Bitcoin Forum

When you stroll into a casino, approach the cash desk and leave with a handful of chips you do so for one reason and one reason only. You have faith that you might leave the casino a winner. This faith comes from the belief you have that the outcome of the bets you are about to place will be random.

You walk to the roulette wheel and place your bets on the table in the sure knowledge that neither yourself nor the person spinning the roulette wheel has any influence over the outcome of the spin.

This is not always the case online. You find a site, complete your due diligence and you make a deposit. You play and you lose, you play some more and lose some more, and eventually a thought crosses your mind… what if the site you are playing on is not fair?

How do you know that the casino you are playing at online is not simply generating any outcome that guarantees them the win?

Step to the rescue, Provably Fair. The latest online casinos are embracing a ground-breaking technology to completely remove this doubt from their players’ minds. To generate a random outcome, gaming sites utilise a seed and run this through an algorithm. A seed is simply a starting point to generate a random number and an algorithm is a series of steps taken to convert that seed into a pseudo-random result.

In a Provably Fair gaming environment the site publishes to the player the seed they are using in advance of the game, however they do so using encryption, such that the player is only able to determine the seed after the game has taken place. In a Provably Fair game, the player also provides their own seed to the server which is used as part of the random number generation process.

Once the game has taken place the player can decipher the seed belonging to the casino and verify that the outcome of the game they have just played was completely fair. That is, the casino generated the most random result possible without unfairly influencing the outcome in their favor.

Quite simply put, Provably Fair gaming is the fairest way of gambling anywhere online in the world.

Which is why when you play at a Provably Fair gaming site, you know the money you wager is in safe hands.

Really amazing article. Provably fair is something that I remember in this community was a MUST for all websites... Now it's fading away. Be safe & play where you know you can verify your bets.

I wish Dooglus was still around these places keeping an eye on things haha

Very well written article. If you're a Bitcoin gambler, YOU NEED TO READ THIS. It's something that people are neglecting and a simple form of technology that can be easily implemented. Why are casinos not doing this? It's so easy, so they could easily have non ethical reasoning behind the scenes...

https://cryptogambling.org/why-should-care-about-provably-fair/ (I recommend reading the article on the site, better formatting)

Why YOU should really care about Provably Fair...

In many instances people have posted "Provably Fair" on their site and they have no " Provably Fair" system in place. Your average gambler will never investigate further and they will just accept that the site is " Provably Fair ". I hope the more technical inclined gamblers will fill that loophole and test and educate the people who has no clue how this system is supposed to function.

I also hear people can implement systems that looks " Provably Fair ", but once it is tested it turns out that it is rigged. Is this true?

I dont know if someone would decide to put their time or efforts on educating most of the gamblers on how they should verify if a site is provably fair knowing that not all gamblers are tech savvy which they would really have a hard time on realizing on what are the things being mentioned on here about provably fair this is why they dont really care at all as long they would able to see that there are lots of people do play on the site which they can assume that the site is provably fair.

After trying many gambling sites, for me, i don't really deposit big amounts on gambling sites because i do not expect to earn on those. I just deposit to see how and what are the games their. The only gambling that i actually had withdrawal was yobit.net  but that was a long time ago. I do have some withdrawal from gambling sites but the amount is not as high as how much i had in yobit.

You might be get hacked also dude. What have done is perfect to save your bitcoin as well as to utilize the bitcoin in gambling. Still now bitcoin dice roll is working in Yobit site. When the bitcoin value was around 400$ I use to roll for 0.002 BTC for every roll but now value turns to 4k and even more. Yobit mostly operates as a trading platform only.

im not really into dice sites. but good info over there. thanks for sharing.

If you're in live match for example Vegas, I think there is not provably fair anymore , it's pure based on luck !

Most players I have spoken start to play at a site based on the recommendation of a friend and they don't check basic things or care if a provably fair system is implemented.

If a casino avoid to implement this easy provably fair system, then they probably have something to hide?

Make a poll how many players care about it and you will be surely surprised.  :)

Tbh i'm not verifying my bets, for a site have this and running for how many years like pd I don't bother to verify my bets if I lose. Having these feature makes you more comfortable that you won't get scam especially if you are a high roller.

Accurate observation. The same goes for "licensed" and "regulated" and to some extent even lowest house edge or best odds. In fact, if you stroll through the casinos advertised even on this forum, you'll find some glaring misrepresentations.

