      What Is a 400% Deposit Bonus?

      A 400% deposit bonus is one of the most generous casino offers you can find, giving you four times the value of your deposit in bonus funds, up to a certain amount. While these promotions are rare, they can provide a huge boost to your bankroll right from the start.

      For example, you might come across a 400% casino bonus up to €250. If you deposit the full €250, the casino will match it with an additional €1,000 in bonus funds. That gives you a total bankroll of €1,250 to kick off your play (your €250 cash deposit plus the €1,000 bonus).

      Pros and Cons of 400 Deposit Bonus Casino

      A 400 deposit bonus might make you feel like the gaming gods are shining on you. However, the reality is that every bonus has its pros and cons. Here are some to take into account when it comes to claiming an online casino 400 bonus. 

      ✔️PROS❌ CONS
      Quadruples your bankroll. Having 5x the amount you invested is a great return, and the perfect way to start life at a new casino.Wagering requirements. Most 400 deposit bonuses come with wagering requirements, so make sure you’re okay with these before accepting the bonus.
      Low minimum deposit. Many online casinos still allow you to get started with as little as €‎10, so you can benefit from the bonus while still playing on a budget.A very rare offer. A bonus this generous is understandably hard to find. 
      Try new games. A 400% deposit bonus gives you a larger bankroll so you can play more casino games without risking much of your own money.Max cashout limit. Some 400% bonuses have low cashout limits, as casinos use them to balance the high value of the offer.
      Often bundled with free spins. Many 400% offers come with an extra free spins bonus on top, giving you even more ways to try new slot games. 

      How to Choose a 400% Bonus Casino

      The first step in getting your hands on a 400% online casino bonus is deciding where to play. So how do you choose? Here’s a simple 5-step process to find the right 400% bonus casino to start with.

      How We Rank and Review 400% Bonus Casino Sites

      When you look at the fine print, no two 400 deposit bonus offers are exactly the same. We review each casino bonus carefully to make sure they give you value and aren’t impossible to claim.

      The Mr. Gamble team uses an approved list of criteria to make sure you get reliable facts. Each factor is reviewed objectively, with no promotion, focusing on the essentials you need to know when making a casino account.

      Casino Licence and Security

      Toggle content

      We only list casino 400 deposit bonus offers that operate under valid gambling licences (e.g. Curacao or MGA). 

      We check for SSL encryption, regulated payment providers, iGaming legitimate software providers, and GDPR compliance. The latter ensures your personal and financial data is protected, offering peace of mind that you’re dealing with a legally operated and reputable casino platform.

      Fair Bonus Terms

      Toggle content

      Our review examines wagering requirements, maximum allowable winnings, minimum deposit requirements, and time limits tied to the bonus offer. 

      We prioritise any casino deposit bonus of 400% that provides usable, transparent terms rather than restrictive conditions. For example, clear wagering requirements and withdrawal limits will always be better than vague casino promotions. 

      Eligible Games

      Toggle content

      The best 400 bonus casino sites cover a multitude of online casino games from top providers. 

      We assess the quantity and quality of eligible games under the offer, looking at slots, table games, live casino games, and any other eligible mini games. Sites offering a broad selection from respected software providers (e.g., NetEnt, Microgaming) score higher than brands with tight game restrictions.

      Payment Methods

      Toggle content

      400 casino bonuses mean nothing if the payment methods are too restrictive to access them. To combat this, we analyse the deposit and withdrawal options available, looking for debit cards, e-wallets, bank transfers, and cryptocurrencies. 

      We also check through processing times, transaction fees, minimum deposit limits, and whether the deposit match bonus works with all payment methods. Overall, a diverse and efficient payment infrastructure with secure payment gateways earns top marks.

      User Experience

      Toggle content

      We also look at whether the 400% bonus online casino has a good user experience. 

      The best online casinos have swift loading speeds, easy navigation, mobile compatibility, and intuitive usability for all players — even those who aren’t tech-savvy. Online casino sites that are laggy or confusing don’t make the cut.

      Reputation and Fairness

      Toggle content

      Most casinos play by the rules, but some sites miss the mark. 

      To guarantee a safe experience, we consider player feedback and independent audits (from third parties like eCOGRA). We also look for sites with a history of prompt payouts and fair dispute resolution.

      Different Types of 400% Bonuses

      A casino 400% bonus can come in a few different forms, from welcome deals for new players to reload offers for regulars.

      To help you spot the best casino bonuses, we’ve broken down the most common types of 400% offers you’ll come across.

      400% First Deposit Bonus

      A 400% first deposit bonus casino offer is the simplest way to see how a 400% promotion works. When you make your very first deposit – as long as it meets the minimum amount set in the terms and conditions –  the casino will boost it by 400%. This makes a 400 first deposit bonus casino deal one of the most powerful welcome offers, giving you a huge amount of extra funds to start playing with right away.

      400 Welcome Bonus Casino Deals

      A 400% welcome bonus casino offer is designed especially for new players. To claim it, you simply need to create an account and make your first deposit – after that, the bonus is credited to your balance. 

      In some cases, a 400 welcome bonus casino deal may also be part of a larger casino welcome bonus package, where you’ll find extra perks such as free spins or reload bonuses alongside the deposit match.

      400 Match Bonus Casino Offers

      400 casino bonus offers online

      A 400% match bonus casino deal works much like a first deposit bonus, but it isn’t always limited to new players. While a 400% match bonus casino promotion is most often seen as part of a welcome offer, some sites also extend it to existing players through reload bonuses.

