Just a piece of advice, if you want to buy a fill-featured gambling site specifically with 'dice' then you must have a budget similar to what primedice have.
The OP seems not interested in buying anymore after he read all what was written here in this thread.
Agree, there's a lot of betting site that dice is the game. If he really wants to have a similar site with primedice, then he should invest more to have a decent and good gambling site.
note: He/She already found a gambling site that makes him/her interested.
The issue is not buying a dice game that is exactly similar to others, of course that comes with a marketing problem because why would anyone play at a primedice copy type place when the actual primedice exists but that is beyond the issues, that is what comes after he buys.
yeah, if I would create a gambling site, It should be more unique than everybody. I don't want to waste such thing if there's no good feature or benefits that will attract new investors.
