The casino also featured various memorabilia, including antique slot machines, a gambling chip collection, and photographs of former gambling figures such as Bugsy Siegel. Stupak said, 'The name was about 10 feet longer than the casino.' The casino featured 15 slot machines, including a quarter slot that offered a $250,000 jackpot and a nickel slot that advertised a $50,000 payout. On March 31, 1974, he opened a small casino called Bob Stupak's World Famous Million-Dollar Historic Gambling Museum and Casino. The land was occupied by the Todkill/Bill Hayden Lincoln Mercury car dealership, and was purchased by Stupak at a cost of $218,000, with money he raised himself and from his father's friends. In the early 1970s, Bob Stupak purchased 1.5 acres (0.61 ha) of land at 2000 South Las Vegas Boulevard, located north of the Sahara Hotel and Casino and the Las Vegas Strip, in a seedy part of the city.

Vegas World's two hotel towers were renovated for use as the Stratosphere's hotel.

Vegas World closed on February 1, 1995, to be remodeled and integrated into Stupak's new project, the Stratosphere. 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. 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. The casino was eventually expanded to 80,000 sq ft (7,400 m 2). A 25-story tower was added in 1984, and a new wing was added to the tower in 1990, for a total of 932 rooms. Vegas World opened with a 15,000 sq ft (1,400 m 2) casino, and 90 hotel rooms in an eight-story tower. Stupak later opened Vegas World on July 13, 1979, on the same property. Stupak initially opened a small casino, Bob Stupak's World Famous Million-Dollar Historic Gambling Museum and Casino, on the property in 1974, but it was destroyed in a fire later that year. It was owned and operated by Bob Stupak, and was also signed as Bob Stupak's Vegas World. Vegas World was a space-themed casino and hotel on Las Vegas Boulevard in Las Vegas, Nevada.
