The Curious Mystery of the Map in Pokémon Go

Early on Friday evening, hanging out at a bar with friends, Boon Sheridan downloaded Pokémon Go, the new augmented-reality iOS and Android game. Pokémon Go forces players to wander through the physical world around them--streets, parks, and public spaces--to catch Pokémon. Players can also assemble near certain structures, like churches and pieces of public art, to battle their Pokémon against computer players at "gyms." Sheridan is a designer living in Holyoke, Massachusetts. Being of sound heart and mind, he quickly caught a Squirtle.
