Reviewing the Best 400% Deposit Bonus Casinos

Understandably, the list above only provides a snapshot of our favorite 400% deposit bonus casinos. To really help you pick the best casino for your needs, we’ve provided a mini-review of all 10 operators. That way, you can spend more time claiming a bonus and less time choosing an online casino.

1. Las Atlantis – Explore a Unique Range of Table Games

With tons of slots, 50 jackpot games, and an incredibly diverse table collection – there are plenty of reasons to choose Las Atlantis when chasing those bigger bonuses. You’ll find games you won’t find at many other casinos, including multiple Teen Patti games and Zappit Blackjack.

Crypto players are handsomely rewarded at Las Atlantis. A rewards program just for crypto users offers boosted bonuses, additional rewards and extra perks. The bonus offerings are often big but far more numerous. The casino isn’t well known for offering multiple bonuses at one time.

2. Wild Casino – Best 400% Deposit Bonus Casino

Wild Casino is a massive online casino with 370 slot games, 30+ table games, and one of the smoothest user interfaces of any online operator in the US. New games are added all the time, and with several software providers powering the collections, the variety is always rich.

The banking department has continued to improve and adapt over the years, too – once only offering a couple of cryptos, there are now around a dozen. You’ll want to stick with cryptos, too, since traditional methods incur fees and there are no card withdrawals. Large bonuses are quite common at Wild Casino, and a 400% deposit offer isn’t unusual.

3. Bovada – Excellent Range of Jackpot Games

If you have gambled online in the US before, you’ve likely come across Bovada. This is one of the biggest names in US gambling and its easy to see why. The poker section is one of the best with responsive software. Among the few hundred games on offer, there’s a huge selection of jackpot games – including those part of the Hot Drop Jackpots.

Bovada does still have a major drawback though – the cashier is quite limited with only a small handful of cryptocurrencies and few alternative methods. Although, Bitcoin payouts are typically processed in under 24 hours.

4. MyBookie Casino – Highly Intuitive Casino Gambling for Novices

MyBookie Casino is the last of the smaller operators on this list. The offerings are enough to keep casual gamers quite happy without overwhelming them with too much content. A very simple web design keeps the platform running well on mobile and ensures a high level of intuitiveness too.

Table games have some reasonably high betting limits, and we found plenty of penny slots too. There are loads of casino bonuses on offer, but they aren’t always quite as high as 400%. Numerous cryptocurrencies and the usual traditional payment limitations are present here – so expect slow bank transfers when choosing to go the non-crypto route.

5. El Royale – Request Fee-Free Payouts Using Visa and Mastercard

El Royale is a serious bonus casino. The offers are always massive, and they are often numerous. In fact, you’ll usually find around a dozen bonuses on offer at any one time. The online casino could certainly be bigger though with only 200 games – the majority of which are slots.

If you’re still unsure about cryptocurrencies and are adamant about sticking to the old ways, El Royale has you covered. Only Bitcoin can be used for crypto withdrawals but credit and bank cards are actually accepted for both deposits and withdrawals.

6. BetOnline – Highly Trustworthy Online Casino in the USA

Like Bovada, anyone who has been involved in online gambling over the past 10 years will be well aware of BetOnline. This name has been trusted for many years, and the platform has developed into a rather comprehensive gambling product. There are over 400 slots, and more than 50 table games, and the poker section is filled with lucrative tournaments and cash games.

You’ll find loads of bonuses at BetOnline, but most of them tend to only be available for the sportsbook. We really felt the cashier section could be improved for non-crypto users – however, the operator states 80% of its users use cryptocurrencies, so it is little wonder that the traditional options are limited.

7. Everygame – Best For Older Casino Games

Everygame is a very focused gambling platform. You don’t need to see the products you’re not interested in because Everygame has a site for each product – that is, a poker site, a sportsbook, and two casino sites. An extensive array of slot games can be found in Casino Classic, while everything else – including the live casino can be found in Casino Red.

A lot of older games can be found at Everygame, including video poker games and some older slots that are harder to find elsewhere. Bonuses are plentiful, with most offers being a free spins bonus of some kind. Banking is weaker than some operators with limited cryptocurrencies too.

8. BetUS Casino – Compete Against Others in Global Blackjack Tournaments

BetUS is one of the best online casinos for new players. You can quickly drop into a very intuitive sportsbook if that takes your fancy, but the online casinos are all quality and no filler. That does mean you’ll only find a little over 200 games at BetUS, but the table games are high quality, and the regular blackjack tournaments can feature huge jackpots.

