For 40 years the game has been played by four people, with the winner being the first player to score 150 points, in multiples of five, by using 27 bones, using mathematical strategic defenses and explosive offense. At times, it has been played with pairs of partners. The double-six set is the preferred deck with the lowest denomination of game pieces, with 28 dominoes.

Schläfli double six formed in this way are all in turn intersected by another line, "a". The twelve lines "a" and "b" form a double six: each line "a" has an intersection point with five of the other lines, the lines "b" for which "i" ≠ "j", and vice versa. An alternative construction, shown in the illustration, is to place twelve lines through the six face centers of a cube, each in the plane of its face and all making the same angles with respect to the cube's edges. A generic cubic surface contains 27 lines, among which can be found 36 Schläfli
