with no guessing? wow! I'm actually thinking whether it's necessary to specify that green cells don't contain borderless countries. Not sure why stats disappeared: I added some hint columns and it's now working, must be some property inherited by copying from some previous quiz. thanks!
whoops!! I removed the "In the grid no country is adjacent to a bordering country, not even diagonally" hint as I think it's not necessary although it does make the quiz harder. I hope I haven't made any other mistakes! thanks a lot
Great quiz Scambigol. Can you write down your straight solution without cheating? It seems to me that time is not enough if you have to think of all the possibilities
ok I tried, taking the quiz a long time after creating it... maybe now that Macedonia changed its name to North Macedonia there's other solutions, I am not sure.
I hope this is correct and I am guessing it can be improved:
F4 - Togo (only 4 letter country alphabetically after Russia)
F5 - Yemen (only 5 letter country alphabetically after Togo)
so we know row C has A-E-I-O countries (in case Y was considered a vowel)
C4 - Oman
E4 - Mali (only 4 letter country with capital alphabetically before Bangkok other than Iraq)
Emw - UAE (only multiword country with capital alphabetically before Bangkok)
Fmw - Vatican City (only multiword beginning with V)
C5 - Italy (only neighbour of Vatican so must be in the quiz)
E5 - Ghana (only 5 letter country with capital alphabetically before Bangkok other than Samoa that has no neighbours)
A4 - Peru (only 4 letter country left alphabetically after Myanmar)
C68 - Angola (there's no 4-5-8 letter countries, Antigua and Barbuda has no neighbours)
D4 - Chad (other 4 letter option with borders is Laos, but having capital Vientiane it would give Cameroon as only option to its left; this would leave Laos without neighbours)
Cmw - El Salvador (the other multi-word E option was Equatorial Guinea but its neigbhours have C-G initials which are taken already) with Honduras as neighbour, somewhere in the first column
E68 - Jordan (other options with available letters are Brunei but can't have Malaysia, Greece but can't have Albania, Macedonia - actually now it's North Macedonia you could... - or Turkey)
This means S is Jordan's neighbour (can't have Israel or Iraq) either Syria or Saudi Arabia (in case Qatar has 'dubious' neighbour UAE).
F68 - Rwanda
This mean DRC is in the quiz as Rwanda's neighbour (Burundi is 7 letters long, U for Uganda is taken, T for Tanzania is taken)
Emw - DRC (if you look at possible multi-word countries with borders and possibile initial letters having capital alphabetically before N'Djamena, it's the only option - remebering to consider that S is taken as Jordan's neighbour)
B4 - Laos (only L countries possible are Libya but no cell is good for it because of row indications or green cell as it borders Chad; and Latvia but no neighbour can be present)
D68 - France: the only F country that can find a place; can't be in row A because alphabetically before Myanmar, cannot be in row B because capital is shorter than Vientiane
B68 - Honduras: only possible place for El Salvador's only possible neighbour
We have 6 letters missing: B K N Q S Z
Z is definitely taking the only 6-8 letters box left. K and Q are taking 2 of the 5 letter boxes as they have no multi-word answers.
N has North Korea and North Macedonia possibilities (well it didn't have North Macedonia when the quiz was created) but they have no possible neighbours in the quiz, so it's either Nepal or Niger. That leaves S and B as multi-word answers.
B5 - Kenya: only place for 5 letter long country not bordering other countries in the quiz
D5 - Qatar: Doha is as long as Lima so Qatar can't go in A5, this means D5 is the only option
A5 - Niger: Nepal has no neighbours in the quiz so it's the only option
Bmw - Burkina Faso: Bosnia has no neighbours in the quiz, Burkina is alphabetically before Myanmar so this is the only option
A68 - Zambia: as Zimbabwe has no neighbours in the quiz
Burkina Faso and Niger do share a border and are adjacent, though.
I solved it using the old green-cells-dont-contain-borderless-countries-hint from the comments.
