Pokemon GO is a video game app that combines the Pokemon world with augmented reality. The game is designed so that players have to actually go out into the world and find certain specific locations if they want to catch specific Pokemon, just like you would expect to be the case if Pokemon were actually real. The most recent version of the game has stripped away all the clutter of the original version while incorporating all the most memorable and iconic elements of the Pokemon library.
The game comes from Niantic, which produced a game called Ingress on which Pokemon GO is based. Ingress is another location based game, and Pokemon GO is based on that GPS-powered real-world overlay technology. In essence, you'll see a video game version of your surroundings as a top-view map, and you'll see elements on the map that you can travel to in order to interact with them. These could be Pokemon, gyms, or other special locations.
PokeStops are located all over the place, and they give you free items like Pokeballs and potions. Pokemon tend to be located in regions that match their elemental tag, so a water Pokemon is most likely found around a lake or beach.
