This is how you get free Poke Balls in Pokemon Go without spending
money on PokeCoins. On the world map, you’ll see floating blue diamonds
scattered about. These are PokeStops! You’ll need to physically walk to
these PokeStops, and when you’re in range the blue diamonds will change
into circular icons, signifying you can interact with them. Tap and
you’ll see a real picture of the location, otherwise known as a Photo
Disc.
Spin the Photo Disc with your finger to get free Poke Balls and
other items, like Pokemon Candy used to Power Up you Pokemon.
You only receive a limited amount of items from PokeStops with each
trip. To get more, you’ll need to come back later. We don’t have an
exact amount of time, but you should be able to return to a PokeStop at
least 10-15 minutes later, based on our experience with the game.
Pokemon Go Tip: Always be aware of your surroundings when playing
Pokemon Go. Make sure to look both ways before crossing the street, and
watch out for people on the sidewalk. It’s easy to get distracted while
walking and looking at the phone screen.
