Zynga has launched a new mobile social casino game where you can travel through the Emerald City. The Wizard of Oz Slots is the latest game that the publisher has launched on mobile as it tries to get its mojo back in the social-casual gaming business.

This is a key launch for Zynga, as social casino games have become a $2.7 billion worldwide industry in a short few years thanks to rapid growth on Facebook and mobile. And the publisher lost money in its most recent quarter, as it tries to do a better job of making the transition from Facebook web games to mobile social games.

The game will be available on the App Store for iOS devices as well as the Amazon App Store for Kindle devices. The Wizard of Oz Slots is part of the Hit It Rich casino games, where you can purchase chips with real money but cannot cash those chips out for real-world cash.

Zynga aims to provide an authentic, arcade-like casino slots experience for Wizard of Oz fans. Each machine is based on a major chapter in the Wizard of Oz. So grab your ruby slippers.
