Slimking Bonuses, Free Spins And Wagering
SlimkingOur welcome package greets new players, and every bonus spin you unlock carries 40x wagering to clear within 10 days. We cap casino bonus bets at £5 and release up to five times the bonus amount.
Claim Your Welcome PackageYour Slimking Casino Bonus Explained
We welcome new players with a welcome package, and every casino bonus we hand out follows one clear set of rules: one active bonus at a time, 40x wagering on Store bonuses to clear within 10 days, and a £5 cap on every bet while a casino bonus is live. Here is how it all fits together.
How our wagering works
We always wager your real money balance first and only then your bonus balance. Store casino bonuses and the winnings from bonus spins both carry 40x wagering that must be completed within 10 days, and the most you can withdraw is five times the bonus amount — so a £10 bonus releases a maximum of £50. Slots contribute 100% toward wagering, which makes them the fastest way to clear a balance; you will find them all in our online casino.
Only one bonus can be active at any moment, and bonuses never stack on top of one another. If a bonus does not appear after your deposit, message our support team before you place a single bet, otherwise it may not be credited afterwards. Requesting a withdrawal before wagering is finished voids the bonus balance and any winnings tied to it, so clear the requirement first. Ready to begin? Open an account and your welcome package is waiting.

How Different Games Count Toward Wagering
Not every game pulls its weight when you are clearing a bonus, so it pays to know the contribution rates before you start. These percentages apply to all our casino bonuses, and the £5 maximum bet rule stands throughout. Because we wager real money before bonus funds, these rates only start to matter once you are playing with the bonus balance itself.
- Slots contribute 100%, except for the roughly 100 titles excluded from bonus play in our terms.
- Plinko and live casino games, excluding card games, each contribute 10%.
- Scratch cards and keno contribute 0% toward wagering.
- Table and card games, including poker and video poker, contribute 0%.
- Jackpot slots, Slingo, bingo and instant crash games cannot be played with bonus funds at all.
Stick to slots to clear a bonus quickly, check the excluded list before loading a favourite, and remember that staking more than £5 on any single bet can void the bonus entirely.
Free Spins, Free Bets And The Coin Store
Alongside casino bonuses, we run bonus spins, sports free bets and a Coin Store where rewards add up as you play. Bonus spins are activated in your Profile and must be used within 7 days; whatever you win arrives as bonus funds carrying the same 40x wagering to be cleared within 10 days.
Our sports free bets work to their own clock: activate within 24 hours of being awarded, then use within 48 hours. Single free bets run at odds from 1.51 to 5.50 with a maximum £100 stake and up to £450 in winnings, while single-or-multi free bets allow odds up to 10 and up to £900. Winnings are paid excluding the stake, so a £10 free bet at 3.00 returns £20, and free bets cannot be combined with Cash Out or Boosted Odds.
Every deposit also earns Coins worth 5% of the amount, with more Coins for each £100 you wager, and these can be exchanged for bonuses in the Store. One bonus applies per person, household, phone number and IP address, and players in Armenia, Tunisia, Bosnia and Herzegovina, Indonesia, Georgia and Malaysia are excluded from all promotions.

Bonus And Wagering Questions
What is the wagering requirement on a Slimking bonus? /
Our Store casino bonuses and bonus spin winnings both carry 40x wagering, which must be completed within 10 days. We wager your real money balance first and then the bonus, and the maximum you can withdraw is five times the bonus — a £10 bonus releases up to £50. Slots count 100% toward this requirement.
What is the maximum bet while a casino bonus is active? /
The maximum is £5 per bet, or the equivalent in your currency, whenever a casino bonus is active. Staking more than this can void the bonus and any winnings from it. Only one bonus can be active at a time, as bonuses cannot be stacked.
How do free bets work at Slimking? /
Activate a free bet within 24 hours of receiving it, then use it within 48 hours. Single free bets run at odds of 1.51 to 5.50 with a maximum £100 stake and up to £450 in winnings; single-or-multi free bets allow odds up to 10 and up to £900. Winnings are paid excluding the stake and cannot be combined with Cash Out or Boosted Odds.
Which games do not count toward bonus wagering? /
Table and card games, poker, video poker, scratch cards and keno all contribute 0%. Plinko and live casino games contribute 10%, while slots contribute the full 100%. Jackpot slots, Slingo, bingo and instant crash games cannot be played with bonus funds at all.
