I remember I have played at FJ long ago. Haven't login and played there since so long. But recently while I tried to login I got this message “Your Account Was Suspended, Please Contact Customer Service For Further Correspondence”.
I have asked to the mail support and they replied me with this message,
This is to inform you that our system has flagged your account along with others, which is in direct violation of FortuneJack's Terms & Conditions. For this reason Security Department decided to close all associated accounts.

Can't realize that I have violated which part of Terms & Conditions. Is this the reason?

Well, I have made deposit and played there after registration. But might be I haven't login at the site for more than a year.
Can I get my account back or it is a permanent suspension? My username Mahdirakib at FJ.

Concern about Provably Fair Implementation on FortuneJack - Red Flag

I was thinking to create a new thread about this but I thought clearing here would be better before moving forward. So I am currently on a spree of checking Provably Fair Implementation on number of Crypto Casinos. Today, I was checking FortuneJack's implementation and there is clearly a flaw, a very big flaw actually.

Here's the screen where user can change client seed before placing bet:



You can see that the Server Seed (hashed) is = c94af6c5fcbebd0387485878a8edce6e80b1ce97c4f1daf165c63c48e40f94a6
Client Seed is = dbfombofbmofmbfoomd

Now I am changing the client seed:



Now I have set client seed to iamnowchangingtheclientseed
But here comes the catch, server seed is changed too!
New Server Seed (hashed) is bf795a8918921eec5c086029e2218469e58ae00eb1769f70318e54e9d8fd4529

If Casino is changing Server Seed after player has changed 'Client Seed' then there's a possibility that casino is manipulating the result. The whole purpose of Provably Fair system is ensure that Casino is not in power to change Server Seed after client seed is changed.

Looking for an explanation from FortuneJack representative on this.

To rectify the problem, all that FortuneJack needs to do is provide the to-be-generated server seed in hashed form before any user input. This makes sure that the casino side is not able to change the results in their favor reliably.

Exactly! This can be easily achieved by having two separate buttons to change 'Client Seed' and 'Server Seed'. If player wants to change the 'Client Seed', it shouldn't change the Server Seed too. Reveal the current Server Seed and generate new one only when player clicks 'Change Server Seed' button. That's how provably fair system should work.

Hey @Mahdirakib, we did review your case once again.

Unfortunately, there's nothing to be done on our end, as the account you've been using have been flagged for violating FJ's terms and conditions.

[slaman29]

User webtricks, thanks for highlighting this issue, shame you weren't part of the beta tester group when the new FJ dice 2.0 was being launched. Let's wait and see if there's a dev response to this, we wouldn't want a big part of FJ (provably fair) to be not optimized for PF now do we?

It could be a bug.  I'm not sure why FJ would cheat any of us and destroy their reputation, esp to a community as cynical and whiney as the BTC community.

Tbh I haven't seen a bunch of people so quick to call scam just cos there was a delay in their withdrawal.

It isn't a bug nor am I labelling FortuneJack as a 'scam'.

I'm currently in talk with FortuneJack representatives via PM and providing them more details. They will soon make announcement here.

It is possible but they should still give their own statement about that issue why that happened or is happening. To be clear to everyone and finish this issue immediately. Maybe many are waiting for their explanation about it. This casino has a reputation and it is also impossible to sometimes avoid having problems, whether it is technical or not. And even in other casinos, that really happens.

Fortunejack whats happen whith yuor hight odds on LIVE BASKETBALL ?
when i start betting here. that was ods like 1.95-1.95 for live NBA and other top basketball matches! after  change to 1.91 - 1.91  - its ok! it still good odds!
and now  1.83 - 1.83 !!!  for NBA Women
realy!?
why did you make it so low?

also before you had bonuses for those who bet on sports! now there is none of this !!!
I don't want to go to another bookmaker! but odds like 1.83 - 1.83 are worse than any bookmaker using same platform  (same like Betcoin.ag, Sportsbet.io, Playbetr.com) !!!
You are forcing me (and other users) to leave you and place bets with another bookmaker!

Can you get the odds back on basketball like it used to? well, or make them the same as those of your competitors?

