This caught even my curiosity. These winnings seem unrealistic on a 1% house edge and the number of games played. There must be some major pattern for the number draws within the algo. It is very hard to get the algo truly random. Stunna can you share the methodology being used?

[YaCoinYeah]

Must. Stop. Gambling

Let me know the verdict, is that statistically possible on 4k bets if they are truly random?

We are looking into that, will post more details later. Currently it seems it is possible it is leaning towards higher rolls ( against the house). As long as it isn't leaning towards us though we are satisfied for the time being. When we did simulations our house edge appeared to be .99% roughly. Will be doing more later.

At this moment things are going so quick, expect many positive updates/features this week. We are going to make bets on homepage/secondary pages update more seamlessly. Also working on adding tickers/better stat and session tracking tools.

Will keep you all updated with info regarding the concerns mentioned above.

Also feel free to follow us on twitter: https://twitter.com/PrimeDice    will be updating that more quickly

Lucky Nicely done. C'mon where's doog I wanna play lel

Your message was at 05:11:35 AM my time.  Guess where I was... 

I'm reading this thread (still part way through) and then will look at the provable fairness.  From the little I read it seems unusual because they seem to be saying that the player gets to pick both the server and client seeds.  But I didn't read much of it yet.

I played a few times.  Turned my 0.0001 into 0.00055669 which seemed like a decent amount.  Withdrew it, and only got 5669 satoshis.  I hadn't read about the transaction fee coming out of my winnings.

I assume client seed can be changed by changing something in your browser, server seed you just change by resetting. Waiting on your verdict though.

And woah, I go to sleep, come back, and you guys have had nearly 8000 BTC wagered with nearly 80k bets. Amazing stuff. Most successful first day launch ever?

From http://primedice.com/verification.php :

PrimeDice offers state of the art verification in order to ensure our integrity is never scrutinized

Is scrutinized the word you meant here?  I think you want it to be scrutinized, but never doubted.  Or something like that.

The user is freely able to change the server seed and client seed at their own will

I don't see how I can set either of these.  I see that betting zero or refreshing the page gives me a new random server seed, but is it possible to specify my own client seed somehow?  I need to be able to change the client seed, otherwise you could be picking seeds which give more low rolls than high rolls.

is kept scret until a day after the roll

Typo.

therefor it cannot be changed

Spelling.

first 8 digits [...] divide by 42949672.95 [Which is ((2^16)-1)/100]

32, not 16.  2^16 is only 65536.  8 digits times 4 bits per digit = 32, too.

From the FAQ page:

We have no way of knowing what the roll will be at any given moment, as the roll is all dependent on your client seed & the daily secret which we have no way of manipulating what so ever!

It seems you know all the secrets, and pick both the client and server seeds.  That means you know what each roll will be before it happens.  Maybe I'm missing something though.

Finally, there's a bug that happens occasionally where the balance is updated for a loss when you've won.  I think it's just a display bug, and that the real balance is OK.

Here's an example:  I just made a new account, got a free 0.0001 BTC, bet it all on the default x2 bet, and won.  Then bet the same amount again and won again.  My balance went from 0.0001 to 0.0002 after the 1st bet, then back to 0.0001 after the 2nd bet, when it should have gone to 0.0003.  Here's a screenshot:



Edit: and here's another screenshot taken 4 minutes later after making this post.  I didn't do anything to make it update, it just fixed itself.  I didn't reload the page or anything.

I assume client seed can be changed by changing something in your browser, server seed you just change by resetting.

There's an input element on the page where you can set the client seed.  It's 'type="hidden"' by default, but you can use the 'inspect element' feature in chrome to change it to 'type="text"' and then it appears and lets you change the client seed.

The scheme they're using seems fine, but they need to make it easier to allow you to specify the client seed.

Also, it's annoying that you have to wait 24 hours before the secret is released.  It's possible to avoid that by publishing the hash of the server seed before each roll, then publishing the server seed after each roll.  Then we can validate each roll instantly rather than having to wait until tomorrow.  In effect then every roll has its own secret, and the secret is revealed as soon as the roll is over.

@zaih this site is definitely going to become big. And the whole story of one of the first players winning 200+ btc and being offered to be paid immediately will definitely keep the success going even after week 1. Hopefully the house edge is truly 1% otherwise could get ugly. However, the whole gambling and doubling your money literally within 5 seconds will keep many gamblers going beyond their set targets thus increasing profits for the house in the big picture. Althought the big hit in the beginning, I wouldn't be surprised if Stunna has gotten back already 1/8 or more of that 212 btc lost in the beginning.

@Stunna I PMed you a question I have about your site.

[Moebius327]

Bots rolling over 99.3 and instantly cashing out. Time to take measures?

Hey Dooglus,

I have been eagerly awaiting your verification. Regarding the spelling, grammar and content mistakes, they'll be fixed real soon. Quite embarassing on our behalf, thanks for pointing this out!


Regarding the issue with your balance, I believe that's an issue we have when a lot of bets go through at once. Rest assured though, your balance is never modified server side, simply client side. Balance updates every 10 seconds, so shouldn't take long to correct itself. It's also a fairly rare occurance. We'll work to fix this.


As far as verification, thanks for the tick of approval as far as the "scheme being fine", good to hear. With the client seed though, we'll try make it a little more obvious as to how you change it. The idea with the hashed server seeds sounds really good. We'll be sure to implement that very soon.


Thanks!

I really need to stop.. 3rd time doubling my money. Sorry Stunna, even though you've said so many times you don't care

The rolls were going pretty slow (I assume due to lag issues), but tbh it added so much more suspense. I think you should leave the rolls slow I can see how it'd annoy someone who was down a lot and was 'impulse' gambling to get even.

Starting:



Ending:



Successful cashout! Didn't get carried away and cleaned



Edit: Yay back on the leaderboard too now

Perhaps try updating your java, we use quite a bit of Jquery. Let me know if this works for you.

Java != Javascript

Completely unrelated. You should not be running with Java plugin activated on your system.

Fair enough TF, thank you for correcting me.

It must be design related. Our designer doesn't work on weekends, so we can't do much about it at this moment, we will have him look into this when he's on.

@QuartX, Please provide me your Bitcoin address, sending you 0.1 BTC is the least I can do for your troubles.
