The casinos that truly have provably fair and the ones that can rig them

[khaled0111]

What the OP said and the explanations he gave do not necessarily mean that the casinos on the second list are manipulating game results (scamming their users). But, if true, it clearly mean that those in-house games are not provably fair as advertised.
Contacting customer support, especially via live chat, and asking for clarification regarding such issues is a waste of time as most agents do not have the necessary technical knowledge to address these concerns or provide accurate and satisfying answers.

This topic would be more complete if OP can add some proof to back up his claims.

This is exactly why community-driven reviews still matter so much. Static “best casino” lists don’t catch selective scamming, payout delays, or changes in behavior over time - but real players do.

We’ve been leaning more into transparency and verifiable fairness rather than glossy marketing, especially around how casinos actually operate under stress. For anyone who wants to understand what provably fair really means and how to check it themselves, this is a good starting point:

Trust is built from testing, not promises.

Accusing or making up some words in saying this and that in regarding about having that potential rigging up their games but cant be able to prove out some solid proof then its just that simply stating his idea but still people wont be that believing considering that those casinos mentioned on OP are known. Provably fair, yes we are that minding of these things because we do want that in every bet we can surely say that everything is fair and there's no rigging involved but it doesnt mean that those others who doesnt have means they are not fair. Come to think that everything would be still become a loser in the end of the line, house do always win at the end and thats why im not minding that much as long im sticking or playing on a known and credible casinos then this whats important.

The key distinction many people miss is that “provably fair” isn’t a marketing label — it’s a cryptographic verification model.

If the server seed hash isn’t provided before gameplay and later revealed for verification, then it’s not truly provably fair, regardless of branding. The ability for players to independently recompute outcomes using the server seed, client seed, and nonce is what makes manipulation detectable.

In our research on cryptocasinos.cc, we’ve found that most misunderstandings come from players not knowing exactly what should be visible before and after a bet.

Transparency around seed commitment is critical.

It would be interesting to see standardized verification guidelines adopted across platforms.

Agree that the topic will be more complete if the op will indeed provide proof to back up all that he has said.
Personally, I've always believed that not every casino that advertise their system to be provably fair actually operates a casino system that is indeed provably fair, this is one reason I hate to jump from one casino to another in the name of search for that perfect one, for in this process, one could easily jump from frying pan to fire..

And speaking about contacting customer care concerning issues like this, even if they know, do you think they will let you in on that knowing well it's the casinos source of making money from their users even though it's in illegal way, understand that the customer cares service personnels work for the casino and not for the customers, the personel can only share with customers what the casino's management allows to be shared.

You are right. Most of times those who work on customer support only have knowledge on what to do in the case of regular troubleshooting. They don't have idea on how a random number generator works or about the cryptographic functions which are used on provably fair games.

The ideal thing to do would be to stick to games which are provably fair by default and learn how to check seed by ourselves, instead of bothering customer services with questions they do not have answers for.

They’ll usually just say “refer to the TOS,” and that everything we need to know is written there. But for regular gamblers, most of the time they don’t really focus on technical stuff like whether the games are provably fair or not.

What they look at more is the popularity of the games and the casino itself, because once those are well-known, people just assume they’re safe and not being manipulated, even if they don’t really check the details anymore.

I admit to doing this because, for me, reputation is more important than this provably fair stuff. Besides, we can't assume that everyone who gambles does so solely for making money, which matters to them. Maybe those who are deeply in love with gambling will spend time digging it, but for most, it was nothing.

Whether the casino is provably fair or not, a gambler will choose a preferred casino. And we choose because we trust them, not because they are special from others. Besides, this won't change the odds of winning.

But if we are going to make these provably fair games a topic, are they still as popular as they were some few years back ?? I know for certain most of our crypto casino's have a catalog of games from third parties which makes this a tough topic to bring about unless it's a thing of bad experience with them 

And with these strong allegations, some proof would be nice.. maybe a YouTube link for starters..