Please answer - you are no longer interested in accepting sports bets? Are you planning to make normal odds, no lower than your competitors?

all I can say about the Fortunejack bookmaker is its very high reliability! I have never had any problems with payments, and I keep up to 0.8BTC on my account and am not afraid to lose them.

But, when I have a choice where to bet 1.83-1.83 (fortunjack) or 1.9 - 1.9 (betcoin.ag ) - my choice is obvious! If you don’t change it back as it was, then I (and other players) will have to go to another bookmaker !!!

please return as it was before or do the same as your competitors! I do not want to leave...

Updates on My Concern about Provably Fair Implementation

I have been talking to FortuneJack representative about the issue since yesterday in Personal Messages. However, I feel it would be better for everyone to understand the matter more precisely if I post everything in public before FortuneJack representative makes any announcement on the issue here.


Sequence 1: FortuneJack asked to me to provide more details about the issue so they can have better understanding on how the current system can manipulate the results.


Sequence 2: My Reply containing everything in detail:

In current implementation on FortuneJack, server seed changes too when player changes the client seed. This give undue advantage to Casino as casino is in clear control on what should be the result.

It won't directly give an advantage because player may bet over/under any number. But casino still has the following two advantages:

• 1. The default pair of seeds will be given to generate result 'over 50' since the default dice option is 'under 50'. If player changes the client seed before placing the bet, casino can still make sure to show the hash of server seed which when used with the new client seed still generates the result 'over 50'.
  
  
• 2. Casino can introduce a script to assess the player's behavior. For example, if player tends to bet 'under 50' most of the times then casino can show the server seeds accordingly and can make long term profits. This system is easy to implement too. If player set the client seed to 'myrandomclientseed'. Then it will take 0.03 seconds to generate a server seed with which the dice result will be 'over 50' in 55+ cases if player makes 100 bets. I just wrote a script and it generated me the result = '9775d8a4b21633daf29dbe2ea13a358702bb0bd7ada5c7d83958693b20d32751'.
  
  Now I just have to provide this seed as server seed and results will be in my favor in 56 cases out of 100 cases if players bets 'under 50' for 100 times.

The whole purpose of Provably Fair system is to make sure that Casino is not in the position to change the result once Client Seed is set. But under current PF implementation, FortuneJack has arbitrary power to decide whatever results it wants.


Below are the codes for two scripts that I have written with which I (as a casino) can take advantage of current system:

If I think Player will bet 'over 75' based on my assessment of player's betting history

Once he set-up Client Seed = 'mytopsecretclientseed', I will just use the following script to generate result lower than 75:

Code:

-snipping code-

If I think Player will place 100 auto-bets of 'under 50' based on my assessment of player's betting history

Once he set-up Client Seed = 'mytopsecretclientseed', I will just use the following script to generate results 'over 50' for 55+ out of 100 bets:

Code:

-snipping code-

This clearly shows FortuneJack is not provably fair because player's input of client seed is adding no value to the dice result.

Sequence 3: Update I received today from FortuneJack:

Here’s the update after the tech department of the Orbital Gaming (official provider of the new Dice game) reviewed the concern and the data you provided:

In case user deciding to set the role count to 100, still there’s a high chance of it resulting fifty times as ‘over 50’. We do agree with the fact that it’s indeed easy for the system to calculate fifty-five plus to hundred. However, 65-70 and starting from the counts of hundred, the estimating time will far exceed the time frame you’re talking about, approximately it will take us 5-30 seconds to make the proper calculations.


Even considering the fact that the majority of the players emphasize onto the so-called pyramid strategy and set the roll count to at least 100+. Generally speaking hundred rolls is not enough to make the conclusion about us profiting in the long term, as there are millions of bets made on Dice, making it impossible for our end to make the calculations that you’ve been talking about.


P.S - The majority of the leading casinos of the current market implement the Dice game and its Provably Fairness system the same way our platform does.

Feel free to let me know if there's anything that I can help you with, so I can make the final announcement for the community into the main thread.

P.P.S - we've decided to make changes in the upcoming update of the new Dice game according to the report you provided, (not changing the server seed after doing it so for the client one), so everyone, including you, can feel while playing at FortuneJack - even considering the fact that it doesn't influence the Provably Fairness of the game.

