ADDED THE 1/100 AND THE 1/1000, WIN UP TO 1 BTC:
Following the system as the 1/10, i have added the 1/100 and the 1/1000. Players can now win up to 1 Bitcoin !
As usual, any feedback would be appreciated. I will pay 1 ticket in the 1/10 to anyone giving me constructive feedback on the system, not the design.
I am going to focus again on polishing the design now.

The 1/10 IS NOW INSTANT DRAW:
Once a ticket is paid for and confirmed once, The house gets the transaction ID.
Then, we wait for the next bitcoin block to be found by the network.
If the last number of the hash of the next block matches the last number of your transaction ID, you WIN !

---

PROVABILITY : The system has been changed. It is now based on the next block hash to pick the winner. We need testers to try that system , read the last post to know how to participate.

---

DESIGN : I have changed the design, i hope it looks better than the first one, gimme some feedback !

PROVABILITY : The 1/10 is now 100 % provable and fair. Here is how it goes  : As soon as the 10th ticket is sold, the system gets the Transaction ID of that last ticket bought, and use the last integer of the TXID to pick the Ticket Number. It is displayed on the 1/10 page so everyone can verify it. Again, some feedback would be appreciated.

CONTENT : I have added the "Stats" page. The presentation is dull and plain, it is still a work in progress. As soon as i am fixed on what exactly i want to be in the page, i'll design it properly. Here again, if you think something is needed in that page, feel free to say it.

I am going to leave it like that for a little bit, see if i can get people to try it. But after multiple test, all systems seem to be working as intended. Good luck to those who try !

Hello everyone !

I am launching today : http://www.bit-lottery.com
It is a lottery based on the ticket purchased, instead of the time, here is the description :

The draws are based on how many tickets are bought.
As an example : You buy a ticket for the 1/10 draw, and as soon as 10 tickets are bought on the system, the server picks a winner randomly
Same goes for the 1/50 or 1/100 draws : A winner is picked by the system as soon as 50 tickets have been bought.

You win the amount of tickets bought minus 1 ticket. So for the 1/10 draw, you will win the amount of 9 tickets : 0.009 bitcoins.
The amount is directly transferred to the bitcoin address you entered when you bought your ticket.

No. The server picks a random winner, based on the ticket ID. As soon as we have 10 tickets in the system, we pick a random number between 1 and 10, and pick the corresponding ticket ID.
We are currently working on a way to provide complete transparency on the random pick. We have multiple solutions, and are looking which one would work best without breaking the system.

There is no automatic solution for that yet, but yes you can : Enter your BTC address each and everytime. Do not send multiple time the same amount to the same address, we must have your entry registered in the database first, which happens when you click on the "checkout".

As long as necessary. We want to make sure we have complete transparency, in a system that works without any issues at all. We will open the 1/50 and 1/100 draws once we get out of beta.

UPDATE : I am looking for 10 different people ( or at least 10 different addresses ) to try the system, and give me some feedback. Also please comment and critics are welcome, i am looking at improving the site and whatever i may have missed. if you agree to test it, please post your btc address in this thread, so that we all know it is actually working. i will send the money back to the first 10 addresses who try the system.

Nice project andi hope this transparancy

Btc address: 1Ff6QmudtWwH6mDGnvGGCrKmkz2JwAW28N

Alright, as soon as i see your TXID in the ticket list, i ll send back the amount of the ticket. Thanks guys !

its free right or i must send btc for test ur site?

No the system is not free. You have to send the payment for your ticket : 0.001 to the address that you got when you clicked on payout.
It becomes free when i send you back the 0.001 btc ... i will do that for the first 10 tickets.

EDIT : I did not build an entire system / website to scam 10 people for 0.001 btc. I simply would really like to prove that the system is working properly before i launch any ad campaigns.

ups sorry i think free for try ur system, if this free i want try :)

Nobody else ???

EDIT :  Actually, i did input your BTC address myself and purchased the ticket for rogerdonkey.

