In 1984, stuntman Dan Koko set two world records for separate stunts in which he jumped from the rooftop of Vegas World's 25-story hotel tower. Vegas World featured the world's first quarter-million and million-dollar slot-machine jackpots, as well as the world's largest mural, the world's largest Big Six wheel, and reputedly the world's largest exterior sign. Vegas World closed on February 1, 1995, to be remodeled and integrated into Stupak's new project, the Stratosphere. Vegas World's two hotel towers were renovated for use as the Stratosphere's hotel.
