Casinos across Indiana are preparing to launch legalized sports betting after a new state law was passed this spring allowing betting on international, professional and collegiate sports to start Sept. 1.

The new law will allow sports wagering by anyone 21 or older at a casino or by mobile devices after a bettor has registered with a casino in the state. The betting app will only work inside state borders, meaning people from outside the state will have to cross into Indiana to place a wager.

Casinos are rushing to get operations up and running as quickly as possible with the NFL and collegiate football seasons starting up.
