When you’re in position to catch a Pokémon, the screen will switch to a first-person view with the Pokémon in front of you. Use your touch screen to throw Poké Balls to try to catch the Pokémon. Careful—Pokémon will sometimes move around, making it tricky to catch them!
Several factors affect your chances of catching a Pokémon. The Pokémon’s CP level, the type of Poké Ball you used, your throwing technique, and other factors come into play when determining whether the Pokémon can be successfully caught. And some Pokémon will run away!
