GeoDuo is a daily geography puzzle that presents a single shared border and asks players to identify the two countries or territories it separates.
Editor takes
GeoDuo's a perfect daily pit-stop for anyone with a spare coffee break and a hankering to feel clever.
GeoDuo's real delight is that it gives you a globe to spin while your brain works out the geography.
Six attempts and a hint system that actually rewards your misses makes for a satisfying clean-sweep run.
How to play GeoDuo
Players have six attempts to select the correct pair of countries. The order of the answer does not matter, and correctly guessed countries are marked in green and can be kept for subsequent guesses. Each incorrect guess unlocks a new hint, progressing from regions and border length to the silhouettes of each country and finally their initials. The border is displayed on an interactive world map that can be zoomed, rotated, and panned. To keep the challenge fair, the border is fitted to the frame without a scale in kilometers, preserving the value of the length-based hint.
