Chartfall — Daily Data Detective

Play short offline puzzles that teach you to spot misleading charts and repair overconfident claims.

Chartfall turns careful chart reading into a short daily quest. Each fictional case gives you a chart and a confident headline. Find the strongest visual or methodological clue, choose the claim the evidence can honestly support, then compare the repaired view. A full run takes about four minutes. ### What is included - 24 authored fictional cases across axes, samples, rates, time windows, causation, and uncertainty - one deterministic five-case daily quest - six focused practice paths - an explainable debrief and repaired chart after every case - a field guide, local mastery map, streaks, and session recovery - keyboard choices, reduced-motion support, and an optional high-contrast chart palette - a polished 420×600 launcher and a full quest-ledger workspace ### Private by design Chartfall works entirely inside the extension. It does not read webpages, connect to a server, show ads, require an account, or send analytics. The only Chrome permission is `storage`, used for game progress, the open quest, onboarding state, and preferences. Use **Clear my Chartfall data** at any time to remove that local state. Chartfall is educational practice with fictional scenarios. It is not a fact checker, truth-rating service, or substitute for statistical, medical, legal, financial, or professional advice. ## Search phrases reflected naturally in the product misleading charts, misleading graphs, chart literacy, data literacy game, critical thinking game, graph reading practice, educational browser game, offline game ## Listing integrity The screenshots show the shipping interface at its real 1280×800 workspace size.
