Bonuses at Slim King

The promotions menu is split between casino and sports offers, each with its own welcome deal, alongside weekly cashback and two reload bonuses. Welcome bonuses are opted into at registration or from the "My Bonus" area after a deposit, while the weekly reload must be opted into each week.

Welcome Bonuses

The casino package spreads across four deposits: 100% up to €2,000 plus 150 free spins, 75% up to €2,500 plus 50 free spins, 75% up to €2,500 plus 100 free spins and 100% up to €3,000 plus 200 free spins. Free spins are credited in daily batches, and free spin winnings transfer to the real balance up to €50. The sports offer is a single match on the first deposit, running from 21/04/2026 to 31/12/2026 for new customers who opt in at registration.

Cashback

Cashback is paid weekly on net casino losses at 15%, capped at €3,000 per week.

Reload Bonuses

Two reload offers add free spins to a deposit match. The weekly reload applies to the first deposit made between Monday 00:00 and Thursday 23:59 UTC, with a €20 minimum, wagering of 35x on deposit plus bonus and 35x on free spin winnings, a €5 maximum bet, a 5x bonus win cap, three days to wager and free spins expiring after two. All registered users are eligible, and the weekly reload cannot be combined with another bonus.
