The Green Knight is a 5-reel, 20-payline video slot. Landing 3+ Green Knight symbols triggers 5 Free Spins, with the Shield as a Wild symbol. The Shield can be a Multiplier Wild (X2, X5, X10, X25, X100) and increase wins when substituting. During Free Spins, the Shield is a guaranteed Multiplier Wild, with increasing values. The Special Green Knight symbol replaces the Green Knight, and 2+ award 5 Shield Spins, pausing Free Spins. The triggering Multiplier Wild value carries over to Shield Spins, and Free Spins resume afterward.
