Most likely they are talking about the Weekly Draw. It was announced
here in the thread and on a
Medium post last December 2018. If you are curious about the details, you are free to visit the given links...
Thanks for this very fast and detailed answer. As always I am too late because Weekly Draw was planed only for 6 months and started in December 2018.
As long as they didn't announce an end date, the weekly draw continues. If you want to participate and willing to comply with the rules, you still have a chance.
