How can I search for a Clash Royale player ID?

To search for a Clash Royale player ID, one must access the game on their mobile device or tablet. Once the game is open, navigate to the 'Social' tab and tap on the 'Friends' section located at the bottom of the screen. Here, there is an option to add friends. By clicking on this option, one can enter a player's unique ID or in-game name into the search bar. If one is searching for their own Player ID, they should click on their profile icon in the top left corner of the main game screen; the player ID is displayed below the username and experience level. It's important to note that IDs are case-sensitive and include both letters and numbers, so they must be entered accurately for a successful search.
