How do I throw a Curveball?
On the Capture Screen (where you see the Pokémon and the Pokéball), you may throw a curveball by following the below steps:
- Place your finger on the Pokémon
- Move your finger around in a circle in either direction
- When you start to see the ball "sparkle," release it.
- Pray that the ball lands on your target.
The Pokéball will curve back in the same direction that it was spun, so spinning the ball counter-clockwise will result in the ball curving left. As a result, you want to aim right of the Pokémon.
This method requires some practice, but is rather easy after getting the hang of it.
If a curveball is successfully thrown, the catch bonus multiplier for the Pokémon increases by a factor of x1.7, making it as effective as a straight Excellent throw.
