How Cashback Works at Slimking

How Our Cashback-Style Coins Work

We return 5% of every deposit as Coins, worked out in GBP equivalent and added automatically as soon as the deposit clears — no claim form, no waiting period. Coins also build for every £100 wagered on casino games and every £100 placed and settled on sports bets, so the balance keeps moving whether we spin slots or place a bet across the sportsbook.

Coins sit in the account until we choose to spend them, and spending happens in the Store, where they convert into a casino bonus, bonus spins or a sports free bet depending on what we pick. There's no extra cashback claim form to submit — the Coins are simply available whenever we're ready to redeem them.

Turning Coins Into a Slimking Casino Bonus

Redeeming Coins for that reward means accepting a 40x wagering requirement, to be cleared within 10 days, with the amount we can release capped at 5x the bonus — a 10 GBP bonus, for example, releases a maximum of 50 GBP. That bonus only applies to the casino section, not live casino, sports or virtual sports.

Weekly Challenges and Extra Coin Rewards

Weekly Challenges reset every week and run automatically for every registered player who places a bet — there's no separate opt-in for either the Sports or Casino track. A sports challenge pays Coins equal to the bet amount divided by 10 once the bet settles as a win or a loss, each challenge carrying its own minimum bet, while a casino challenge pays a fixed amount of Coins that rises with difficulty.

Completing 20 challenges in a week in one section earns 50 extra Coins, and doing the same across both Sports and Casino adds up to 100 extra Coins in total. Top finishers in our in-house tournaments earn Coins as well, on top of whatever challenges pay out that week.

The same conditions that apply to any deposit bonus apply once Coins become bonus funds: only one bonus balance can be active at a time, real money in the account is wagered before bonus funds, and the maximum stake allowed while a casino bonus is active is 5 GBP per bet. If a withdrawal is requested before that wagering condition is met, the bonus balance and any derived winnings are voided.

Claiming a Store Reward Step by Step

Turning Coins into real play takes a few steps in the Store, and each reward type carries its own wagering window.

1. Open the Store from the account menu and check the Coins balance built up from deposits, wagering and Weekly Challenges.
2. Pick a reward — a casino bonus, bonus spins or a sports free bet — knowing only one bonus balance can be active at a time.
3. For bonus spins, activate them from the Profile section and use them within 7 days; winnings are credited as a bonus with a 40x wagering requirement to clear within 10 days.
4. For a free bet, place it as a single at odds between 1.51 and 5.50, with stakes up to 100 GBP and winnings capped at 450 GBP.
5. Activate the free bet within 24 hours of it being awarded and place it within 48 hours, since slots count 100% toward casino bonus wagering while table games, scratch cards and video poker count for 0%.
