I think they "gambled" on the fact that no one would waste that much time to prove that they ARE cheating.........  well,  they lost that bet.
I think they assumed nobody would stop using the site because of this, and from what I've read in this thread, they won that bet.

Bitconnect tried the same philosophy.  It ended well for them,  they are still in the top 50 right lol.  I wonder how their rebrand is going that they had planned.

Actually Bitconnect isn't even on the charts anymore because they're not being traded anymore (well, only on one highly questionable exchange). Their rank doesn't exist because the value of their market cap is effectively zero.

In your sig it says,

"Watch me rape Freebitco.in 24x7 with my gambling bot"

I dunno, from the way you complain about things it sounds like you're the one being raped.

The closest number I rolled so far was 9995, but I guess that they have to "protect" the higher earnings since there are like tens of thousands of claims daily. Besides, it's free.

Makes sense...... unless you try to lie about it,  which they do.  They attempt to make it sound like there is an EQUAL chance to roll 10000 as there is with rolling 0.  But that just is NOT the case and it's been overwhelmingly proven by multiple people now which means their "Provably fair" claim can no longer be used since we now all know it's NOT provably fair as far as the rolls are concerned.  In order to be "provably fair",  there must be an EQUAL chance to roll ANY number that is within the given range (which is 0 to 10000 for freebitscam) and it must be mathmatically provable.  The fact that they dont acknowledge this now obvious cheating is what people like myself will bitch about.  In general, humans dont like to be lied to and they'll go to extreme lengths to make others aware of the lying going on.  It took me a YEAR of compiling roll results to prove this fact beyond a reasonable doubt without the need for the provably fair links.  I have so much data that its just blatantly obvious with no need to prove every single roll.  I can prove it just by sheer numbers of results that I've logged over a 1 year period for 3 accounts.  I think they "gambled" on the fact that no one would waste that much time to prove that they ARE cheating.........  well,  they lost that bet.  And if you've seen my posts,  you'll also see that I'm now one of their biggest critics also and I routinely point out all the lies that TheQuack and WetBackEars spews out.  They try to paint me as some troll hoping that no one will believe anything I say, but they can only lie for so long before it all careens off course and smashes into wall,  likely one thats got "Reputation:  Rekt" spray painted all over it.  They are going to try to "Rebrand" to wipe the accusation slate clean as well as get away from the google results associated with their name and all the cheating going on,  but that almost always fails anyway.

Although I did never check, I also don't believe that freebitco will do cheating. I never have seen such kinda complain and I personally win $20 couple of times. It would be better if TheQuin put his/her opinion here.

You guys might want to check this out:

https://bitcointalksearch.org/topic/rolled-won-00053btc-at-freebitcoin-5092067

The fact that the guy posted this in the Altcoin Discussion board makes me think that it is legit and not some conspiracy generated by the freebitco.in devs. I know its only a $20 win but nevertheless it goes to show that it does happen.

Pretty much the most unsettling thing about this particular dice site is that the house edge is considerably large... I don't know why people who accrued large amounts of bitcoin would use it when there's alternative with much better odds... yet they still do...

I'm talking about the free roll game.
Their system is provably fair, of course, but who's so stupid to save and check all the hash of every free roll? Me
My day job allow me to work on a computer so i'm able to roll about 14 - 15 times a day.
However, over the last months i managed to collect about 3000 free rolls, thanks to a script i managed to save every server seed hash, client seed and nonce right before and right after every roll, so i could check them later.

Most of them are fine, but 2 times happened that, after the roll, server seed hash was REPLACED with a new one, while nonce and client seed where still the same. This completely break their fairness, since replacing the server seed hash means that they are replacing the server seed and therefore they are changing our rolled number. Roll Eyes

Server seed hash never change unless you roll. you can reload the page, logout and login and it would be still the same.
I'm fully aware of freebitco.in's thread where people post their big wins.
Since the highest number i got was 9993 and since i never deposited any satoshi, my guess is that they apply this cheat just for the first 3 prizes (so from number 9994 to 10000) only to people who have never deposited anything.
I say so also because probability to win one of the first 3 prizes is roughly 6 on 10000, so 2 on 3333 on average and this cheat happened 2 times over 3000, quite similiar to their big win probability.

If freebitco.in want to follow this behavior to discourage people like me who just play free rolls and never deposit, that's totally fine but they should atleast be honest with their users and it should be written somewhere
To be honest there must be something in it, many time I rolled number above 9990 and when I was certain that I won , the number automagically changed to lower. I would not be surprised If only friends of developers and devs are rolling the highest numbers. Same goes to their weekly lottery, there is tendency that new account wins.

I don't want to believe that Freebitco.in would cheat their users for few bucks.

