About Tectonic

Play Tectonic — Free. No sign-up needed.

Build the world outward from one seed country on a real 3D globe. Only neighboring frontier countries are available, turning map knowledge into a geographic deduction puzzle.

Daily Globe is part of the official set. Arcade and Zen add optional globe runs, while Tectonic Regions offers 200 flat-map puzzles covering continents, islands, countries, and subdivisions.
