I'm talking about the provably fair part since they've been doing it with bustadice, it's kind of like a multi sig where it's divided to three parties. Here's a quote from bustadice's thread explaining the whole thing.
Enhanced provable fairness
bustadice builds upon conventional provably fair systems to provide additional guarantees to players, investors and the casino itself:
For players: If a dispute over fairness arises with a legacy casino, it's largely their word against yours. In bustadice, on the other hand, all bets are committed to an independent audit server in real-time and can be reviewed and verified by Ryan if need be.
For investors: Neither I nor Ryan can undetectably cheat by predicting future rolls. Assuming you trust the two not to collude, investing becomes provably fair.
In addition, the casino itself gains increased confidence that all wins are legitimateeven if the game server were to be compromised.
The way we do achieve is by introducing a third party: The auditor (Ryan). Final roll results are computed with input from all three parties: The player, the game server and the auditor. When a server seed is revealed, both the player and the auditor can verify its bets.
That definitely sounds like one of the working solutions to the problem of not so provable fairness. Another proof of unnecessity and uselessness of third party controls, all problems can be solved within a particular casino. Nonetheless, some problems still exist, for example, necessity of trust to people controlling game server and audit server, they still can collude and change some bets results. There is no problem I guess when casino is reputable, they are long enough in gambling business and likely won't cheat, although I can't be so sure in case of fresh casinos.
