4Kasino hands out 350 free spins for bets placed on Sunday. The qualifying window runs from 00.00 CET/CEST to 23.59 CET/CEST.
Any slot game counts, except free spin bets, as long as the total bet amount reaches €100 or more. Bets on games other than slots don't count. The spins are credited on Big Bass Bonanza 1000, with each spin valued at €0.10.
Where Pragmatic Play isn't available, the spins go to Betsoft's Fruit Zen instead (also €0.10 per spin). A 35x wagering requirement applies; the offer ends on 2026-10-25.
The promotion is open to all players. It suits anyone who already plays slots on Sundays and can reach the €100 bet threshold without changing their usual routine.
The wagering requirement is 35×.
The minimum deposit is €100.
No bonus code is needed — open the offer at 4Kasino to claim it.
This offer is valid until 2026-10-25.
