Is PrimeDice really (provably)fair?

[MGK-]

IS PrimeDice down?

[Gaukler]

new update

Profit= 415 x 0.00001 = 0.00415

The max unbalance between wind and lose was = 65 (lose) / 35 (win)

did anyone see a bigger unbalance



(anyway, for my system no problem)

[Stunna]

PrimeDice is provably fair currently and all bets can be verified. This process however is not as convenient as it could be, the developer of pd2 didn't quite understand what I meant when I asked him to add in nonces and thus the system somewhat relies on users setting a client seed. The majority of the posts here are plain fud and made by people with little understanding of cryptography so I never paid much attention to them, but some users brought some strong points to my attention.

Now that we're once again working on big updates for the site, we will be issuing a new provably fair system in PD3 which will be coming out in the next few weeks. This system will most likely be based off JD's, I'll also be running an open beta of the new site so anyone will have the opportunity to scrutinize this system and any other security aspects of the site prior to launch.  

Also, I'd like to offer a bounty to anyone that helps us develop a more convenient/user friendly provably fair system. I believe provably fair is heavily flawed at the moment as most users have great difficulty calculating their rolls and rely on third party tools to do so, or in most cases don't calculate them at all. I'd like to be more transparent with the community, and hopefully these changes and the pd3 open beta will be a step towards that.

Regards,

Stunna

update...

The system is against the player.. 100%..

i had a unbalance between win/lose about 15% Win / 85% lose  over 30 minutes...

you can calculate it -> http://de.wikipedia.org/wiki/Standardabweichung


So for me its done... never ever agin..

Winnings won't be normally distributed, but binomially distributed. How many bets did you make, and at what percentage to win each bet was made?

if you calculate it with my bet (850 bet), then you can be sure, that is not fair system..

let me explain a little bit more ..

example of win / lose

my math was wrong, i will post tomorrow

let me explain a little bit more ..

example of win / lose

+---+--+-----++---+----+----++----- 25 lose /  9 win  =  73.5% lose to 16.5% win

so after 850xbet, i got a 85% lose / 15% win  or in other words 722 lose to 118 win   

so do you think that is normal ?? In my point of view, that is not normal... so game is against player.

What was your win chance %?

I've had 19 losses in a row on autobets and not complained. I just now started reading this thread and oh my god are my eyes bleeding from all the whines and accusations.

Even if you are playing on 50% win chance, it's a 50% chance to lose on every roll, doesn't mean you HAVE to win the next one just cause you lost 5 in a row. It's still a 50% chance to lose.
Some people need to start using their heads. In dice games you either go big from the start and quit once you win, or lose it all and leave. With time the system (the 1% house cut) will bust you eventually.

sorry about my english....

Lets talk about the dices again.

First:
- I don't say, that the developer of dices had programed something against the player.
- And i don't want my btc back.. it was a small amount just to test. (0,025BTC)

Since 10 years, i play roulette in online casinos.
There is also a similar bet you can do on red/black and house edge (the Zero) like dices

What i also can tell you, there are good and bad "random generators".

So i did some test regarding the "standard deviation" on dices. And the result is,
that this random generator is a bad random generator. But that is just my opinion !!!

Bad random generator = the standard deviation is greater thus normal.

Conclusion:
So you can play dices and you can win, if the dices running on your side. And then you
can win more than normal. (More than a good random generator will generate) But if the dices are not
on your side, then you can also loose more than normal.

I hope, that will explain my last post's

I understand what you mean, I just can't tell if you're right. This is not a subject about which an opinion means much. If you post a history of the "chance to win" for your bets (eg 30% to 50% or 75%) and how many bets you made, I can tell you how likely your results were.

[Dabs]

And if any of the "dices" random generators are bad, then you can just flip it and make it good for the player. Just bet the other way and you will have the "dices" on your side.

So instead of losing more than normal, you should be winning more than normal.

I did around 4000 bet i think... for me enough

[AirFlame]

Ok this game is so scam i had 12 and then 14 looses same day in a row ! If You flip the coin you will have more chance to win than playing this shitty game. If i have no luck then I should die a long time ago on sidewalk crushed by the plane falling from the sky... or driving a car on highway and smashed by the train that have derailed and moved to the highway.

Show picture with 20 loses in a row at 90%, then speak

Please... flip the coin in the air 12-14 times and check if You get 12-14 times tails

[AirFlame]

flip the coin 20000 times and come back.
12,14,22,25 is normal with 49.5%

Spin your doge 20000 times and come back..

Yes, you will, because this game has a house edge.
That shouldn't be a surprise.

According to your screenshots, you've made over 378 million bets.
With that many bets, losing 14 in a row at some point isn't surprising.

No, that's the total number of bets at the site. Your point stands though.
