Yes, it is fair. You can read Bitcoin Reviewer's post on provably fair bitcoin to see how the system actually works.

Just because you were unlucky does not mean that the game is unfair.

on a 2x game... i had 13 rolls against me the other day (friday the 13th, no joke) on primedice that occurred just before 1000 rolls was up, lost the entire bankroll... this is after the previous 1000 rolls had a 10 rolls against me

i should probably not play the lotto huh...

wtf are the chances of tails coming up 13 times in a row...

This is an interesting concept, but it doesn't relate just to PD, more like to anyone. I have noticed very strange losing streaks on some of the sites, like once I had 23 losses in a row with a chance of 1 in a gazillion.

However, do you have proof?


 re: very strange losing streaks

imo 1 of 2 things are happening====?


A. THEY ARE CHEATING


B. THEY ARE BEING HACKED AND SOMEONE IS EXTERNALLY CAUSING A "PENDULUM EFFECT"

Higher than you think. Quite often on all the dice sites.

i calculated that it was something like 1 in 8000ish if I did my math right, so after rolling 2200+ times, it was not a shocker, but did suck

Fair? Well, it's hard to decide...
I got a run where had 3 win, and 7 loss, on 75%. It has to be opposite. I had a real interesting run too, where I got 10 win, and 20 loss, on 66%, that was not too fair, I think Roll Eyes

So also 98.4% for winning 7 times in a row, right?
Yes.*

Quote
Which never happened.
1. Run 1000 rolls.
2. Make sure that You wasn't busted and really made 10000 rolls (bet 0 for example).
3. Check streks again.
4. If You don't have 7 wins in row somewhere, go play lottery. You are lucky. Well, kind of.


*edit - in fact no, as it was calculations with house edge included, but whatever - close to 98.4%.

Only known (not including funny shit based on "Script Knows What To Do Now" concepts, that works only when You can't change client seed) "anti martingale" system is limited bet. There's limit on PD - You can't win more than 10 BTC in single roll. So if according to Martini You have to bet 8 BTC on 49.5%, You're busted.

The best anti-martingale system is YOU and Your blind faith in Martingale. With bankroll 0.005 and inital bet 0.00002 You will be busted after 7 loses in row. Chances for 7 loses in row is 0.8376057438%, BUT when You roll 1000 times, it's damn 98.4%. Deal with it.

Poor impulse control.

It's possible to assess the possibility that any dice site is scamming you. Send me some data (min 1000 rolls for any given bet) and I'll have a go.

Primedice still has not changed to nonce betting. Been quite a bit of time already since the change was claimed "coming". Doing similar to what bit777 did, claims change was coming for provably fair but instead just increased marketing and left his games NOT provably fair at all.

To be fair it's completely provably fair, people just have to change their client seed.

It's a bit like Peerbet's instant & non instant games. If people trust PrimeDice, don't bother changing the client seed, if they do, change it.

Primedice IS provably fair, just not as easily provably fair as it could be.

That article, also says this "At no time, does this post accuse any casino of cheating."

And the final paragraph:
Quote
The analysis presented here examined a specific implementation of a browser-based "Provably Fair" system. Other implementations of this concept will vary from site to site, and may or may not exhibit similar vulnerabilities. Non-browser based implementations of Provably Fair (such as SatoshiDice) do not exhibit these weaknesses and are not the focus of this analysis.

Of which I can say, that if you as the player, check the numbers and seeds before you click on "Roll" or "Bet" or "Deal", you will have the same provably fair system as the non-browser based implementations.

Quote
That said, now that the analysis has been released, I would agree that if your casino carried out any attacks, the damage to your reputation would be extreme.

Then the author continues to comment further:

Quote
On most browsers, you are able to examine network data passing between the client and server, so it is possible to see the partials, but detecting them might be another matter (more on that when I grab a free tutorial).

Yes, I agree, it is definitely possible to implement a provably fair game in a browser.

Quote
As long as one scrupulous person can run a few tests and definitively prove that the site is cheating, then the entire casino becomes invalid and all customers will leave.

If you can set the client seed, AFTER you have recorded and seen the server seeds, and verify that it was not suggested or changed at any point while you are playing, what can get more fair than that?

It is not fair to accuse any site of being unfair when you have no proof at all, especially when they provide you all the tools you need to verify the fairness of the game. Gut feel and beliefs, (this is not religion) are irrelevant when you are faced with math. 2 + 2 = 4. That can never change.

I'm sure nearly all the dice sites have an "Anti martingale" system, as for me my experience in Primedice has confirmed so.

For example, I started with 0.005BTC betting 0.00002BTC each time at 50/50 and doubling if I lost. Some times my nimber had to be over 50.5 or below 49.5.

But its interesting that my longest win streak was of 3 after doing +1000Bets and the longest loose streak was 10+(lost all).

These things let you know something is not fair in this game, after that no more "dice" for me. As I don't think is truly 50% win.

Just my 2cents

I will refer to the excellent article written by TrevorXavier: http://www.reddit.com/r/Bitcoin/comments/1frm4x/provably_fair_by_bitzino_not_provable_with/

And provide a quote from it I also believe to be true.

Quote 1 “Bet Discrimination Under the assumption that an investigator will not place high stakes to investigate cheating, the house can safely offer a fair game to those using play money or very low stakes. As the bet size increases, so does the probability of an exploit. A house can also analyze betting patterns (progressives) for ways to minimize its short term risk of ruin.”

PrimeDice i believe is fair for micro bets.

PrimeDice i believe is unfair and cheating on bets 0.5 btc and above.

All should read the post linked. It simply is a must for anyone involved in btc gambling.

I just hope the switch to the nonce verision will be quick as all accusations can then be fully dropped

I visited the site about 24h ago and then it did have nonces.
Unfortunately this fixes nothing as the site still knows the next client seed (if not changed by the user himself): the old one with the last number replaced.

Uh. You started this all. So yes, you first remove your first unfairly posted negative rating. It is not towards me. That is my condition. You first remove your negative ratings from all 4 other people you gave negative ratings to. Then I will remove mine.

Your choice.

I am not going to remove it until they remove. I have not given them rating first.
