The hotel's casino operated until 1909, when gambling was banned in Nevada. The casino's blackjack and poker tables were subsequently put into storage. By March 1918, Miller was considering a large addition to the hotel that would consist of reinforced concrete and would include 40 feet of frontage along Fremont Street. The hotel gained additional popularity beginning in 1925, when city officials had Fremont Street paved. The Hotel Nevada reopened its casino in 1931, when gambling in Nevada was legalized again. That year, the property was expanded to four stories and renamed as the Sal Sagev (Las Vegas spelled backwards).