Sequence 4: Now I am posting my reply to the update I received from FortuneJack:

Point No. 1: When I said that casino can provide server seed which will generate result in favor of the casino in 55+ times out of 100 rolls, I was just giving an example. It was not conclusive. Casino can assess the player's behavior pattern in whichever way it likes and show the server seed accordingly. I can write you a script if you want with which I can study the player's betting pattern over the bets, say 10K-50K bets he made and on the basis of the study, if I start showing rigged server seeds for the successive bets, I can easily draw outcomes in casino's favor in 80%+ cases(considering ~20% anomaly).

Point No. 2: There is a difference between `result` and `outcome`. Result refers to the result of the roll, example, 8.14 or 58.50. While Outcome refers to whether player won or lose the bet with the result. In current PF implementation on FJ, I agree that FJ cannot decide the `outcome` because bet is placed after seeds are generated. But FJ can surely manipulate the `result`. If FJ wants the result to be 8.14, it can make that possible by changing server seed after player changed client seed such that hash of the combination of both results in 8.14. This manipulation can be used with player's behavior pattern (as discussed in Point No. 1) and outcome can be made in favor of casino in 80%+ cases in long-run!!

Point No. 3: FJ said that the majority of the leading casinos are using the same Provably Fair System as FJ does for Dice game. I would say, just give me ONE example of LEADING CASINO which has exactly same implementation as of FortuneJack! Comparing to FJ, some big names in my opinion are: Stake, PrimeDice, Roobet, FreeBitcoin, etc. All of these casinos show the SHA-256 hash of next server seed before user has changed the client seed. So these casinos have no control on both `result` as well as `outcome`. Among all big names, FJ has the weakest Provably Fair Implementation and you guys have to accept that.

Point No. 4: It is good to know that you guys have agreed to update PF mechanism in next Dice Update. But it is wrong on your end to say that current PF implementation doesn't effect the Fairness! It surely does! It makes the Client Seed irrelevant. No matter what client seed user sets, result can still be whatever FJ decides. The biggest plus of Provably Fair Implementation is that user can make the input and casino have zero control on the final roll result. In this way, it is impossible for casino to turn outcome in its favor in long term even after studying player's betting pattern.

Point No. 5: About 2 months ago, Hhampuz had launched a bug bounty here: Bug Bounty on FortuneJack | Get Rewarded for Finding Bugs. As per the bounty, a user would be rewarded 1 BTC if he finds bug in the Fairness. I know that this bounty is over but I still believe that my concern is genuine and I deserve the payment if FJ decides to change the Provably Fair system.

[FortuneJack]

Announcement regarding the concern of @webtricks about the Provably Fairness of the Dice Game:

The particular case that the user is talking about is surely no ordinary, and we as the company felt obliged to publicly respond to the user’s interest. It’s been years since we’re in the crypto gambling business, and the listening to the loyal community of FortuneJack as well as dedication to replying to every possible question of the players have helped us keep our presence in this everchanging market. That’s the reason why we’ve decided to update the entire Bitcoin talk community with the latest information:

We will not be considering the player’s opinion as a bug or a Fairness issue. Nevertheless, we’re willing to reward the user with some sort of deposit balance (as a gift from our end), so he/she can continue exploring existing and upcoming features of the games here at FortuneJack.

The vast majority of the casinos, building, running and implementing the Provably Fair games, use the same methodology that our platform does. The new dice game was publicly released only after successfully meeting the requirements of the industry standards, leading to us having the official certification of doing it so (Certificate issued by ITech Labs - Random Number Generator (RNG) by Orbital LLC and found that the RNG complies with the relevant standards).

We’ve been in touch with the development team of Orbital Gaming (official provider of the new Dice Game), according to the provided reports, there’s no way of us having a chance of possibly manipulating the upcoming results / outcomes. If anyone thinks, that still there’s some sort of way us having the control of influencing them in some sort of way, feel free to prepare reports, particular/exact evidence for the discussion. However, we would like to thank for your feedback and added interest in our casino games, including the Provably Fair ones. The thoughts and intentions of the community is our top priority, as a result, we’ve requested them to consider the following concern of the user, regarding the client/server seed changes, and we will be updating it in the upcoming weeks, so everyone can feel safe while playing at the properties of FortuneJack.

