What Is a 400% Deposit Bonus?

Why Are These Bonuses Rare?
While a 400% deposit bonus is attractive, it’s less common than more standard offers like 100%, 200%, or 300%. This is due to the higher risk for playhouses, as they need to account for the larger payouts, which can affect profitability.

Claiming a 400% deposit bonus is simple, but it’s important to follow the correct steps to meet all requirements. Here’s a quick guide to help you maximize your promotion.
Step 1: Choose a Reputable Casino with a 400% Deposit Bonus
Select a trusted playhouse offering a 400% deposit bonus. Look for licensing (e.g., UK Gambling Commission), read reviews, and ensure secure payment options. Consider top 400% deposit bonus casinos like Casumo, Betway, or LeoVegas.
Step 2: Register and Verify Your Account
Create your account by:
- Providing personal details (name, email, address)
- Setting a secure password
- Verifying your identity (e.g., passport, utility bill)
This ensures you’re legally eligible to gamble, especially in the UK.
Step 3: Make a Qualifying Deposit
To claim the 400% first deposit bonus:

- Check the promotion maximum deposit limit
- Use an eligible payment method (some options like Skrill/Neteller may be excluded)
Step 4: Enter the Bonus Code (If Required)

By following these steps, you’ll easily claim and maximize your 400% deposit bonus. Always review the bonus terms before playing.
Types of 400% Casino Bonuses

- Third Deposit: 100% up to £100
It offers great value and extended playtime, ideal for exploring various games.

3. 400% Reload Bonus

Each type of 400% deposit bonus is tailored to different players, so always check the bonus structure and wagering requirements to find the best deal.
Wagering Requirements Explained (With Examples)
When claiming a 400% deposit bonus, understanding wagering requirements is crucial. These are the conditions you must meet before withdrawing your bonus funds or winnings.
What Are Wagering Requirements?
Wagering requirements refer to how much you need to bet before you can withdraw any bonus funds. For example, with a £400 bonus and a 40x requirement, you must wager the promotion amount 40 times.
Example:
- Deposit: £100
- Bonus: £400 (400% bonus)
- Total Balance: £500
- Wagering Requirement: 40 x £400 = £16,000 total playthrough needed.
This means you need to wager £16,000 in qualifying bets before withdrawing winnings.
Low vs. High Wagering Requirements
- 40x wagering is considered fair, especially for a 400% deposit bonus. Higher requirements (e.g., 50x) make it harder to clear promotion.
Example of High Wagering:
- Bonus: £400
- Wagering: 50x
- Playthrough: £20,000 needed to release funds.
Best Practice: Look for Bonuses with ≤40x Wagering
Look for 400% deposit promotions with wagering requirements of 40x or less for easier promotion clearance.
Check If Table Games/Live Casino Contribute
Not all games contribute equally to wagering. For instance:
- Slots: 100%
- Table Games: 20%
- Live Casino: 10%
Always check how different games contribute to the wagering requirements in the promotion terms.
Key Takeaways:
- Wagering requirements determine how much you must bet to withdraw winnings.
- Ideally, look for 400% deposit bonuses with wagering ≤40x.
- Games contribute differently to wagering—slots often count 100%, while table and live casino games contribute less.
Pros and Cons of 400% Deposit Bonuses
- Massive Bankroll Boost: A 400% deposit bonus can quadruple your deposit, giving you a larger bankroll to play with.
- Extended Playtime: More promotion funds mean more time to explore different games and increase your chances of winning.
- Extra Free Spins: Some playhouses offer free spins in addition to the bonus, enhancing your chances of winning without extra cost.
- Great for All Players: Both new and experienced players can benefit from a larger balance, allowing for longer sessions and more game variety.
- High Wagering Requirements: 400% deposit promotions often come with high wagering (40x-50x), making it harder to withdraw winnings.
- Game & Payment Restrictions: Some games and payment methods may not qualify for the promotion or contribute to wagering requirements.
- Max Cashout Limits: There may be a cap on how much you can withdraw from the bonus, limiting potential winnings.
- Expiry Dates: Many promotions have short validity periods, requiring you to meet wagering conditions within 7-14 days.
400% Deposit Bonus vs. Other Casino Bonuses
When choosing a playhouse promotion, it’s essential to compare the 400% deposit bonus with other common promotion types to determine which one suits your preferences and playstyle. Here’s a quick comparison:
| Bonus Type | Bonus % | Typical Wagering | Best For |
| 400% Bonus | 400% | 35x-50x | Big bankroll boost |
| No Deposit Bonus | £10-£20 | 40x-50x | Low-risk tryout |
| 100% Bonus | 100% | 20x-35x | Standard match bonus |
| 200% Bonus | 200% | 25x-40x | Mid-range bonus seekers |
| 500% Bonus | 500% | 50x+ | Rare, high-wagering offers |
Key Differences:
- 400% Bonus: A 400% deposit bonus is excellent for players who want a massive boost to their bankroll but be aware of the wagering requirements (35x-50x).
- No Deposit Bonus: Offers a smaller amount (usually £10-£20) but with similar high wagering requirements. It’s a low-risk way to try a playhouse without a deposit.
- 100% Bonus: Commonly offered as a standard match promotion, with lower wagering (20x-35x). It’s perfect for players who want a balanced offer.
- 200% Bonus: A middle ground between the 100% and 400% bonuses, offering a good value with moderate wagering.
- 500% Bonus: While this may seem like a great deal, it usually comes with high wagering requirements (50x+), making it harder to benefit from promotion.
Conclusion
The 400% deposit bonus is ideal for players who want a large promotion and are willing to deal with higher wagering requirements. If you prefer lower requirements or a smaller risk, other promotions like the 100% match or no deposit bonus might be more appealing.
Best Games to Play With a 400% Bonus
To clear the wagering requirements efficiently with a 400% deposit bonus, focus on games that contribute the most.
1. Slots: 100% Contribution
Slots contribute 100% toward wagering, making them the best choice for clearing your 400% deposit bonus. Look for high-RTP slots like:
- Starburst (NetEnt)
- Gonzo’s Quest (NetEnt)
- Reactoonz (Play’n GO)
2. Table Games: 10%-20% Contribution

