The Navajo Nation on Monday signed an agreement under which it will lease the rights to more than 1,000 slot machines to three gaming tribes near Phoenix and Tucson. The deal, also signed by the Gila River Indian Community outside Phoenix and Chandler, the Fort McDowell Yavapai Nation, north of Fountain Hills, and the Tohono O'odham Nation, near Tucson, is expected to generate more than USD 100,000 for the Navajos over several years.
