Scruffy Duck takes players to a charming pond where a quirky family of ducks awaits. The game's central mechanic is the Expanding Wild feature, where the Scruffy Duck symbol can expand to cover an entire reel, transforming into a graceful swan. The Free Spins round offers five different feature choices, including Multiplier, Symbol Removal, Random Wilds, Colossal Wilds, and Expanding Wilds, adding variety to the gameplay.
