SlimKing Bonuses

We run separate reward tracks for casino and sports play, topped by a four-deposit welcome pack and backed by weekly cashback and reloads. Welcome offers are opted into during registration or from the My Bonus section after depositing, and the weekly reload needs a fresh opt-in each week.

Casino Welcome Pack

The casino welcome offer spreads 350% up to €10,000 and 500 free spins across your first four deposits, with a minimum of €20 each time. Free spins arrive in daily batches, wagering runs at 30x on deposit plus bonus and 30x on free spin winnings, and the max bet while wagering is €5. Cash-out is capped at 3x the bonus amount, free spin winnings transfer up to €50, and you have 10 days to clear the play-through. It is open to new customers only and must be taken before any bets are placed with the qualifying deposit.

Sport Welcome Bonus

New customers who opt in during registration can double a first deposit of €20 or more with 100% up to €200. The bonus must be activated within 7 days and wagered 7x on qualifying sports bets within 30 days, with up to €1,000 transferable to the real balance. Cashed-out and voided bets do not count, nor do singles under odds of 1.90 or multi selections at odds of 1.51 or lower. The promotion runs from 21/04/2026 to 31/12/2026.

Casino Weekly Cashback

Losses are softened by 15% cashback on net weekly casino losses, paid up to €3,000 and refreshed every week.

Weekly Reload Bonus

The first deposit of €20 or more made between Monday 00:00 and Thursday 23:59 UTC earns 77% up to €700 plus 50 free spins on a selected slot. Wagering is 35x on deposit plus bonus and 35x on free spin winnings, with a €5 max bet, a 5x bonus cap on wins and 3 days to finish. Free spins expire after 2 days, the offer cannot be combined with others, and you must opt in each week.

Weekend Reload Bonus

Weekends bring a lighter top-up of 50% up to €700 with 50 free spins, open to registered players alongside the weekly reload.
