In-person registration is required for those choosing to use mobile apps, which is in place until January 2021.
Betting on college games will be allowed, but prop bets involving in-state college teams will be prohibited.
Iowa has 19 casinos that are now eligible to offer sports betting.

It is expected both DraftKings and FanDuel’s sportsbook will be granted access to the market. DraftKing’s formed a partnership with Caesars and FanDuel struck a deal with Boyd Gaming. Both of these casino companies own properties within the state of Iowa.
