A simple game called tiú ü, "to angle," is played by 2 or 3 persons with 2 sets of dominoes. The pieces are well mixed and piled face down, side by side, in a stack 4 high.

Four piles of 4 each are now drawn from one end of the stack and placed face up on the table. When 2  play, both players draw 3 piles (12 dominoes), or if 3 play, 2 piles (8 dominoes) from the same end of the stack. The players then examine their pieces, and the first player endeavors to mate one of his pieces with one having the same number of spots among those [Page 512] turned up on the table.

If successful, he places the mated pair, face up, before him. In either case he draws the bottom piece of the pile at the end of the stack from which the last piles were drawn and endeavors to mate it with one of those on the table. If successful, he takes the pair, but if not, he places the piece drawn among those on the table. The second player then tries to mate one of his pieces, and also draws one from the stack, and the game is continued in this manner until the stack is exhausted. A pair of double "sixes" in a player's hand is at once laid out.

If a player holds a piece in his hand, identical with 2 pieces on the table, and the fourth piece of the same kind has not been played, he may, at his turn, pile the 3 pieces that are alike one upon the other, with the uppermost face up, at the opposite end of the stack to that drawn from, and the player who first lays out the fourth piece may take the 3 pieces. The 2 pieces composing the chí tsün mate with each other, and form an exception in this game to the rule by which all pieces having the same number of spots mate with each other without reference to their belonging either to the man or mò series.

When the last domino is drawn, the players examine those they have taken. The pieces on which the spots number 8 or more are called tái ü, "large fish," and count 2 points for each spot. The pieces below 8 are called sai ü, "small fish," and count 1 point for each red spot. If this latter sum is between 2 decades, the highest decade is counted. The player counting the highest becomes the winner, and is paid by each of the players for each point he has in excess.
