WYANDOTTE, Okla. (AP) – A $30 million expansion to the Wyandotte Nation Casino is expected to add up to 50 jobs in northeastern Oklahoma.

The tribe unveiled plans Monday for the three-phase expansion. Plans calls for the casino to double in size to 50,000 square feet and add a bowling alley, multipurpose club and an entertainment venue that will seat up to 500 people.

Wyandotte Nation Chief Billy Friend says the casino hasn't had many updates since it opened in 2007. He says northeastern Oklahoma is a highly competitive market for casinos.

The Miami News-Record reports that more than a dozen casinos or gaming venues are located in Delaware and Ottawa counties.

The Wyandotte tribe has more than 1,100 members in Oklahoma and more than 5,000 nationwide.
