

Why People Like Using 400% Casino Bonus Promos

Advantages of 400% Deposit Bonuses

Casino players enjoy playing at 400% deposit bonus casinos for multiple reasons. Besides the fact that you are getting 400% more of your deposit to play with, there are other benefits as well. Take a look at them below.

Often Come in Lucrative Welcome Bonus Packs

One of the main benefits of playing at online casinos with sign-up bonus offers of 400% is that they are very lucrative. Most operators offer players extra benefits in addition to the match percentage. Usually, you will get a welcome package of a 400% match bonus along with free spins on popular slot machines or even loyalty points.

New Players Risk Their Money Less

As a new player at an online casino, you don’t want to spend a lot of money from the beginning. Well, one of the benefits of playing at our recommended casinos is that you get a balance boost immediately after registration. With a 400% bonus on your first deposit, you can start playing and hopefully win awesome rewards.

Often Eligible for Popular Slot Games

Another perk of these promotions is that they are also 400% slots bonus deals. Players can claim and use them to play their favourite slot games like Starburst, Narcos, and Book of Dead. Basically, you don’t have to make any compromises when you get these promos. On the contrary, the best slot games are eligible for them.

Reload Offers Are Present

Lastly, it is very convenient that players can easily get a casino reload bonus at our recommended casinos. It means existing players can benefit from these bonuses and improve their bankroll when making subsequent deposits. Overall, this is an excellent opportunity for all players who want to maximise their casino experience.

Drawbacks of Playing at 400% Bonus Casino Sites

Negative Sides of 400% Bonus Offers

As many advantages as there are for players who decide to claim a 400% deposit bonus in UK, some disadvantages also exist. Below we will list the most significant ones for your convenience.

Some Casinos Grant Only a Total of 400% Bonus

One major downside is that some online gambling sites only give a 400% bonus as a total on the first few deposits. It means you won’t get the full amount the first time you make the minimum required deposit. Instead, you must deposit several times to claim and use the bonus fully.

May Require Promo Codes

Another disadvantage is that you may have to use a promo code to claim the promo. Some online casinos will only let you claim a 400% bonus if you enter a specific bonus code. This requirement is a major inconvenience if you don’t have easy access to promo codes for online casino bonuses or forget to enter them.

Few Casinos With Less Than 50x Rollover

Wagering requirements are the most important element of every bonus. The promo is automatically less attractive for players if they are too high and impossible to meet. The problem with the 400% bonus is that most operators attach rollover requirements of 50x or above. You can only find a few brands offering the promotion with reasonable playthrough requirements.

No 400% Bonuses Without Wagering

There is nothing more attractive for casino players than no wager casino promos. They are convenient for everyone. Players can usually activate them with a small minimum deposit, win, and withdraw their earnings immediately. But you cannot find 400% bonuses without wagering online, which is very disappointing for players.

Popular 400% Welcome Bonus Alternatives

While a 400% first deposit bonus is an excellent opportunity for players, it’s not all you can get from online casinos nowadays. Each site operates differently and has different offerings for players. So, if you have already used this welcome bonus at an online gambling site, maybe it’s time to search for alternatives. We have a few listed below.
