Tjak-ma-tchi-ki, "pair making," is played by 2, 3, or 4 persons. The pieces are reversed and shuffled and covered with paper.

The first player draws 6 and the other players each draw 5 dominoes. The first player endeavors to play out a pair from those he has drawn, but if he is unsuccessful he lays out 1 piece face up on the table.

The second player takes up the piece discarded if he can combine it with a domino in his hand to form a pair. If not, he draws a piece from those left under the paper, and discards a domino, which he lays out face up. This process is continued around until 1 player gets 3 pairs in his hand, and becomes the winner.

When 2 or 3 play, the 6-6 can not be played to complete the third pair, but when 4 play it may thus be played and the winner must be paid alone by the player who discarded the corresponding piece.

If the pair is completed by a piece drawn from the unused pile, all the other players pay the winner, but if it is completed by a piece which has been discarded, the player who discarded that piece alone pays the winner. It is sometimes agreed that the third pair by which a player wins must be completed with a piece drawn from the unused pile.
