Blue Fox Casino runs a free spins offer from Monday 00:00 GMT to Thursday 23:59 GMT. A minimum deposit of £20 with code MBOX gives players one Mystery Box minigame.
The box awards 25 to 100 free spins at random; the spins work on slots. The bonus carries a 50xB wagering requirement and can be redeemed once per day. It's open to all players.
The offer closes on 2026-10-29. That's the full window.
