Nice raffle site.

I'd suggest that you just give prizes for the 1st winner while jackpot is < BTC 1.0

If it's > BTC 1.0 then prizes should also go to 2nd and 3rd...

Is there any plan in turning the lottery provably fair?

Cheers!

Hi Financisto,

Thanks for your comment!

About the prizes:

Our lottery is financed through the ad-profits on the site. We also throw in all the earnings we make from testing faucets and referrals. The prize volume you mention is far out of our financial capabilities atm

We made the lottery for the community and we do not want to focus the payouts on single players. We think it's great to spread the prizes over multiple winners to increase the odds for every player to win something more frequently!

About the provable fairness:

Well, we thought about this, too. However, to make it REALLY provably fair we would have to change a lot!!

The lottery works like a "real" raffle. So while the ticket booth is open, any claimed ticket only has an index number. When the raffle ends, a random generator picks a number from the index, prize by prize. This cannot be made PROVABLY fair as the winner is only determined when the prizes are picked and thus there is no hash or anything to prove we didn't tinker with our random generator.

The player's ticket choice on the other hand COULD be made provably fair because the rewards behind the choices are determined through random generation server-side before the player makes his pick. Then again, we would need to display a lot of ugly hashes just to prove that the tickets which didn't even cost anything were given fairly, and really who is going to sit down and solve the hashes to check on us. Plus, again, we could always tinker with the random generator to begin with.

We try to make things as transparent as possible, but we also don't want to make it too clumsy and bloat the interface. If you have a good idea on how exactly we could make it more provable we will thankfully consider. If you post HERE and give us your player ID along, you're in for a small reward!

Anyway, our lottery will always be free and if the audience grows and ad profits grow along, the prizes will increase proportionally with it.

I guess you just have to trust us for the moment

So long, good luck in the next drawing!

keep up the good work fraenk *rum for you*

[fraenk]

thanks to those few who have voted already!!

for those who are yet undecided... consider, that a longer raffle also means more registered players per raffle and as the rules on the page state, this will encourage our prize bit to draw 4th and 5th , 6th to 10th winners and so forth, keeping the odds per player fairly even in a longer raffle!

ultimately, longer raffles will mean more prizes!

+1 for the trusted lottery! If you use CoinFaucets you can make it even easier to be sure you hit the lottery every 30 minutes for maximum chances of winning!

I voted for "unchanged". Much better chances of winning if there is a daily drawing of the winning tickets.

I voted for "unchanged". Much better chances of winning if there is a daily drawing of the winning tickets.

not neccessarily, we currently have just close to 200 players in the 24hr raffles.

once more than 100 players enter a raffle, a 4th and 5th winner are picked additionally.

if we had more than 200 when the raffle ends, there would actually be a 6th to 10th prize also... from our projections we would be spending slightly more on 48hr raffles, while still having 10 winners for every two days....

unless of course, we reach the 200 players each day, which is not too unlikely also... then the 24hr raffles would pay better!

I voted for "unchanged". Much better chances of winning if there is a daily drawing of the winning tickets.

Theoretically they'd have the same odds/income over time though. 1/2 the chances but 2x the reward should over time even out. The difference is doing it daily would benefit those that join every single day more than those who can't.

Yay! Now you just need to make a small change to the drawing script:

if ($name != "ranlo") drawAgain();

Thanks in advance!
