guys i've tested 999dice.com in many ways.
999dice is a scam. dont waste your coins in that site. you will only lose your coins in 999dice.
99% users of 999dice.com are in loss.
I used to play there long time back and myself felt that there is something sketchy. I used to win all small bets and used to lose all big bets.
Maybe only luck but I decided not to play there anymore, after Stunna's accusation I would suggest stop using that site.
Boycott 999Dice
Though we dont have any proofs but still.. we can just boycott that site
