Caesars Racebook expanded into its third state for mobile horse betting Wednesday, launching in Indiana ahead of Saturday’s Belmont Stakes.

The mobile app, having originated as a partnership between Caesars and the New York Racing Association in January, launched in Ohio and Florida last week. Caesars owns both horse racing tracks in Indiana – Harrah’s Hoosier Park and the recently rebranded Horseshoe Indianapolis, which was previously Indiana Grand. They are both racinos that also offer casino gaming and sports wagering.

“The launch of Caesars Racebook is an important milestone as we continue to add wagering opportunities for our customers and livestreaming content for the first time,” Dan Shapiro, senior vice president and chief development officer of Caesars Digital, said at the time of last week’s initial launch.
