maybe just a frustrated gambler who lost BTC
Nah, I think he made an honest mistake, he had been using an old verification script. Was it sorted out?

maybe just a frustrated gambler who lost BTC
I am not familiar with running NodeJS so I made a quick PHP script and I am getting:
fa7ae - 1025966 - 59.66
21fdd - 139229 - 92.29
a05cc - 656844 - 68.44
The first result is more than 1 million so it goes to the next one which results in 92.29 after the modulo function (and is correct AFAIK.)
There is 02 in the first result so perhaps your 0.02 result comes from there and there is a mistake in the verification script?
Also 11 consecutive-losing bets is nothing special at all. Verifying of bets is always good though.
fa7ae - 1025966 - 59.66
21fdd - 139229 - 92.29
a05cc - 656844 - 68.44
Code:
$hash = hash_hmac('sha512', 'ca45edd88ef251dd43edf42dc97c7ffb-3391','41fa224237f452360db8d35a276f4067fce6cad8d3dbf3c73bde2e804c8cb8c7');
for($i=0;$i<30;$i++) {
echo "
".substr($hash,$i*5,5)." - ". hexdec(substr($hash,$i*5,5)) ." - ".(hexdec(substr($hash,$i*5,5))%(10000)/100);
}The first result is more than 1 million so it goes to the next one which results in 92.29 after the modulo function (and is correct AFAIK.)

Coinfist is a (paid?) shill. His bet should verify now. Earlier today he attempted to verify using an out-dated script we had listed on our verification page which was quickly fixed. Not much more to discuss here, note that he posted this thread after this was fixed.

Primedice is cheating
Yesterday I was just using PD to bet and doing the double-or-nothing experiments.
It was going fine at first. But suddenly, I had 11 consecutive-losing bets.
They were pretty odd, weren't they?
So I did some verification using the script provided by Primedice.
See the screenshots below. I did verify all 11 bets. All 10 bets are correct, but the No.2 bet from top is wrong.
On the screenshot, the roll is 92.29. However, the result I got from script is 0.02.
So I should win that bet, there would not be the last one bet(top one) which cleared me out.
Please don't say that your verification script is not updated.
What's the purpose of the verification script that site does not use and can't verify result?
So whenever someone finds you are cheating, you can say it every time?
Return my money back, you scam site.

You can look up these bets by the bet id shown in the screenshot and verify them by yourself.
This did not just happen once but twice today and almost clear me out.
Since Primedice has been online for so long, I could not imagine how many times it has cheated.
I probably will do the same experiments on other bitcoin gambling web site. But Pirmedice is not trustworthy and return my bitcoin.
I also found the possible unfair when you PVP with "strangers" on Primedice.
See the post: https://bitcointalksearch.org/topic/m.8315850
I only used PD for several days, and already found 2 unfairness.
How you can still claim yourself 100% "provable fair"?
The script I am using:
//the seed pair itself
var clientSeed = "ca45edd88ef251dd43edf42dc97c7ffb"; //dont forget to exclude the dash and the nonce!

//bet made with seed pair (excluding current bet)
var nonce = 3391;
//crypto lib for hmac function
var crypto = require('crypto');
var roll = function(key, text) {
//create HMAC using server seed as key and client seed as message
var hash = crypto.createHmac('sha512', key).update(text).digest('hex');
var index = 0;
var lucky = parseInt(hash.substring(index * 5, index + 5), 16);
//keep grabbing characters from the hash while greater than
while (lucky >= Math.pow(10, 6)) {
index++;
lucky = parseInt(hash.substring(index * 5, index + 5), 16);
//if we reach the end of the hash, just default to highest number
if (index + 5 == 128 + 1) {
lucky = 99.99;
break;
}
}
lucky %= Math.pow(10, 4);
lucky /= Math.pow(10, 2);
return lucky;
}
console.log(roll(serverSeed, clientSeed+'-'+nonce));
