Nevada gambling officials approved rules Thursday to limit customers, keep gamblers spaced apart from each other and disinfect dice and cards when the state’s casinos are allowed to reopen. The Nevada Gaming Commission, which is considered the final authority on regulations and licensing, unanimously approved the guidelines that were released last week by the Nevada Gaming Control Board, which sets rules and regulations. Meantime, Nevada will begin allowing restaurants, salons and other nonessential businesses to reopen starting Saturday, Gov. Steve Sisolak announced, the first easing of restrictions imposed seven weeks ago to stop the spread of the coronavirus.
