If your account is linked to Facebook, you can invite your friends by going to Menu > Friends and searching for them in the search engine. By clicking on their name and accessing their profile, you will see the option "Play" to invite them to a new game in the Classic game mode.
You can also do it by going to Menu > Facebook > Invite friends.
Remember that you can also invite friends who are not in the game via link through different social applications. To do this, follow these steps:
- Press the "Send link" button that you will see in the lower left corner of your screen, along with your current games.
- Once you do, different social applications will be displayed through which you can invite your friend to the game.
- Once your friend receives and accepts the invitation, they will appear as a friend available to play every time you want to start a new game.
