Dots will appear as you type Country Tripoints: can you list them all? They are listed by latitude, going from North to South
To guess a tripoint, type the first 3 letters of the three countries in any order. These are the first 3 letters of the standard JetPunk name, so for example you could type AUS-FRA-GER, FRA-GER-AUS etc for a hypthetical Austria-France-Germany tripoint. For some countries you are also allowed different letters (eg UK).
