CURRENT ROUND: Temporarely down for new features
Winner of Week 1: 1N5okqtBZ9PUNipwJunqKUkcdS1GZpsrWx winning 0.133 btc by being closest to the winning number of 67 with his number of 74.9491

How to win big when current pool is 0?

It is a lottery so the pool will build as people send more.
As a bonus for the first round the pool is starting with 0.1 btc as the prize. I will be loading 0.1 btc in a couple minutes

Will there be a bonus for the first ticket buyers? I am interested in playing this week
EDIT:
Owner will be starting the lottery pool with 0.1 btc, I guess that counts as a bonus. I just need to wait for some btc to confirm then I will purchase a ticket. Good luck to all other ticket purchasers

I have made the deposit of 0.1 btc as a round bonus. https://blockchain.info/tx/adf8a1bda5fa4e1d46fdc0591be17aa8c8042b4d630d76716c30cd7a7ffa459b
If a trusted escrow agrees to set up an address (I will not have the private key) we will move all tickets over and continue from his address. This weeks address is currently in play and the lotto has started 1 day early (official start date is 2/25/2015)
Good luck!
Remember, the current pool is 0.1 btc so you could turn your 0.01 and multiply it by 10x if you win!

Sent my ticket, https://blockchain.info/tx/577ca9916316494aba02f0f3faa7299f3b321d8db7be5183e828e382618e8af3
I will update this post when it is listed on their website

Good luck Mr. funtotry, our system is automated so it will be inserted roughly a minute after your TX is confirmed. Prize pool is now 0.11 btc

It will be fun to see where this goes.

how the price one ticket?
can we enter more than one ticket?

One ticket costs 0.01 btc and currently you have to send each ticket separately. You want this to get a different random number per ticket and be listed on the page multiple times. If you would like to increase prize pool without buying more tickets just send more than 0.01 btc and it will automatically add to the prize pool.

Can you tell us when the Round 1 will end?

Weekly round reset is too vague and long. Exact end time will be good. Can you make it 48 hours or something?

Can I be an escrow?
Want to start out. :D

site looks clean and cool congrats admin for great design,
how many tickets will be in round 1 ?

hard to gain interest from a newbie acct.

Address has been updated on the site, and the balance and tickets have been moved over in this tx https://blockchain.info/tx/5ae58de953b97342232b78ddce9dfb11176b6cb462c414de454967a43041ea32
Keep in mind that the original week's address will be in the hash released at the end of the week because we cannot change it.

My bet has been added to the new address I see it in the table. I hope I win! No one else entered yet so there is high change of that!

Lets see if op will payout

Funds are escrowed by Blazr (https://bitcointalk.org/index.php?topic=967026.msg10573887#msg10573887), so he has no choice.

I am just putting out the hashes here (they have been on the site for the entire round)
SHA256 of the random number: 6c6fdd4b0ea375c6d1da76cb6372301d5f9587b9d5e76b6a718c2f3260f9a8db
SHA256 of the secret key: 2aa203b0bc2154c2390e6927e49ba72628f81b89c9e83eeaee3fb3ac72a39f87
Read my provably fair page and see how these are verifiable.

Quoting this so you cannot change it later. Don't want my bet being cheated!

I want to know when the round 1 will end.

Please put a countdown or something in your site.


How is the NUMBER CHOSEN selected?

Please read the provably fair part of the site (bitlotto.co/fair.php (http://bitlotto.co/fair.php)).
The random number is randomly chosen from random.org, and it is not provably fair, because it does not matter, we choose it at the beginning and there is no way to "choose" your lotto number.
Exactly 1 week from the round start (25th)

How does probably fair work if you don't mind me asking?

Its actually called provably fair and if you took the time to read the url that you just quoted then maybe you could figure it out as I took the time to outline this.
One more ticket has been purchased, for a total of a 0.14 prize pool!!!!!!!!!!!!!!!!!!!!!1111ONEONEONE

No need to get angry man. I was wonder what makes it provably fair?

Bump, 3-4 days left until the lottery ends. Bet 0.01 and have a chance of winning 0.15 btc!

Lottery has officially ended! I will be taking a break for march break while developing some new features, but of course if enough people are interested I could get it up for this week.
Here you can verify this message
This week's random number has been chosen to be 67 and the round started on 2/25/2015 with the lotto address of 1Lot1mSfkciv6akWNyoAx5MfHahjHn22ai. Random string is cow64
Should be hashed to 6c6fdd4b0ea375c6d1da76cb6372301d5f9587b9d5e76b6a718c2f3260f9a8db with sha256
Which has been quoted multiple times and has been on the website for the entire week.
This means this person with the txid: https://blockchain.info/tx/577ca9916316494aba02f0f3faa7299f3b321d8db7be5183e828e382618e8af3
Has won with the random number of 74.9491 (closest to 67) and address of 1N5okqtBZ9PUNipwJunqKUkcdS1GZpsrWx
So the winnings of 0.14 * 0.95 = 0.133 btc are sent to the winning address 1N5okqtBZ9PUNipwJunqKUkcdS1GZpsrWx
Other 5% has been donated to the escrow.
Keep in mind that I hashed the string before I switched the system to escrow, so the old address 1Lot1mSfkciv6akWNyoAx5MfHahjHn22ai has been in the hash, but the most important thing is that you can verify the number 67 hasn't changed since the beginning of the week.
How to verify your bet:
Secret key for this week was Z2mFaU1JRoP7qvHzYi3L0xkE4sgBtWe5
The has of it has been also quoted and on the site for the rest of the week 2aa203b0bc2154c2390e6927e49ba72628f81b89c9e83eeaee3fb3ac72a39f87

ok so this thing is legit after all.

Hey it looks like my ticket purchase https://blockchain.info/tx/577ca9916316494aba02f0f3faa7299f3b321d8db7be5183e828e382618e8af3
has just won!
YAAAYYYY
I will update when I get my payout of 0.133 as you promised.
I just turned 0.01 into 0.133, pretty good payout for me  ;D ;D ;D ;D ;D ;D

Payment to winner has been sent. Note that there was a small glitch on the website and the pool was displayed as being 0.01BTC extra. The actual pool was 0.1299 BTC, which means the winner got 0.123405BTC.

https://blockchain.info/tx/76d9f6f92f0c8b4ee477ab324aca131248822bf99836c6f9af33976cccfb2a29

Thank you I have received my payment. Im looking forward to next round, maybe we can get a much bigger prize please let us know when the next round is coming up.

Cool good to know that this thing worked out the pool will probably be bigger next week because more people will trust the site.

Any time frame on when there is going to be a round 2?

I do not understand the way the game, the winner chosen at random?  ???

It supposedly is just like in normal lotter - so yes, it should be total random pick.

He mentioned before that it is provably fair so it generates a random number in a way that can be shown to prove the owner cannot select a person to make win.

He needs to make all the process more transparent to see the list of participants and the way the winner is chosen .

He could release a spread sheet showing all of the math behind it at the end of each week to make the site more trust worthy.
