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 Schläfli double six In geometry, the Schläfli double six is a configuration of 30 points and 12 lines, introduced by . The lines of the configuration can be partitioned into two subsets of six lines: each line is disjoint from (skew with) the lines in its own subset of six lines, and intersects all but one of the lines in the other subset of six lines. Each of the 12 lines of the configuration contains five intersection points, and each of these 30 intersection points belongs to exactly two lines, one from each subset, so in the notation of configurations
