[...] will talk more with the devs in an attempt to fix this as it is a known problem that the verification page on their site is in need of a serious redo.

The verification script on PD was fixed several days ago now. You just need to re-copy it into your verifier.

Thank you OP, I will be sure to stay away from this scam company and suggest everyone else to do so as well.

Except OP has been discredited. The rolls are fair, and provably so.

If the site was using different algorithm than the shown one, I called it cheating, at least not 100% fair.

What if it is "slightly outdated" again? It's totally unfair to every player.

Again to repeat myself to ensure no one feels cheated by:

The code we provided on our verification page was slightly outdated as we changed the privably fair system to use less data. That is all.

All bets however DO ADD UP perfectly fine if you modify the script to the correct one.

Any reputable person (Dooglus etc.) who has a sound understanding on provably fairness can verify this. No one had rolls manipulated.

It's your responsibility to make sure that verification is correct. Now I use that script to verify, and  you say it's slightly outdated.

Tell me what's the purpose of this verification if the site is not using it and whenever someone points it out and then it's "slightly outdated".
Who knows what exact algorithm you are using behind the door?

What would it happen if someone else finds an other problem, and it will be another "slightly outdated" or another excuse?
 

I am paid? Which unfairness I found are not true, including that PVP feature?

Want 100% provable fair? Do act like one.
So do you job and make sure it's 100% fair.   And not when someone points out a problem, and you throw out thousands of excuses.

How can you say your site is 100% fair and even provides a script for everyone to verify. After someone finds that you site is cheating by using different algorithm, you say it's lack of documentation.
So what's the purpose of the verification which can't verify the result? 
During 3 days I was using PD, I found 2 unfairness. And the site seems they are totally OK. I know it's ok for you because you are the one cheating.
And you think I would expect you to return my stolen bitcion?  I would not, because you site is a totally scam site.


can you post the proof of your findings, so that people can see it also?

Primedice is cheating

Yesterday I was just using PD to bet and doing the double-or-nothing experiments.
It was going fine at first. But suddenly, I had 11 consecutive-losing bets.
They were pretty odd, weren't they?
So I did some verification using the script provided by Primedice.

See the screenshots below. I did verify all 11 bets. All 10 bets are correct, but the No.2 bet from top is wrong.
On the screenshot, the roll is 92.29. However, the result I got from script is 0.02.
So I should win that bet, there would not be the last one bet(top one) which cleared me out.

Please don't say that your verification script is not updated.
What's the purpose of the verification script that site does not use and can't verify result?
So whenever someone finds you are cheating, you can say it every time?

Return my money back, you scam site.

You can look up these bets by the bet id shown in the screenshot and verify them by yourself.
This did not just happen once but twice today and almost clear me out.
Since Primedice has been online for so long, I could not imagine how many times it has cheated.
I probably will do the same experiments on other bitcoin gambling web site. But Pirmedice is not trustworthy and return my bitcoin.

I also found the possible unfair when you PVP with "strangers" on Primedice.
See the post: https://bitcointalk.org/index.php?topic=733500.msg8315850#msg8315850

I only used PD for several days, and already found 2 unfairness. 
How  you can still claim yourself 100% "provable fair"?


The script I am using:

            //the seed pair itself
            var clientSeed = "ca45edd88ef251dd43edf42dc97c7ffb"; //dont forget to exclude the dash and the nonce!
            var serverSeed = "41fa224237f452360db8d35a276f4067fce6cad8d3dbf3c73bde2e804c8cb8c7";

            //bet made with seed pair (excluding current bet)
            var nonce      = 3391;

            //crypto lib for hmac function
            var crypto = require('crypto');

            var roll = function(key, text) {

                //create HMAC using server seed as key and client seed as message
                var hash = crypto.createHmac('sha512', key).update(text).digest('hex');

                var index = 0;

                var lucky = parseInt(hash.substring(index * 5, index + 5), 16);

                //keep grabbing characters from the hash while greater than
                while (lucky >= Math.pow(10, 6)) {
                    index++;
                    lucky = parseInt(hash.substring(index * 5, index + 5), 16);

                    //if we reach the end of the hash, just default to highest number
                    if (index + 5 == 128 + 1) {
                        lucky = 99.99;
                        break;
                    }
                }

                lucky %= Math.pow(10, 4);
                lucky /= Math.pow(10, 2);

                return lucky;
            }

If only verification documentation is wrong what it seems to be than i guess its not that bad situation ?

