How can a good 400% casino bonus be recognized??

Even if a 400% casino bonus is relatively rarely available compared to other bonus offers, some still have it reputable online casinos this bonus promotion in the program.

But there is also a 400% deposit bonus some differences. In the following section I will tell you exactly what is important so that you can recognize an attractive 400% welcome bonus.

The bonus amount

the Bonus amount is what the online casinos advertise, and also what makes the special attraction for some players. However, I can recommend the The pure maximum amount should not be seen as too strong a quality criterion, if you're not a high roller looking for really big bonus payments.

  • Do not look at the maximum bonus amount if you only want to make a smaller deposit. Then other criteria are more decisive.

Because if you only want to deposit 50 euros anyway, then you can Maximum amount does not matter because then it does not affect you. Then the percentage is much more important.

What good does a 100% bonus up to 1.000 euros, if you also have one 200% casino bonus up to 500 euros if you only want to deposit 50 euros anyway and would thus get “only” 50 or 100 euros bonus credit.

The bonus turnover

This point decides everything with many bonus offers: How generous the provider shows with the turnover requirements?

Of course, it always has to be your goal, convert the bonus money into real money, so that you can cash it out again when you have won.

  • Refrain from bonus campaigns with horrendous bonus sales. You will probably never be able to withdraw a bonus with completely indisputable conditions.

Payouts are only possible if you have used the money several times and wagered it in the casino. And that's exactly where the crux of the matter lies!

Some casinos have very fair conditions and you have to convert the credit "only" about 20 times, others, sometimes more dubious online casinos pretend that the money must be used 50 times. This of course greatly reduces the chance that you will successfully meet the conditions.

The bonus period

In conjunction with the wagering requirement is also the time limit is very important. If you have to wager the money very often and you have very little time for it, then that is hardly feasible and the bonus offer receives significant deductions in the rating.

  • Time limits of 30 days are fair and desirable, but many casinos also give two weeks or even just one week.

Before activating a 400% casino bonus, you should therefore read the relevant bonus details carefully. That’s where you’ll find all important information about the bonus period. So look exactly how often you have to implement the bonus and what time frame is available to you.

Then you have to carefully weigh up whether the conditions are fair or whether the overall package is ultimately not right. From this fact you can always see very well whether it is a 400% welcome bonus, that you can really bring to a payout.

If the bonus period expires with a 400% deposit bonus, the the credited bonus amount is canceled again. For you this also means that all winnings that you have reported with the bonus money will be lost again! In practice, this must of course be avoided at all times!

Pitfalls with the 400% casino bonus

If a casino bonus allows 400 percent of additional bonus credit, it is in any case one of the most lucrative offers, which you can claim as a new player at an online casino provider.

In connection with a 400% casino bonus, however, there are also some important things that you have to pay attention to in practice. In a number of cases, a 400% welcome bonus includes some pitfalls, which in the worst case can lead to the cancellation of the bonus.

  • Always watch out for possible pitfalls so as not to jeopardize your lucrative bonus balance.

In this section I will now go over a few Hurdles and obstacles one that you often have to deal with in bonus promotions. In this way, you will receive all the important information in advance and you will certainly be able to withdraw the bonus balance including your casino winnings in practice.

Excluded payment methods

One of the most common pitfalls when activating a bonus in an online casino is the excluded Payment methods. Even before the qualifying transaction, you have to take a look at the bonus details.

In a number of cases it is the case that Deposits via the e-wallet providers Skrill and NETELLER do not result in a bonus being credited. This is also the case with some providers who provide a 400% casino bonus for new players.

If you deposit through an unauthorized payment method, the bonus will inevitably be lost!

For this reason I can only warmly recommend that you take the time to do the Wagering requirements before the first transaction to check closely on a new casino account.

Otherwise it could happen, that you do not receive the bonus and you cannot get back the bonus amount afterwards either.

Bonus code required?

To activate a bonus at the start, you need to make a qualifying deposit. In some online casinos, however, it is also the case that in addition to the deposit, you also have a special Bonus code needed.

Without the corresponding bonus code, you cannot activate the lucrative bonus balance from a 400% welcome bonus afterwards. So look carefully in the provider's bonus details to see if you need to use an additional bonus code.

  • The bonus code is often available directly from the provider and can be found in the bonus details

If you are not one hundred percent sure, you should not leave anything to chance and ask customer service. Simply go to the live chat and after a short time you will receive an answer from the support as to whether a certain bonus code is required for the respective promotion.

Limit the games

In order to be able to successfully withdraw the credit from a 400% casino bonus from your account, you first have to go to the online casino have fully met the associated bonus conditions. There are also numerous Casino games available from the relevant provider.

You should definitely check the wagering requirements beforehand, whether there are certain games that are excluded from bonus wagering. On the other hand, there are also games for which your Wagering not 100% for the fulfillment of the wagering requirements a 400% deposit bonus will be taken into account.

In most cases, however, the stakes on slots and slot machines are considered 100%. Carry table games as well as live casino games often only contributes to a very small percentage of the rollover, so that this game category is definitely not advisable with an active bonus.

However, you will always receive all information about the approved games for a 400% welcome bonus in the associated bonus details. In any case, throw before your first use take a look at the bonus conditions, so that you don't place your bets on the wrong games in an online casino.

Use restrictions

An online casino bonus is often tied to certain wagering restrictions. This also applies to an attractive 400% casino bonus. In the wagering requirements it is particularly often noted that you have an active bonus only a certain maximum amount per round may use.

You have to adhere to these betting restrictions in an online casino in any case, as violations violate the wagering requirements would. In the worst case, this can lead to the 400% welcome bonus being canceled and the profits made with it being lost again.

What are the advantages of the 400% casino bonus?

A 400% casino bonus can quintuple your account balance in the casino after your first deposit! That’s one tons of extra money, which is available to you.

So you can play with it much longer than with your mere deposit and you can also play try at higher stakes, than you usually would have done. In this way, the casino profit is also much more attractive.

Wunderino is the best example of this. With this provider you have to only make a deposit of 10 euros. You will then receive an additional 40 euros and with a total of 50 euros you can start directly with many different games!

If online casinos also get the 400% bonus combine with free spins, then you have even more of your first deposit here. However, there are often free spins with deposit in the form of other offers, so it doesn't necessarily have to be the 400% bonus.

There are disadvantages to the 400% casino bonus?

Yes there is. With the increasing percentage of the bonus offer wagering requirements also increase, which are increasingly difficult to meet. In principle, your deposit is stuck with the provider until you have implemented it or before you have lost everything.

This is a really important aspect to keep in mind when it comes to high bonus offers.

So, for example, do you take a 400% bonus up to 1.000 euros with the maximum amount of 200 euros deposit, then you must also meet the sales conditions in order to get back your 200 euros.

If, for example, they are 20 times the turnover, this means that by depositing 200 euros you will earn at least 20.Have to convert 000 euros in order to be able to pay out again at all. It is really not easy.
