This document includes a series of numbered rules followed by a glossary. Many of the numbered rules are divided into subrules, and each separate rule and subrule of the game has its own number. (Note that subrules skip the letters “l” and “o” due to potential confusion with the numbers “1” and “0”; subrule 704.5k is followed by 704.5m, then 704.5n, then 704.5p, for example.)
