Details on the rare 400% online casino bonus

400% Welcome Bonuses

Incentives for signing up at an online casino aren’t uncommon but, typically, the most valuable rewards are held back for the most loyal customers and a select few who have attained the illustrious rank of VIP. However, the keyword here is ‘typically’. On occasion, there are certain offers available to both new and regular players that are truly great.

Of course, online casino bonuses can come in various forms and varying values but one that rarely deviates is the welcome bonus. More often than not, casinos advertise offers that include some sort of deposit match, which usually doubles your first deposit, and a bundle of free spins. Yet, there are certain sites that blow their competition out of the water by making a 400% deposit bonus available.

Imagine signing up, making your very first deposit and receiving 5 times as much money to play with – it seems hard to believe, right? Well, there’s no need to pinch yourself; you’re not dreaming. These offers do exist and although they’re rather rare there’s little to prevent you from claiming them.

To put this into perspective let’s say a casino were to offer a welcome bonus worth 400% up to €100. You then sign up and make a deposit of €100 at which point the casino bonus would add an extra €400 to your account, resulting in your initial €100 becoming €500. You’d then be able to play all of your favourite casino games, perhaps with slightly raised stakes, without having to worry about losing anything more than what you were originally willing to risk.

However, there are still certain factors to bear in mind. There will be terms and conditions that apply to your 400% casino bonus and these may impact your ability to request a withdrawal. The bonus T&Cs will likely impose strict wagering requirements on your bonus along with several other key terms. You’ll also want to make sure that the online casino you choose to play at is trusted, secure and has a wide range of games to play. Thankfully, you can find all of this information within our online casino reviews. Therefore, we suggest that you familiarise yourself with all of the details before committing to a real money deposit.

Where Can I Claim A 400% Welcome Bonus?

400% bonus smallAs we’ve already touched upon, 400% bonus casino sites don’t appear all that often so when they do it’s always worth checking them out.

How Do I Claim A 400% Casino Bonus?

Once you’ve chosen the casino bonus that suits your personal needs it’s time to go ahead and claim it. Thankfully, it’s an uncomplicated process that should take no longer than a couple of minutes. Provided you follow the step-by-step guide below you’ll be spinning away on the most popular online slots or playing your favourite table games in no time at all.

Please note that this is a general guide and certain steps may slightly differ from one casino to the next.

  • Step 1 – Choose your casino: First of all, you’ll need to find an online casino where a 400% welcome bonus is available. We’ve made sure that all of the sites displayed throughout this page are fully regulated and licensed to ensure they provide a safe environment in which you can gamble. Therefore, all you need to do is take a look at each site and the respective offer to decide which is the perfect combination.

  • Step 3 – Select your bonus: Not all welcome offers are automatically activated when you make your first deposit. A lot of the time you’ll need to opt-in to your selected bonus either during the registration process or by confirming your intention during the deposit process.


  • Step 4 – Deposit: As soon as you’ve selected your bonus it’s time to claim the rewards. Navigate to your casino’s banking or cashier page to initiate the deposit process. A range of different payment methods will be available that you can use to fund your account. Select your preferred method, enter the amount you wish to deposit and confirm the transaction.


  • Step 5 – Play: After the casino validates your transaction the welcome bonus should appear in your account. You can now take a tour of the site and choose from many award-winning and hugely popular casino games. Load one that piques your interest to see if your luck is in!

Things To Consider When Claiming A 400% Welcome Bonus

Generic cash image smallAlthough you might be inclined to snap up these offers as quickly as possible, it’s wise to familiarise yourself with the bonus terms and conditions first. The information and stipulations contained within can help to separate the truly great offers from those that are merely masquerading as top casino bonuses.

Just as if you were to claim any type of casino bonus, the same types of terms will be attached. However, it’s their varying values and eligibility requirements that you must consider as these are what dictate both your ability to claim your bonus and then withdraw any potential winnings. Therefore, you’ll find an overview of some of the most significant T&Cs below.

  • Wagering requirements: The first thing you need to be aware of is that online casinos usually award additional money claimed from welcome bonuses in the form of bonus funds. As such, you are unable to withdraw anything classified in this manner before you meet the attached wagering requirements. To do so you must wager your bonus funds a specified number of times before the casino converts anything that remains into real money. Essentially, the lower the wagering requirement of your bonus, the better as this means you’ll have a greater chance of meeting this particular term. We suggest you look for offers with a wagering requirement of 35x or less – anything greater and it could be extremely difficult to convert your bonus funds and, ultimately, cashout any winnings.


  • Minimum qualifying deposit: Whenever you go to claim a casino bonus the T&Cs will specify how much you need to deposit to be eligible for the offer. In the case of most welcome bonuses, this amount is around €10 but, again, this can vary from site to site. Check your chosen bonus’ terms to see how much you need to add to your account to qualify so as not to miss out.


  • Payment method eligibility: There tend to be multiple payment methods that you can use to both deposit and withdraw funds at an online casino. However, not all of them are eligible for use when claiming a welcome bonus. Unfortunately, solutions such as Skrill, Paysafecard and Neteller are often excluded from casino bonuses, which means they can’t be used to trigger an offer. If you’re looking to claim one of the 400% welcome bonuses on this page you may need to use an alternative banking method.


  • Validity Period: As soon as you receive your welcome bonus incentives you’ll have a specified timeframe in which you must use them in full. During this period you will need to use any free spins and also meet the attached wagering requirements, else face the prospect of the casino voiding your bonus. Thankfully, the majority of casinos provide you with a 7-14 day window to meet these terms so it shouldn’t be overly problematic. Simply bear in mind that this can vary from one site to the next. If you don’t plan on playing through your bonus in one session look for an offer with an extended validity period.


  • Maximum win cap: Unfortunately, certain offers may include a maximum win cap. This limits how much you can win in total from your bonus. Anything above the stated amount is removed from your account once bonus play has come to an end. Of course, nobody wants restricted win potential so make sure to check if your chosen bonus limits the amount you can ultimately win.

400% Casino Bonus On Mobile

It’s not only players who prefer to play on a desktop or laptop who can claim a 400% casino bonus. Due to the increase in popularity of mobile casino gaming, you can now also reap these generous rewards on the smaller screen.

As most modern sites are fully optimised for mobile or have a downloadable app there’s very little difference between what you can experience within the various devices. You get the same great selection of casino games, regardless of your iGaming preferences, and a variety of promotions and perks as well as a plethora of different payment options. So, if you’d prefer to play whilst on the go the only things that could stand in your way of a fantastic welcome offer are a stable internet connection and a full battery.

What’s even more impressive is that as many leading game providers now optimise their creations for smartphones and tablets, players can experience the same expertly crafted visuals and feature-rich gameplay that you’d expect from a market-leading desktop computer.

Therefore, as NetEnt is one of the frontrunners in mobile casino game development, if you’re looking for somewhere to start we can recommend any of their NetEnt Touch titles, which now include the vast majority of the company’s proprietary portfolio. Simply access your preferred mobile casino using any iOS, Android or Windows device, load up any of their most popular releases and you could become the next big winner!
