MobileWins Casino runs a free spins offer from Monday 00:00 GMT to Thursday 23:59 GMT. Deposit at least £20 and enter code MBOX to receive one Mystery Box minigame.
The box awards between 25 and 100 free spins at random. Spins work on slots only. The bonus carries a 50xB wagering requirement and it's redeemable once per day.
The offer ends on 2026-11-05. It's aimed at players who deposit small amounts; you'll get a weekday spins bonus instead of a large welcome package.
