Set of 55 dominoes DOUBLE NINE Halsam, Miltob Bradley 1970's

Domino size  2 x 1 x 1/2

The object of the game:

In practically all domino games the players strive to block the game so that others cannot make a play; or to make ends when added together equal some given number or multiple of that number; or to so play that the ends of the line will show "spots" of equal value. A player goes "domino" when he plays his last piece before any opponent.
