How Payments Work at SLIMKING
Last updated: August 19, 2026
SLIMKING supports a mix of card, bank and cryptocurrency payments so UK players can pick what suits them. This page explains what's on offer and where to check the exact numbers that apply to your account.
Payment methods we support
We keep the payment menu focused rather than cluttered. Every method listed below is available in the cashier once you're logged in, and each one shows its own minimum, maximum and processing details before you confirm a transaction.
- Visa: debit card deposits, the most common route for UK players
- Mastercard: debit card deposits, same-day in most cases
- Bitcoin: for players who prefer to move funds without a bank in the loop
- Ethereum: a second major cryptocurrency option
- Tether (USDT): a stablecoin option for players who want to avoid crypto price swings between deposit and withdrawal
- Litecoin: typically faster confirmation times than Bitcoin
- Bank Transfer: a direct transfer from your UK bank account
Making a deposit
To deposit, open the cashier from your account menu, choose a method, and enter the amount. Card deposits usually land in your balance within moments. Bank transfers can take a little longer depending on your bank's own processing schedule. Crypto deposits are credited once the transaction receives the required number of network confirmations, which varies by coin.
Minimum and maximum deposit amounts differ by method and can change over time, so we don't quote fixed figures here. The cashier always displays the current limit for whichever method you've selected, before you commit to the transaction.
Withdrawals and processing times
Withdrawal requests go through account verification first. This is standard practice across UK-facing casinos and it protects both you and us. Once verification is complete, processing times depend on the method: card and bank withdrawals generally take longer to clear than crypto withdrawals, which move on the relevant blockchain once approved on our side.
Limits can change with your account status
Some limits are tied to how far along you are in account verification. A newly registered account may see lower withdrawal limits than one that has completed full ID checks. If you're planning a larger withdrawal, it's worth confirming your verification status in advance so it doesn't hold up the payout.
| Group | Methods | Typical use |
|---|---|---|
| Cards | Visa, Mastercard | Fast deposits, familiar for most UK players |
| Bank | Bank Transfer | Direct from a UK current account |
| Crypto | Bitcoin, Ethereum, Tether (USDT), Litecoin | For players who prefer digital assets |
Your balance is always shown in GBP
Whichever method you deposit with, your account balance, bet amounts and any winnings display in pounds sterling. If you deposit with cryptocurrency, the value is converted to GBP at the point of crediting, and that converted figure is what you'll see and play with. This keeps your bankroll easy to track regardless of how you fund it.
Keeping payments part of a controlled routine
The cashier also lets you set your own deposit limits if you want a personal ceiling that's lower than the account maximum. That's worth doing early rather than after a session, since it's a tool for planning ahead rather than a fix for the moment. If you'd like support around your play more generally, GamCare (0808 8020 133, https://www.gamcare.org.uk/) and BeGambleAware (https://www.begambleaware.org/) are both free to contact. SLIMKING is for players aged 18 and over only.

Verifying your account
Before your first withdrawal we may ask for proof of identity and proof of address. This is standard practice across regulated UK operators and it protects your funds from being accessed by anyone else. Uploading clear documents the first time you're asked speeds things up considerably.
If a payment fails
Card declines and failed bank transfers usually come from your provider's own fraud checks rather than anything on our end. Try a second method or contact your bank before raising a support ticket. If a deposit is taken but doesn't reach your balance within a few minutes, get in touch with the details and we'll trace it.
All transactions run over encrypted connections, and we never store full card numbers on our own systems.

Visa, Mastercard, Bank Transfer, and the cryptocurrencies Bitcoin, Ethereum, Tether (USDT) and Litecoin. All are available directly from your cashier once you're logged in.
Why can't I see exact deposit and withdrawal limits on this page?
Limits vary by method and can depend on your account's verification level, so they're shown live in the cashier rather than fixed here. Always check the cashier before making a transaction.
Will my balance show in a cryptocurrency or in pounds?
Your balance always displays in GBP. Crypto deposits are converted to GBP at the point they're credited to your account.

It depends on the method and on completing account verification first. Card and bank withdrawals typically take longer to clear than crypto withdrawals. The cashier shows current estimated times for each method.
Can I set my own deposit limit?
