Where did the title jumanji come from?

The title "Jumanji" comes from a fictional Word created by author Chris Van Allsburg for his 1981 children's book of the same name. In the story, Jumanji is a magical board game that transports players into a jungle adventure filled with dangerous challenges. The name is derived from a South African Word meaning "many effects" or "many things," reflecting the game's unpredictable and transformative nature.
