Vegas' hottest slot machine isn't what you think

The hottest attraction in Las Vegas is an outdated three-reel slot machine that hasn't produced a jackpot in almost two decades. Called the Lion's Share, it's in the MGM Grand, the Strip's second-biggest casino.

'This game probably gets played about five times more than the average game on our casino floor. Our staff gets asked multiple times a day every single day where this game is from people that haven't played it before,' Justin Andrews, Executive Director of Slots at the MGM Grand, explained.

Because a generation of players has already lost their money, the Lion's Share jackpot has more than doubled ... to a whopping $2.3 million.

The track record also makes it among the rarest of Vegas treats: a decent bet.

One expert says it may approximate an even money bet. MGM officials confirm that each day without a winner pushes the odds closer to a player's favor.

Andrews says that MGM will keep the game 'as long as it's in working order -- and until that jackpot pays out.'
