The only available thing at Primedice but not available at Stake is the jackpot, but the jackpot is not attractive too because it does not work automatically (who is in this world will be willing to check their bet's number result one by one?)
Basically, it is possible to use Dicebot set-up to stop after getting a certain number twice in a row. The jackpot amount is attractive at Primedice, but not the overall rules.
I'm still surprised to see there are still few hundreds online users in average per day, are they what we can say as loyal users?
Yeah, those are some loyal user of Primedice. Although some of them are active in the chat to get free coins from rain. Still, a part of the old dice gambler like to play at Primedice.
