In each cell you are shown on the initial letter of the country inside it. Each country touches horizontally, vertically or diagonally at least one country it borders on the world map.
Notes:
1) No country is more than 9 letters long 2) T is not in Africa 3) B is in Asia 4) The countries in the 4 corners have different name lengths, none of them is 4 letters long
hi, you can rule out all borderless island countries (so for example Haiti could be an answer, but you can rule it out once you see that H doesn't "border" D)
