SlimKing Bonuses

Our promotions cover both sides of the house: a four-part casino welcome pack, a separate sports offer, weekly cashback and two reload deals. Each offer has its own terms, and the casino welcome pack and the weekly reload cannot be combined with other bonuses. Promotions need a €20 qualifying deposit, while €10 is enough for a plain top-up.

Welcome Bonus

New customers can claim up to 350% and 500 free spins across the first four deposits, with spins credited in daily batches. The maximum stake while a casino bonus is active is €5, cash-out is capped at 3x the bonus, free spin funds transfer up to €50, and wagering runs for 10 days. Sports bettors can instead opt in at sign up for a 100% match up to €200, valid 21/04/2026 to 31/12/2026, with 30 days to wager and a €1,000 transfer cap.

Free spin funds from the casino pack also carry 30x wagering. Sports wagering must come from qualifying bets, which exclude cashed-out and voided bets, singles at odds below 1.90 and multi selections at odds of 1.51 or lower.

Cashback

Each week we return 15% of net losses as cashback, up to €3,000. The weekly cycle applies to casino play, and the figure is worked out from the losses left after wins across the same week, up to that €3,000 ceiling.

Reload Bonuses

The Weekly Reload Bonus applies to the first deposit made from Monday 00:00 to Thursday 23:59 UTC, worth up to 77% up to €700 plus 50 free spins. Wagering is 35x on deposit plus bonus and 35x on free spin funds, the stake cap is €5, cash-out is capped at 5x the bonus, and you have 3 days to wager while spins last 2 days. A Weekend Reload Bonus of 50% up to €700 plus 50 free spins covers the back half of the week. All registered players are eligible, and both offers may change at any time.

VIP Programme

Our VIP ladder runs across five tiers, unlocked through activity and loyalty. Benefits include on-site promotions, 24/7 live chat access, personalised offers, higher withdrawal limits, cashback and a personal VIP manager.

How to Claim Bonuses

1. Register a new account or log in to an existing one.
2. Opt in during registration, or open the My Bonus section of your profile.
3. Go to the cashier and pick a payment method.
4. Deposit at least €20 to qualify.
5. Activate the welcome bonus in My Bonus if it is not credited straight away; the Sport Welcome Bonus is selected during registration, and the weekly reload needs a fresh opt-in each week.
