How to Add Friends on Hay Day Without Facebook

If You Know Their Tag Number

Open the Friend Book on your Friends and Followers Tab.

Look for a dialogue box with # key. Next to it is search option.

Have your friend do the same thing, so they can tell you their tag number.

Enter your friend's tag in your search field. Your friend's farm name will pop up.

Click 'Add as friend' next to their name.

Using the Game Center

Make sure you're both on the Apple version of the game. If you're both on iOS devices, you can also add your friend through the Game Center and include them in your Hay Day friends that way.

Open the Game Center app.

Click on "Friends".

Tap the "+" symbol to add a new friend.

Send your friend a friend request. Enter their email or nickname (if they're in your Contacts app), and an optional message. Once they accept your request to be Game Center friends, they'll be added to your Hay Day friends automatically.
