hello,
I would like to know more about the jackpot in primedice. Is it two 77.77 consecutively or in a row?
You need to roll 77.77 twice in a row (two times 77.77 one after another). The odds of this are 1/100,000,000.
I have never seen 2 identical roll number in a row, but since it is something added by primedice which has been trusted forever, one day we'll see that lucky roller take that jackpot home.

I've gotten a two numbers in a row a few times - it's not the rarest occurrence if you're not looking for a specific number.
But exactly 77.77, twice...now that's rare!
Make this jackpot system automatic will be appreciated or if it's too hard to do, atleast give users an alert when they rolled the first 77.77. So, they won't miss this good opportunity.
This is a wonderful idea in my opinion,
Like a delay or a sound when you roll 77.77
To make it more specific, in slots, it is like when you need 3 of an image to be able to trigger free spins and you are able to make 2 already.
I am very sorry but that is the best explanation I can give right now.
