A medieval fantasy style slot machine inspired by the aesthetic of 'The Lord of the Rings'. The slot machine features three prominent reels, showcased in full view as the main focus of the image. On the left, a goblin is peeking out, joyfully holding a diamond above his head. The machine itself is adorned with magical runes and is inscribed with 'Watcher's Slotmachine' in ancient script at the top. The design should capture the essence of a medieval magical setting with detailed textures, atmospheric lighting, and a mystical ambiance, emphasizing the three reels.
