Ts'ung shap, "to dispute for tens," is played by 2 persons with 1 set of dominoes. The pieces are piled face down, side by side, in a stack 4 pieces high, which the players divide between them, each player taking 8 of the 16 piles.

The first player draws the top piece from the end pile towards the right of his pile, and lays it face up on the table. The second player, in turn, draws a piece and lays it face up alongside of the piece played by the first player. The players continue to draw and place the pieces on the table in this manner either on the right or left of the row thus formed. If a player lays down a piece which is a duplicate of one of the pieces at either end of the row, he takes both pieces called túi, a "pair," and they count 10 for each spot on them at the end of the game. Or, if a player lays down a piece on which the spots, added to those on 2 pieces at one end of the row, or on the pieces at each end, form a sum that is a multiple of 10, the player takes the 3 pieces, and they count 1 for each spot on them at the end of the game.

If there are but 2 pieces on the table, and a player takes them, he piles them upon each other to mark the play, called táp tí, literally "to tread on earth," i. e. - a "sweep," which counts 40. The winner draws and lays out another piece. Should he fail to take up a winning combination of  [Page 513] 2 or 3 pieces, his opponent may take it, and follow by laying out a piece and continuing the game.

The game proceeds until one of the players has laid out all of his pieces, when the one who counts highest wins.
