Yes, they publish everything on their website and this does allow to verify actual bets, however I found something interesting.
是的，他们在他们网站公布了所有可以用于验证实际投注公平性的信息，然而，我却发现一些有趣的事实。We have three variables: secret, server seed, client seed. The client seed can be changed, however most don't bother to do it, and I believe this allows(and may even be exploited by the owners already) to do selective hashes.
我们有三个变量：密钥，服务器端种子，客户端种子。客户端种子可以被改变，当然很多用户懒得去操作。这使我相信玩家有自由选择权（有些过分的网站还禁止了这个功能）。Basically, the secret seed is a constant for 24hrs, the server seed is pre-generated before your next bet, it's the server seed that is the "weak" link. Basically they assume that the client seed WILL not be changed for the next bet based on user activity and then they pre-generate server seeds and select only those that would later hash to lower bets than your avg roll over number which is how they don't need to know what you are betting to roll over.
基本上，密钥是一个固定字符串，维持24小时不变。服务器端种子在您下一次投注前自动生成，而这个正是这个系统的软肋。基本上，（后边这段，后置定语太多了，我尝试翻译，高手回帖更正，也是他要表达的重点），他们根据用户之前的操作，估算你不会改变客户端种子，然后自动生成服务器端种子。然后设置使你们的中奖率低于随机中奖率，这样他们就没有必要知道你在玩那种赔率游戏了（这样你怎么都会输）。
Nov 8 update
11月8日 更新Even with their new layout, and "nonce", the server seed is still being used. If you can change the nonce every single bet to a random one, you can fix the problem, but the better solution yet would be for Stunna to remove the server seed entirely.
即使是目前最新的架构服务器端种子也被使用，即使使用硬随机数。如果你每次投注都改变硬随机数，你就能解决这个公平问题。但对于Stunna（估计是prime的老板）更好的解决方案是彻底取消服务器端种子。 原文链接：
