Ceasars Growth Partners' businesses include Interactive Entertainment, which operate the company's regulated online gambling. Three states, including gambling centers Nevada and New Jersey, are the first to legalize Web-based casino games.   Interactive Entertainment would run the World Series of Poker and offer mobile and social games.
