- People who enjoy history and chain puzzles
- Worth noticing
- Dates and descriptions come from Wikidata; sharing a year of life counts as an overlap, including a person's death year.
Field notes
A guess may push the chain forward or become an island or detour that can be linked later; the rules distinguish those outcomes from a miss. Par changes with the difficulty of the stretch and its rules, and the page includes a puzzle lab for exploring endpoints, years, or a rule alone. The listed source for dates and descriptions is Wikidata.
