On a recent Thursday night, which kicked off a summer-long series of bingo events, more than 900 people gathered in the ballroom to share stories, hug longtime friends and play a game they love. To celebrate the 10th anniversary of the casino, the Pechanga Band of Luiseno Indians resurrected bingo, one of the early draws for the tribe when it was operating the casino’s forerunner, the Pechanga Entertainment Center, in the 1990s.
