To connect your Clash Royale game account, you must input your player tag. To find your player tag, open Clash Royale and click on your username in the top left corner. Your player tag should be visible in your Player Profile. Click on your player tag to copy it.
Make sure to complete training camp before connecting!
If you are having trouble connecting your player tag, please ensure that your player tag is accurate (some users accidentally mix up “O” and “0”).