FJ, as a platform will keep adapting the new features, methodologies and will continue solving on-going challenges as general to keep the community engaged and entertained.

Okay! Since you mentioned Random Number Generator (RNG) and Certification by ITech Labs, I should explain how RNG and Provably Fair system are two different concepts and contribute differently to the Fairness.

What is Random Number Generator (RNG)?

RNG algorithm is used to make sure that the results are:

• unpredictable
• non-repeatable
• uniformly distributed

Casino decides a starting seed which in unknown to the public. Then uses popular hashing algorithm like SHA-1, SHA-2 to generate hashes for the successive rounds of betting. It is more of a precautionary step for Casino (host) than for Player. If results are based on RNG, casino can make sure that players don't anticipate the pattern of result generation by studying large number of bets because every bet is unpredictable, non-repeatable and uniformly distributed than the previous one. However, RNG Certificate doesn't prove that Casino is following the RNG Algorithm too because it is no way possible for player to verify the process of seed generation since it is done in back-end.

In order to involve player in the result generation process and ensure that player can verify the results, Provably Fair Algorithm is followed.

Now I am citing the text from the whitepaper of Crypto Gambling Foundation:

• hostSeed: Shall be kept in secret until the end of a particular game. Similar to a private key in asymmetrical cryptography.
• publicSeed: Players should only generate or contribute to it (with equal amounts of influence) after a commitment (e.g. cryptographic hash) of hostSeed has been broadcast to every participant of a particular game.

Remark 2.1.1. Broadcasting a commitment of hostSeed amongst players not only protects hostSeed from being revealed early, but serves as a verification of integrity, proving that during a game, hostSeed could not have been tampered without notice.

Using a mix of the entire hostSeed and publicSeed (e.g. by concatenating them) as an initialization parameter for randomization, every participant may have an influence on the outcome of results, with a negligible chance of manipulation in favor of any entity.

Source: https://cryptogambling.org/whitepapers/provably-fair-algorithms.pdf

Ok! Now I want you guys to read the above text at least 2 times and then decide if current implementation of FortuneJack is Provably Fair or not.

What is Crypto Gambling Foundation?

The Crypto Gambling Foundation prides itself in the verification and promotion of genuine true fair gambling operators. Through our processes and strict ideologies, players can know that the operators are running a completely transparent gambling experiences, and operators can not only evaluate their operators and coding, but also benchmark their practices with those industry leaders who are paving the way for the future of online gambling.
To be a verified operator by us, means that we have evaluated the provably fair algorithm built into these providers platform to be true and fair. As a player, it’s always best practice practice to also test and verify the fairness of your bets regularly to ensure further integrity checks.

There are several reputable casinos which have verified their Provably Fair Script from Crypto Gambling Foundation namely, bustabit, primedice, Stake, cyberdice, rocket.run, bustadice, Crypto.Games, DuckDice, OneHash, BitVest and BC.Game.

You were talking about industry standards, this is Provably Fair Standard and if FortuneJack passes this standard with current implementation, I will keep quiet and won't accept any gift/reward. But I am 100% sure that FortuneJack will fail this standard because hostSeed changes after the change of publicSeed.


I am not doubting FortuneJack and not accusing you guys of cheating the players. I am fully convinced that you guys are surely following RNG mechanism while computing Server Seeds for the players. But if you guys are claiming that you are Provably Fair too then make sure that you are following the most appropriate standard of Provably Fair. This should be your flow of determining bet result as per Provably Fair System:

Step 1: Generate a server seed using Random Number Generator (RNG) algorithm.
Step 2: Generate  SHA-256 hash of the server seed (i.e. generated in step 1).
Step 3: Generate next server seed following RNG algorithm.
Step 4: Generate  SHA-256 hash of the next server seed (i.e. generated in step 3).
Step 5: Generate a client seed using front-end javascript of user's browser.
Step 6: Show SHA-256 of the server seed (generated in Step 2), SHA-256 of the next server seed (generated in Step 4) and client seed (generated in Step 5) to the user.

Now if user decides to change the client seed, he will have the SHA-256 of next server seed and can rely that casino is not cheating because casino is already committed to the server seed generated in Step 3 for next bet.
