The bonus is wagered 50x within 30 days, and up to three times the bonus amount then converts to real money. Free spin winnings are wagered 50x within 7 days, with a maximum conversion of €20. Deposits must go through the casino cashier, and deposits made with Skrill or Neteller are excluded from all bonus offers. Wagering is taken from the real money balance first, only one bonus can be active at a time while the others wait as pending, and a withdrawal request cancels all active or pending bonuses. Under the bonus policy, video poker counts 5% towards wagering; blackjack, baccarat, roulette, poker table games and jackpot games count 10%; and games on the excluded list count 0%. A fixed maximum bet with a bonus is not published; the general terms list a single bet of more than 25% of the initial deposit among irregular playing patterns.
The weekly offers are each opened with a deposit code through the casino cashier:
- Weekend Wheel of Spins (code WKND500), from Friday 01:00 CET to Monday 00:59 CET, once a day: a deposit from €20 gives one spin of the wheel, valid for 24 hours, for 5 to 500 free spins. 30 free spins is the most likely result at 25%, and 500 free spins comes with a 1% chance.
- Midweek Wheel of Prizes (code WED500), from Wednesday 01:00 CET to Thursday 00:59 CET, once a week: the same wheel, with the same prizes and odds, for a deposit from €20.
- Mystery Box (code MBOX), Monday to Thursday, once a day: a deposit from €20 gives a box, valid for 24 hours, holding 25 to 100 free spins. 25 and 35 free spins come at 36.5% each, and 100 free spins at 0.94%. The offer itself speaks of up to 400 free spins a week.
On all three, free spin winnings are wagered 50x within 7 days and up to €20 can be converted.
Two dated offers run as well. SHADOW25 gives 25 free spins on 3 Shadow Wolves (Spinomenal) for a deposit from €10, claimable up to three times until 29 October 2026 at 00:59 CET.
