make it like a contest with different prize distribution. Lets say roll hunt for a specific number, players who roll it the most during the competition wins. This will make players keep on betting to hunt the number, unlike the previous roll hunt contest where players stop betting once they got the requirement.
If you join their telegram and twitter.
They make a lot giveaway everyday around 50-100$ for a few user, also they make a tournament Fight the Emperor every weeks on telegram group. That's why, I recommended all people to join their group or follow their social media to get some free balance from their giveaway or tournament.
Its all free.
I joined it yesterday as there was someone mentioned it on chat. Frankly speaking I dont like the Fight The Emperor game so I wont participate on it even if it is a free tournament. I'm hoping for more promotions for the dice game or blackjack or even the sportsbetting. I'll wait for the next dice tournament as they said that there will be new promotion once the new dice is released.
