The launch means SuperBook’s reach now extends to six states, with the operator also live in Arizona, Colorado, Nevada, New Jersey and Tennessee, with further roll-outs planned in other states.
In August, SuperBook also announced it was to open a new retail sportsbook at Oriole Park at Camden Yards ballpark, the home of Maryland-based MLB franchise the Baltimore Orioles.
“From the Cyclones and Hawkeyes to the Field of Dreams, Iowa has one of the best sports traditions in the country,” SuperBook chief executive Mark Lipparelli said. “Many sports fans from Iowa have undoubtedly visited our iconic Las Vegas sportsbook and now they can access those same great betting options from home.”
SuperBook’s vice-president of race and sportsbook operations, Jay Kornegay, added: “I’ve known sports fans in Iowa to be among the most loyal and knowledgeable. We’re off and running and we welcome new sign-ups to compare us against the others.
“We focus on building the best odds anywhere we operate and we offer several generous odds boosts and other promotional bets.”
