Hey, guys! This is still a major work-in-progress! Please bear with us, and help make this forum great!
This is a fan-run forum for the discussion of the Pokémon Go mobile game and the building of a Pokémon map.
As we all know, the number of footprints under each Pokémon on the Nearby List indicate their proximity. However, those with the three footprints (which are usually the coolest, rarest Pokémon, of course) are kind of hard to find.
Summarizing an article on Forbes (link at botom): The best way to find what you want is to open your Nearby List, and circle the desired Pokemon, but DO NOT close the list!!
The order of the Pokemon on the list further indicates proximity, reading from left to right and then down each line. So a Pokemon at the top left corner is closest to you, while one at the bottom right is farthest away, even if they all have three feet under them.
Keep an eye out as you walk, and if the desired Pokemon is moving closer to the top left position in the list, you're definitely getting closer!
Note: Contrary to popular belief, if the list pulses, it is because new Pokemon have been added to it, NOT because you are closer to your desired Pokemon.
