To do this, you’ll need to sign up with Zynga. You can also choose to play in separate games with your friends.
If you decline, however, they will be removed from your list and you can continue playing without them. If not, you can still send a friend request to them. If you accept, you’ll become the friend of that user. Then, you can decide whether to accept the invitation or decline it. If you’re planning to add friends on Zynga Poker, you’ll want to check your profile first.
