The Cartographer's Lie: now on Android

About this product

A daily deduction puzzle on a nautical chart. One hex on today's island is drawn as something it is not. Every survey note is true, and only one hex can satisfy them all. Find it and file your correction; you get three. New since our first launch: the Android app, spoiler-free share cards with a beat-my-time challenge, and Google sign-in. Casual and Standard charts are free in any browser, no account needed. Hard and Fiendish, streaks, ratings and duels live in the iOS and Android apps.
