July 13 2016:  Pokemon, the Japanese game that  was first launched by its Japanese creators in the 1980s,  is seeing a sensational  re incarnation since its US launch earlier this week.   However the app is  not downloadable in India --yet

 With Pokémon GO, you’ll discover Pokémon in a whole new world—your own! Pokémon GO is built on Niantic’s Real World Gaming Platform and will use real locations to encourage players to search far and wide in the real world to discover Pokémon. Pokémon GO allows you to find and catch more than a hundred species of Pokémon as you explore your surroundings.
The Pokémon video game series has used real-world locations such as the Hokkaido and Kanto regions of Japan, New York, and Paris as inspiration for the fantasy settings in which its games take place. 
This is how it works now, with augmented reality thrown in:
Get on your feet and step outside to find and catch wild Pokémon. Explore cities and towns around where you live and even around the globe to capture as many Pokémon as you can. As you move around, your smartphone will vibrate to let you know you're near a Pokémon. Once you've encountered a Pokémon, take aim on your smartphone's touch screen and throw a Poké Ball to catch it. Be careful when you try to catch it, or it might run away! Also look for PokéStops located at interesting places, such as public art installations, historical markers, and monuments, where you can collect more Poké Balls and other items.
Pokémon GO is available for download at no charge on the App Store and Google Play. Pokémon GO is free to play, with loads of fun things to do and Pokémon to discover at every turn. For players who want to enhance their Pokémon GO experience even more, certain items and features can be accessed via in-app purchases. Players can spend real money on PokéCoins, the in-game currency of Pokémon GO. PokéCoins can then be exchanged for power-ups, extra items, and other enhancements.
