I'm not receiving my purple hearts.

Hello and welcome to the sweet King community.

Please can you attach a screenshot showing the error you mention?

Maybe this happens because you do not have the event, the functions and temporary events of the King games are test features that the Studio throws to groups of players randomly. That means they are not always available and not for all players.

I will wait for your answer to know if there are any errors.

Thanks and keep enjoying

My purple hearts are not registering. I don't even have a leader board.

It keeps inviting me to play the event every time I log in on FB. I've got the event and leaderboard on Windows 10.
