LAS VEGAS (AP) — Three more casino operators have been issued a Nevada online poker license.

The state Gaming Control Board on Thursday approved interactive gambling licenses for MGM Online LLC and boutique firms Z4Poker LLC of Las Vegas and Cams LLC of Los Angeles.

Interactive licenses allow a company to operate online gambling sites in which live players within Nevada borders compete against each other.

The three companies join more than a dozen others that have received licenses so far.
