Hotwins Casino runs a free spins offer from Monday 00:00 GMT to Thursday 23:59 GMT. A minimum deposit of £20 with code MBOX earns one Mystery Box minigame.
The box awards 25 to 100 free spins at random, and the spins work on slots. It's redeemable once per day. Free spins carry a 50x wagering requirement (50xB).
The offer ends on 2026-10-29. That's a random prize, not a fixed amount. Players who deposit during the Monday to Thursday window don't know the spin count until the box opens.
