This summarizes a logic puzzle where the goal is to arrange 29 countries in order to circumnavigate the globe starting and ending in the same country, with only two direct ocean crossings. Clues are provided about characteristics of the countries in each box that must be used to deduce the order. Key details that are provided include borders between countries, geographic locations, language characteristics, and place names within country names that help narrow down the options.

Circumnavigate the globe, starting and ending in the same
country, visiting 29 countries in total. But for one Atlantic
& one Pacific crossing (both nonstop), you could do the
rest of the journey on foot.
Having Google Maps open (or an atlas to hand) would be
very useful to help with this logic game.

2. Clue 1: Following the numbers, each country borders the next (but for 2
direct ocean crossings.) This means that Box 2 must be SPAIN.
Clue 2: The country with the highest number of Portuguese speakers is
BRAZIL, so this must be in Box 29.

3. Clue 29: No country in column A begins with a vowel, so this rules out Andorra (and
UK) as possibles for Box 2. Morocco is possible, until we consider that the Atlantic has
already been crossed between 29 and 30, so the only remaining possibility is FRANCE.
Clue 3: Box 5 contains a doubly-landlocked country. There are only 2 of these, i.e.
Liechtenstein and Uzbekistan, and only one of these can be reached from France by
crossing one country, meaning Box 5 must be LIECHTENSTEIN. The only way to get to
Liechtenstein by land is via SWITZERLAND or AUSTRIA. Clue 30 tells us that there is to
be no westerly travel, so Box 4 must be the former and box 6 must be the latter.

4. Clue 6: The only country bordering Austria whose flag can be made by
changing the colour of one stripe is HUNGARY, so this is in Box 7.
Clue 7: The country in Box 13 contains a 3-letter string that can be found in
‘France’ and can be spelt using the letters of ‘Switzerland’. The only country
to which this applies is IRAN, so this is in Box 13.
Clues 4 + 5: We know that the country in Box 8 also contains the letters I, R, A
and N, but is not Romania. The only country bordering Hungary which this
leaves is UKRAINE, so this is in Box 8.

5. Clue 5: No ‘K’ countries are in the quiz, so the only possible easterly route which can
get us from Ukraine to Iran (avoiding Kazakhstan) takes us via
RUSSIA, GEORGIA, ARMENIA and AZERBAIJAN, which will therefore be in boxes 9 to
12.
Clue 4: The country in Box 14 borders Iran and has the letters I, R, A and N in it. As
Azerbaijan has already been passed en route, this means that Box 14 must be
TURKMENISTAN.

6. Clue 8: A country in the third row ends in ‘U’. The only non-island nation to the east of
Ukraine to which this applies is PERU, so, as this borders Brazil, with not enough other
countries to its east to be feasible en route, it must be in Box 28.
Clue 28: Azerbaijan and UZBEKISTAN are the countries with Z as their second letter, so
the latter must be in Box 15.
Clue 10: The world’s first country alphabetically is AFGHANISTAN. As this borders
Uzbekistan, and is in the same row as Armenia, it must logically be in box 16.

7. Clue 16: China is visited at some point after India, so it cannot be in Box 17.
Going east from Afghanistan, this only leaves PAKISTAN as an option en route to
India, so this must be in Box 17. The entire eastern border of Pakistan is taken
up by India and we have already visited Afghanistan, so INDIA is the only
possibility for Box 18.
Clue 18: The capital of the country in Box 19 begins with an ‘N’, so this can only
be MYANMAR.

8. Clue 17: If two countries in this column are landlocked and there is only one
remaining, this must be LAOS (Box 20).
Clue 20: All but one of the letters in Box 21’s country can be found in
‘Vientiane’. This must mean that Box 21 is VIETNAM.

9. Clue 16: We already know that CHINA is visited and this is the only country that both
shares a border with and lies to the east of Vietnam, so the former must be in Box 22.
Clue 22: There are no countries with 5 stars on their flag that share a land border with
China, so this must be the point at which the Pacific Ocean is crossed. The only country
on the eastern side of the Pacific rim with 5 stars on its flag is HONDURAS, so this is in
Box 23.

10. The remaining route is the only possible one to get from Honduras to
Peru, travelling only by land and bridges, so Boxes 24 – 27 can only be
NICARAGUA, COSTA RICA, PANAMA and COLOMBIA respectively.
