Players use the visible dates, units, axis scale, and line pattern as clues before drawing across the hidden portion. The instructions explain how to revise a guess and review a completed set, while the listed categories range from Economy and Nature to Culture & Leisure. The page says the question bank contains more than 300 charts and describes source links for checking what each series measures.