I don't know if it's that clear cut. If you launch a site with the documentation saying "we are provably fair because we do A, B, C to generate your rolls" but what you actually do is "A, B, D", then when the outcome of A, B, C and A, B, D differ, such that the player would have won if you did what you said you were going to do, but he loses because you actually do something different... then it seems like he has a winnable case there.

He took you at your word that you were doing A, B, C but it turned out you weren't doing that at all, and the difference caused him to lose.

I think dev has that already updated but as i said he wasn't online for whole day , he shoulda pushed some other updates today also .

I think the code snippet was updated recently. It was just updated wrongly, making it even worse than before since now it often computes very low rolls, like the 00.02 in the case that brought the error to light.

What is more important than the method of fairness or any algorithm is the fact that the roll was fair and the user got the exact win odds expected to win the bet which he did indeed.

I personally feel that your point about the "difference' causing him to lose is invalid, would he have adjusted his client seed etc knowing that the system used was different? This only seems to be important after the fact given that he lost.

I'm doing my best to provide a fair experience, I'm also working on code so I can be less reliant on developers to solve these sorts of issues. At the end of the day though his roll was fair and unmanipulated.


Also coinfist is a shill for another casino: https://bitcointalk.org/index.php?action=profile;u=365873;sa=showPosts  (Notice all his posts are him screaming that PD is a scam in all caps) I'm not refunding him 0.01 which he lost placing a 100% fair bet. He literally created his forum account to simply type anti PD posts. Instead of proving that the verification section text  was incorrect you should instead try and prove that he did not get a 100% fair bet.


Also with regards to the 37,500 bet situation, I've already compensated the guy who should have won the 9900x payout 1 coin and will see if it is possible to run some sort of query for anyone who made this bet. In this situation the site was documented 100% correctly, just the house edge was advertised as 1% not 1.01% on old PD incorrectly.


Primedice is 100% fair but our verification page text has mistakes on it and is inaccurate end of discussion. We will edit this page today (hopefully without error this time)

How can you say your site is 100% fair and even provides a script for everyone to verify. After someone finds that you site is cheating by using different algorithm, you say it's lack of documentation.
So what's the purpose of the verification which can't verify the result?

And you think I would expect you to return my stolen bitcion?  I would not, because you site is a totally scam site.

I think nobody is blind here, we can read normal font just fine.

As for pvp, if u implaying that they will scam players with it, by betting against them and win all the time, that is so funny. Pd was around for ages , Stunna and pd never scammed nobody. If they wanted to profit on pvp they could done it in so many different ways, one that involves dev sitting on pvp all day beating other people is just not one of them . Cheesy .
And that wouldn't work for so many reasons.



If you have nothing to hide, why are you so upset with the font and color. You should feel lucky I posted here and not in your main thread.
And I am not implying anything. I just saw the web site says it's 100% provable fair. And I just found something that's unfair.
If PD says it's 99% fair. I am OK with that and there won't be this post.

I believe dev is smart enough to write a program to play users. If your dev doesn't know, let me show him. Shocked Shocked Shocked Shocked

PVP does not seem to be fair.

Let's say, one user challenges another user who "happens" to be web site, primedice.com.
Since web site knows challenger's seed, he definitely knows the next roll number.
So web site can cheat on users, manipulate games and win any games he wants, especially those big bets.

Explain to me if I am wrong.


There is no profit made by PD on PVP games, so why is PD is so stupid to make it so call "not fair" ?     Grin


By cheating on PVP game, PD does not make profit by house edge.
They can direct win your bitcoins. That's called "NOT FAIR". So that's why house edge is ZERO.
I hope I can get an answer here.


how PD win make the profit when I PVP with someone i know which has NO relation to PD?
actually i also dont know why i was replying to this retarded question.. make me a retard as well ...

You only play PVP only with someone you know? I don't think it's the case that PD wants.
I don't think it's me who make you retard. Please go back home and ask your mother about what happen that night.