What you dont want to believe and what reality actually is are two different things.  Believe whatever you want,  but the facts speak for themselves.  Just take a look at the screenshots and you can see clearly that there IS cheating going on as far as Freebitco is concerned.  As I stated before,  the answer to why people report things in the "big wins" thread is VERY simple as I explained in my #2 theory (which isnt really a theory anymore as much as it is a proven fact).  The site purposely throttles the amount of wins it doles out.  It does this not only for free rolls,  but the lottery AND the multiply game.  These are proven facts.  Why people still think this site is legit is a complete mystery to me.

The below screenshots show that 9994 to 10000 are all missing.  This is simply NOT possible in this reality.  The chances of all of these numbers being missed IN ORDER in ~20000 rolls is so small that the HD of this forum's server couldnt hold the amount of 0's it would require in order to represent the probability of it happening in 0.0000...%  It's absolutely clear that these results are from purposeful SERVER SEED changing (which you have noticed in your own DB,  I didnt even bother to record them as they are not necessary to see patterns in cheating).  You can see that 0-10 have no problem showing up as results,  it's only the upper numbers that have issues even though they BOTH should have the same probability of being rolled.  You certainly do NOT see 0-10 missing IN ORDER like you do for 9994+
I have made over 18 000 faucet claims in 3 years and I haven't rolled 9994 and higher numbers. Also, any of my referrals also haven't rolled numbers higher than 9993. But I don't want to believe that Freebitco.in are cheating. How you can explain things which are posted in this thread?: https://bitcointalksearch.org/topic/big-wins-at-freebitcoin-1850855. There are hundreds of users who had posted proofs that they rolled 9998-9999 and several who rolled 10000, for example most recent winner of $200 -https://bitcointalk.org/index.php?topic=1850855.msg48648119#msg48648119. I don't even talk about 9994-9997 there is mathematically bigger chance to roll these numbers than 9998-9999, but we don't know how many user rolled these numbers. Offcourse, it would be interesting to know why server seed got changed for users who posted in this thread, but I don't want to believe that Freebitco.in would cheat their users for few bucks.

Disregard all the trolls saying that you were "Unlucky" or that your seed weirdness was "just a bug".  I have undeniable proof that the server seeds ARE changed.  I,  like you have compiled a MASSIVE db of free rolls and my screenshots speak for themselves.  You dont even need the verify links to see that the seeds DO change and I can even tell you for which rolls that they WILL change.  It's for any roll ABOVE 9993 as seen in my screenshots below.  This has been documented for YEARS but no one ever believes it because they are to stupid to realize that humans ARE indeed complete assholes and will cheat you every chance they get.  The reason you are seeing these server seeds being replaced are because of 1 of 2 reasons:

1.  You are on a bot blacklist
2.  (and more likely I think) The site purposely limits the amount of upper tier free rolls that it will allow which is COMPLETELY against the "provably fair" claim.

The below screenshots show that 9994 to 10000 are all missing.  This is simply NOT possible in this reality.  The chances of all of these numbers being missed IN ORDER in ~20000 rolls is so small that the HD of this forum's server couldnt hold the amount of 0's it would require in order to represent the probability of it happening in 0.0000...%  It's absolutely clear that these results are from purposeful SERVER SEED changing (which you have noticed in your own DB,  I didnt even bother to record them as they are not necessary to see patterns in cheating).  You can see that 0-10 have no problem showing up as results,  it's only the upper numbers that have issues even though they BOTH should have the same probability of being rolled.  You certainly do NOT see 0-10 missing IN ORDER like you do for 9994+

You will also observe the SAME result if you try to use the "jackpot" in the "Multiply Game".  You'll also observe the same result if your "profit" from any "Multiply Game" bet is over 7x of your original bet OR if your profit is exactly 20BTC.  The site clearly has limits in place that are NOT disclosed and are purposefully hidden behind a "Provably fair" claim which is difficult to prove unless you compile data like I have.  The ONLY part of the site that can make a decent "provably fair" claim is the LOTTERY which uses a BTC hash for the Server seed,  but with the site's behavior in all other rolls,  I wouldnt put to much stock into the lottery WINNER actually being a real person as very very few of them actually claim to have won.  There have only been a handful seen in the forums which is in line with all other manipulations that they do that would support a theme of limiting what they will allow to be won.  So even though the lottery is technically "provably fair".  The actual WINNING ID/id's may indeed be changed by the server to someone that doesnt actually exist (this is why it's not possible for people to see if an ID exists or not,  if they did this,  it would reveal the ID changing of the lottery),  thus allowing only a few people to have actually "won" anything at all.  And thats IF they arent already "in the hole" from the multiply game.

Also notice that this isnt really limited to just 9994+ either.  Notice of 0-10 are so plentiful that they take up all of my mysql results.  But for the 9000+ rolls,  it sinks all the way down to 9978.  This is CLEAR evidence of my #2 theory I think.

This site is such an obvious scam it's just disgusting.

For me, 7631 free rolls played, and best number i got is 9988. If numbers have the same probability, I should draw 9994 or higher 6*7631/10000=4 times already.
It's obvious, as said earlier, that all numbers don't have the same probability of being drawn, and I think it has something to do with the calculation method.
I precise I've deposited on the site (i have no more captcha).

