📌 What is the Meaning of a 400% Casino Bonus?

Dice, cards, chips and money400% casino bonus is one of the best match deposit bonus, and like all other promotions in this category, it matches the deposit amount at a certain rate. You can find many deposit bonuses with different match rates in the market, and the most common rate is 100%. But sometimes, you can find bonuses that offer even more: a 400% first deposit bonus is a prime example. In its simplest form, this promotion gives a bonus of four times the deposit amount. For example, even a £10 deposit will give you a bonus balance of £40.

⚙️ Using a 400% Deposit Bonus: How does it Work?

This promotion actually has pretty simple mechanics and mostly works completely automatically. All you have to do to take advantage of a 400% first deposit bonus is make a deposit. This will have a minimum limit, which will be determined by the casino. As long as your initial deposit is at or above this limit, your bonus will be automatically credited to your account once the transaction is complete. (In some cases, you may also need to use a code.) This promotion is only offered to new members because the match rate is very high. Match deposit bonuses (aka reload promotions) available to existing members will have lower rates.

💡 What to Expect from a 400% Casino Bonus?

In order to find out what to expect from this promotion, you must learn its advantages and disadvantages. Because while it is highly advantageous, there are still some things you need to be aware of. The lists below will show you what the pros and cons of 400% deposit bonuses are.


  • You can win four times your deposit amount as a bonus.
  • You get a big boost in the beginning and turn a low budget into a big bankroll.
  • The bonus can be used on multiple games.
  • You almost always get dozens of free spins with it, too.
  • You can trigger the bonus even with a low deposit (i.e., 10 pounds).


  • The wagering rate can be higher than average.
  • The bonus itself cannot be used or withdrawn immediately: you need to complete wagering requirements first.

🔍 Finding a 400% Deposit Bonus in the UK

Truth be told, this is not a very common bonus. The match rates of deposit bonuses are usually in the range of 100% – 200%. A 400% deposit bonus is very rare and is almost always subject to a time limit. In other words, it should be used as soon as possible. If you do not have time to visit all top online casinos one by one and follow their promotions regularly, you can use the list we have prepared for you. Above you can see a list of the best online casinos that offer 400% deposit bonuses: we keep this list constantly updated.

🎁 The Difference Between a No Deposit Bonus and a Match Deposit Bonus

You can understand the difference between these two online casino bonus offers from their names. No deposit bonuses are automatically triggered upon completion of the signup process. In other words, you earn your bonus without making a deposit. A first deposit bonus, on the other hand, needs a deposit to be triggered, as the name suggests. No deposit promos seem more advantageous at first glance, but keep in mind that the cash or free spins you can earn with them will be very limited. Deposit bonuses, on the other hand, will allow you to earn much more.

🧾 Terms and Conditions of 400% Casino Bonuses

  • A deposit is always required to trigger this bonus. This deposit has a minimum limit, which may be higher than the casino’s general minimum deposit limit. For example, the casino may accept deposits of 10 Pounds, but a minimum of 20 Pounds may be required to trigger the bonus.
  • Note that you cannot use your bonus immediately. It will remain in a locked state until a certain amount of money has been wagered (this is called the wagering requirement). After this condition is fulfilled, it will become usable or withdrawable.
  • There will be some restrictions on your account until the wagering terms are met. For example, the maximum bet can be limited to 5 Pounds. Likewise, making a withdrawal can cancel the bonus.

🔮 Choosing the Best 400% Deposit Bonus: Tips and Tricks

  • The wagering rate determines the amount of money that must be wagered and should be as low as possible. Odds of 20x and below are ideal. For example, if your bonus is 200 Pounds and the wagering rate is 10x, you will only need to wager 2,000 Pounds.
  • You must play real money games to complete the wagering requirement, but the casino may have determined that only certain games will contribute to this requirement. For example, only your slot wagers will contribute 100%: in this case, playing other games will be just a waste of time. Pay attention to the game contribution rates.
  • Note that some casinos prohibit placing bets above the set maximum limit or using player-favouring tactics (for example, placing only red/black bets at roulette). Doing so may result in the bonus being cancelled automatically.
  • Note that the bonus may have a maximum cashout limit, and prefer offers that do not have such a limit. Maximum cashout means you will only be allowed to withdraw part of your bonus. So, for example, even if you win 1,000 Pounds, you will only be able to withdraw 500 Pounds.

🎰 Getting Free Spins with a 400% Deposit Bonus

Cards and slot machineIf you want to earn free spins in addition to your deposit bonus, this is certainly possible. Online casinos add free spins to many promotions. They can even be a stand-alone promotional item: no deposit free spins, for example, allow you to earn them just by creating a new account. However, welcome bonuses will almost always include a certain number of free spins and give you an additional boost.

Online casinos that offer a 400% deposit bonus also add free spins to them. You do not need to do anything special to claim them: as soon as you deposit, free spins will be credited to your account in addition to the cash bonus. In this way, it is possible to win 100, 200, or even more spins. Note, however, that these spins may be subject to different and separate wagering terms.

🌟 Other Deposit Match Bonuses You Should Know

A welcome bonus will always match your first deposit at a certain rate, and the match rate of the bonus mentioned in this guide is four hundred. But there are also deposit match bonuses with different rates, and some are more common. Below we share some of the most common examples of match deposit bonuses offered for online gambling:

💎 100% welcome bonus: The most common match bonus. The player’s first deposit is matched 1:1.

💎 200% welcome bonus: As can be seen from the rate, this promotion gives a bonus twice as much as the deposit amount.

💎 300% welcome bonus: With this promotion, you can get a bonus of up to three times your first deposit.

💎 500% welcome bonus: This is a rare promotion only offered to new players. It allows you to earn a bonus of up to five times the deposit amount.

Internet Slots FAQ’s

🍀 Can both new and existing members benefit from a 400% deposit bonus?

As a rule, both new and existing members can benefit from match bonuses. In practice, however, this bonus will only be offered to new members. The match rates of deposit bonuses offered to existing members of a casino will be lower (around 100% - 200%).

📱 Are 400% deposit bonuses available on mobile?

These bonuses can also be claimed from mobile devices, and even wagering conditions can be completed on mobile. Online casinos today are HTML5-based, so all the services they offer, including promotions, can run directly on web browsers. You can use a bonus from any mobile device, regardless of the operating system.

🎲 Can I use my 400% deposit bonus on any game at the casino?

This is a matter determined by the casino, but in general, the answer is yes. If it is not stated in the bonus conditions that it can only be used in certain games, you can use the balance you have obtained with the deposit bonus in any game you wish.

🤔 Can I claim a 400% welcome bonus more than once?

Welcome bonuses are designed for single use. Their aim is to encourage new members to make their first deposit. Once used, they are replaced by reload bonuses. You cannot benefit from more than one 400% welcome bonus at the same time. Likewise, you cannot activate a new bonus without completing the wagering requirements of another one.

🏅 Can I keep the prize I won with the 400% deposit bonus?

Yes, it is possible to keep the money you have earned with your bonus, but for this, you must first meet the wagering requirements. After a certain amount of money has been wagered, the winnings in your bonus balance will be transferred to your real balance and become withdrawable/usable.
