Right now I see that you still have the dice game and its provably fair but it is now from third party? or was it still your own dice game from before?
You can see the gambling provider below of the games,
of course it's from third party e.g. Orbital for classic games. The house edge is only 1% like the other casinos, so using third party isn't have any big difference with own casino games.
AFAIK, Orbital is the own game developer of FortuneJack casino. You shouldn't address dice game as third party providers game there. You may consider the games of 'orbital' as the in-house games of Fortunejack. Their dice game is same now as it was a few years ago.
FortuneJacks own game developing company, Orbital, took this mind-blowing and engaging game of luck to a whole other level, providing total control to the player.
