To invite friends from Facebook, Twitter or send an invitation link to someone, you need to open your game profile and then click on the green button at the very bottom. Then you will see the possible options at the top of the screen.
If you click on the “Share” button on the left, you will see a drop-down menu from which you will be able to choose between the social platforms that you have installed on your phone. You will be able to share the link as a post or send it as a message to your friends. When someone opens the link, he/she will be redirected to the registration page of Euchre.COM.

If you choose the Facebook button on the right, you will see a new screen where you will be able to choose these Facebook friends to whom you want to send an invitation. They will receive a notification from which they have to register in the game.
