how this can be probably fair i did not think so Cry
http://abrr.ir/wp-content/uploads/2016/12/roll.png

That's unlucky but it happens. The longest losing streak I'm aware of was over 30 losses in a row at chance of ~50% (payout rate of 2.0).

You posted a streak of 20 losses at 3.0 payout, so your chance in each bet was only around 30% (not sure what's the house edge), so it's nothing unusual.

ps. it's called "provably fair" (not "probably").

Wait... What?
why does the site block you from claiming when the server time transitions from XX:59 to XY:00

"the session has expired"

Got that too in a quite often frequency, but I figure that it will be faster to reload the page than to write a complaint here since reloading literally took less time

I have asked many times for suggestions on how I could  make the lottery more fair but have yet to receive any concrete suggestions on how it could be done. I am always open to suggestions and if someone can recommend a provably fair way to draw lottery tickets, I would be happy to implement it.
Why you doesn't answer from support-form messeges on freeebitco, not answer on PM here? I wrote you twice through support-form and here once about blocking my IPs on your site. Are You ignoring users or just me?

Still n1 faucet ! Wink keep up the good work

Fully agree it's "numero uno" since the beginning.

BTW: I have received 0.05 BTC reward for my hint about lottery fairness (few posts above) and I bet there will be better reward for providing functional principle how to make it 100% provably fair so don't hesitate to bring up your own idea about this topic.

Thank you wetsuit.

Thank you for the suggestion, it is something along the lines of what I was planning to do. I was looking for a way to do this without having to store 70-80 million ticket hashes every round due to the load it would put on our servers, but it doesn't seem like there is another way.

The method is pretty good, bit it still doesn't solve the problem of me cheating by creating fake accounts and tickets for them so that the hashes of these tickets fall into the positions of the winning numbers. I doubt there is any way to make the lottery 100% provably fair due to this but this is still a much better implementation that what we currently have.

I'll add this to my to-do list and should be implemented in a month I hope.

Maybe increase the price of each ticket by 10 times (to 0.00075 USD worth)? The free tickets given away in free rolls could be changed to given away by chance (e.g. if rolled lower than 2000/greater than 8000 than give 1 ticket). Assuming 100 byte per ticket data, 7M tickets would be only 700MB in size.

Or make the lottery blockchain-based: Order the tickets by some method (maybe the order of users acquired them, or by user ID), and make use of a block hash (use the last digits, the first digits is always 0) to determine the winners.

P.S. Why not make freedoge.co.in have these features too?

Its 70 to 80 mil tickets every month and one entry would be about 100 bytes so 7 GB. However, the problem is not with just storing the data - that is the simple part. Looking up ticket numbers by user id or sorting them to do the draw is what would take a huge amount of processing power so I'll need to isolate this from the main servers and set up a separate server just for doing this so that it does not impact the rest of the website.

We currently store a bet history of about 700 million bets at any time and for that I have had to set up a separate server, this would be something similar although smaller but the sorting would consume resources which is something we do not need to do with the bet history.

I don't think increasing the price would be viable at this time, it would reduce interest and also distribution for multiply and referrals would become complicated.

The main problem is what wetsuit pointed out already. He can make bunch of fake accounts and assign them another 70 mil tickets providing him 50% chance the winner will be one of those. I think there is no way how to make this 100% provably fair other than using third party to assign and check the ticked fairness.

There would have to be a completely different way of tickets distribution. Something like every ticket to be hash of data linked to account (where the ticket come from: bought, hi-lo game, freeroll, ref. hi-lo ... ) and all these data would have to be public. I guess this is impracticable.

To eliminate fake account creation would require complete user identity reveal and again to publish them (the IDs, names, phone nrs.) so everyone can check ... this is even more impracticable/unacceptable.

I run out relevant options but glad we have open a discussion because solving this issue would make the site much more attractive ... perhaps some user will find a brilliant solution how to.

Have you ever received any suggestions? I don't want to read through hundred pages so here's my silly idea:

- let every user to enter an unique and non-changeable seed linked to their account
- at the beginning of round publicly announce 10 numbers between 1 and "expected number of tickets" ( rather much more )
- make hash for every ticket: userseed + lotteryround  + nonce (nonce to be the users ticket number)
- at the end of round put all hashes in alphabetical order (assign each a serial number) and publish the list
- the numbers given on beginning denotes the winners ( if some user would win twice then the seed next in order counts, if expected number of tickets exceeds the real count then turn over and start counting from beginning )

I'm not programmer ... just trying to apply common sense but I'm almost sure there will be some catch I didn't realize. Feel free to educate me.

Slava Ukraini!
I saw that minimal Doge payout was 600 dogecoins. But on payout day it's increased to 700 dogecoins. And I see it not the first time. Why it happens?

Yeah, it seems to happen to me every couple weeks. But the good thing is that wetsuit always fixes it promptly when I bring it to his attention. Annoying that it happens, thankful it's resolved quickly though.

Sorry about that, the whitelists reset when I make a change to the bot-detection tool, but your rewards should be fine now.

Hey wetsuit, any news on that touted announcement from a couple weeks back? You piqued my interest, but then there hasn't been anything since then. If no news, do you have a timeframe of when you expect you'll be ready to announce?

I got delayed with this because the plan changed after I posted about it here. I ended up increasing the scale of the project (invested close to 500 bitcoins now) so it is still on track and I hope it should be ready for users within a week.

Ah thanks. I thought you said I had been whitelisted at one point, so inwas surprised about having my tier one halved again after that. But glad it's resolved again now.

That's a ton of money to pour into a project. I can't imagine what it would be, other than renting a bunch of server capacity to host some type of mining operation or something along those lines.

Continuously losing my all faucet amount on stupid lottery system.

Then stop.

Improve the draw system put something provably fair and give the link to verify the winners.

Feel free to share how to implement provably fair system to lottery and I'm sure wetsuit will seriously consider it.
I agree with pawel7777 if you are losing then take some time and stop this because its not good for you wetsuit is one of best admin if any one have good idea for this lottery then hope he will try to implement

The admin (wetsuit) is always ready to provide incentives to people who want to help him with the site. You can try building your own provably fair system and ask wetsuit to implement it on the site for an incentive - instead of complaining of losing faucet money on lottery.

Moreover the users who are winning are asked to post about the wins (Just like I did with my 200$ win on this forum), however most of them are not willing to tell or are not English speaking and hence shy away and never bother to post here.