[khaled0111]

Well, I don’t know why this thread has been brought back to life again, especially that OP’s most recent reply dates back a month.
Anyway, OP doesn’t seem interested in engaging in the discussion (about provably fair systems) that he started. So, I’m not sure it makes sense to continue posting here.
OP started a very good list, but he should keep it updated (he should make a post with every update). Otherwise, that list would be worthless.

[Z_MBFM]

I don't know how many sites you have actually tested and published. There are many casino sites on this forum that are probably fair. But you only mentioned a few sites here. The probably fair topic increases the players' trust in a site. Because it reveals fair results with a player and has a valid proof of it. Apart from the sites you mentioned, I have seen many other sites where probably fair is used. So you should list the rest of the sites here since you did not create this topic on behalf of any site impartially.

[Odogwu-Blockchain]

OP might be saying the truth but what may seems to be false information is lack of proof and evidence, from his explanation, I could feel the authentic information OP is passing but we can't actually believe it, it's a voice over the counter and not tangible proof for more evidence.

If the author of this topic should send screenshot of what he means, note screenshot should be self explanatory and not complicated, would've been good.

Upon making some research in the industry, unfortunately I find out most casinos falsely advertise their supposedly « probably fair » games, while these games are in reality the ones that can be rigged the most, because they’re in-house games and the owner of the server can decide any result he wants to give out to the player. Not that they are always rigging it, or that I’m accusing them of rigging it, it’s just that their games are not provably fair, so they can rig them.
I will be listing here the result of my research. I might update it following suggestions.
Edit: if you’re not interested in provably fair, and for some reason not able to understand it, it’s not a big deal, no need to spam this thread. « Reputable » casino does not mean you can prove their games are fair.

First list: It is impossible to cheat the player with proper knowledge (can prove if he’s been cheated for any given bet independently)
Second list: It is impossible to prove the fairness of the game, no matter the level of expertise of the player


Casinos with true probably fair games:
Duel.com
Stake.com
Shuffle.com
bc.game: with some caution. Impossible to put a client seed in a blackjack game, so that one is not provably fair. Though Hi Lo and fast crash are provably fair.
wolfbet.com


Casinos with false provably fair games:
Roobet.com: Does not give the server seed hash before game starts. Customer support seems to be a stupid answering robot machine when the subject is brought.
Metawin.com: The code used to verify the results is no where to be found. In addition, server seed hash seems to change after game starts. 3 tickets created on the subject, 3 closed. No moderator knows where that mysterious code is hidden nor why the server seed hash has changed for my bets.
Wild.io: the system forces the player to choose client seed before server seed is chosen. Customer support says no it’s the contrary but then stops responding when shown evidence or asked to try it themselves
Bitstarz.com: Same issue as wild.io
Rollbit.com: No server seed hash before game starts (last seen about a year ago). Their NFT game can be rigged with last minute house bot bets in the first milliseconds the 50th eth block hash is known. When asking why not stop bets 1 or 2 eth blocks before result is out, moderators have some stupid answers.

Hey OP great topic regardless of the naysayers who defend the casino's. I have proof that the original "provable fair" is a scam. I posted about this topic as a bug in their system a year ago but never heard back from the casino. I have the original script from crash and I bet it doesn't match the current. Even when the casino's in house games paid so much better they where still rigged in the casino's favor. If you control the nuance count you can manipulate the outcome and everybody who knows knows! Great topic and thanks for posting.

Whether the casino is provably fair or not, a gambler will choose a preferred casino. And we choose because we trust them, not because they are special from others. Besides, this won't change the odds of winning.

It’s mostly about provably fair games. A casino can offer different types of games, like sports betting, and I guess some people would still lump that under “fairness” since you can verify match results online. But when people talk about provably fair, they usually mean games where the fairness can be verified on-chain, not just checking the outcome on Google. That’s where the confusion starts.
