FAQ about 400% casino bonus
🤩 Why choose a 400% casino deposit?

Quadrupling the amount you have to make bets with seems like a good enough reason on its own. If the casino breaks the bonus up in three, then you can prolong the bonus experience even longer.

Not many casinos will offer a 400% welcome bonus. Casinos know that the welcome bonus is a crucial part of the casino’s success because many players choose a casino based on the bonus. A 400% deposit bonus is meant to attract many players.

Licensing and Regulation

As stated, our experts use a vigorous list of criteria to ensure that the casino is safe. The first thing that our experts look at is the casino gambling license. The casino will usually be licensed with the Gibraltar Gaming Commission, Malta Gaming Authority, or the UK Gaming Commission. The online casino must have the license number and body that issued the license published on the site. Lastly, the operator must be regulated by a third party to ensure fairness towards the player.

Fairness Testing and Security

The 400% bonus casino should be a member of a third-party fairness testing lab. This lab will ensure that the Random Number Generator is indeed random and that the volatility is correct. Often, the casino itself isn’t registered because the game developers are. You can look for a registration number on the casino website.

The casino must have up-to-date security and SSL encryption. The safety and encryption ensure that the sensitive information that you share with the casino is confidential. You’re going to share sensitive information, such as bank details, so it needs to be kept safe.

Games from Top Developers

The top 400% bonus casinos make use of leaders in the industry of gaming development. You want to play the best games that will keep you entertained for hours. Keep an eye out for names such as NetEnt, iSoftBet, Microgaming, and Evolution Gaming, to name a few.

When you look at a casino, you should consider whether or not the casino has your favourite games. The casino could have some great titles, but if your favourites aren’t included, you won’t want to spend your time there.

Customer service is also a crucial aspect of the best online casinos. You should have multiple avenues to contact the casino, with live chat being the best method for instant assistance.

Player reviews provide insight into these aspects and can be very valuable when testing a casino and choosing the best casino for your needs.

Besides the 400% casino deposit bonus, what other promotions does the casino offer? You should be able to access various offers and join a loyalty programme. Our experts scrutinise the terms and conditions of the offers because it must be fair and understandable. You should also be able to access it easily.

You also want a casino that is legally allowed to operate in your area. Since gambling is legal in every country, the 400% bonus casino you choose must be accepted in your country.

Online casinos are also supposed to be mobile-friendly. You want a casino that has optimised its site or has an app that you can use on your mobile device. Most of the top mobile casinos online have games specifically for mobile devices, and most games are optimised to play on your mobile device.

Money, giftTerms and Conditions of Casino Bonus 400%

The terms and conditions should be fair, and you must be able to follow them effortlessly. Usually, the terms and conditions will state the betting requirements as well as the period of validity. The bonus is typically valid for 30 days after you have made your first deposit. You don’t want to make exceptionally high bets with your 400% deposit bonus, as is usually stated in the terms and conditions.

Multiple Deposit

400% casino deposit bonus - 400% welcome bonus

Some casinos require multiple deposits to qualify for the full 400% welcome bonus. Other casinos have it as a once-off. The amount that you have to deposit will be published in the terms and conditions. Some casinos can also put a limit on the maximum amount that they will match with 400%.

Betting Requirements

The terms and conditions will also state which games count towards the betting requirements and minimum and maximum bets that you can place. Usually, slots will count 100% towards the requirements, while other games might have lower percentages. When you make bets with your 400% casino deposit bonus, you must never exceed the wagering requirements. You can place a range of smaller bets to make up the betting requirements.

You will only be allowed to withdraw your winnings once you have met the wagering requirements. Remember that you can’t remove the 400% casino bonus as a cash amount, you will only have access to your winnings. Some casinos will first let you place bets with the bonus, while others will let you use your deposit.

FAQ or Customer Service

Make sure that you read through the terms and conditions. You must understand each point before you start placing bets. If there is something unclear, you can take a look at the casino’s FAQ section, where similar questions might already be answered.

Alternatively, don’t hesitate to contact customer care, who will be able to answer any questions you have regarding the 400% first deposit bonus. By keeping to the terms and conditions, you avoid being flagged as a bonus abuser.

The Math Behind the Bonus

When you have gone through the terms and conditions, you might find that the wagering requirements state that you must place a certain amount of bets with the bonus amount before you can make a withdrawal. If you want to do the math behind the bonus, let’s take a look.

Say you deposit €100, and you receive your 400% bonus. It gives you a total of €500 to wager. If the betting requirements are that you must make 20 wagers before you can withdraw, you could spend €8000 before you are allowed to withdraw your winnings. This is not always the case because you can place 20 smaller bets and only use bonus money. It does give you a good reason to understand the terms and conditions well before starting to place bets.
