SuperBoss Casino gives existing players 40 free spins. The bonus code is **hallowin**.
Spins work on The Castle of Slotenstein by Evoplay. Wagering is set at 40x. The offer expires on 2026-11-02.
The code has to be entered to claim the spins; the 40x wagering applies before any winnings can be withdrawn. The spins are limited to the Evoplay slot named above, so other games don't count toward clearing the requirement. The expiry date is fixed (and the offer closes on that day).
This one suits players who already hold an account at SuperBoss Casino and want spins on a single Evoplay title. Anyone new to the site can't claim it, since the bonus is for existing players only. The spin count is modest at 40, and the 40x wagering is worth checking against the slot's volatility before opting in.
Players who prefer a wider choice of games may find the single-title restriction narrow. Those who already play The Castle of Slotenstein get a straightforward addition to their session.
The wagering requirement is 40×.