Provably fair means, for them, that you can check the way number is calculated. But the calculation isn't just a rnd()*10000 formula, but is much more complex, so that no one can prove it's made to draw mainly 0-9984 numbers.

This is not how it works.
If you have 7631 rolls, then every time you have a 6/9999 times to hit 9994-9999, the expedition is a different thing.
It's a complex calculation from variance and expectation value, you can find more info here https://en.wikipedia.org/wiki/Variance.

This is the reason why someone is lucky on variance and win the lottery with 1 ticket and someone with millions of tickets, never wins.
Just only because it's improbable it doesn't mean if you will roll the coin 50 times you will not have 50 times head.

sooo they claim to have 17 million users

sooo if they have daily active 100k users which make at least 1 free rolls they should pay minimum 2.000 USD  daily + other rewards which are quite significant in long run



sooooooo im pretty sure that no one will give away 2k USD every day totally almost free


even if you earn quite a lot from multiplier game  2k  every day + other rewards are too good to be true



especially in bitcoin world Smiley heh Wink

I have to point out that the first prize have a winning chance of 1 every 20.000 and not 10.000 because of the way the mechanics are made (every number below 9999,5 gets rounded to 9999).
Anyway the difference is still larger, 12.5 times, than it should be so this is another proof against them
Thanx for you manual counting lol

You should probably move (bottom-left) this to Scam Accusations.

I've often wondered if they're legit, based on the average cost per faucet claim:
1 number pays $200
2 numbers pay $20
4 numbers pay $2
8 numbers pay $0.20
100 numbers pay $0.02
9886 numbers pay $0.002

I've always wanted to know if they really pay $271.37 on average for 10000 rolls. And if so, why don't they just pay $0.027 for each roll? They'd have the highest paying faucet, while it would cost them the same amount in total.
Because they choose not to pay the average amount for each roll, but made it a jackpot system, cheating would be possible and largely go unnoticed. Especially if they only cheat once every few thousand rolls.

Based on the odds, I would expect one $200 winner for every 2 $20 winners.
I did a (manual) count on pages 5, 10, 15, 20, 25, 30, 35, 40, 45, and 50 on Big wins at FreeBitco.in:
I just won $20 at FreeBitco.in! 116 times
I just won $200 at FreeBitco.in! 2 times
I probably miscounted a bit, but let's round it down: winning $200 is 50 times less likely than winning $20, and that makes the difference 25 12.5 times larger than it should be.

Ok, I was not believing it in the first place, but I noticed the same thing using my script.
I was rolling a lot the last several days to finally cash in all my reward points with 1000% boni.

Today around 5:42 UTC I rolled and the script alerted me!
The hash of the server seed before the roll was "e0dae012326019db972797e41a3edee109d0b9c8859c704ac9f984fcb3251729".
After the roll the hash of the pervious server seed was "81c07a9aba1b10da9a757d339a3e05a5cb7466d13c0c8abf3e72bb3b9f85aa7e".

It is obvious that the server seed hash changed and therefore also the server seed changed and the result of the roll changed!
The server seed of the second hash is "7d65304764de4888be843be666980845aa129f8b95eb490e66aa42017b080eb0".
My client seed was "21aeb50085fe13a3e35f1052acb0f91fdeab588264f2fc64462fd071b0fcae6e".
The nonce of the roll was 3658.
This leads to a 1507 being rolled (https://s3.amazonaws.com/roll-verifier/verify.html?server_seed=7d65304764de4888be843be666980845aa129f8b95eb490e66aa42017b080eb0&client_seed=21aeb50085fe13a3e35f1052acb0f91fdeab588264f2fc64462fd071b0fcae6e&server_seed_hash=81c07a9aba1b10da9a757d339a3e05a5cb7466d13c0c8abf3e72bb3b9f85aa7e&nonce=3658)

I will definitly report this to TheQuin and ask him about the server seed of the first hash, because what I really want to know now is what the result would have been with the real server seed!

I know that there is no way prooving that I did not fake these numbers, but I cannot think of a way to do so.
I attach an pdf with all the hashs recorded by my script to this post, so that you can see I actually recorded them. The upper ones are the most recent ones and the changed ones are marked red.

Hmm, this sounds interesting, but I don't want to just believe you.
I have set up a small script now which automatically compares and records the hashes before and after the roll.
If the phenomena is a s rare as you say it will take some time til I get a result.

Pure probability and statistic laws say that 14.5 out of 10000 results gives you one of the 4 highes winning classes which means on average every 700th roll will be of one of this classes.
I rolled now about 3300 times and had 3 results in these classes. On average I should have had 4.7 which is pretty close.
Statistically it could just be bad luck, but I'm curious what my recors say after another 1000 or more rolls.

I would suggest reaching out to them and inform them of your findings and their response will tell you if they are being sly or if it is a genuine bug.  They have so far seemed legitimate and one of the longest faucets around, I hope it's a bug they're unaware of.
