Still no one hit the jackpot since PD add it few years ago or are there some jackpot winners already? ~
No one has claimed the jackpot yet, but some users got the jackpot number. But most of them wasn't eligible for the jackpot prize for the min bet requirement. There are several topics in Primedice forum, where the users asked similar question like you. This is one of those topics:
Has anyone even won the jackpot now ?Here is the reply from a moderator of Primedice in that topic
I have hit 77.77 twice in a row 5 times already. But all of my bets were with zero or few satoshis, so i was not eligible for the jackpot. Statistically it is bound to happen once every 100 million rolls, so theoretically we have had already ~317 hits like this. Most of them probably with low bets or by people who didn't even see that they hit it
I also check them only once per a few months as i store all my bets, but i would probably miss them all if i didn't use any bots for it...
I think Primedice should change their jackpot winning system. This isn't so easy to roll 77.77 twice. There is some min bet limit. Moreover, the system isn't automated. User needs to contact the support team if he/she is eligible (meet the requirements) for the jackpot.
