Two Deposits, Two Matches, One Clear Starting Point

Welcome to our official Slimking website. Our opening package is Up to £1,200 + 250 FS, divided between your first two qualifying deposits. Both stages match your deposit at 100%, but their bonus caps and spin awards differ. We explain those differences here so you can judge the offer against the amount you actually intended to spend.

Read the package as two parts

The first offer is Up to £1,000 + 200 FS; the second is Up to £200 + 50 FS. Both match at 100%. A deposit must be at least £20 to qualify. The overall headline describes the maximum across both stages; it is not the amount added to every account.

A deposit below a stage's cap earns an equal amount in matched bonus funds. Depositing above the cap cannot increase your match.

Keep three amounts separate

Distinguish what you pay in, what we add as a bonus and what you need to wager. Bonus funds carry a 35x requirement. Free-spin winnings also become bonus funds under 35x. An opening balance therefore does not tell you how much you can withdraw.

Decide whether the terms fit

Our casino is for adults aged 18 or over. Set an affordable deposit budget, consider the wagering and read our licence disclosures before registering. You can leave an offer alone if its conditions do not suit you.

Your First Match: Start With the Deposit You Planned

The first stage is a 100% deposit match, with an offer of Up to £1,000 + 200 FS. The minimum qualifying payment is £20. At this stage, the cash bonus follows your deposit pound for pound until the £1,000 cap is reached.

Follow an £80 deposit through

Suppose you choose an £80 qualifying first deposit. We add £80 in matched bonus funds. Your own £80 and the £80 match give £160 before any game results or spin winnings.

For the £80 bonus, the wagering amount is £2,800 (35 times £80). That figure describes required turnover, not an extra deposit and not a promised withdrawal. Winning or losing during play changes the balance available to continue.

First-stage example Amount
Your qualifying deposit £80
Our 100% match £80
Deposit and match together £160
Wagering on that match £2,800

Understand the upper boundary

A £1,100 first deposit reaches the £1,000 match cap. It does not earn a £1,100 bonus. The deposit and capped match total £2,100 before play; the match's wagering is £35,000 (35 times £1,000). This illustrates a ceiling, not a recommended deposit.

Increasing the match also increases the turnover required. The cap is a promotional limit, not a spending target.

Leave the spins outside this calculation

The stage includes 200 free spins, but their eventual winnings are unknown. We therefore do not add an assumed spin value to either example. If the spins return winnings, those funds bring their own 35x calculation. Read the spin conditions before deciding what the full stage involves.

The Second Match Has a Smaller Ceiling

Our second qualifying deposit offer is Up to £200 + 50 FS. We still match 100%, and the qualifying minimum remains £20. The change is the cap: the second cash match stops at £200 rather than the first stage's £1,000.

Work through a £140 payment

For a qualifying second deposit of £140, your matched bonus is £140. Together, those amounts make £280 before play. Wagering on the match is £4,900 (35 times £140). This calculation excludes anything won from the 50 free spins because their results cannot be predicted.

Keep the wagering figure beside the starting amount: £280 available before play differs from £4,900 in turnover.

See what happens above the cap

If a second qualifying deposit is £240, the bonus remains £200. Your deposit and match total £440 before any results, with £7,000 (35 times £200) in wagering on the matched funds. The extra £40 deposited above the ceiling does not earn another £40 of bonus.

Second-stage example Matched bonus Wagering on match
£140 deposit £140 £4,900
£240 deposit £200 £7,000

Put the two stages beside your budget

Using the £80 first-deposit example and the £140 second-deposit example means £220 paid in and £220 in matched funds overall. Their match-related wagering amounts total £7,700. Those are illustrative totals across separate stages, before spin winnings, rather than a single combined account balance.

You do not need to make the second payment just because you have made the first. Reconsider your budget and the conditions before any further deposit. A welcome headline should never decide your spending for you.

Beyond the Welcome: Different Offers Need Different Decisions

We also offer returning-player promotions. Treat our weekend reload, weekly cashback and tournaments as separate offers from the welcome.