3. Live Casino Games: 10%-20% Contribution
Live dealer games also contribute 10%-20%. Though immersive, they take longer to clear the 400% deposit bonus compared to slots.
Key Takeaways:
- Slots are the best for quickly clearing the 400% deposit bonus (100% contribution).
- Table games and live casino games contribute less (10%-20%), so expect slower progress.
How to Maximize Your 400% Bonus (Pro Tips)
Claiming a 400% deposit bonus can be an exciting way to boost your bankroll, but to make the most of it, you’ll need to approach it strategically. Here are some pro tips to help you maximize your promotion and meet the wagering requirements more efficiently.
1. Choose Low-Wagering Offers (≤40x for Best Value)
Always look for 400% deposit bonuses with the lowest wagering requirements. Ideally, choose offers with ≤40x wagering, as they are more manageable. The lower the wagering requirement, the easier it will be to turn your benefit into real money.
2. Play High-RTP Slots (Above 96% RTP)
To increase your chances of winning and clearing the benefit, focus on high-RTP slots. Slots with an RTP (Return to Player) of 96% or higher give you better odds over time. Examples of popular high-RTP slots include:
- Starburst (NetEnt)
- Gonzo’s Quest (NetEnt)
These slots not only help clear the bonus quickly but also give you a better chance of landing big wins.
3. Check Time Limits
Most 400% deposit promotions come with an expiry date. Make sure you understand the validity period before claiming the benefit. For instance, you may have 7-14 days to meet the wagering requirements. Set reminders so you don’t miss out on the opportunity.
4. Avoid Restricted Payment Methods
Certain payment methods, like Skrill and Neteller, may not qualify for the benefit or might restrict your ability to meet the wagering requirements. Always check the terms to ensure that your deposit method is eligible for the benefit.
5. Stick to Max Bet Limits
Many playhouses set a maximum bet limit when using a bonus. If you exceed the limit, you risk forfeiting your bonus. Stick to the bet limit to avoid complications and ensure your benefit remains valid throughout the wagering process.
Key Takeaways:
- Choose bonuses with ≤40x wagering for easier clearing.
- Play high-RTP slots for better chances of winning.
- Always check expiry dates, payment restrictions, and bet limits to avoid any surprises.
