Winspark's 100% deposit bonus doubles what existing players put in; it runs on Wednesdays only. The code is WED100.
A minimum deposit of €20 applies (and there's no cap on how much can be deposited). Bonus funds carry a 50xB wagering requirement and work on slots. The bonus has to be played and wagered within 30 days of a successful deposit.
After that it's void and revoked. The offer closes on 2026-10-21. It suits players who have already made at least 1 deposit and want extra funds for slot play midweek.
