2.2 The Deal
The complete game of Mah Jong ordinarily consists of 16 hands (or deals), though the number may be increased each time the dealer (East) wins, or when a deal ends in a draw. Each hand begins with the building of the Wall, breaking it, and dealing the tiles.
Before the game starts players throw the dice several times in order to determine the seat order, the first dealer (East) and to determine the place where the Wall is to be broken.
Before each hand all the tiles are placed face down on the table and thoroughly mixed by non-dealers, until East gives the command 'Pow' (meaning 'start'), after which each of the four players picks up 34 tiles and builds a row of tiles in front of him, 17 tiles long and 2 high (if Flowers and Seasons are used, 36 tiles are picked, forming a 18 tiles long row; if only Flowers are used, East and West build a 18-tile long row and South and North build a 17-tile long row). Each player then pushes his row forward to form a hollow square. This formation is called Wall
To determine the breaking point of the Wall, the dealer (East) throws the two dice and counts counterclockwise round the walls, beginning with himself as one (accordingly, numbers 5 and 9 indicate East, numbers 2, 6 and 10 South, numbers 3, 7 and 11 West and numbers 4, 8 and 12 North). East then counts off along the tiles of the top tier of the wall indicated by the dice (a stack of two tiles at a time), starting from the right end. E.g., if he throws 6, he will count 6 stacks from the right end of the South's wall.
Note: Some players use a rule according to which East of the very first deal does not throw dice to determine the breaking point of the Wall but instead breaks his own Wall at the point indicated by the last throw of dice (e.g., in the example above four was thrown).
East makes a break in the wall by pushing slightly the tiles to the left of the breaking point.
The eight stacks of tiles to the right of the breaking point are known as Dead Wall
(or Kong box
); the remaining tiles, starting from the tiles to the left of the breaking point, constitute the live Wall. The 16 tiles of the Dead Wall are reserved as replacement tiles for Kongs (and Flowers and Seasons, if they are used). The Dead Wall is replenishing so the used supplement tiles are replaced by reserving new tiles from the tail end of the live Wall (however, the supplement tiles are always taken from the left end of the Dead Wall).
East starts the deal by taking the first two stacks of the tiles (i.e., four tiles) from the left of the break, then each of the other three players pick two stacks of tiles in order South, West and North. This is repeated three times so that each player has 16 tiles. East then draws one additional tile. Thus the dealer has 17 tiles and the other three players each 16 tiles.
The hand starts by each player arranging the dealt tiles so that their faces are not visible to the opponents, but in such a way that the other players may count them.
If Flowers and Seasons are used, and the dealt hand contains Flowers or Seasons, they are immediately melded (placed face up above and to the side of the hand) and replaced with regular tiles taken from the Dead Wall (East replaces first his extra tiles, then South, West and North). Should a player draw further bonus tiles during this replacement procedure, he must wait until the other players have drawn their supplement tiles before replacing further tiles.
