Mate, the site you mentioned is dicecoingames,why did you suddenly told us about 999dice? Are both sites same or owned by same person? Afaik 999dice doesn't has any minimum deposit.
This site seems to be getting shadier by the minute. Its design is pretty bad and it is missing a FAQ section (There is a common section with a single question). I don't recommend investing anything here at the moment.
I already said that as statistics were wrong and they were tidy, when you play on the site, you win, make a withdrawal and do not receive the money then you come here to say if it is a scam or not.
The statistics have been tampered with multiple times now which is really fishy. How can they be incorrect multiple times op? Care to clarify?
