Poké Balls are items that are critical to a Trainer's quest, used for catching and storing Pokémon. Currently Poké Balls can be obtained through several different ways such as: spinning Photo Discs at Gyms and PokéStops, being rewarded for leveling up, completing research tasks, opening gifts or purchasing them in Shop (in this case only regular ones).
There currently five varieties of Poké Balls exist in-game:
- regular Poké Ball,
- Great Ball,
- Ultra Ball,
- currently not-available Master Ball
- and Premier Ball which is available only in Bonus Challenge on Raids or Team GO Rocket.
Regular Poké Balls are the most common and have the lowest success rate in term of capture. The rate increases with the Great Ball, and above.
To see currently owned Poké Balls player can check them out on the item bag page .
When encountering a Pokémon in the wild, players can attempt to catch a Pokémon by holding down on the Poké Ball, sliding upwards, and letting go to launch it towards the Pokémon.
Players can influence bonuses on catching Pokémon by aiming the ball towards the center of the Pokémon while letting the circle indicator shrink down. The closer the ball is to the center, the better bonus you'll get. Players can also hold down the ball and spin it for a curveball bonus that grants additional experience. Selecting a better type of Poké Ball will make the Pokémon easier to capture.
