I tried explaining this in the notes but it's probably not very clear.
You're allowed to type-in Uzbekistan instead of Tajikistan-Kyrgyzstan-Kazakhstan because in all 3 cases:
- the number of letters is the same (10)
- you could go to Uzbekistan instead, and still have a chance of finishing the 'walk' without having to repeat borders
Actually I guess I should have worked out a path that minimizes ambiguity, so I'll probably change it so that from Afghanistan it goes to Uzbekistan!
the spelling of kazachstan and kyrgystan did me in, would be nice if you could include some alternative spellings (from the world quiz for example)
