Starting Thursday at noon, people in Iowa can start placing bets on sports at all but one of the state-regulated casinos.

Earlier this year Governor Reynolds signed a law letting people bet at state-regulated casinos.

They can also bet on their phone through an app connected to the casino. The decision came after the United States Supreme Court put the power to allow sports betting into the hands of the state.

The Isle Casino in Waterloo is holding a ribbon-cutting event on Thursday in honor of the change. Major League Baseball hall of Famer Andre Dawson will be on hand to make the first bet.

People can bet on both professional and college games. The catch with college games is that people can't bet on individual players. People can make in-game bets and prop bets for professional games.

Casinos will have information available to give people about gambling addiction.

Workers with Isle Casino say their workers are also trained to talk to people about gambling addictions

Overall, this could mean huge money for the state. Sports betting website PlayIowa.com says it could eventually bring in more than 5 billion dollars per year.

“Now you can place a bet, it's legal. (It’s) going to be taxed,” said Thomas Roberts, the general manager of Isle Casino. “Those tax dollars, 3% of that is gonna go to the local charitable foundation here, and it's going to be given to the surrounding counties, so now that that that money that was going illegally to be gambled is going to be brought to the forefront."