Purchased tickets for :

Need 6 more addresses / users please, come on guys, free win of 0.009 BTC , all i need is your BTC Address.

I sent one bet to your game,

I got 1 confirmation already.

ok, I'll give it a shot. Here is my btc addr 1ArieqQVJJMBPS7V3ZKtvfpoAyjU2cmfVZ

please let me know whether I'am in the first 10 people list or not.

Alright, sorry, you went in the previous draw, where i was trying to gather people on IRC too to try it. We did make a test though. I sent you back your ticket price.

I just paid for your ticket, you are in the next draw 1-10.
http://www.bit-lottery.com/1-10.php

I am paying for another round guys. Get in, get a ticket, i will pay for it. i wanna make another test !

address:

14NuZ3Q3DWsZWgVoQTMFdjUvy7nAywUtwj

Count me in, my address is 1BG2D8pnZDAyKa8dpxYnphR9S68wVgoYtv

Wish me luck guys.

So I am just curious who was the winner in the last draw and how to redeem the prize

I could help you making this automated, although it seems that you want this to be manual payouts? Its not very hard with automatic payouts.

This system to work correctly need some kind of probability fair because right now just someone got the prize but we can't verify that the op hasn't give the amount to an alt account. Maybe some blockchain algorithm or something.

Hmmmm , alright guys. i think i haven t been clear enough. sorry.

Basically, i need people to enter their bitcoin address here : http://www.bit-lottery.com/1-10.php   , and click checkout.
Once you do that, you get in the database. I will see that and pay for your tickets, you won t have to send the payment.



The system is completly automatic. you can see the winner on the same page http://www.bit-lottery.com/1-10.php ( last draw ). The winner is the one that has a Transaction ID. Although i agree that the design of the website does not make that clear enough, i will make it with more clarity.


Absolutly. I am trying to think of the proper way to make that completly transparent and prove 100 % that the winner is picked randomly. I posted a topic there :
https://bitcointalk.org/index.php?topic=760498.0
With a bounty of 0.1 btc for anyone who can come up with the right idea as to how to do it.

Also website could use a little spiffing up. Its very plain and dark, look up bootstrap, and bootswatch.com it will really help. Good luck on your project, theres no really defined bitcoin lottery, like there is with dice and blackjack (777coin.com and primedice.com).

Thank you. Yea i got some bad feedback for the design. I am about to change that, as soon as i am done testing with the second test draw.

Alright, 4 tickets in, need 6 more : It's free, give it a roll guys, might win 0.009 BTC !

Sent 0.001. Its returned if I don't win right? Hope I won!

I think i just returned it to you. I said it is a test and i pay for the tickets. A man is as good as his word.

5 More tickets / testers guys ! C'Mooonnnnnn ! ;-)

I have submitted my btc address, we need 5 more people to get it started. I will promote this thread to my local community to get more people signed up

i just send mine   ;)
https://blockchain.info/address/12yK2cfRUcqnsmiZNaNhdqJfymC8eZ29cR
4 more left !
Success  !!

Count me  :)
Sent 0.001 btc from my address 1EeottMHyQSBkDNeZr2ZnKUtg58Xv199XD

Thanks  :D

Alright people, Thanks everyone for the support, really appreciate it.
Now, it seems during the night, we got more than needed. I am about to pay for them all, but some will be put in the draw after this one by the system.

And we have winner ! The overflow have been put in the next draw.

I think my 2 test are done. Everything worked as i wanted. I am going to focus on the design now, got a lot of negative feedbacks about it, and will come back here to ask for new feedbacks, with probably another round or two for free. Feel free to play in the meantime ! :-)

I actually have questions for you people.

Which one would you be more likely to play between :

1/10 draw , ticket price at 0.001 , win 0.01 BTC
1/50 draw , ticket price at 0.001 , win 0.05 BTC
1/100 draw , ticket price at 0.001 , win 0.1 BTC
Daily draw , ticket price at 0.01 , win The pot of the day ( the sum of all tickets bought )
hourly draw, ticket price at 0.01 , win the pot of the hour ( sum of all ticket bought ).

