JeffBet Casino runs a free spins offer for existing players. The promotion is open from Monday at 00:00 GMT until Thursday at 23:59 GMT.
A minimum deposit of $20 with code MBOX earns 1 Mystery Box minigame. The box awards 25 to 100 free spins at random; the amount can't be chosen. Winnings carry a 50x wagering requirement.
The bonus can be redeemed once per day. The offer ends on 2026-10-29. This suits players who already hold an account and deposit during the Monday to Thursday window.
The code has to go in at deposit, since the Mystery Box depends on it. Spins are awarded through the minigame, not credited straight away. Check the daily limit before depositing a second time in the same day.
The wagering requirement is 50×.
The minimum deposit is $20.
Yes — use bonus code MBOX when you claim the offer at JeffBet Casino.
This offer is valid until 2026-10-29.