A weekend percentage

The reload adds 50% under its promotion rules. Before taking it, ask about the applicable cap, wagering and eligibility. We give no cap or wagering figure for this offer here, so you should not assume the welcome's 35x condition also explains the reload.

Cashback calculated after losses

Our cashback is 10% of net losses and is credited weekly. The cashback itself has no wagering requirement. For an illustrative £120 net loss, the return is £12. That leaves a cost of £108 after the return; it does not turn the week's losses into a profit.

Keep cashback out of the money you count on for bills or a future deposit. It is a partial return calculated from losses, so trying to earn more of it means risking more first.

Events and activity-based benefits

We have slot, live and sports tournaments with prize pools from £250 to £2,500. Review the event rules before taking part rather than treating the prize pool as your own potential balance.

Our VIP club advances according to activity. Higher levels bring personalised offers, faster withdrawals, increased withdrawal limits and a dedicated account manager. Choose your playing budget independently of those benefits. We do not give tier names, a tier count or a universal withdrawal limit on this page.

Turn 35x Into a Number You Can Understand

For our welcome matches, 35x applies to the bonus amount. It does not mean multiplying the deposit and match together. Required wagering is turnover through play; it is neither a guarantee that funds will survive that play nor a promise of winnings.

Use the bonus as the starting number

Return to the first-stage £80 example. The matched bonus is £80, so the calculation gives £2,800 (35 times £80). Calculating from the £160 deposit-and-match total would use the wrong starting amount. Similarly, the second-stage £140 match produces £4,900 (35 times £140), not a requirement based on £280.

These examples explain the multiplication. Establish how a game's wagers contribute before playing with bonus funds; lobby inclusion does not establish eligibility.

Account for free-spin winnings separately

Our spin awards are counts of spins, not guaranteed cash amounts. Any winnings they produce arrive as bonus funds under the same 35x rule. If an illustrative spin result gives £12 in bonus winnings, those funds carry £420 (35 times £12) in wagering. An actual spin result may be different.

The two spin awards total 250, but we assign no predicted cash return to that count.

Respect the maximum stake condition

A maximum stake per spin applies during bonus wagering. Ask for the applicable amount before playing: we do not print a number that our offer summary cannot support. A game's normal stake options should not be taken as permission to exceed the bonus condition.

Read the headline alongside the work involved

The complete welcome is Up to £1,200 + 250 FS. At the two cash-match caps, wagering on the first match is £35,000 and on the second is £7,000. Together that is £42,000 in match-related turnover, with any spin-winnings requirements additional.

Those large numbers are a useful reason to pause. They do not suggest that you should make deposits up to the caps. A smaller qualifying match brings a smaller wagering amount, though it still carries conditions and the risk of losing your deposited money.

Ask before you accept

Check the activation instructions, permitted games, contribution rules and any time conditions with the offer. We do not specify deadlines or contribution percentages here. If anything remains unclear, speak to our team before depositing. You should understand a bonus well enough to decide against it, as well as to accept it.

Browse Our Games Without Guessing Bonus Eligibility

We offer 5,000+ games across slots, tables, live casino, game shows, crash and instant titles, plus a sportsbook. The range gives you options; it does not mean every option has identical promotional conditions.

Reels and table choices

The slot selection includes Megaways, bonus-buy and jackpot categories. Named titles include Gates of Olympus, Big Bass Bonanza, Starburst, Book of Dead and Wanted Dead or a Wild. Our studios include Pragmatic Play, Hacksaw Gaming, NetEnt, Play'n GO, BGaming, Nolimit City, Betsoft, Booming Games and Red Tiger.

For table play, we have blackjack, roulette, baccarat and poker variants. Choose a format you understand, then read its rules. Avoid judging a game by how quickly you hope it will complete a wagering requirement.

Dealers, presenters and quick rounds

Evolution is among our studios. Lightning Roulette, Crazy Time and Dream Catcher are named options, while Aviator appears among crash and instant games. Decide your playing time before choosing a format.

Sporting selections

We cover pre-match and in-play betting, with singles and combinations. Sports include football, tennis, ice hockey, basketball and rugby; esports include Counter-Strike and Dota 2. Using the same account is convenient, but it is still your money at risk when you switch from casino to sport.

