Bordlr

Bordlr is a free browser geography game by shwrk, played at bordlr.com and on itch.io. Each puzzle shows two targets on a world map, for example Portugal and Vietnam, along with a par. Your job is to join them with a chain of regions that border each other.

You type any country that borders one of the two targets or a region already on your route, and accepted guesses light up on the map, so the chain can grow from both ends until they meet. Only real land borders count, plus three fixed crossings: the Oresund Bridge between Denmark and Sweden, the King Fahd Causeway between Bahrain and Saudi Arabia, and the Johor to Singapore causeway. There are no ferries and no ocean hops, which is why island nations never appear inside a chain.

Each solve earns up to 100 points for using as few regions as the shortest possible chain and up to 100 for matching the shortest real-world distance, measured between region centres, for a total out of 200. The two do not always agree: a route through a few large countries can cover more kilometres than one through several small ones.

The daily puzzle is numbered and the same for everyone. It changes at midnight local time, with world countries on most days and a US-states board every third day. A Weekly tab adds one more route each week, counted from Monday, and in our read it carried the coming Thursday's daily route early. Practice mode gives unlimited extra puzzles on either board. A hint shows a useful region without placing it and costs 10 points.

The results card lists your route beside the fewest-regions route and the shortest-distance route, so you can see where you lost points. Results can be shared as an emoji grid or an image, and a friend can be sent the same route as a challenge. Private leagues keep a table for a group with no account needed. The site also has country and US state border atlases and featured border paths for study. It suits people who like map trivia and want something more strategic than naming a single country.
