Travle

A geography puzzle about adjacency. You are given a starting country and a destination, and you have to name a chain of countries that share borders to get from one to the other — which tests a kind of knowledge most people have never organised: not where places are, but what they touch. That is a genuinely different skill from map recognition, and the puzzle is well built around it. Wrong guesses cost you, so the goal is the shortest viable chain rather than any chain, and the interesting decisions are at the points where two routes diverge — going north through a handful of large countries or south through many small ones. The feedback tells you whether a guess is on a valid route, which makes recovery possible without giving the answer. It is a daily puzzle, shared by everybody, taking a few minutes. It also teaches efficiently: getting a route wrong and seeing the correct adjacency is how borders actually get learned. It works on a phone, needs no account, and is one of the better geography puzzles available because it asks a question the genre usually does not.
