Hmmm, just for statistical analysis I threw the dice 1000 times and this is the outcome (with >50.50 as winning operator):

Won 494 times, lost 506 times. Ok, seems fair with a win-rate of 49.5% but, the average rolled number is 49.31007. After 1000 spins I would've expected this to be closer to 50, but whatever. This analysis took 2 minutes which shows that the server is definitely faster now.

Hmm. Would you be able to do a simulation like that and print every roll? Then post on pastebin or something with every roll as a new line?

That'd be cool to see. Maybe there's patterns in the random. I heard Vink uses pre rolls a lot.

[vlees]

The outcome is based on the SHA256 from a long string. It is safe to assume that there is no pattern in there. But I can do so in a few mins/hours I guess.

" To verify your provably fair bet, simply take the sha1 hash of our secret with the client seed and server seed (In the order: Secret, server seed, client seed). Take the first 8 digits of the new sha1 hash and convert it from hex to decimal. You will then need to divide by 42949672.95 [Which is ((2^16)-1)/100] in order to get a 0-100 base 10 numeric value. This value will have been the roll. "

Does that make a difference?

[vlees]

take the sha1 hash

You are right, it's SHA1, even though it is to some extent predictable, doing so is still unfeasible to do so in this case.
To read more about why SHA1 is usually bad: http://www.schneier.com/blog/archives/2005/02/sha1_broken.html

Also currently sampling the data for you.

EDIT:
2827 bets, semi-colon separated. For all bets I picked >50.50 as winning parameter and the client seed was set to 0.

First column: WIN/LOSS
Second column: The roll-outcome
Third column: Server seed used for calculation

Thanks!

[joker_josue]

Of course it will be hard to be a pattern because all games that work this way, could be addicted.
I will analyze this file. Thank you.



With so many betting, does anyone could give me some coins for me to play?

Free coins are free.. right  

Hey all,


We've updated again, this time rolls should be fixed completely! On my connection they're taking a little under 0.5 seconds. It may be a little slower depending on your internet. This should make playing with PrimeDice a lot more enjoyable since we all know how annoying lag is.


Thanks for waiting, I deposited 0.01 to your account Zaih btw. Seems you were only one who posted their username/bet id/account id, reminder to all to set a unique username for themselves.. Thanks for waiting!

can i have a free coin as well? User: Shah

Small analysis of the data above:

After 1: 25.04% win vs 24.94% loss: 49.98% win chance
After 2: 25.33% win vs 24.66% loss: 49.98% win chance
After 3: 24.83% win vs 25.11% loss: 49.95% win chance
After 4: 25.89% win vs 24.05% loss: 49.95% win chance
After 5: 25.4% win vs 24.51% loss: 49.91% win chance
After 6: 25.36% win vs 24.58% loss: 49.95% win chance
After 7: 25.33% win vs 24.66% loss: 49.98% win chance
After 8: 24.73% win vs 25.29% loss: 50.02% win chance
After 9: 25.01% win vs 25.01% loss: 50.02% win chance
After 10: 24.73% win vs 25.26% loss: 49.98% win chance
After 11: 25.01% win vs 24.94% loss: 49.95% win chance
After 12: 25.29% win vs 24.62% loss: 49.91% win chance
After 13: 25.26% win vs 24.62% loss: 49.88% win chance
After 14: 25.29% win vs 24.62% loss: 49.91% win chance
After 15: 24.66% win vs 25.26% loss: 49.91% win chance
After 16: 24.66% win vs 25.29% loss: 49.95% win chance
After 17: 25.61% win vs 24.3% loss: 49.91% win chance
After 18: 25.47% win vs 24.41% loss: 49.88% win chance
After 19: 25.19% win vs 24.69% loss: 49.88% win chance
After 20: 25.01% win vs 24.9% loss: 49.91% win chance

How to read? So, you have won the last round, you want to know what the chance of winning after 5 spins is. So in the row: After 5, you see it's 25.4%. Was your last round a loss, then after 5 it will be 24.51%.

(this is done with winning with 50.00 and higher).

What does this show? Nothing, it's random.

I did an analysis very quickly, and can conclude:

When the SHA1 is 15 to 23 characters, the probability of a victory is greater over 50.50.

When have 16, 17, 20 and 27 characters, the probability of being a win is greater below 50.50.


This does not mean anything, but it gets the note.

[vlees]

Also some random data which does not say anything at all:
at a distance of 472 spins there is always a win in my data.

Why is this useless? There were other spins inbetween.

To complete the post above me:

hash-length: average number rolled
15: 54.120054054054
16: 51.2192

29: 47.8068

Another note:
When the SHA1 starts with "3" are 56% of wins above 50.50

Got a sample of 10000 bets. Everything goes more towards the 50% so it's safe to say you can't get any useful results out of this at all.

the variables are endless ... is difficult to find a pattern

[joker_josue]

Can you tell me what was the bitcoin address that was in the game when I made this transfer?
https://blockchain.info/pt/tx/a3a3a9d78f4a7fc7368d6fe978066f558bf861cd5b34ffa9ac28a1c9ae7c1bac

It's just that I do not remember what was the address I used ... and wanted to continue playing ... 


Stunna... anything I can do?

What was your balance when you left it overnight? Also, do you have your ID?

I did not deposit and then played ... so it should be 0.0001 btc

My problem is that I do not remember what my ID ... 

Feel free to put in a new address and make a new account. I'd be happy to credit you a corresponding amount.

Thank you.
I have created a new account.

BTC Address: 1HLWN3sdTc2gnzQrsk5tF1ysjwmGynFNSd

ID Game: 26e338fe6f1d3ffe020f711b45c4be69

Just to inform you that due to the situation that said I had, was reimbursed by the PrimeDice! Thank you!
I'll have fun in the game.

I won BTC and cashed out but it hasn't shown up in my Blockchain wallet yet?

You should receive it as soon as your deposit reaches the proper number of confirmations. If it does not please inbox me.

You will then need to divide by 42949672.95 [Which is ((2^16)-1)/100]

It still says that?  2^16 = 65536.  It should say 32 not 16.  I reported this error quite some time ago.

[dooglus]

I just played a few rolls to see how fast it plays now, and I have to say it's much better.  My Internet speed here is horrible, but I still get my rolls done about as quickly as I can do anything else online.
