Technically, no site is 100% provably fair - at any point the owner can shut down the site and run with the money - and PVP is difficult to make provably fair, since there are many ways that the owner could cheat. However, the current provably fair system on this site seems particularly weak. As mentioned, the bet ID could be deliberately chosen to favour one player, and because the random increments are within a particular range (judging from the shown screenshot, I'm guessing in the thousands?) it would be trivial for a player to run some code which figures out what the average of their next few thousand rolls would be, meaning they could challenge high/low appropriately and have an advantage compared to a typical player.
I don't remember it completely, but Primedice's PVP used a system where both rolls relied on both seeds - $player1.$player2 for player 1's roll, $player2.$player1 for player 2's roll. Something along those lines would be an improvement, though there would still be issues if the owner was playing and could determine the opponent's seed in advance.

There is nothing stopping owner of the site to claim this promo bonus with fake account, since theres no real transparency here ?
If this is only bitcointalk promo, why not make a rule that username must be the same as on site.
And add info who is leading with most BTC , that board you now have there is useless info.
Just my opinion.

hello , i cant sign in
im sure that is true username and password but still can not , how to get my account back ?
When you sign up you are asked to enter a username & e-mail address; your password is automatically generated with a complex 7 algorithm and sent to your e-mail address; you are then free to either use it as your own or change it from the profile page.im sure that is true username and password but still can not , how to get my account back ?
Am i missing something or is there an option to randomly assign two players interested in PvPing or atleast show a list? If not, take this as my suggestion.
Not random, you enter your bet value, choose the amount of games you want to play (our version of autobet I guess), then click "invite user", everyone capable of making your wager will show up in a list; simply select a player and if they accept you enter into a game.I didnt recieved any email from your site regarding my password so i guess you have to fix it
Username is gampher can you pls manually email me with my password?
I think displaying the biggest bet is not that relevant, You should display who is leading the game instead.
Unfortunately as this is a limited time promotion we decided not to dedicate to many resources to it; that includes brain storming for nice ideas like this.I may post the results of the current winners here every day or so.
i have tested your site.
I open 2 account with yopmail, and get the 0.04 on each of them. Yolo with one of them and lost all. I will not gamble the other one, i was testing the site but don't found bugs.
The give away is looking nice, good luck with your site.

Hi Jamie_Boulder, i keep looking in your site and found something weird.
I was taking a look to your provably fair system, and i see the bet result is based on the Bet ID. and when i take a look to my bets id i found this:
http://i61.tinypic.com/2wew2ew.png
160075 Totoro 2015-05-20 09:20:34 0.04000000 PVP:Lo-Dice 55
159870 Totoro 2015-05-20 09:20:10 0.04000000 PVP:Lo-Dice 26
and i ask my self... how did 9 users roll 205 bets on 24 second? Then i take a look to all users bet and saw this:
http://s11.postimg.org/tjvmjqgzn/pr2.png
The Bet ID give big jumps, and since the provably fair is based in that number, that makes the site unfair. And i will tell you why;
Code:
while (user-A win)
then;
BetID=BetID+1;
done;
If you give a consecutive number for the Bet ID, that will make your site fair for me. I'm not saying you are cheating there, i'm just sharing my point of view, i don't know why that BetID number give that big jumps, but i would like to know the answer.
And i found other problem in your site:
You dont have a captcha in the Contact tab. with the next code for IMacros i can auto send a message:
Code:
VERSION BUILD=8920312 RECORDER=FX
TAB T=1
TAG POS=2 TYPE=LI ATTR=TXT:CONTACT
TAG POS=2 TYPE=A ATTR=TXT:CONTACT
TAG POS=1 TYPE=INPUT:TEXT FORM=NAME:contactForm ATTR=NAME:full_name CONTENT=Test

TAG POS=1 TYPE=TEXTAREA FORM=NAME:contactForm ATTR=NAME:comments CONTENT=test1111
ONDIALOG POS=1 BUTTON=OK CONTENT=
TAG POS=1 TYPE=INPUT:SUBMIT FORM=NAME:contactForm ATTR=*
Hope you take this as constructive comments, i really wish you the best with your site.

Gurbar leading the Hi-Scores with the highest bet made so far.
(screenshot sent by user).
(screenshot sent by user).
I think this high-scores leader board with highest bet is not really important to be announced since the prize will be given to anyone with the highest balance.
So, is there any ways to see top 10players with highest balance?
one more question : since you said there will be only ONE winner, so what will happen to other players who still have have small balance at the end of this tournament? Lets say user "A" win the main prize with 5BTC and there is user "B" "C" "D" "E" "F" with 0.5btc each, will they able to withdraw the 0.5btc or will you remove their (B C D E F) balance?
