For those still not familiar with it, the free game displays virtual Pokemon on a map of the real world, powered by real-time geospatial technologies and Google's map data. Users interact with both real and virtual objects depicted in the physical world to search for possible locations of collectible monsters.
Your job then is to catch the critters -- you see them in the real world, using your phone's camera -- and battle them against others in nearby "gyms".
According to data by mobile application market researcher Survey Monkey Intelligence, Pokemon Go became one of the most popular mobile games in the U.S., attracting over 21 million peak daily active users as of Tuesday, only six days after its July 6 release.
Even in countries like Japan, Canada, Costa Rica and the Netherlands, where Pokemon Go has not been officially introduced, Android smartphone users are downloading the application from detour websites.