Ask about the game, not just the category

If you plan to use welcome funds, ask whether your particular game is eligible and what contribution applies. We do not promise that a whole category qualifies. Choose entertainment within your budget instead of chasing a faster route through the bonus.

  • Pragmatic Play
  • NetEnt
  • Big Time Gaming
  • Relax Gaming
  • Push Gaming
  • ELK Studios
  • Nolimit City
  • Blueprint Gaming

Open an Account With Accurate Details

We accept adults aged 18 or over, with a single account allowed per person. Registration asks for an e-mail address, password, name, date of birth, address and phone number. Complete the e-mail confirmation link after entering those details.

Think ahead to verification

Use information that agrees with your documents. Before the first withdrawal, we check your identity, address and payment method. Entering correct details from the start avoids a mismatch you could have prevented.

Choose limits before a deposit

Decide how much you can afford to lose before considering either welcome stage. Deposit limits and session reminders are available, alongside cooling-off and self-exclusion. A bonus cap is our promotional ceiling; your personal spending limit should come from your own circumstances.

Keep access private

Choose a password you do not share with other people. Contact our English-speaking support team if you need account guidance.

Separate Verification Time From Payout Time

We accept deposits from £20 without charging deposit fees. Listed methods are Visa, Mastercard, Skrill, Neteller, Paysafecard, bank transfer, Bitcoin, Ethereum, Tether and Litecoin. Paysafecard can fund a deposit but cannot receive a withdrawal.

Documents before your first payout

We verify ID, proof of address and the payment method before the first withdrawal. Checks usually take 24–48 hours. Prepare the relevant information and ask our team what is required if you are unsure. Do not assume that completing bonus wagering also completes identity verification.

Count processing from approval

Withdrawal route Processing after approval
E-wallets and crypto 0–24 hours
Cards 1–5 working days
Bank transfer 3–7 working days

These windows begin after approval. They should not be read as a single countdown starting from the moment you register or request a withdrawal. Verification and the payment method are separate parts of understanding the timing.

Read your own withdrawal conditions

VIP progression brings higher withdrawal limits, but we do not state a fixed maximum. Ask what applies to your account before planning around a particular amount. If bonus funds are involved, establish the relevant promotion conditions too.

Keep the method and date of your request available when asking for help. Our team can address a specific payment question more clearly when you describe the transaction rather than only the balance you expected.

  • Visa
  • Mastercard
  • Skrill
  • Neteller
  • Paysafecard
  • Bitcoin
  • Ethereum
  • Litecoin

Keep the Offer Readable on Your Phone

You can play through a mobile browser on iOS or Android. We have no native app, and no download is needed. If you add a home-screen shortcut, it opens our website through your browser.

Pause at the numbers

Read the payment, match and wagering separately. A £140 second-stage payment and £140 match differ from the £4,900 turnover requirement. Do not make a payment while only the headline is in view.

Give the session an end

Choose a stopping time before opening a game and use a session reminder. A phone makes the site easy to reach, so keep that convenience within the time you meant to spend. You can take a cooling-off break rather than returning whenever there is a spare moment.

Protect your device

Keep your password private and avoid leaving an account accessible on a shared phone. If you need help understanding an offer while browsing, our English live chat operates 24/7.

Know Who Operates Slimking and Which Exclusions Apply

Our operator is 3-102-945295 SRL, registered in Costa Rica. Slimking's licence is from the Costa Rica Gambling Authority. We are not licensed by the UK Gambling Commission and are not part of GAMSTOP. Consider both disclosures before choosing an account.

GAMSTOP does not cover us

An exclusion through GAMSTOP does not extend to Slimking. If you use GAMSTOP to stay away from gambling, do not register here as an alternative. Gamban is blocking software to consider for restricting gambling access on your devices.

Choose the restriction you need

We provide deposit limits, session reminders, cooling-off and self-exclusion. Use a deposit limit to support your spending plan and a reminder to bring time back into view. If continuing to play is causing harm, consider exclusion rather than adjusting the size of the next deposit.

