Wizard of Oz Road to Emerald City represents the 7th entry in this growing series, with it possibly having the power to be the most potent game of the bunch. What’s probably helping WMS remain in the spotlight is the Wizard of Oz Road game series, which seems to be generating serious momentum through its latest entry. While they haven’t been able to release a game that’s truly been ground breaking as yet, the developer’s back catalogue is still undeniably stellar. When you think WMS, you probably think of online slots, as the developer has pushed out plenty of popular releases over the years. Wizard of Oz Road to Emerald City Slot Machine
