If they show the hashed seed before you bet, and the process using the server seed (provided afterward) and your client seed results in the output along with their server seed hashing into the hashed seed then it's perfectly verifiable.

Suppose my server seed is X and the result of it and your client seed would be tails (in a head/tails game).

I then hash the seed with SHA-256 and show it to you publicly. After you bet I reveal the server seed and boom: you can verify everything since I can't lie about the hash.

Please correct me if I have made an error in any way.

You are correct, but my point is that: is the "hashed seed" they show you, really the seed used to run the game?

for example they can just generate a random hash seed (asdbfj891y23basd) and display it on their website but then actually, their game will use a different hash seed (138sdf71982789zcxz). then when you lose, they will of course show you the server seed which solves your seed. but in reality it is totally different.

The way I see it, the seed and hash they provide might be legit, but what I feel is a source for worry is that of some dice sites having to ask players to first click some tabs to be able to see the hash. That may well be a knock on the door to alert the occupant to tidy things up before letting the one at the door in and all the while he stays, every thing would be made to look straight. I think having the hash to stream along as the game is played, should be a more convincing way a site should show they are truly provably fair since their code is not open source.

This is the reason why people need to learn how provably fair works because many have no idea how it works exactly and always assume a casino can cheat but they don't understand that the rolls are already determined before the bet is taken place.

I don't think any casino would do what he suggested, showing one seed and using another because eventually someone would of caught on and complained, they don't know whether who or not actually verifies the seeds.

Correct! Since other people assume that good looking site are pretty much fair but if they look on the website seed if devs would share it you can actually see how was te state of their site will be.

But their are so many scam casino has been busted here since there are so many knowledgable gamblers knows on how provably fair system works.

Yes in general if you gamble only on the reputable bitcoin sites listed in the various threads on bitcointalk you are usually safe. Because if one user gets scammed, he usually is the first to open a complaint on the forum and others will investigate the issue and the site might lose gamblers.

However the problem is most people don't use bitcointalk. One reason is that its only English based and there are hundreds of languages around the world. Another reason is that its too much reading. So most people just google "bitcoin gambling sites" and go to those top 10 lists with affiliate links and gamble there. However those casinos aren't properly vetted and might be scams like they were in the past.