The bonuses at BetUS aren’t at 400% lately, but BetUS is capable of huge offers. We’d recommend looking closely at the rollovers, though, as BetUS will sometimes set them as high as 50x.

9. Super Slots – Enjoy Exciting Modern Video Poker Titles

With more than 360 slots. You could be forgiven for thinking Super Slots is only a slot casino. However, you’ll also find 44 table games and dozens of live dealer games. Super Slots is also full of progressive jackpot games too.

This is another online casino where it is simply better to use cryptocurrencies over any other method. Traditional methods here are pricey, and bank transfer withdrawals took over 10 days during our tests.

How does a 400% Deposit Bonus Work?

A 400% deposit bonus refers to an online casino promotional offers where the casino matches the player’s deposit by 400%.

• In a nutshell, an online casino will match your real money deposit by 400%. Terms and conditions will apply.
• The bonus offer will look like the following: 400% up to $20,000.
• If the player deposits $1,000, they’ll get $4,000 in return, credited as bonus money. A $5,000 deposit would receive the maximum bonus amount of $20,000.
• Your bonus won’t exceed the maximum amount though. For example, the bonus has a $20,000 maximum bonus limit, a $6,000 deposit would still only receive $20,000 since the bonus is limited to $20,000 not $24,000.
• A rollover will also apply to a 400% deposit bonus. For example, a rollover of 30x would mean the bonus amount must be wagered 30x before any funds can be withdrawn as real money. In the above case, a $10,000 bonus wagered 30x would be a total required wager of $300,000.

Types of 400% Deposit Bonuses

Welcome Bonus

When you sign up to an online casino for the first time, you’ll be offered a welcome bonus. This is a one time offer and if you choose to ignore it, you’ll never be able to claim one again. This is important to note because the welcome bonus is typically the biggest offer a casino will ever give you. A 400% deposit bonus is more likely to be one of these.

Reload Bonus

Reload bonuses are the existing customer version of the welcome offer. The promotion is designed to entice customer to deposit again – the benefit for the player is you can get some additional bonus funds. For most reload offers at 400% or higher, the offer is usually made up of multiple deposits – such as a 100% bonus with four separate 100% deposits.

Free Spins

Usually offered in its own separate bonus, free spins can also be added to a large 400% deposit bonus as an additional perk. Imagine a bonus such as 400% up to $12,000 + 55 free spins. The free spins portion of the offer will usually have a separate rollover or win limitation. For the uninitiated, a free spins bonus is an amount of free play in selected slot games.

Best Payment Methods for 400% Deposit Bonus Casinos

As the name of the bonus would suggest, a 400% deposit bonus will require players to make a real money deposit. Furthermore, if you pick up any winnings from your bonus, you’ll want claim a quick and secure payout. Offshore casinos support numerous secure and reliable payment methods, and we detail the best methods below.

Crypto at 400% Deposit Casinos

The preferred payment method by online casinos is cryptocurrencies and considering a popular casino like BetOnline identifies that 80% of its customers use Bitcoin, its pretty popular amongst players too. Cryptocurrencies provide instant deposits and withdrawals between 24 – 72 hours. Every casino on our list is a Bitcoin casino site but there are numerous other tokens too.

eWallets at 400% Deposit Casinos

If you were to head to an online casino two years ago, eWallets were the most popular banking method. However, those days are gone and now not a single online casino on our list supports any of the eWallet’s that once ruled the industry such as Neteller and Skrill. The nearest alternative would be cryptocurrencies, as they too, are a form of digital wallet.

Traditional Payment Methods

For those not ready to use cryptocurrencies, there are still a few traditional payment methods. The problem with these methods though is that they are quite limited in their capabilities. Bank and credit cards are mostly only supported as a deposit method, while bank transfers can only facilitate withdrawals.

Advantages & Disadvantages of 400% Deposit Bonus Casinos

Promo offers that are as massive as a 400% have tons of advantages. Now that doesn’t mean there isn’t the odd disadvantage either. So you don’t just leap head first into a bonus without considering everything, we’ve identified the pros and cons below.

Advantages

• A 400% match deposit bonus is a quadrupling of your deposit amount. That’s an absolutely massive bonus and you could comfortably enjoy free play of numerous casino games without having to spend a penny of your real money bankroll.
• Big bonuses like 400% deposit bonuses are more likely to have added free spins tacked onto the total bonus. That means you can potentially walk away with some slots winnings on the side while working through the rollover of the main bonus.
• You would think an offer as big as a 400% deposit bonus would be difficult to claim but that couldn’t be further from the truth. These bonuses simply require a basic bonus code to be inputted when completing a deposit at the online casinos cashier section.

