Winshark Casino runs a 40% deposit bonus up to €250 for existing players. The minimum deposit is €20, and the bonus carries a 45x wagering requirement.
The offer expires on 2026-10-28. The Madnessday Bonus is available every week on Wednesday from 00:00 UTC until 23:59 UTC. The maximum bonus bet amount is €5.
It's aimed at players who already hold an account and want extra funds for a Wednesday session. A €20 deposit is enough to qualify; the 40% match tops up the balance up to a €250 cap. Keep the 45x wagering in mind before you claim, and note the €5 cap on bets placed with bonus money.
The weekly window is tight: play starts at 00:00 UTC and closes at 23:59 UTC the same day. That's the full picture, and you'll see the terms at the cashier.
