This limits the eligible initial deposit between $20 and $100, but the match percentage is still very high and rare. The wagering requirement is 40x your deposit and bonus amounts, which is slightly above the industry average, but the match value of the bonus makes up for it.

What Are 400% Bonus Casinos?

What Are 400% Bonus Casinos

A 400% deposit bonus casino is an online gambling platform that grants you this type of bonus. Most reputable online casinos present a deposit match reward in various forms, with or without extra spins. This bonus is suited for players who want to try out multiple games or use bigger betting sizes for their preferred ones.

Example of 400% bonus

If you deposit €10 at a 400 bonus online casino, you will get a bonus of €40 (€10 x 4) in return after you wager your initial 10 Euros deposit. So, instead of gambling with €10, you have €50. Some casinos may also reward you with extra spins as a welcome bonus, provided you meet the bonus requirements.

Most Searched 400% Casino Bonus Types

400% Casino Bonus Type Definition
Welcome Package A welcome bonus package is a generous offer from an online casino to its new users extending on more than one deposit. For example, you might have a welcome bonus of a 400% match deposit for a minimum of €10 for your first deposit and a match of 150% for the second deposit.
First Deposit Bonus The bonus you get for depositing your first sum on any casino site. Remember that you can get your 1st deposit and a no deposit bonus spins before that, if the casino offers both promotions.
Low Wagering Bonus  These offers help you achieve your turnover faster by decreasing the size of the total wagering. Low wagering means you reroll the sum under 25 times.
Deposit Match Bonuses Deposit match bonuses are casino promotions that match players’ deposits with bonus funds. To claim 400 per cent bonuses, you must deposit a minimum sum that triggers the mechanism.

Our Chief Editor at CasinoAlpha, Adina Minculescu, compiled the 400 percent bonus types above after carefully researching the popular bonuses across top online casinos.

The low wagering bonuses are popular among new and existing players since it’s one of the fastest and easiest ways to withdraw bonuses instantly. The first deposit bonus and welcome deposit bonuses are likewise popular among new players, as they often require a low deposit amount.

The important aspect you need to remember is that you can get any type of bonus if you open a casino account on trustworthy platforms with bonus codes.

How to Pick the Best 400 Casino Bonus

How to Pick the Best 400 Casino Bonus

You will find the best offers in a list of online casinos, but consider your province or residential country before making a choice. This is because the 400 bonus casino rules don’t apply equally to different players worldwide. For instance, a casino bonus 400% may restrict players from certain regions from placing a withdrawal with specific payment methods.

The list below are other factors or tricks that work in choosing the best deposit bonus offers.

  • Read the terms of the casino 400 deposit bonus. Ensure the wagering requirements, minimum deposit, and other rules guiding betting activities on the gambling platform are reasonable.
  • Check the maximum bonus amount. For every 400 casino bonus, there is a maximum amount of money you can cash out. Players can enjoy multiple games with the offer.
  • Compare the bonuses at different online casinos. It can be overwhelming choosing from a long list, but it is mandatory if you want the best deals.
  •  New online casinos might offer extra spins if you also download their app. So you might want to check that out.

How To Maximize Profit With 400% Casino Bonuses

How To Maximize Profit With 400% Casino Bonuses

As much as a casino bonus 400 is profitable, players can only make the most of it by betting strategically. This includes playing the right casino games, which mostly determines the wins you can get from casino promotions.

Choose games with high Return-to-Player (RTP), such as progressive slots. A game with high RTP means you will get a huge return on every amount you wager. A perfect example is the Mega Moolah slot, with an RTP of 94%. This means you will get €94 for winning €100 over a certain time. The higher a game’s RTP, the more profitable it is for you.

Another way to maximize bonuses with a 400 percent offer is to choose games with high wagering contributions, such as slots. Unfortunately, table games don’t often contribute to players’ wagering requirements as much as slots, which can contribute up to 100%.

However, if you want to play online live dealer games with a match deposit bonus, you should always read the bonus terms.

400% Casino Bonus Terms and Conditions to Be Aware Of

400% Casino Bonus Terms & Conditions Short Explanation
Games Contributions All games will not contribute equally to your wagering requirement. A slot game with a 100% wagering contribution means every money you wager on the game counts.
Wagering Requirements You won’t be able to withdraw if you don’t meet your bonus wagering requirements. It means you need to wager your bonus several times before withdrawing your winnings.
Time Limits Set timeframe in which you need to utilize your bonus. If you don’t meet up with the time, the bonus may be forfeited.
Bet Size Bet size is a range describing the minimum and maximum amount of bet you can place on a 400% casino bonus.
Maximum Cashout The most bonus money you can withdraw from a casino. Also, maximum cashout is usually time-bound – It can be daily, weekly, or monthly.
Payment Methods Casinos allow players to deposit and withdraw funds using various payment methods, including Bank Transfer, PayPal or crypto. However, not every casino allows players to use all payment methods on their deposit bonuses.
Eligibility Criteria Eligibility criteria are measures that casinos use to evaluate players and determine if they should use a bonus or not. These eligibility criteria include age, locality, and user experience.

At CasinoAlpha, we advise players to pay attention to bonus terms, which vary with different casinos. These terms tell you everything you need to know about a casino’s mode of operation. Most importantly, it will help you to determine if a 400% bonus casino is the right one for you or not. Also, you can always find bonus terms and conditions on the casino’s websites.

Fastest Payments in 400 Deposit Bonus Casinos

If you want to use some payment methods that are always accepted in casinos you can surely bet on debit or credit cards. These are always accepted in all casinos, even in crypto-based ones. However, their withdrawal time is longer, and some countries have penalties for using a credit card for gambling.

Another great payment used for bonus purposes is PayPal. The service is fast, secure and easy to use. You must open an account, link it, and deposit or withdraw the needed sums.

For easy deposits our specialists also recommend Paysafecard, Zimpler or Giropay. Depositing at 400% casinos is not hard, but you need to pay attention and play within your budget’s limits.
