5th Player Bets on East with an Earthly Hand (Article ID 140)
Abstract: If East is lucky enough to have a winning hand after the Charleston, the hand is considered self-picked and the value of that hand is doubled. This is called an “Earthly Hand.” If the 5th player bet on East, they are paid just like the winner.
Question from a player: Does the bettor get paid if they bet on East and East has a winning hand after the Charleston?
Answer: If a bettor is lucky enough to have bet on East, and East ends up with a Heavenly Hand, they are paid the same value as paid out by all other players.
