The Cartographer's Lie: now on Android - One hex on this chart is a lie. Find it. A new map daily.

Hi Product Hunt. I'm Kevin, I made this alone over the summer. I wanted a daily puzzle where the reasoning was spatial rather than lexical: instead of guessing a word you're triangulating a position on a map from clues that are all true at once. The chart is engraved in the style of old hydrographic surveys because that's the fiction: you're a surveyor correcting someone else's chart. Since the first launch here in September the Android app has shipped, the share grid became a proper share card with a beat-my-time challenge, and Google sign-in works on both phones. The web version is free and plays in the browser; the apps add the harder tiers and the social layer. I read every comment, and if the puzzle is too easy or too hard on a given day, I want to know.
