There lots of gambling website where you can play with your money if you want to play with 0 deposit and dice game i prefered primedice.com number dice game ever where you can talk to support when you need assistance and other questions.
Support really matters especially for big rollers.
to O.P.
I would recommend primedice and bitsler if you are looking for the most visited, most played dice site. The latter not only have dice game but 3 others games to choose from and 1 more to be available very soon.
