What Is The Meaning Of A 400 Casino Bonus?

Matching the first deposit of new members is a pretty common practice in the iGaming industry. And as you all know, the rate of this match offer is usually 100%, most of the time. Well, there are online casinos out there who are ready to offer much higher rates, like 400%. This is the same welcome bonus you can find at every online casino, but instead of doubling your gaming budget, you are quadrupling it. By using a 400 signup bonus casino deal, you can easily play with four times the starting budget. For example, if you deposit 100 EUR, your account will get credited with 400 EUR, so you will be able to play with 500 EUR. Sounds like a sweet deal, right?

Well, it is actually a sweet deal. 400 bonus casino offers are rare, but they exist. They are probably the best welcome bonus for high-rollers, due to their high upper limits. For example, if you are ready to deposit 1.000 EUR at the beginning, you can easily get a 4.000 EUR bonus. They are good for low-rollers too, because by depositing only 30 EUR, for example, you still get to play with 120 EUR. In short, 400% casino bonus deals are good for you, and by reading this article, you can find the best 400 casino bonus deals available at the moment. However, we must mention an important thing before we continue: Do not expect to find a $400 free casino slots no deposit bonus deal. While no deposit bonuses exist, no online casino will give you 400 USD/EUR just for becoming a member. 400% casino bonus offers will always require making a deposit.

Why Do 400 Deposit Bonus Casino Offers Exist? What Is The Catch?

There is no catch, you will really quadruple your first deposit amount. In other words, the online casino will really match the deposit by 400%. But, you won’t be using your bonus funds immediately –  this is the “catch” if you want to call it like that. Because of the requirement, the online casino “guarantees” that you will stay as a member (and keep playing games) for at least a month, so this is what they get in return. We will explain what the wagering requirement is below.

In addition, 400% of casino bonus offers are a great marketing tool. Imagine seeing a promotion like this: 400 % bonus casino up to … $. Now, fill in the dots with thousands of dollars/Euros – you will be interested in an offer like this, right? Through 400 signup bonus casino offers, online casinos gain hundreds of new members, and no business can turn down this kind of opportunity.

400 Bonus Casino Wagering: How To Unlock Your Funds

All welcome bonuses (yes, even the casino $400 no deposit bonus offers) require completing a wagering requirement. This is mandatory for 400 match bonus casino sites – if there was no requirement, players will simply cancel their accounts after claiming the bonus. So, what is this requirement and how does it affect you? Simply put, wagering requirements ask you to wager the bonus amount you get by a certain rate. Here is an example:

  • You get 1.000 EUR bonus from a 400 casino match bonus
  • You will be able to see your bonus funds on your profile page, but they will be locked. You cannot use them to play games or withdraw them.
  • Let’s say the wagering rate is 30x, which is a pretty common rate.
  • This means you must wager the bonus amount 30 times in advance. In other words, you must reach a wagering total of 30.000 EUR first (1.000 x 30).
  • Wagering means depositing the money and use it to play games. So, you must deposit 30.000 EUR and use all of it to play casino games. If you deposit 30.000 EUR but do not use it, you won’t be able to complete the requirement.

Remember that each online casino will have a different wagering rate for its 400 casino bonus offer. As a player, you should look for the lowest rates. The industry average is in between 30x and 40x, so you can expect to see rates in this range. In addition, please note that not all casino games contribute the same amount towards the requirement. Usually, only slot machine wagers contribute 100%, and this rate is much lower (sometimes zero) for other games. Check the terms and conditions of a 400 casino bonus offer to see the actual contribution rates.

Best Casino Online 400 Bonus Offers You Can Find In 2019

Let’s continue with the best online casino sign up bonus offers that give you a 400% match rate. The welcome bonuses below allow you to get up to 4.000 USD for free, and some of them do not even have a maximum limit – no matter how much money you deposit, the casino will match it by 400%. Sounds good, right? Most of these offers belong to US casino sites – high match bonus rates are much more common in the United States. However, there are European casino sites too that offer the same rate, and sweeten the deal with a couple of free spins. So there are advantageous 400 casino bonus UK deals too if you are looking for them. (But note that 400 casino bonus PayPal deals will be quite rare among US casino sites, as PayPal is not a suitable gambling payment method in the United States.) In any case, these are the best online casino bonus 2019 offers you can find right now.
