How to Use Master Balls
To use Master Balls in Pokémon GO, players must first encounter a Pokémon to catch by tapping on a Pokémon on the map, completing a raid or Max Battle, or as a reward from certain Research Tasks.
Tap the Poké Ball in the bottom right and select Master Ball. A confirmation screen will appear, forcing the trainer to confirm they really want to use the Master Ball.
Because Master Balls are a guaranteed catch, there's no Curveball Throw or target circle. Upon throwing the Master Ball, an animation sequence plays.
When to Use Your Master Ball
There are two primary use cases for the Master Ball in Pokémon GO.
- A Legendary or Ultra Beast raid encounter with perfect IVs.
- A Galarian bird encountered via
Daily Adventure Incense.
