Our Verdict on Foxy’s Offer

Our team believes this offer could be a hit among UK players looking to join Foxy Games. 400% deposit bonuses are rare in the UK, which makes this deal particularly enticing.

However, it’s important to consider the 40x wagering requirement tied to the bonus, which may seem steep for some players. It’s a trade-off common with such high deposit matches, typically better suited for those with some experience tackling bonus requirements. If you find higher wagering requirements intimidating, you could check out our selection of low wagering bonuses.

Nevertheless, if the cash bonus wagering feels overwhelming, the addition of no wagering free spins is something we appreciated.

Why Join Foxy Games?

We recommend Foxy Games to players who want flexibility with their payments. With a minimum deposit of just £5, and minimum withdrawals for just as low, it’s accessible to everyone. You have over 1200 games to choose from if you are looking for a diverse collection. Their round-the-clock live chat is also something we liked, as you can get help with account issues at any time.

However, there is no VIP program if you’re looking for existing player bonuses. Moreover, Foxy Games processes withdrawal requests in around 2 days, which we found to be slow. If this is a dealbreaker for you, check out our picks for fast payout casinos.

BetVictor’s Welcome Bonus – Best Alternative

If you’re eager to explore more 400% deposit bonuses like the one at Foxy Games, we think you should check out BetVictor’s welcome offer. With just a £10 deposit, you’ll instantly boost your balance with £50 in funds. While the wagering requirements remain at 40x the bonus amount, similarly to Foxy Games’ bonus, BetVictor’s offer doesn’t include any additional spins.

How We Review a 400 Percent Deposit Bonus Casinos in 2024

How We Review a 400 Percent Deposit Bonus Casinos in 2023

Want to know more about how we review casinos with 400% bonuses? We have simplified our criteria to help our subscribers understand our research methods. Vlad George Nita has gathered factual data to show you that we provide the best 400% casino bonuses.

We started from a list of 20 bonuses, and after testing each site, the selection was trimmed down to 4. Our experts check each site for at least 5 hours, aiming to meet the wagering and cashout.

Please take a look at our tools of expertise.

Minimum deposit offer and bonus value

British players must deposit a minimum amount to activate their 400% bonuses. We strive to select offers with the lowest possible minimum deposit. Yet, this value may differ from one casino to the next, ranging from £5 to £20.

Payment options

Most operators limit the types of payments you can use to claim a bonus to debit cards and one or two e-wallets. However, there should be some flexibility.

Wagering requirements

The appealing 400% first deposit welcome bonus percentage usually comes with high wagering requirements. However, we always prioritize the most convenient offers when researching 400% deposit bonuses in the UK.

Eligible games and bets

Our experts know which casino games you should play to clear out playthrough requirements faster. So, a vital part of our methodology is checking the bonus policy for eligible games. 400% first deposit bonuses that allow you to play many game types get extra points from our reviewers.

Cashout limit

Online casino play is not a source of income, but it’s a good idea to play with a goal in mind. Our experts analyze cashout limits for each 400% match bonus we recommend, anticipating a value of at least 5 times your initial deposit.

Bonus Availability

Besides every deep expertise regarding the deposit, cash out limit, et cetera, one key factor that helped us to make a clear view of the casino’s fairness is the casino welcome bonus, how generous the prize can be, and how the casino’s authority writes the bonus policy. If a casino doesn’t have a bonus available, in many cases, that casino is something that you don’t want to visit.

How We Test 400% Online Casino Bonus Offers

Without exception, our Best UK casino bonuses must pass a multi-step testing procedure. A closer view of our process will help you decide whether you should deposit and get a 400% bonus.

How We Test 400% Online Casino Bonus Offers

  • Research phase: Our team first gathers a list of operators that give out 1st deposit 400% bonuses. Then, the list is filtered only to feature legit United Kingdom casino operators.
  • Account creation and KYC: The first step of the actual review process is creating and verifying an account following the casino’s terms and conditions.
  • Real money deposit: When all prerequisites are met, we casino with a 400 the minimum eligible amount and activate the 400% bonus. This way, our testing phase mirrors the average British player’s experience.
  • Playing different casino games: With 400% bonuses, your bankroll multiplies 5 times so you can play quite a few games even with a low deposit. That’s what our experts do. We play the resulting balance in different games, noting the technical performance.

How to Choose the Best 400% Deposit Bonus For You?

How to Choose the Best 400% Deposit Bonus For You?

If you want to choose and try out a new online casino in the UK, first ensure it’s licensed.

Next, to determine if the 400% welcome bonus is the right fit for you, looking at the key terms and conditions when choosing one is important. Pay close attention to the wagering requirements, which specify how many times the bonus amount must be bet before winnings can be withdrawn. Also, remember to check the eligible games – some bonuses may exclude live dealer and table games.

Another thing you should keep an eye on is the maximum cashout limit, which caps the amount you can withdraw from the bonus wins. But this is not all. Other factors like the bonus validity period, minimum deposit, and eligible countries can also impact the value of the bonus and your possibility of using it.

