Field notes
The variant pages pair rules with cues about where each game is played and links to external references or player communities. Other sections are presented as practical study aids: tile illustrations, a glossary, timed quizzes, and a scoring calculator. The calculator is described as handling four scoring systems, while the page also says its tile section covers 43 tiles.
