It’s more fun with Friends! You have 4 options to add Friends in your game:
Facebook Connect - if your game is Facebook connected, you can invite your Facebook Friends who are also playing the game.

If other players want to be your Friend, you can find them under the Request tab.
Suggested Friends - the game will give you the names of people you can add as Friends in the game.
