How do I delete people from my friend list?
That depends on how you became friends in the first place:
1. If you want to remove an in-game friend (one you added in the Find friendstab or by using an invitation code) from your friend list, find that player in the Friendstab and tap X in the upper-left corner of the player’s picture.
2. If you want to remove friends from Facebook/GameCircle, first unfriend them in the respective social networks and restart the game. They will be removed from your friend list in the game automatically.