Key Terms and Conditions of 400 Match Bonuses

Terms and conditions Explanation
Limited bonus value The value of a 400% bonus rarely goes over £100 in bonus funds, which may be lower than 300% or lower percentages.
Potentially high wagering requirement Since the deposit multiplier is so high, you can expect to wager the bonus 40 times or more
Excluded slots from bonus wagering Playing excluded games will lead to your bonus winnings being cancelled.
Low contribution to wagering in table games and video poker Table games may sometimes be excluded entirely from wagering, or they will contribute around 5 to 15%.
Limited contribution to wagering in live dealer games For most 400% casino bonuses, the bets you place in live games will only count around 2-10% of their value.
Excluded bets Some bets may cancel your bonus, for example, even money in roulette and doubling in slots.
Maximum bonus bet amount Generally, you should bet less than 10% or £5 to stay on the safe side. You can only keep what you win if your bets do not exceed this limit. A few UK casinos may have a £2.5/bet limit.
Restrictions on payment methods Debit cards are likely the only accepted form of payment. The most common restrictions are Skrill and Neteller, which cannot be used to claim promos at many casinos.
Maximum cashout limit Your final payout will be capped if you complete the wagering and win more than the limit.

The key to making the most of 400% deposit bonuses in the UK is to pay close attention to the fine print. Before diving in, we recommend you take the time to thoroughly review the terms and conditions of any offer, so you can grasp exactly how it works. Typically, you can find these details either below the bonus description or in the promotions section of the website.

After finding them, compare the wagering requirements, eligible games, maximum bet, and other rules across a few sites from the UK to see which offer best suits your playstyle and wishes.

Keep an eye out for any excluded slots that don’t contribute to the wagering requirement. Additionally, take note of any restrictions or reduced contribution rates for table games. Usually, the contribution for such game types is around 5 to 15%, which is not exactly lucrative.

Apart from game limitations, be mindful of factors like maximum cashout limits, minimum deposit requirements, casino bonus codes, and time constraints that may apply.

Understanding these terms upfront allows you to assess whether the 400% bonus suits your gaming style and budget before signing up. If you’re unsure about anything, we recommend you don’t hesitate to reach out to customer support for clarification.

400% Bonus for Table Games and Live Dealer Games

400% Bonus for Table Games and Live Dealer Games

UK players who prefer card games or roulette can play with their 400% deposit bonuses. Still, the wagering progress will be more challenging due to the limited game contributions.

The highest contributions for live games may reach 10%, and you’ll find them at the best live dealer casinos in the UK.

Live Dealer Casino Welcome Package Alternatives

Our experts have tested diverse live dealer casinos’ welcome offers in the UK industry to provide you with more quality casinos with different bonuses. All you have to do is visit those casinos and make your first deposit. The prizes are very generous, and you don’t need a promo code.

Best Top Live Dealer Casino Bonus Type Wagering Max. Withdrawal
Mr.Play Casino 200% up to £40 35x Not Mentioned
Voodoo Dreams 100% up to £50 30x £500 Casino 100% up to £50 + £6 live casino chips 40x £50 from chips

While these bonuses match your deposit by 400, some of the bonuses we recommended have a relatively high minimum deposit of £20. Play with a lower 10-pound minimum deposit amount on a live casino that’s equally good.

Alternative Casinos with Different Deposit Match

While 400% deposit bonuses have potential, they can also impose very high wagering requirements and limiting terms, which is where the best alternatives may become interesting for you. For many players, clearing a 400% bonus is unrealistic and takes away all the magic of the 400% deposit bonus.

Similarly, some inexperienced players may simply want to start with a smaller multiplier like the 300% bonus or 200% deposit offer or 100% deposit offers to test out a new casino and become more confident in their gambling skills.

Regardless, our KingCasinoBonus experts selected other casino bonuses with different deposit match percentages, so you can choose which one is the best for you.

  • 250% up to £35 at Kaiser Casino – Use bonus code “250” on your £10 first deposit to unlock the 250% match. While not the largest bonus, the reasonable 35x playthrough helps offset the lower cap. This bonus is worth claiming if you want to get both lower wagering and high match.
  • 200% up to £40 + Spins at Trada Casino – Enter “200UK” with your £20 deposit to claim a 200% bonus plus 100 Book of Dead spins. Despite high 60x wagering, the free spins available on one of the most popular slots in the UK add significant value. However, if you are not necessarily fond of Book of Dead and you want better terms for bonus funds, you should check out other 200% match bonuses.
  • 100% up to £200 at MadSlots Casino – This very common 100% match gives you 2x your deposit up to £200. With only 30x rollover, this bonus makes it easier to withdraw your funds. We recommend all beginners start out with this low wagering promotion, then move on to up to 500% match casino bonuses.

Final Verdict on the 400 Deposit Bonus Casino Sites

When reviewing 400% welcome bonuses, our experts take a meticulous approach to analyzing the terms and conditions. While the multiplier is always thrilling, the reality often reveals strict wagering requirements, game restrictions, and low withdrawal limits attached.

A typical 40-50x playthrough on just slot bets means clearing these bonuses requires a great deal of experience. Moreover, casual players may struggle to redeem winnings if you consider the low 5 to 10% table game and live dealer contributions. While bonus funds are typically meant to be used on a multitude of game types, the low wagering contributions on these game variations will clearly keep you from exploring them.

While possible, cashing out from a 400% match is statistically unlikely for the general player. Our advice is to target 100 to 250% offers boasting more favourable terms overall.


  • By claiming a 400% welcome bonus, you’re getting a large match to your initial deposit, increasing your balance significantly.
  • With extra bonus funds in your account, you can try out more games and gain a better understanding of the casino.
  • When redeeming deposit match bonuses, you’re not limited to just one game. You can use the 400% match to explore a variety of options and find the ones that suit your style best.


  • Meeting the 40 to 50x wagering requirements can be quite difficult, especially if you don’t have much experience with casino bonuses
  • In general, higher deposit matches have lower maximum cashouts. If your bonus winnings exceed the cap, you will only get the max cashout amount.
