- Scores use mean absolute miss against the y-axis range, and arrow keys work when a chart is focused.
Field notes
Each chart is scored by mean absolute miss relative to the y-axis height: staying within 1% earns 1,000 points, with the score reaching zero at roughly 31%. The page says the daily five use yearly series from Our World in Data, with source links and CC BY credit; keyboard arrows also work when a chart is focused. Completed daily scores are stored in the browser.
