As revenues plunge at closed Iowa casinos, bettors turn to ‘Ping-Pong’ Rod Boshart, Sioux City Journal · April 14, 2020 at 3:57 pm DES MOINES — Iowa’s state-licensed casinos are coming to grips with the grim-looking revenue projections brought on by a coronavirus pandemic that has closed their doors and shut down sports wagering opportunities at least into next month. Figures issued by the state Racing and Gaming Commission indicate adjusted gross revenues in March fell by nearly half. The state’s 19 casinos were ordered to close March 17 as part of Gov. Kim Reynolds’ public health emergency order designed to slow community spread of COVID-19 in Iowa. Those closings followed the cancellations of professional and collegiate sports, which brought Iowa’s fledgling and promising sports betting to a virtual halt just as casinos were gearing up for their first March Madness college basketball tournament since Iowa open the new wagering activity last August.
