Pikachu, where are you? That is on the minds of millions of people in the U.S. who downloaded the Pokemon Go smartphone app after it launched July 6. If you remember the Pokemon card trading game from the 1990s, you are probably familiar with Pikachu and some of the other animated characters. But now the cute monsters can be collected outdoors using your phone’s camera, map and location tracker. As gamers walk around their city or neighborhood, they can encounter and capture colorful characters. The characters are captured by throwing virtual balls into hoops near the character. Players can also look for landmarks around their city where they can collect more balls and other in-game rewards. Some of the landmarks are statues, museums, police stations and public transportation stations.
