Lets make a guess,
I dont think it will be something like wagering promotion. It could be something related to the upcoming Easter. So maybe those who have verified email in their account will get some easter gift.
Surely it is just a guess, but I hope it will be free promotion or a contest which is not a wagering contest I really miss their past promotion "bingo" which was managed by ndnhc long time ago.

We have a bit of intel for you guys... there is a Primedice promotion coming soon 😉
Make sure your email is verified to be involved!
