The feature chests collect heraldic coins, the type of coin collected determining the effect—reel growth with expanding wilds and a symbol upgrade trail, shield collections to award jackpot tiers, or extra spins with multipliers. When multiple coins combine, their effects merge into a single Free Spins variant, reflecting the layered structure at the heart of the Knight’s journey. Gold Coins fill the Gold Crown with a chance to win the Flag Spin feature, engaging all active flags for a single spin that can trigger and upgrade any combination of the Free Spin features.
