Winner Island promotions — FAQ
What is the Winner Island Casino welcome bonus?
A four-part welcome pack worth up to 1,000 plus 100 free spins on Sweet Bonanza or Big Bass Bonanza. The first deposit is matched 100% up to 500 with 100 spins, then 75% up to 250, 50% up to 150 with 50 spins, and a final 100% up to 100 with cashback.
What are the wagering requirements at Winner Island?
35× the bonus amount for cash bonuses and 25× the winnings for free spins. Wagering is on bonus funds only — your real money balance always plays first. Slots contribute 100%, live game shows 20%, classic table games 10%.
How long do I have to clear wagering?
30 days for cash bonuses and 7 days for free-spin winnings. Any unused bonus funds or wagering progress are forfeited at expiry — we send a reminder email 48 hours before.
Is there a maximum bet during bonus play?
Yes. The maximum stake per spin, hand or bet while bonus funds are active is 5. This applies to total stake on a game round, including all paylines and bonus features.
Can I claim more than one promotion at once?
Only one bonus can be active at any time. Once you complete or cancel an active bonus, your next eligible promotion unlocks automatically.
Do I need a bonus code?
Most Winner Island Casino promotions are claimed with a single click — no code needed. A few exclusive offers (e.g. Telegram drops or affiliate codes) require a short code, which is shown in the offer details.
