Did you read my conclusion ? 

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

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 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.

sorry about my english....

anyway
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

Mind sharing your username?

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.

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

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?

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..

 

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.

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)

IS PrimeDice down?

you need a satoschi management system...

don't play the martignale or whatever the name is. that will never work.

but there are other system and that works fine for me...

I start play every time with 0.00001000

And i have 0.005 as Balance

0.005 Balance
0.00001 Play

I already got 228 x 0.00001 and never loose my Balance


Is there a difference if i play with 0.5 Balance and 0.001 ?? any experience ?

update New status 305 x 0.00001

sure thing! You must just own your entire gambling site(php, server etc) on your computer, and then you play it until you are bored. But you will probably earn what you put on your wallet(because it will take your money from your wallet to pay your winning, so it's a loop)
You can't win more than what you have and you can't make your money grow.

By the way, back to the topic.
I mostly do a tricky trick. Well it's not a trick, but a prove of luck.
Let's say I have 100K satoshi and wanna find more than 99.50 as a roll.
What the server will do?
I set my own client, and let the bot run 500 satoshi per hit. and just for pure luck for who knows the 199 bet is a winning one. and so I win my 100K back. Or better. at number 72 and 199 I get over 99.50, and I have a profit of 200K.
I do the same, Change the client seed, add some pepper and decide to bet 2K for bet, and at the 3rd I win big.
I took examples from my own experience on the website.That's why I'm talking.
And my example doesn't even involve martingaling.

removed.....

Nope.

a stupid question, can gambling website be playable offline?

@uoyeparannog, how much is your dice site? I want to make one for an alt-coin. But we'll make it fair of course.

Any change to the client seed will do the trick. Either in part or in whole. They know what's your next client seed if you don't change it. They know the secret seed. They provide the third server seed and can calculate what their provided server seed will roll with your known client seed and their secret seed. Thus they can try multiple server seeds and give one which gives the roll they want. They can't do this if you changed the client seed before the roll as the client seed will then not be the one the expected and calculated with.

Depends on if you trust them or not. If client seed is not changed before every roll, the "provably fair" check on the seeds doesn't mean anything. I'd recommend changing it before every roll until they update their seed system as it is the only way for rolls to be actually provably fair as it is right now.
