Don't worry — here's how to get back in the game.
Every level, streak and finished course earns a certificate. Your first one is closer than you think.
Invite as many people as you like — every friend who joins through your link earns you 50 hearts.
You haven't earned any free hearts yet — share the link with friends to start getting rewarded.
Share your unique referral link with friends and family. When they register through your link, you'll receive 50 hearts as a reward. Unlike the hearts you receive daily, referral hearts are single-use and are stored permanently on your device. Once used, they disappear.
An invalid click occurs when someone clicks on your unique referral link but does not qualify for the referral program because they have already been referred by someone else, are using a VPN, or are operating an unsupported browser. Referrals deemed invalid will not earn you any hearts.
