Read the hints:
• The first row shows the number of letters for each country, with some exceptions
• The first column shows the letter contained in the country name, with some exceptions
• The cell A4 is Chad.
• When you answer it, or a hint appears, or don't.
• Try to play in the order by column.
• No country repeats more than one time.
• If there's more than one option choose the rightern or leftern most country.
Am I being stupid - but I don't see how this works? Column five is supposed to be all European with one exception but it appears to have two exceptions. What does "three start with their letter" mean? Only one country in column six has six letters, despite cell 4n stating that two of them have.