Disadvantages

• 400% deposit bonuses can be very large. This means the rollovers can feel even bigger. The standard these days is anywhere from 15 to 35x the bonus amount. A 400% bonus can be worth tens of thousands sometimes which means your overall rollover could be incredibly large.
• These bonuses can be pretty hard to come by sometimes. It’s a lot of bonus money to provide so you can understand some casinos won’t be offering a deposit match quite as big as this.

There are numerous ways to bet on each spin and a myriad of strategies to take advantage of. MyB Casino and BetOnline offer the greatest range of roulette titles.

Blackjack

Hands down, blackjack is widely regarded as the most popular casino game of all time. It is also a reasonably simple one too – players just need to get a better hand then the dealer. A score of 21 is the goal but anything over and you’ll go bust. This game also features a small range of side bets on some titles.

With regular blackjack tournaments and several table titles, XBet is the best blackjack casino for real money.

Baccarat

Offering some of the highest betting limits of any table game, Baccarat is a title that is quite popular with the high rollers. A somewhat tough game to master, players simply need to bet on who will have the better hand – the player or the dealer. Your hand can be terrible but if you bet on the better dealer hand, you’ll still win.

Craps

This popular dice game can be found at plenty of Vegas casinos, but also at numerous online operators too. Players bet on the outcome of the roll of two dice. There are numerous bet types and multiple ways to win from a single throw. This is one of several table games that you won’t find in the Live Casino and the best table game is at MyB Casino.

Keno

This easy-to-play lottery game can be played in an automated mode, so you don’t even need to play. All you need to do is choose a series of numbers and then wait to see if they’re called at random. Choose enough correct numbers and you’ll be a winner. Wild Casino offers Keno with a progressive jackpot.

Bingo

Bingo is very similar to Keno and if you enjoy one, you’ll likely enjoy the other. Players receive game cards at random and then must clear those cards. Numbers are called at random and players simply need to remove the numbers as they are called. Be the first to clear a card to win a prize. BetOnline offers several exciting bingo games.

Live Casino Games

The best live dealer casinos feature several classic table games but with an advanced twist. The games are live-streamed from studios around the world and played by users from around the world. Players can interact with the dealer in the Live Casino and other players via the live chat function. Games are streamed in full-HD, and the interface is highly intuitive.

However, you won’t be able to use most 400% deposit bonus offers in the Live Casino. That’s because most bonuses do not allow live dealer play in the terms and conditions. You won’t be able to use the bonus funds in the Live Casino and none of your bets will contribute to the rollover requirement.

Other Casino Games

If you scan around a casino site, you will notice a small section called “Specialty Games”. These titles don’t fit any standard gaming category. Expect to find unique dice games, interesting arcade titles, and fast-paced scratch cards.

How We Pick the Best 400% Deposit Bonus Casinos

While actually being able to offer a 400% match deposit bonus is the main metric when choosing the best 400% deposit casino, it is not the only metric. We also want to make sure the operator is safe, secure, and worth playing at. It is simply not good enough to just offer massive bonuses. We detail our considerations when ranking our operators below.

Low Deposit Minimums

A 400% deposit bonus needs to be accessible to all. We make sure the minimum deposit isn’t too high, even if the bonus amount is huge. That way, even casual players can still access a bonus if the minimum deposit is between $20 and $100 rather than $1000 like some large bonuses can be.

Choice of Payments

Players will always have a personal preferences. While one method may suit you, it may not suit another. That is why we look for as many banking options as possible. This means numerous cryptocurrencies and as many traditional methods that an operator is happy to accept. We also check how much traditional banking fees are and how long payouts take.

Customer Service

Poor customer support is unacceptable. We thoroughly examine the support options at each online casino. As a minimum, we expect 24/7 support, and this will always include the Live Chat feature. The very best 400% deposit bonus casinos also offer 24/7 support via email and a toll-free US phone line.

Mobile Friendly

Online casino games are designed and built with mobile gaming in mind. A high-quality casino offering a 400% deposit bonus needs to be a strong mobile performer. The casino needs to perform well on both iOS and Android devices and show no loss in content – all the same games and bonuses on the desktop page need to be present on the mobile site.

Security

Our experts always check for a long and proven history, as well as a reputable iGaming license. This combination is a great way to see how legitimate a casino operator is.
