The US division of UK bookmakers William Hill has added two more Nevada sportsbooks to its portfolio of managed properties.

On Monday, William Hill US announced that it had inked a “long-term” deal with Eldorado Resorts to “significantly upgrade” and operate the race and sportsbooks at the Silver Legacy Resort Casino (pictured) and Circus Circus Hotel Casino Reno, which Eldorado acquired from MGM Resorts last July.

The two parties aren’t strangers, as Hills has operated the Eldorado Resort Casino’s sportsbook since 2012. Hills says it aims to have the Silver Legacy’s all-new 7,200-square-foot sportsbook ready in time for the start of the 2016 NFL season, while the Circus Circus Reno sportsbook will also undergo a major renovation.

Nevada sportsbooks have been on a roll of late, setting a new revenue record for the third straight year in 2015 and starting off 2016 with a string of new monthly betting handle records. The sustained betting surge has local operators projecting total wagering handle of $5b this year, more than twice the sum reported in 2006.
