Do you have questions about the principles of playing the game?
If you find something is missing, Charlie's Post Office can be found
here.
I am sending you each envelope in the game from a certain country.
You can look at the clues for each of the envelopes if you get stuck.
Which letter do I begin with?
ChinaOne person from 16 possibilities - not easy. Use the principle of exclusion to find person X.
The best friend of person X is in the row above. So we can exclude the whole top row, because there is no row above them…
Person X can only be the first person on the left in the second row. Now turn the letter over and you should know what to do next.
