Building the wall: Dealer and opposite player build a 19 x 2 wall. The other two players build an 18 x 2 wall.
Breaking the wall: Dealer rolls two dice to get the sum x, then counts x players in a counterclockwise direction, starting with themself (i.e., the count should land on the player in the seat that’s x modulo 4). The player whose wall was chosen rolls two dice to get the sum y. Count x + y tiles from the right of the chosen wall, then stack the x + y tile on the tile to its right.
Dealing: In a counterclockwise direction, deal 4 tiles to the dealer, 4 tiles to seat 2, 4 tiles to seat 3, and so on until every player has 12 tiles. Give the dealer 2 more tiles by picking up the next tile of the first column, skipping the next (second) column, then grabbing the top tile of the third column. Give seat 2 the bottom tile of the first column, give seat 3 the top tile of the skipped (second) column, then give seat 4 the bottom of the skipped (second) column.
Winds and seats: East = seat 1 (dealer), South = seat 2, West = seat 3, and North = seat 4. The seats are assigned counterclockwise from the dealer and rotate counterclockwise if a player besides the dealer wins. If there is a draw, the seats do not rotate. When the first dealer becomes dealer again, the prevailing wind changes (same order as the seats: it starts as East, then becomes South, West, North).
