The horror movie release, timed to Halloween, attracted more moviegoers at the box office than the violent Keanu Reeves thriller "John Wick." The R-rated hit-man revenge tale opened with $14.2 million in second place.
Last week's top film, the Brad Pitt World War II action film "Fury" slid to third with $13 million in its second week.
Board-game adaptions like "Ouija" have had a checkered history at the box office, with the big-budget "Battleship" famously flopping. But "Oujia," released by Universal Pictures, was made for just $5 million, and scared up moviegoers with a micro-budget summoning of brand-name occult.
