Fail to see how this is provably fair 

[avencard]

Zaih, the provably fair verification will be available soon.

You shouldn't have released until that was implemented to be honest. No one will play a game which isn't provably fair (Well.. Anyone with half a head).

Good luck!

I have just added provably fair verification  Use PHP snippet from "About FairDice". You can find roll details by clicking the "i" button in rolls history. You can also change cliend seed by clicking "Set client seed" button.

I think I have some trouble accessing your site. It's loading forever.

[avencard]

It should be fixed now.

Nope, doesn't load.

[avencard]

Sometimes it gets overloaded. I will move it to the new server tomorrow.

Does this mean you will make the method available soon, or you will implement it soon?

From your site.

<?php
$server_seed = "SERVER_SEED_HERE";
$client_seed = "CLIENT_SEED_HERE";

function str2int($str) {
   $int = 0;
   foreach (str_split($str) as $char)
      $int += $char;
   return $int;
}

mt_srand(str2int($server_seed . $client_seed));

$roll = mt_rand(1, 6);
echo "Roll result is " . $roll;

How is this provably fair when the mt_srand and mt_rand are pseudo-random and not guaranteed to give the same output on every system?

Also neither the "server seed" or "client seed" are ever shown to the user.

dice64, I have already implemented this. You can check client/server seed of roll by clicking "i" button on rolls history.

mt_rand will use seed provided using mt_srand. This is system-independed and will always return the same result.

Thanks- I enjoy trying out new games

Everything on the site was loading and working properly until I received the credits. However, after I saw them in my account, the stats portion of the site stopped loading properly, and i bet 40 satoshis, 4 different times, each came up rolled as a 1, and nothing was ever subtracted from my funds. Upon trying to reload the webpage after this- the site no longer loads at all.
Could be down temp for something but just letting you be aware of that issue.
Hope to continue testing this soon

[edit: working properly again for now ]

The mt_rand function uses Mersenne Twister to generate its output.

Caution: Mersenne Twister is basically for Monte-Carlo simulations - it is not cryptographically secure "as is"
http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html

Also, you dont show the user the secret seed, or its hash before the bet is placed. So you're free to generate any result you like, by creating any secret that matches the output you want.

[avencard]

dice64, you are right, I will add hash. Unfortunately my current server is not working good with such much traffic.
HallowIP, do not worry about it, if you always roll "1", it means that the server is overloaded, but your money is safe.
I'm sorry for troubles.

Let's try this.

After testing for a few minutes just a bit of feedback,

"Becouse fairness is a good thing"
You have a pretty big spelling error at the top of your page.

The results of the roll should update as fast as you can make it- I notice the balance changes after a second, but then 2 or 3 seconds after the results actually show up.
From my experience, and understanding a site like this success is weighed heavily on features such as instant results showing up. Like on Just-dice, the results are displayed nearly instantaneous and I think people generally appreciate and like that, and if it didn't have it, it's success may be a bit different.

Apart from that, another feature I think people would like would be a way to input the exact bet they wish to wager, rather than using the slider to pick a bet. Perhaps I wish to only bet 39 satoshis instead of 40? Just a thought there.

Otherwise, I like the site and I enjoy seeing a physical die on the screen.

HollowIP, thank you very much for the feedback.

To be honest, I'm not native English speaker  I will fix this..

This is good idea, I will do this!

And this will be done too.

You should have added it before you started, why would the server always roll 1 if it was overloaded? Shouldn't it raise an HTTP 503? Always returning a 1 shows that you've written some logic to change the result outside of the method you've already said.

Also, just from a single test, I can see you aren't using atomic database transactions.
