What is a 400% bonus casino?
Online casinos use different bonus matches to attract players by allowing them to play with a better balance. Given the competitive nature of the gambling industry, casinos are forced to offer something extra; overall, it can be considered a marketing tool. In our article, we discuss the 400% deposit casino bonus, meaning that if you deposit £100, you will play with £500.
Is the 400% deposit bonus exclusive for new players?
No, existing players can get deposit deals with a 400% bonus match at the casinos on our list.
Is the 400% deposit bonus withdrawable?
Yes, you can request a withdrawal as soon as you clear the wagering requirements.
Advantages and Disadvantages of the Online Casino 400% Bonus
When playing video slots, it only takes one lucky spin to secure a massive win. It should come as no surprise that having access to more spins will dramatically increase your chances of achieving just that. Let’s check out other possible benefits of playing with a 400% casino bonus match.
Advantages
- You can play video slots with very high win potential, but infrequent winning spins. These video slots are generally referred to as high volatility and usually have very rewarding bonus rounds or special features. Immortal Romance from Microgaming and The Wish Master from NetEnt are prime examples of slots that rarely pay, but you can expect insane payouts when you get lucky.
- You have access to very high bets that can reward you massively when you get a full line of symbols. There’s nothing more infuriating than getting a full screen of the Explorer symbol in Book of Dead on the minimum bet.
- You get to play all the new games as soon as they are released. Having a large 400% bonus balance lets you take more risks and check out games you wouldn’t try otherwise.
Disadvantages
- Having to clear the wagering requirements has to be the only disadvantage. Playthrough requirements are much easier to clear if you can score a bonus with under x35 wager requirement. Anything above x35 requires some patience and time investment.

Bonus Terms and Conditions
The bonus terms and conditions will differ from casino to casino, and you must browse through them before playing. Remember that you will automatically receive a 400% bonus balance when you make a deposit. In some cases, the ongoing online casino bonuses will have separate terms that you can find on the “Promotions” page. Let’s find out what bonus conditions are the most important.
Wagering Requirements
Wagering, playthrough, or turnover requirements mean the same thing, and any of the forms could appear in the terms and conditions. The funds you deposit will be placed in a game balance, and you need to place bets until you have completed the wager.
How easy is it to wager the 400% deposit casino bonus?
Let’s assume you will make a £10 deposit with a 400% match welcome bonus. You will receive your initial £10 plus another £40 from the casino for a total balance of £50. Assuming that there is an x35 wager requirement, then it means that you need to place bets that total £1,750. The funds that remained after you wagered £1,750 will be moved to the real cash balance, and you can request a withdrawal.
Do all 400% match deposit bonuses have wagering requirements?
No, you can find a few casinos with no wagering requirements on our list. Be aware that there might be other active requirements like maximum allowed bet or maximum withdrawal limit.
Minimum Deposit Requirement to Receive Bonus
Online casinos with 400% bonus will usually have a minimum deposit required to qualify for the deal. The amount will fluctuate from casino to casino and might be different for each day of the week. We recommend that you visit the “Promotions” page to get updated information or by simply asking a support agent.
Playthrough Contribution Rates
Video slots have 100% contribution rates to the wagering requirements. There might be some exceptions to this rule for video slots with very high RTP percentages, 98%+. The terms and conditions page will have a detailed list of all casino game types and their contribution. Here’s an example:
- Slots – 100%
- Table games without Roulette – 10%
- Roulette – 20%
- Baccarat – 0%
- Video Poker – 10%
- Blackjack, Blackjack Surrender, Blackjack Switch, Great Blue, Santa Surprise – 0%
If you place £100 bets on Roulette in the above example, you will clear £20 from the playthrough requirements. If casinos did not implement turnover contribution rates, players would simply play Blackjack until they cleared the bonus.
Time Limits
Once you have received a bonus, there will be a limited time until you can clear the wagering requirements, one or two weeks in most cases. This aspect is critical when playing at an online casino with 400% deposit bonus because you will receive a considerable balance, so you will have to allocate time to gambling. If you do not clear the playthrough requirement within the allotted time frame, the casino will remove your initial deposit and bonus balance.
The 400 welcome bonus, as part of the Welcome Package, might come with a maximum number of days in which you have access to it. If you do not make a qualifying deposit within the required timeframe, the deal will become unavailable.
Max Bet Rule
You might be restricted to a maximum wager amount when playing with a bonus funds. The maximum bet rule has been introduced in recent years but can be found at more and more online casinos. Unfortunately, if you go above the maximum allowed, usually £5-15 per bet, you could lose your entire bonus balance. Another possible scenario can be that bets above the limit will not count towards playthrough requirements. Perform due diligence and check the terms as you do not accidentally want to break this rule.
Qualifying Banking Methods
The 400 deposit bonus casino might be restricted to specific deposit methods, for example, Bitcoin or Ethereum. Additionally, there could be deposit methods that do not qualify, most commonly debit cards or PayPal.
