When this occurs, the player who has been declared dead no longer participates in the game, and the game continues with the remaining players. Your own hand might also go dead, but if this is the case you need not disclose it to any of the other players and should try to find a backup hand. Another way to call a player’s hand dead is to say, “your hand is no longer viable” or “your hand is invalid”.
Dealing the Tiles
The process by which all four players pick in succession a set of four tiles each until all four players have 12 tiles. Once all four players have their 12 tiles, East (player 1) picks the first and third tile off the top row, and all others pick the very next one available.
