Minimum deposits vary by payment method and remain at our discretion, though sports stakes start from just £0.50. Every deposit also earns 5% back as Coins redeemable in our Store.
Make Your First DepositWe don't publish one fixed minimum deposit figure — the amount accepted via Visa, Mastercard, bank transfer or e-wallet through our payment methods is set at our discretion and can differ by option. What stays fixed is what a deposit does once it lands: at Casino Slimking it is credited straight to your balance, with 5% of its value returned separately as Coins for our Store.
E-wallet deposits are processed almost immediately, so a small top-up is ready to play within moments. Visa and Mastercard payments, along with bank transfers, take longer because the transaction passes through your bank rather than through us directly. Whatever the method, once funds arrive you can stake from as little as 0.50 GBP on a single sports bet, so a modest deposit still covers several wagers.
If any part of your deposit is meant to trigger a bonus, you need to contact support before placing a single bet with it — the full conditions sit in our deposit bonus terms, and a bet placed first can mean the bonus is never credited retroactively, whatever the deposit size.
How fast a deposit reaches your balance depends entirely on the payment method you choose, since cards and bank transfers rely on outside processing that we don't control. E-wallets bypass most of that delay, which matters most when you're starting with a small amount and want to play straight away.
| Method | Deposit Speed |
|---|---|
| E-wallets | Lightning-fast, balance updates almost immediately |
| Visa | Slower, processed by your card-issuing bank |
| Mastercard | Slower, processed by your card-issuing bank |
| Bank transfer | Timing set by your own bank, not by us |
Picking an e-wallet is the quickest way to get a small deposit sitting in your account and ready to play, while a card or bank transfer deposit of the same size simply takes a little longer to clear before it reaches your balance.
A deposit only unlocks bonus terms if a short set of conditions is met before you start playing, regardless of how much you put in.
Visa, Mastercard, bank transfer and e-wallets are the four methods we support, and the minimum each accepts is left to our discretion rather than fixed in one published table. In practice the method decides how quickly that money is ready to play: e-wallet deposits land almost instantly, while card and bank transfer deposits depend on your own bank's processing time.
Once a deposit is in your balance, 5% of its value is automatically credited back as Coins, which can be exchanged in our Store for bonus spins or a bonus offer carrying a 40x wagering requirement, clearable within 10 days up to a release cap of 5x the bonus amount. A sports bettor working from a small balance can stake from as little as 0.50 GBP a bet, so even a modest first deposit covers several bets before it runs out.
Whatever the method you choose, the same account rule applies across the board: only one bonus may be active at once, and it must be claimed correctly — by contacting support before betting — for the deposit behind it to count toward the offer. For the complete picture of what we offer alongside deposits, see our casino overview.
We don't publish one fixed minimum deposit — the amount accepted for Visa, Mastercard, bank transfer and e-wallets is set at our discretion and can differ between methods. Once a deposit arrives, 5% of its value is automatically credited back as Coins, whatever the method used.
E-wallet deposits are lightning-fast and update your balance almost immediately. Visa, Mastercard and bank transfer deposits take longer because the transaction is processed by your bank before it reaches us.
Yes, but you must contact support before placing any bets with the deposit, otherwise the bonus may not be credited retroactively regardless of the amount deposited. Only one bonus can be active on your account at a time.
No, bonuses cannot be stacked and only one can be active per account, household, phone number or shared IP address at any time. A second deposit does not unlock a second simultaneous bonus.
The maximum stake allowed while a casino bonus is active is £5 per bet, no matter how large or small the original deposit was. Real money balance is wagered first, then the bonus balance.
Slots count 100% toward bonus wagering, Plinko and live casino excluding card games count 10%, while scratch cards, keno, table games and poker contribute 0%. Choosing the right game matters as much as the deposit size.
5% of every deposit is credited back as Coins, which can be redeemed in our Store for bonus spins or a bonus offer carrying its own 40x wagering requirement. That requirement must be cleared within 10 days, up to a release cap of 5x the bonus amount.
No, each method's minimum is set at our discretion rather than one shared published figure, though e-wallets are consistently the fastest to process. Card and bank transfer deposits depend on your own bank's timing.
