https://i.imgur.com/VQFW4Se.jpg I know it's provably fair, but this really makes me think if there is any "special" mechanism beyond the screen. This is not the first time happens to me, also there are another things similar to this...

It depends on the provably fair method used. Some implementation of some sites are actually not really complete and allow the casino to still cheat in certain ways. However I am not sure what site that is and therefor I do not know if that site has a good implementation.

Well first thing to realize is that provably fair does not mean the casino cannot cheat. It only means you as a player could detect cheating if you take the time to verify the outcomes (and if the implementation is correct.) I had a quick look and they use "verify per roll" method, which means you should verify the outcome after each bet. They DO seem to use a good implementation for the "per roll" method, especially since they generate a random clientseed every bet in the browser. The "verify" button only checks on their site so cannot be trusted, you should manually verify the rolls by this: 1. Before bet: Copy " Hash (Result + Secret)" on the right side of the site (and ideally change your client seed.) 2. Make your bet 3. Copy " Result + Secret" into: http://www.xorbin.com/tools/sha256-hash-calculator and check if the result is the same as the hash that you got before the game (and therefor really true.) 4. Combine your client seed and their result (if more than 36, it will start from 0... so 18+24 = 42 = result 5) You now know that they gave the hashed result before the game already (since you checked the hashed) and that the result is correct PS, you can read my article http://dicesites.com/provably-fair for a better understanding. And a lot of dice sites use a different implementation with a nonce. IMO that makes it faster for the player to verify the results since you don't have to verify every bet. Some examples that use this: PrimeDice, JustDice, PocketRocketsCasino, BitDice, SafeDice and many others. PS2, the odds for you to lose 3 or more times in 7 bets is 0.47% which is not that crazy. To lose 3 or more times in all 16 bets is 5.21% chance of happening.

This is not the first time happens to me, also there are another things similar to this... If the site does not allow you to change the client seed, then it is not truly fair. That client seed is a huge part of the key in making sure the server(house) can't cheat the customers. Provably fair is one of the biggest contributions that bitcoin has made to gambling.

Thanks your explanation, i will take time to read this, and also consider to play the dice game PS, i am horrible at Math, i think is time to retake the books...

I was reading the reddit article/post below the other day, and it seems even the "provably fair" system can be a false sense of security for gamblers more then anything else.
Post is here: http://www.reddit.com/r/Bitcoin/comments/1frm4x/provably_fair_by_bitzino_not_provable_with/
I'm NOT a coding expert, but if this post is true? my guess is most casinos are using it to bypass the "provably fair" system.
Unfortunately when money is involved, extreme GREED always follows.

Keepinquiet an user here in bitcointalk has been investigating different casino sites that use ''provably fair'' but in a way they could cheat, he already exposed a few of them and it seems like at least 50% of all the casinos advertised on this forum dont have the provably fair system implemented how it should be, however if the site did it right, there would be no way for them to cheat as far as i know. I asked about this not long ago and people told me that there was no way if the system was really provably fair. Here is the link: https://bitcointalk.org/index.php?topic=1070228.0

NLNico is an expert person here to explain about this what the wrote in that article because he has much knowledge about the provably fair mechanism, in my point of some online casinos using most advanced method to cheat the players and there is possibility to be get cheat by them while playing there.

Yeah I figured this was the case, but I thought the number would actually be closer to 90% :-) The fact that it's only 50% actually not too bad IMO ...lol Very interesting topic though.

i know the perception can lie at some point, but while playing the games on these sites i just feel that some point there be the cheat regardless provably fair or not, because the game always happens something that could happen but should not be so frequently.
As an example, i played roulette, and it usually happens to result a continued red result, while i am betting on black and vice versa. If this happens just once for a while i think it's ok, but this just happens so usually that caused my wonder...
i think only the game could play is dice game...

I know it's provably fair, but this really makes me think if there is any "special" mechanism beyond the screen.
This is not the first time happens to me, also there are another things similar to this...
Every gambling site claim they are provably fair. I also don't know how to know they are not liar.

haha i know how you fell beleive me. in the end you will never know if all those sites are ''provably fair'', even if you win you will have that in your mind. thats the problem, whatever you can read at reddit or somewhere you will never be 100% that is ''provably fair''... Unfortunately when money is involved, extreme GREED always follows. [/size]

I don't know what is this site , but you have to study their system there is a possibility that they are playing with the results if for example you couldn't change the client seed just do some researches about the site , you may find some people talking about the same thing but we can't judge the site from this picture since there is a possibility to get the same number three times in a row I got the same number two in a row playing dice which has smaller possibility of hitting the same numbe 3 in a row playing roulette so it happens , but u need to check the ( provably fair ) your self to ensure that

Somehow I think there might a way for casinos to bypass the " provably fair " system. It is unbelievable for you to lose a few times in a row when you bet almost all the numbers on the table.

This is what happens, too. And actually we can verify the p.f. system, however we are not going to do this over again and again while playing, i think the thing i will consider to do is intend to change the client seed at every play ? Is there any possibility to cheat beside the user dont change their client seed ?