      Hybrid Bonuses 

      A hybrid 400 casino deposit bonus combines different bonus types into one promotion. For example, alongside the 400% deposit match, you may also receive free spins or cashback rewards. 

      Modern hybrid deals allow players to benefit from both extra funds and additional perks, creating a more varied bonus package compared to a standard match offer. Ideal if you’re keen to use bonus credits on different games.

      High Roller Bonuses

      Now for one of the most exclusive bonuses: a 400% high roller bonus.

      This type of 400% deposit bonus casino deal is tailored for players making larger deposits. These promotions usually come with higher maximum bonus limits, but you’ll need to wager more to get your winnings. These tend to be better for experienced players looking to maximise their bankroll from the start.

      400 Bonus Codes

      Some online casino sites require a 400% bonus code to unlock the offer and boost your deposit. These codes are usually short strings of letters or numbers that you enter during sign-up or at the cashier when making your deposit. They’re also often used for no deposit promotions at many sites.

      You’ll usually find a 400 bonus code on the casino’s homepage, promotions page, or in newsletters. Many trusted bonus codes casino sites also collect and list the latest deals in one place. Just be sure to type the code exactly as shown – otherwise, your bonus might not activate.

      How to Claim a 400% Deposit Bonus

      The process of claiming a 400 deposit slots bonus is almost the same at every online casino. Follow these simple steps to unlock your bonus, start playing, and even have a shot to win real money:

      1. Choose a casino to play at – Pick one from our recommended list of 400% deposit casinos and get started.
      2. Read the T&Cs – Check the bonus terms carefully, including wagering requirements, eligible games, and any limits.
      3. Create your account – Hit the sign-up button, enter your details, and set up your profile.
      4. Deposit money – Head to the cashier, choose a safe payment method, and fund your account with the qualifying amount.
      5. Claim your bonus and play slots – Once activated, your bankroll will be multiplied by 5x, giving you extra funds to explore the casino and play slots or other games.

      Key Terms and Conditions of a 400% Deposit Bonus

      A 400% casino bonus is undoubtedly a very attractive offer. However, there are some factors you should take into account before you part with your first deposit, no matter how tempted you are. Here are the key factors to consider. 

      FACTORDESCRIPTION
      🤑 Minimum depositThis is the minimum amount you’ll need to deposit in order to qualify for the 400% deposit bonus.
      💳 Payment methodsSome casinos restrict specific payment methods from 400 percent casino bonus offers.
      💸 Withdraw limitsGambling sites may  place a limit on the amount you can win with the bonus.
      📅 Time restrictionsAlmost all gambling offers have a limited timeframe, i.e., 7-14 days, or sometimes even 30.
      🎲 Game and stake restrictionsNot all games or stakes count equally towards wagering requirements, with slots contributing most and live games least. Play games that contribute more to pass the rollover requirements. 
      Wagering requirementsWagering requirements determine how many times you must play through the bonus before you withdraw any bonus winnings (e.g., 35x).

      Payment Methods Available at 400% Casino Sites

      To claim a casino bonus of 400%, you’ll need a casino with compatible payment methods. Most sites offer a broad selection of payment methods, but there’s never a guarantee that yours will be there. Always double-check!

      Generally, payment options vary in speed, fees, and minimum deposit limits, so it’s important to choose one that suits your preferences. Here are the most common ones. 

      Visa

      Toggle content

      Visa cards remain widely accepted, allowing straightforward deposits and wide accessibility. However, withdrawal times tend to be longer than with e-wallets.

      PayPal

      Toggle content

      PayPal is a trusted online payment option, providing secure and instant deposits and typically fast withdrawals (approx 48 hours). Getting bonus cash and free spins winnings is easy with this method.

      Apple Pay

      Toggle content

      Apple Pay allows mobile users to deposit quickly using their iOS devices without entering card details. However, it’s not accepted for withdrawals at all online casinos.

      Skrill

      Toggle content

      Skrill is a popular e-wallet for fast deposits and withdrawals, as it doesn’t show the casino your bank details. Read the online casino 400% welcome bonus terms carefully though, as Skrill deposits don’t always qualify.

      Pay by Mobile

      Toggle content

      As the name suggests, pay by mobile lets players deposit via their phone bill, making deposits quick and simple. 

      It’s not available for withdrawals, though. You'll need another payment method to withdraw winnings from online casino offers.

      Bank Transfer

      Toggle content

      Bank transfers are a traditional payment method. They’re reliable for larger sums but often take longer to process than e-wallets or cards (e.g., up to 5 working days).

      Casino Games to Play With a 400% Deposit Bonus

      400% deposit bonuses can be used on a variety of games, but sometimes there are game restrictions, and not all contribute equally to wagering requirements. 

      Here’s how the top casino game categories interact with this promotion.

      • Slots – Most slots count 100% towards the bonus wagering and offer fast-paced gameplay. Popular 400 deposit bonus slots include Starburst by NetEnt and Book of Dead by Play’n Go.
      • Table games – Computer-generated games like blackjack and roulette often contribute less to wagering and may have stake limits.
      • Live dealer games – Live dealer games typically have minimal contribution to wagering, though they provide an immersive experience. Look for dedicated live dealer bonuses if you want to focus on these games.
      • Bingo - Bingo often counts partially or minimally towards wagering requirements, if the site hosts bingo rooms. However, most casino bonus offers are for slots and lives.

      Best 400% Deposit Bonus Slots

      Slots are ideal for a 400% deposit bonus. Once you apply a valid bonus code, you get more bonus money to play a wide range of high-RTP games with exciting features, such as the following.
