Also 95%+ of the tickets in each round are given out for free to users for free plays and referrals so the prizes for each round mostly come out of my pocket. So there isn't anything that I could gain by rigging the system because it's not like the lottery actually makes any money. It's just a bonus to encourage users to keep playing.

Just leave it as it is. 99% probably wouldn't even notice the 'provably fair' option if there was one.

As you said, earnings comes from your own pocket* and lottery is an extra option, so there's no real reason for it to be provably fair. I wouldn't worry about that, unless someone proposes a doable solution (where's Dooglus when you need him Wink

)

* Mostly out of your pocket. IIRC, it's possible for someone to deposit his own funds and use them to buy tickets (I'm guessing that doesn't happen very often). For that reason it would be good if lottery was provably fair.

I am fine with that, and the code being posted... the question with most of these Lottery games are... How can we be 100% sure that it's that code being used, when the

winners are drawn. You could have a valid and legit code, used for proof and a separate manual method to select the winners you pre selected? This is how most rigged lottery

systems work. There is no verification for the users that the winners are drawn from the same code, they give as proof. I am not saying you are doing the same, because you

have a lot to lose, and the 1 to 2 BTC you would score from this in comparison to your total profit you get from this faucet, is but a mere drop in the pond. I would not risk

losing my reputation and a great profit from the site, over a rigged lottery. Roll Eyes

Have you thought of any method to verify winners? Something similar to the way you prove the

PROVABLY FAIR HI-LO game or asking some reputable person or company to verify it?

B.t.w congratulations on reaching the 7 BTC mark from donations from this faucet. It's awesome what you doing. Wink

I understand the concern and would actually like to put in a provably fair system in place because many users have the same concern with the lottery. That being said, I still haven't figured out a way to make it provably fair because the total number of tickets changes every week. If the total was fixed, winning numbers could be pre-selected and hashed before the round starts to make it fair. However, in the current state I do not have any ideas for making it provably fair but am always open to suggestions.

Only other way would be to have a lotto type of system where the users select 6 numbers but there are many referrers who haven't logged into their account for over a year but are still getting paid and accumulating tickets in each round. It would be unfair to ask such users to have to log in every week.

Also 95%+ of the tickets in each round are given out for free to users for free plays and referrals so the prizes for each round mostly come out of my pocket. So there isn't anything that I could gain by rigging the system because it's not like the lottery actually makes any money. It's just a bonus to encourage users to keep playing.

Let me try to explain how it works using the code that is used in perl to select the winners. There is a database table created for every active round containing the user id's and the corresponding number of tickets they have in that round. Then once the round ends, 2 arrays are created - @userids containing all the user id's and @tickets containing all the tickets. This is done by going through the table record by record and using the following code:

Code:

my $user_tickets = $db->SelectARef("SELECT userid, tickets FROM lottery_active_tickets WHERE round=?", $current_round);
foreach (@$user_tickets)
{
push @userids, $_->{userid};
push @tickets, $_->{tickets};
}

Then after these 2 arrays are created, the following code is used to pick the winners:

Code:

my @winners = ();
my @winner_tickets = ();
for (my $i=0; $i<10; $i++)
{
my $total = sum @tickets;
my $rand = int rand $total;
my $selected = 0;
my $limit = $tickets[$selected];
while ($rand >= $limit)
{
$selected++;
$limit += $tickets[$selected];
}
push @winners, $userids[$selected];
push @winner_tickets, $tickets[$selected];
my $removed_userid = splice @userids, $selected, 1;
my $removed_tickets = splice @tickets, $selected, 1;
}

Once a winner is picked, their userid and tickets are removed from the arrays and the loop above is run again to pick the next winner until all 10 have been picked.

Thanks for the clarification.I thought its like usual raffle tickets with specific numbers.

The weird thing about the draws are the results. People who buy the least tickets win the most money. Only one or two people who spend a lot of money buying lottery tickets won

any of the Jackpot prizes. It should be the other way around... there should be lots of people who buy lots of tickets winning these prizes. I was under the impression that the more

tickets you buy, the higher your chance to win the bigger prizes or any of the prizes for that matter... but the results of almost all the draws reflect the opposite. hmmmm.... Huh

That's true of course but(i'm considering the latest round) when you have a total of 11m of tickets also if you have 90k(the person that won the 4th prize) tickets you still have only less than 1% of probability to win the first prize.

We get a lot of emails about this but people don't realize that because the tickets are picked randomly, even buying 100k tickets only increases the chance of winning and does in no way guarantee a prize. It's the same as any other lottery - even if you buy 100k tickets in the Euro millions for example, there is a very big chance that you would not win anything. 100k tickets is less than a 1% chance of winning.

I just need some clarity as to in what way'tickets are picked randomly' please....Do these collected tickets have specific numbers assigned to them?
Thanks

Out of the 20 draws only 6 people won the 1st prize, bought more that 1000 tickets... The rest {14} draws was well below 1000 tickets... weird?

The trend continue as you go to the 2cnd and 3rd prizes... most of the lowest paying prizes are awarded to people who actually buy more tickets. Why would that be, if the site

encourage people to buy more tickets to increase their chance to win?

Abyone know a strategy to make more satoshi with multiply game?
I will use this faucet because I can gamble my satoshis to make more.

You should try and google tricks, but in the end you gotta be really lucky on one bet.
I believe its like a 49.5% chance on doubling with 1% house edge.
