21Bets runs a 25% cashback deposit bonus worth up to €150. The offer applies to bets placed on Thursday, from 00.00 CET/CEST to 23.59 CET/CEST.
Cashback lands in the customer account within the next calendar day. Slots are the only qualifying games. The maximum cashout is €150 (which matches the cap on the bonus itself).
The promotion closes on 2026-10-22 and is open to all player categories. It suits regular slot players who already put money through the site on Thursdays and want part of their play returned the following day.
The percentage is fixed at 25%: the cashback scales with the amount bet, not with the deposit size. Bets placed outside the Thursday window don't count toward the calculation.
The maximum cashout is €150.
No bonus code is needed — open the offer at 21Bets to claim it.
This offer is valid until 2026-10-22.
