^^ If max number of tickets per player is set, a whale only needs to buy several of them in order to divide his 10 BTC bet.
It works like real life: "Offline" lotteries work that way too...
If that whale bets 10 BTC and loses (and it's possible), that's gonna hurt...

I think just a bit unfair like last draw where someone deposited 10Btc and won. Only those who can deposit higher amount has the high chances of winning and if you dont have you are just donating coz you have0 0% chances to take the current prize pot.
A maximum tickets per participants is necessary to be fair to those cant afford to buy high enough.

Seems like the site owner can just deposit 10 BTC and have a huge chance of winning.
I looked at the site and red flags pop up saying thats what is happening.
If you look only 1 person buys a ton of tickets and wins every time.
But that doesn't mean the site owner is cheating (because the game is provably fair).I looked at the site and red flags pop up saying thats what is happening.

p.s. but it might mean that there is a considerable conflict of interest happening every round...

Nice and innovative lottery project. Congratulations!
It loosely reminds me of a crazy idea (not so +EV) I had long ago:
https://bitcointalksearch.org/topic/idea-ev-positive-expected-value-p2p-raffle-games-peerbet-style-409660
If marketing is well done, your project may become the Google of lotteries!
BTW (talking about Google) why not displaying AdWords like style of ads from sponsors alongside with their banners/images?
Pot decreased considerably...
Tip: raise min ticket purchase to .001 BTC so things get more interesting once more...

Looks like whale wins
Not my lucky day damn but congrats to the winner.
Merry Christmas

Good luck to all!
Good luck to all!
Good luck to everyone by tomorrow ... This will definitely make a nice Christmas gift to whoever wins.

Well on https://www.pevpot.com you can scroll to "past draws" and click on latest: https://www.pevpot.com/draws/6 it's pretty clear who won on that page?
But I agree it should be a bit more highlighted on homepage. Maybe a block under current draw on homepage with "Last draw #6, Prize: 15.66BTC, Winner: 61edb7.. of 10.1009722 BTC, Details". If the draw just ended it should say something like "We are calculating the result, this takes a few hours.. come back later to see if you won!".

Hi,
I am very fan of Ryan and Pevpot. Thanks for this honest, fair website.
Just a remark... for beginners like me, it is IMPOSSIBLE to know if I won, or not.
The only way I know is checking here when you say "the whale won", then I know I did not win.
So, for the last draw, the winner betted 5-10 btc right, then it's not me?
Hope for the next draw you can say how much was betted, then I have a first idea if it's me, or not...
- also this way we'll have the risk-reward ratio
Thanks again, astonished there is not much more players.... no problem then I have more odds to win... less...

Edit: I just noticed that https://www.pevpot.com/draws/6 has off-by-one errors.
The first tx bought 230,000 tickets, 0 through 229,999 - but the linked page says 0 through 230,000 (which is 230,001 tickets). Taking 1 from each number in the 'to' column would fix this.

Just an old habbit of mine to express ranges as [inclusive, exclusive), but it's a bit confusing so i'll change it to [inclusive, inclusive] now
Edit: fixed
Unofficial result for #6: 25238990480fd040ff51f793de5f998d4c3e062f09feaa0f6cf6bab34e44edfc
edit: mm so the "Verify" script says 1,553,035,541 tickets, but the Draw page says 1,553,025,541. This gives 2 different winners (by verify script 5 BTC bettor, by draw page 10 BTC bettor):
>>> print 0x25238990480fd040ff51f793de5f998d4c3e062f09feaa0f6cf6bab34e44edfc % 1553035541

260547462
Which one is correct?
edit: previous draws also seem to add 10k tickets at verify script? So I am guessing the draw page is correct.

edit: previous draws also seem to add 10k tickets at verify script? So I am guessing the draw page is correct.
edit: mm so the "Verify" script says 1,553,035,541 tickets, but the Draw page says 1,553,025,541. This gives 2 different winners (by verify script 5 BTC bettor, by draw page 10 BTC bettor):
>>> print 0x25238990480fd040ff51f793de5f998d4c3e062f09feaa0f6cf6bab34e44edfc % 1553035541

Which one is correct?
