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?


Egypt
Argentina
Australia
Botswana
Brazil
China
X
China


One 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.
