As a player walks down the street they’ll see checkpoints where they can earn prizes and also catch little creatures called Pokemon. The game compels you to keep an eye on your phone as you walk along the street.

Despite debuting in the United States just last week, Pokemon Go is already leading players into trouble. In the St. Louis area several players have been robbed after thieves set up a beacon in the game to draw players to an isolated area.
