To invite friends to play, tap on the Profile icon in the footer of the screen. You’ll see your personal invite link, which you can share directly from the app or copy to your clipboard and paste anywhere you like.
When someone clicks on your invite link and installs the game right after clicking, they’ll be attributed to you as a user who came through your invite link and become part of your network.
To view the users you’ve invited, tap on the Shield icon in the footer. This will display your network of users who have joined the game through your invitation.
