based on your provably fair system, that bet should be a winner because of 9 and 7 both being odd numbers unless you are trying to cheat to get free money from players on your site?

No cheat!

It posted on site:
"Sorry, temporarily this provably fair system not work. After hacker attack, we create new provably fair system.
Game works well and you can play now! Good luck!"

we soon add new provably fair and see it.

no cheat? if you are not cheating your players then can you show us your new provably fair system on how it works? and i wonder how could the hacker hack your site and provide winning hashes since it depends on the blockchain

no cheat!

thanks a lot Chemistry1988!

Assuming what you said on your provably fair page (https://web.archive.org/web/20160506034612/http://rollincoin.com/provably_fair.html) is true, your game is faulty. Players can create a transaction, choose not to broadcast it, check if it wins or not, repeat the process and broadcast only the winning transactions to the network.

you said: "your game is faulty"

What you mean?

It seems to me that you thought your players (or in general any bitcoin users that create a transaction) have no control on their TxID, which simply is not true. If you have no idea about my second sentence in my previous post, you'd better do some research on how the "createrawtransaction" and "signrawtransaction" APIs can be used to create a transaction without broadcasting it.

Cheater has generated win hash transactions use "createrawtransaction" and "signrawtransaction" APIs

Personally without verifiction I wouldn't be betting large sums on this website until the dev clears this up. Especially after the hacker attack.

To be more exact, I only pointed out the problem in the provably fair scheme the site uses (used?) that players could do what I described to make sure their bets will win. I don't know if players have done that or not.
It is why other onchain gambling sites such as luckybit have to use a daily secret (set by the site, hashes of the secrets revealed in the beginning, actual daily secret to be reveal after the end of that particular day) together with the bet TxID to determine the result of the bets.

Note to players on the site: The site is not provably fair until the site has announced their new provably fair scheme.

 That is not true you are a liar. You site says if you get 2 odd numbers and I have 9 7 so I should get my reward.  You are a scam.

You are scamming all of us. You scammed me for 0.004BTC.
Changing the provably fair system without describing how it works now is counted as cheating.
At least now mention on the site that how are you calculating if the bet wins or not.

I think what you are trying to convey to your members is quite not right . You said provably fair system is not working , and you are creating a new one, what players are asking is to tell them
1. what is that provably fair system you are creating
2. what is the current provably fair system .

And also I think it would be good , if you close down the site for maintenance till the new provably fair and open it once it is fixed and implemented.

Wins pay after 1 confirmation.

According to this , you are still using the old provably system right ? I think it's better if you hire someone who can convey the info in proper manner to the users. I have a feeling you are honest . PM sent regarding support .

Thanks admin.

Could you make bet for x5 x10 x100 ?

[finishedgrey]

So the offer still available? So if I bet then I won, should I claim my winning reward or I lose then they will repay my loss?

[arseaboy]

so i loss some update from here what happen to OP? did he already replace the fair system, I think OP our mate is correct even if this site is fair we still needs to prove it, and while you are still working with your new system you can close this site temporarily for maintenance and re open again to show that you are really working and listening to your players. good luck mate.

Players here are certainly not talking about winnings not paid . They are of the opinion that the provably fair system is not working . They should be some way to determine the winner right ? But it is not clear , what is that way to determine the winner. So they are just asking to make provably fair system which is currently being used transparent . We can see all the winnings being paid .

so i loss some update from here what happen to OP? did he already replace the fair system, I think OP our mate is correct even if this site is fair we still needs to prove it, and while you are still working with your new system you can close this site temporarily for maintenance and re open again to show that you are really working and listening to your players. good luck mate.

Yesterday he told me , he is working on the new provably fair system and it will be implemented soon . He seems to be a honest guy , just a bad luck . Hackers hit his site . Hope he comes out of it and the site is back up.
