SuperBoss Casino 40 Free Spins

SuperBoss Casino gives existing players 40 free spins on The Castle of Slotenstein by Evoplay. The code hallowin activates the offer, which runs until 2 November 2026.

Spins carry a 40x wagering requirement before any winnings can be withdrawn. The Castle of Slotenstein is the only game the spins work on; there's no choice of slot here. That suits players who already know the Evoplay title and want extra rounds on it.

Anyone hoping to spread the spins across other games won't find that option. The offer is built around a single game and a single code: enter hallowin in the bonus field to claim the 40 spins before the expiry date. Existing players qualify, new accounts don't.

Check the wagering terms in the cashier before playing, since the 40x requirement applies to what the spins produce. The code is case-sensitive as shown.
