A medieval fantasy style slot machine inspired by the aesthetic of 'The Lord of the Rings'. On the left, a goblin is peeking out, holding a diamond above his head. The slot machine itself is embellished with magical runes and inscribed with 'Watcher's Slotmachine' at the top in an ancient script. The design should invoke a sense of medieval magic and adventure, with detailed textures and atmospheric lighting to enhance the mystical feel.
