The Darker Side of OzĪs soon as you open the game, you know you're stepping into the darker side when you see the hauntingly lonely forest background in shades of black and purple. With 30 paylines across 5 reels, even the bonuses are designed around her destructive presence, featuring her ominous flying monkeys and the legendary tornado. WMS offers a range of Oz-themed games, including the Wizard of Oz Ruby Slippers slot machine as well as the original Wizard of Oz slot machine, but Wicked Riches is perhaps the darkest of them all, as it moves away from Dorothy's story and centers upon the Wicked Witch herself. The Wizard of Oz is a classic story for good reason and it translates perfectly into a wickedly fun slot gaming experience.
