In the augmented reality mobile game Pokmon Go, players use Pok Balls to capture wild Pokmon. As such, having an ample supply of Pok Balls is essential for successful gameplay. There are several methods for acquiring more Pok Balls in Pokmon Go, including visiting PokStops, leveling up, and completing research tasks.
PokStops are found all over the world and are marked on the game map by blue cubes. When you visit a PokStop, you can spin the Photo Disc to receive items, including Pok Balls. PokStops also periodically spawn Lure Modules, which attract wild Pokmon and increase the chances of getting more Pok Balls.
