Currently, players are not allowed into battles when Ping is above 150MS, this is to ensure the best gameplay experience possible. You can see your current latency (measured in milliseconds) on the top right of the in-game home screen.
High Ping might happen due to:
1- Unstable internet connection
2- You are in the regions that are too far from our main current Server Centers: Asia/KR/EU/US/SA
You can use VPN for a better experience in our game, but keep in mind this won't make any great impact.
