About

Chartle is a daily "guess the chart" game for people who follow markets. Every day at midnight UTC, four anonymised price charts go live — one each at four difficulty tiers. You have six guesses to identify the ticker (and end year, on Easy/Medium/Hard).

Each puzzle is a real moment in market history — a famous rally, a memorable crash, a meme-stock squeeze. The chart is stripped of every label except its shape; that's the puzzle.

Got a memorable chart moment that should be a Chartle puzzle? DM it to me on X. Especially keen on niche events, regional stocks (EU, Asia, LatAm), commodities, and crypto cycles I might have missed.
