The board’s 4-0 vote on Tuesday removed one of the final obstacles to the casino.

Spokesman Scott Smith says casino operators are now putting their focus on ensuring 350-plus full-time workers are hired and trained to ensure a smooth opening in early June.

The casino already has taken delivery of 500 slot machines, and they’re being installed. The Oxford Casino also plans to have 12 table games — craps, roulette, blackjack and poker — when it opens.
