None of the changes of Primedice comes with any announcement. At first, they discontinued the VIP challenges on the forum, then the discontinued the regular challenges after a few months. Eventually, they had closed the Primedice forum. Now the Jackpot has been disabled as well. The only good thing is the readable chat messages on Primedice with a small number of active users .

I think they will spend the money on Stake Birthday, which is on the next month . BTW, they run challenges on their telegram channel (Primedice - Creators of Dicing) regularly.