I definitely agree that Provably Fair is now the minimum standard. But players do have a rather steep learning curve when it comes to verifying for themselves if the Provably Fair mechanism is as it claims. For the larger sites, there are open-source tools out there to use but that still requires manual verification of each wager made. I admit myself I hardly ever verify my bets at places I already trust, beyond the first few I always do when signing up to anew place.


I've seen at least one alleged case, which you can discover for yourself in this forum, where the system apparently would only show the seed if you expressly requested it. It's since been fixed.

This is one area, where we need a White Hat hacker initiative, where knowledgeable people could test these sites to see if their systems are "Provably Fair" or if the house edge is what is promoted on the site. These people should in no way be affiliated with these sites and not be bribed or influenced by these people.

Most people just use these sites and blow away their money on untested claims. Misrepresentations has become the standard now and nobody are challenging these claims. If this continues and consumers are exploited enough, law enforcement will get involved and this scene will get heavily regulated. < Most of them are running their online casinos from countries or independent Islands, where these law enforcement agencies cannot touch them. >

I believe there are a number of "decentralized" efforts (sorry, I had to do it!) doing precisely that, even on this forum. I think the gambling community just needs to look out for each other, and to learn a bit of discipline by doing their own research.

As you recognise with bribery and affiliation, at the end of the day, it's difficult to rely on information when there are other agendas. You've got services like Game Protect here who also have their own website and claim to protect players from these "bad casinos" but they hurt their own credibility by also promoting affiliate links.

But I've seen more effective cases here on this forum where casinos are brought up against their claims. Community pressure prevailed in some. Reputation is more powerful than law enforcement here.

Thanks for the useful information.
I would like to add up something.
The fact that the casino site allows you to view the source code doesn't mean that they are using it as the code for their casino game.

You should always view page source and make sure that it fits the code that they show you, sometimes they show one code and use another.
Don't fall for non-random generators.

Well, the problem does not really lays with the checking of the code and comparing them with what they actually use. The problem is that 99% of the people that play on gambling sites do not care or do not know how to do it. The thing is it is extremely difficult anyway to determine if the site is using some cheat to win, after all if they were cheating they would hide it pretty good.

Provably fair is important as it makes sure you are not being cheated by the site's admin by making the results appear a sthey want to. They can make easy profit by doing so and players get looted.

Sad to see a lot of websites like Bitstarz still being used despite being brought to light they aren't fair & also abuse terms etc.

Spread this word guys, sites which put the effort in should only be used, they will not CHEAT you of your money.

No need to spread words. They are already well known for being that. Why does there are user that still choosing to play on untrusted/unknown reputation gambling site while there are a lot of trusted gambling site existing which is already listed on this forum. I will name some of them, FortuneJack, Primedice , Bitsler, Nitrogensports, OneHash and many more. Just search for the forum for the list of active gambling site so that you will be always be guided.

I didnt even try to play at yobit but basing on the players feedbacks that i did able to read back in the past their dice site isnt really fair at all.I dont know if its true or not but presuming on their reputation when it comes on exchange matter they do really have a bad reputation and i didnt even tried out to use the site either on exchange or gambling.

I don't know if Yobit is fair. Do they have anyway to prove that they are fair? I don't think so. Still many many people play there and it is always busy. The house edge there is very high most people will say and agree. I think so too because you can feel it. I don't like how Yobit defaults the dice to 0.01 and they put that right by the chat so they hoping you play by mistake. Rather play dice on a proper dice site with probably fair and actual support since Yobit don't provide much support staff all. Also the house edge is much lower. Only 1%

You are right! Provably fair, it's an important thing which it should added in a gambling site, to show people that this site is fair enough to play on it. I knew few gambling sites that allow people to see the algorithm with proof to trust the site.

Probably fair gives an added trust or makes the particular gambling website more legitimate in comparison to other gambling websites. Another thing is based on the house edge allocated as well the platform on which the event has been developed too makes it provably fair.

Problem is not all sites that say they are provably fair are really provably fair. There are some that just throw around the words and not really back up what they are saying. It's common to see especially with new casinos and fly by night ones. There should really be a body that would handle these claims and check for their authenticity, Some even have their own system and saying it is provably fair but in fact it is not up to standards.

I think there is some group that review if the site is actually implementing provably fair  games, and wheneve a site is found lying about it, they were bashed and have negative feed back on its rating, telling or warning gambles to stay away from those cheating site.  Provably is really needed so that we ca be sure that the site is not rigging the game.
