Primedice is the best i always win its help my personal needs.
They were very good but lately too many issues with the new PD version and if there are any issues its very slow to get support on. Plus I am getting always lag issues on that website. However the happy hour and their faucet sure is nice.
Actually i heard many issue regarding to that but i don't see any clear evidence that theirs truly an existinh problem regarding to their site, and if you think pd got a problem well you should find another better site before them, their are so many good sites for now wich we can play the same game and the same odds and its up to us if we will gonna like their designs and features upon playing at them.
