There’s a slot machine at MGM that hasn’t paid out a jackpot in twenty years. With a progressive payout now over 2.3 million dollars, people have been flocking to play this slot for years.  But they all keep losing. Gamblers looking for a big payday have been making pilgrimages to this machine -- an outdated Lion's Share three-reel slot machine that most casinos would have abandoned. But until a jackpot is paid, the machine will stay.  Rob Copeland from the Wall Street Journal explains the cult status of this legendary machine.