Speak beyond the casino

For UK help, contact GamCare's National Gambling Helpline on 0808 8020 133. Reaching out is a reasonable step before losses or worry grow. Gambling should remain entertainment you can afford; neither a bonus nor cashback makes it a solution to financial pressure.

Ask Us to Explain the Condition That Matters

Our live chat is available 24/7 in English, and e-mail support is also offered. You can ask about the welcome stages, verification, payment timings or safer gambling tools.

Make a bonus question specific

Tell us whether you mean the first match, second match or weekend reload. Give the proposed deposit and the rule you want explained, such as the wagering on a £140 second-stage match.

Leave sensitive details out

Do not include a password or complete card number in a general support message. For a payment question, keep the date, method and transaction reference to hand. For verification, ask which document or detail you need to provide.

Stop before an unclear payment

If you cannot explain the wagering, permitted stake or qualifying game, wait before depositing. You can also ask about a break or self-exclusion. A conversation about account controls does not need to begin with another offer.

Weigh the Match Against Its Conditions

Our welcome gives you two separately capped matches: Up to £1,200 + 250 FS overall. The first cash cap is £1,000, the second £200, and New Player Bonus funds carry 35x wagering. Read the examples, consider our Costa Rica licence and GAMSTOP status, and choose a spending limit before deciding whether to join.

What We Make Available

  • A 100% match on each of the two welcome deposits
  • 200 first-stage spins and 50 at the second stage
  • Weekly 10% net-loss cashback without cashback wagering
  • Deposit limits, session reminders, cooling-off and self-exclusion
  • English live chat available 24/7

Conditions That Need Your Attention

  • Costa Rica licensing; no UK Gambling Commission licence
  • GAMSTOP exclusions do not extend to our casino
  • New Player Bonuses and spin winnings need 35x wagering
  • Paysafecard supports deposits without withdrawals

FAQ

Does the headline describe my first deposit alone?

No. Up to £1,200 + 250 FS is the combined welcome maximum. The first stage offers Up to £1,000 + 200 FS, and the second offers Up to £200 + 50 FS. Your cash match depends on the qualifying deposit and its stage cap.

How does an £80 opening deposit add up?

A qualifying £80 first payment earns an £80 match, giving £160 before play or spin results. Wagering on the match is £2,800 (35 times £80). The first stage also includes 200 free spins; their winnings are not predicted in that calculation.

What changes if my second deposit is £240?

We cap that match at £200. Together with your £240 deposit, that gives £440 before play. The wagering required for this capped match is £7,000 (35 times £200), with any free-spin winnings considered separately.

Which amount do I multiply for welcome wagering?

Use the bonus amount, rather than your deposit-and-match total. Our factor is 35x. For a £140 second-stage match, that is £4,900 (35 times £140). Ask how your selected game contributes before starting.

Can I count free spins as guaranteed cash?

No. We award 200 spins at the first stage and 50 at the second, without predicting their results. Any winnings arrive as bonus funds and carry 35x wagering. An illustrative £12 result therefore has £420 in wagering.

What is the smallest qualifying payment?

£20 for a welcome-stage deposit. Set your own affordable limit first. Do not increase a payment simply because a larger match is advertised.

Is weekend reload wagering also stated here?

We confirm a 50% weekend reload but give no reload wagering figure or cap. Request the applicable conditions before choosing it; the welcome calculations do not establish the reload rules.

When does the e-wallet payout window begin?

After approval: e-wallets and crypto take 0–24 hours. Cards take 1–5 working days and bank transfer 3–7 working days. First-withdrawal verification usually takes 24–48 hours and is a separate check.

Must I install anything to play on Android?

No installation is needed. Use your mobile browser on Android or iOS. A home-screen shortcut is optional and opens the browser website; we have no native app.

Who can help me take a break from gambling?

Ask us about cooling-off or self-exclusion. GamCare also runs the National Gambling Helpline on 0808 8020 133. Slimking is outside GAMSTOP, so its exclusions do not cover us; consider Gamban for device blocking.
