Rarely people verify their bets even if it is a won or lose because not everyone has that much patience after results, but here community helps them to keep updating about the status of their fairness level from time to time.This thread can be helpful for someone who wants to verify their bet on their own but lot of people claim legit fair casinos as scam because of their mistakes, particularly while verifying the seed, some of them forgot to copy the special characters which gives them invalid results.

The information and others (assuming they're all very reliable ) could also be guide to experience bettors who wish to spend some time and verify the provable fairness of most of the betting sites that claim "Provable fair". I think those with true/good provable fair feature should be trusted more than those without

Perhaps it's better to add a poll if gamblers are really checking or verifying their bets. I'm sure majority don't because they really on "trust".  As far as I know gambling sites are different in their Provably Fair implement, but the basic is what the OP has said, [serve seed:client seed:nonce]. I would agree that we shouldn't use the client seed generate by the gambling site, you should always choose your own and better change it for new bet.

I have seen a casino gambling sites before that also provide a provably fair calculator in their website as they front that their casino offers a provably fair games. While it's not important to those casinos who already built their name and to players who play in old top casinos, the new casino uses this factor atleast to be reviewed or test by some players, they put it to those people who really check fairness of the games even only few checks this it's still a factor for some gambling enthusiast or more in sake of review.

Hope to see them provide a guide to check the fairness too. I'm not seeing it very easy actaully. I have read some guide how to check but it took me hours to come up after folowing a very complex instruction and in the end its still not a guaranteed verified information since they can randomly change the things on the server side.

The only casino that we may be able to see its fairness are the Blockchain Powered Betting that using the tx like Casineos.com  Just plugging.  There are increasing number of casino that uses this Blockchain Powered Betting kind of fair system like the BETHASH.io

Different for each site, but the good ones will hopefully have the functions that you can fit your parameters (of server seed, nonce and client seed) into, to verify that the result on the site corresponded with the mathematical result.

The whole reason for using it is so that you can rigorously confirm the validity of each bet. If you're having trouble with that, isn't it a good idea to simply stop betting? After all, you wouldn't play craps with a pair of dice that someone decided to bring in on their own -- you would want to verify...

Don't trust, verify.

Checking each seed every bet on a newly-established casino is a good practice to check whether the casino is 'playing' with you, but for an established casino with millions of bets already placed on their name, I guess it will be an isolated case wherein there's a bug that causes the seed to not match the expected outcome. You'll probably be compensated AND rewarded by finding this bug, since the last thing that established and reputable casinos want to happen is users finding about that bug and causing a stir online, hurting their reputation. Points are valid and should be done on new casinos that want to have a name on the game.

I disagree with you the provably fair algorithm could just take the server seed and the client seed as parameters of a hmac function and eventually concatenate the nonce with the seeds before, like the way freebitcoin is doing. You don't need to concatenate the server seed and the client seed to get a provably fair gambling algorithm.

Code:

1. Two strings are created :
STRING1 = "[NONCE]:[SERVER SEED]:[NONCE]"
STRING2 = "[NONCE]:[CLIENT SEED]:[NONCE]"

2. Then HMAC-SHA512 is used to hash STRING1 with STRING2 as the secret key, giving us a 128 character hex string.

This is big illusion, the same as "open sourse code".  Overwhelming majority of users will never even try to check fairness of their bets just look at the "opportunity to do so" and will be fine with that. At least for the moment, where one (per thousand or more) user will check it and find it to be nor fair. 

This often happens in github, when everyone using some repo, for the moment when it happen to be some malware or something like that.

that is very true! i for one, rarely check the provable fairness of the site. because if you are playing on a respectable site, checking the fairness is out of question. but if you are in doubt about the legitimacy of the site, you can randomly check how provable fairness is working on their end.
 just like what you have given as example -  "open source code" projects. how many people are really looking and scrutinizing their code?

How am I just seeing this thread for the first time? I haven't posted here for a while but I felt compelled to after an internet search on provably fair sent me to this topic. This article referenced is the most honest and non-conformist explanation of provably fair I've ever seen. After reading it, the points made by the author seem very obvious but I was so brainwashed by the 1000s of identical definitions and explanations of provably fair across the forums and casinos that I just accepted that crypto casinos were being the fairest and most transparent they could be. Now I'm not so sure. I did a bit of research before commenting to see if any casinos have actually addressed these problems with their universally approved provably fair methods. The casino that owns the blog where this article is published is the only one, not surprisingly, that uses a different seed pair for each game. Why would this not be made a standard across all sites with provably fair games? It is the only way to guarantee that a casino doesn't push you away from an upcoming win on any game. I've only really checked a few sites. If anyone knows of other sites that have taken this same stance, let me know.......

That would be my honest reaction and reply to this article if I was not the one who wrote it. lol. Thanks for the shout-out. I am a rep for BC.Game but I am happy to say that they updated their provably fair implementation after I wrote this article in response to it. That is why I am still representing.
