I'm done arguing with this guy, it's a waste of time, i've already stated my points. Experience told me it's so hard to win in a dice game and in theory they do know your client seed if you don't change it every bet. If people want to play on this site, it's none of my business, just want to give those guys piece of advice and do think how many people are actually winning.
You're not done arguing, you never started. All you've done is stated your opinion and been unable to back it up with anything other than what you *think* happens. When I answered your concerns about us 'knowing' the client seed (we don't, we could only guess if you change it or not) you don't have any comeback.
You should have a think about this as well. If a provably fair site was to do what you say and use an algorithm that would mean that the servers seeds were not random. If they are not random then they would be predictable. Someone would work that out and be able to create client seeds to get the result they wanted, or even easier just bet low instead of high. Any provably fair site doing that would be cleaned out in a very short period of time. That doesn't apply to traditional fiat sites because they don't give you anything (server seed hash) in advance so they can just send you anything they want as the result after they have seen how you bet. If a provably fair site did that you would be able to prove you were cheated.
