The 06 World Series of Poker championship had some 8700 players anteing 10,000 to play. That means each player started with 10,000 in chips for a total of about 87,000,000 million in play.
At the final table the 9 players started with 91,000,000 at the table. Now the players never leave with their chips. You leave them on the table at the end of the day and the house counts and records your winnings. On the next day your chips are placed at your assigned seat.
Well, if there was 87 mil at the start, how did 4 mil more enter the game ?
That is the subject of a Las Vegas Gaming Commission investigation now going on in Vegas right now.
