Nevada sportsbook operator, William Hill US, reported a record-breaking first four days of March Madness with cumulative handle taken at its 108 Nevada sports books and on the mobile sports app surpassing a record last year by 30 percent.
For reference, the cumulative handle on the College Basketball Championship Tournament for the first three days (Thursday, Friday, and Saturday) bested the total handle of Super Bowl 51 (including all prop and futures bets), the company said.
