Only Win Casino runs a Sunday Boost deposit bonus. It adds 20% up to €100 and it's open on Sundays from 00:00 to 23:59 UTC.
Players need at least 4 deposits to qualify. The bonus can be activated once per day, and activation lasts 2 days. Wagering must be completed within 3 days.
The minimum deposit is €20, and wagers are set at 40x(D+B). Slots are the only valid games. The maximum bet while wagering is €5, and the maximum cashout is €700.
You'll find the Sunday Boost in the "Bonus section" of your account. The offer expires on 2026-10-25. It suits regular players who already have 4 deposits on record and want a small top-up for Sunday slot play.
