How to play Pokemon Go

Pokemon Go mania has players armed with smartphones hunting streets, parks, rivers, landmarks and other sites to capture monsters and gather supplies.

The free app, based on a Nintendo title that debuted 20 years ago, has been adapted to the mobile internet age by Niantic Labs, a company spun out of Google last year.

Pokemon Go uses smartphone satellite location, graphics and camera capabilities to overlay cartoon monsters on real world settings, challenging players to capture and train the creatures for battles.
