How to Activate the 400% Casino Deposit Bonuses Welcome Package

Usually, signing up and opening an account with one of the operators listed above is the shortest way to get your hands on this mouth-watering bonus. The registration procedure is simple and extremely straight-forward. All the casinos that we review are certified and reputable and hold one or more active licenses.

Your player account will have to be confirmed in order for you to access a gambling site. Your ID must be confirmed and some personal documents will have to be uploaded – it’s part of the law. All the casino brands must adhere to the rules and for that reason, there are strict procedures in place. The registration process does not take more than 3 minutes.

• Select your favorite operator.
• Create an account
• Make a deposit
• Play & Profit

The money that the casino offers (as part as your welcome package) will be made available to you as soon as your deposit has been confirmed. We are going to analyze an example for a better understanding. Let’s breakdown the 400% casino deposit bonuses found online and we will use Classy Slots Casino for this example. They offer a 400% match on your deposit of up to €800 as part of their welcome deal.

To qualify for the offer, a minimum mandatory deposit of €20 is needed – you are free to use your favorite payment method.. Depositing €20 will get you an €80 bonus so you will end up playing with a total balance of €100.

Your gaming balance will look like this if you:

• Deposit €10, get a bonus of €40 and play with €50
• Deposit €20, get a bonus of €80 and play with €100
• Deposit €100, get a bonus of €400 and play with €500.

Best Way to Withdraw Your Winnings

You’ve used the 400% casino deposit bonuses and you’ve doubled your money while enjoying your favorite slots. You had a lucky streak at the poker table and you were lucky playing card games – excellent. But not you want to withdraw the money that you won.

In order to do that you must wager your bonus a couple of times. Part of the terms and conditions, the bonus wagering requirements state that your bonus money needs to be played through a certain amount of times. Additionally, you will find that different types of casino games contribute to the wagering requirements in different percentages.

Slots usually contribute with 100% of your bet to said wagering conditions, while card and table games might contribute with just 10%. Some live casino games might participate with up to 20%. Playing slots is a fun and easy way to meet the bonus wagering requirements. After it is done, you can use the same banking method and place a withdrawal request – it’s fast and extremely secure.

Understanding the Wagering Requirements

It’s quite often to see players misunderstanding the concept of wagering requirements. First of all, a casino bonus is an incentive you get for joining an operator, as a new player. The bonus comes with a time limit, known as validity – your offer is usually valid for a month / 30 days.

Casinos would not be on the market for long is they decide to give every player a couple of hundred or even thousands of $$$. And for a casino to be profitable, they have to keep the players entertained and engaged. There have been times in the past when players would open an account just to get the bonus money and leave. Therefore, the rules that come with the bonus are in place to protect the casino.

We do recommend to use the welcome bonus with games that contribute 100% towards the wagering conditions – slots is a good example. Always keep in mind that accepting a bonus on your behalf is optional, you can do just fine with your initial minimum deposit, without using the casino’s welcome offer. However, you will find that there are some good 400% casino deposit bonuses out there, with extremely flexible terms and conditions and even free spins, which come with no strings attached. Take a look at our recommended operator and have fun!

The Mathematics behind the 400% Casino Deposit Bonus

As good as they sound, 400% percent deposit bonuses come with a set of conditions that need to be met before a player can actually withdraw his winnings.

 

1. Case 1 – 400% Casino Bonus on Bonus Only

The shot from our Casino Bonus Calculator below shows you the mathematical computation for earning your bonus money in a scenario, where a player deposits €100 and claims a 400% bonus with x35 wagering requirements on the BONUS ONLY.
In this first case, given the deposit amount, the bonus percentage and the wagering requirements of the casino bonus, you should play through €14,000 to be able to withdraw your winnings.

2. Case 2 – 400% Casino Bonus on Bonus and Deposit

The second case below illustrates the mathematics computed by our Casino Bonus Calculator for earning your bonus money in a scenario, where a player deposits €100 and claims a 400% bonus with x35 wagering requirements on the BONUS + DEPOSIT.

In our second example, you will notice that the wagering requirements now affect the deposit and the casino bonus. The wagering requirements will be met when you play through €17,500. Upon satisfying the terms and conditions, your funds become available for withdrawal and you can collect your winnings.
