CosmicSlot Casino gives existing players a 35% deposit bonus worth up to €400. The minimum deposit is €30; the bonus carries a 30xB wagering requirement.
Slots are the only games that count toward the playthrough. The most a player can cash out from the bonus is €400. The offer closes on 2026-10-24.
The percentage is modest compared with a standard match, but the cap on winnings matches the cap on the bonus itself (which keeps the terms easy to read). A €30 deposit earns €10.50 in bonus funds. A deposit of €1,143 or more reaches the €400 ceiling.
It's built for slot players who already hold an account and want extra playing time without a large upfront outlay. The 30x playthrough applies to the bonus amount, so a €400 bonus needs €12,000 in slot bets before withdrawal. Check the expiry date before depositing, since that's the one deadline the offer doesn't extend.
The wagering requirement is 30× the bonus amount.
The minimum deposit is €30.
The maximum cashout is €400.
