Operators in Delaware were forced to suspend operations for more than four months between mid-March and July as a result of state-wide restrictions related to Covid-19.
Delaware only permits land-based sports betting, and as all gambling venues had to close for more than four months, this meant punters were not able to legally bet during that time.
Dover Downs and Harrington Raceway reopened their sportsbooks in July, but the retail facility at Delaware Park remained closed during the month and did not resume operations until August 30.
