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.

You are welcome !

Yes you can find this miner version and download it here : https://cryptomining-blog.com/460-download-cgminer-3-7-2-with-gpu-support-for-windows/
And yeah its only worth to mine scrypt algo based Coins with Asic Miners like the Antminer L3+ and other Miners.
But for testing and how the stuff is working you can try it , but its worth more if you mine some other Algos with the GPU.

Its not profitable to mine with a gpu the scrypt algo anymore but yeah its some kind good learning to figure out the stuff and how it works !
For scrypt mining with a GPU you need the CgMiner Version 3.7.2  thats the latest version of it where its possible to mine scrypt with the GPU.
In this version of the cgminer there is already a scrypt-mining bat file and you just have to modify it for you or just have to insert the pool and workername.
