I don't think familiarity with Wordle helps much. This UI is pretty damn confusing. You type in country names, and then a km value, arrow, and percentage value appears. I have no idea what these signify. Clicking on the boxes brings up a box that gives you information but I have no idea how that information is relevant.
The arrow and distance are from the bad guess to what the answer actually is. So like I guessed Estonia, but the answer was Sweden so the arrow pointed northwest and the distance was some 300 odd km.