Or may be something else ???  ( knowing i have no budget, i can t put a price to win from my wallet unfortunatly, so the winnings must always be the sum of tickets previously bought )

I like that idea. The only problem is, while your small you have to start out with a small amount of pools. More pools with diversify the bet and there will be less demand for each one, making slower gamse and smaller pools. Those 5 should be the max until you see some more popularity.

I get your point and i agree. but my question was actually what would you prefer, which one would you be more likely to play basically ? Especially since, again your point, i dont want to "overload and slow the system" , i prefer to focus on just a game or two that people really wanna play, at least for the first few weeks.

Quick update : i made some changes to the design.. added last winner thingy.. trying to make it ..."shinnier". I will do left and middle this week end probably.

Since i needed to add a table to keep a "winners list", i made a quick round for free, just paid for 8 tickets, to make sure the system was working properly. Congratz to the latest winner ! https://blockchain.info/tx/3d0a552f71ab96a3564453e03fac7c7130ef02300abd765d9d5bf21ea6b432dd

My deposit address is: 1kvx8HsCK31AvDxDfev2BGbHxQcY32aLG

OK people you all want free btc, that's all good... but hey it works both ways... i really would like to know which is the draw that you would be more likely to play...

I like 1/10 draw more than others as it only requires 10 participants at most

Thank you !!!

Since you are all the only one who took the time to answer, you ll get a ticket for free. Post your btc address !

Although, i have made my mind. Got some feedback that some would prefer bigger winning amount, understandable. So i chose to go with the 1/10, a daily draw and a weekly draw.
Still working on the design, but almost done !

After that, comes the choice to make it completely transparent, so that everyone can see for sure that it was random. Working few solutions, i ll post them here, see what people would prefer.

No offense, but why should people play your lottery game instead of a 10% dice bet?
Benefits of dice game over your game:
1. Can get the result instantly
2. Provably fair
3. lower edge (ie. higher win multiplier)

IMO, you should implement a provably fair mechanism and lower the edge to compete with dice games. :)

Your question would be the same as saying : why would anyone play a money game at all ? When you could just not play at all, and don't take any risk.
Also, would would anyone play any lottery at all ?
I simply like the idea, i am interested in the learning process as to how to develop it.

Now for the provably fair mechanism : i said it multiple times and even opened another thread to collect ideas as to how to do that. It is in the work, and IT WILL BE PROVABLY FAIR. That is what the beta is for, i need some feedback and decide exactly what / how it will be. If you wish to play it, by all means, go play the dice, i am not here to force people to play. 

DESIGN : I have changed the design, i hope it looks better than the first one, gimme some feedback !

PROVABILITY : The 1/10 is now 100 % provable and fair. Here is how it goes  : As soon as the 10th ticket is sold, the system gets the Transaction ID of that last ticket bought, and use the last integer of the TXID to pick the Ticket Number. It is displayed on the 1/10 page so everyone can verify it. Again, some feedback would be appreciated.

CONTENT : I have added the "Stats" page. The presentation is dull and plain, it is still a work in progress. As soon as i am fixed on what exactly i want to be in the page, i'll design it properly. Here again, if you think something is needed in that page, feel free to say it.

I am going to leave it like that for a little bit, see if i can get people to try it. But after multiple test, all systems seem to be working as intended. Good luck to those who try !

Yes provably fair but its a bad idea. When making your own transactions, you can see the txid before it is broadcasted, and you can cancel if you want, so basically you could try 10 times and then broadcast it when you get your right number.

I see... Alright i am going to change that and will base the draw on the next block hash instead.

I think this is a bad idea as well, because its still predictable I think, maybe calculate it from the block after the next one, hashed with the address of the final payer, and take the hex value of the first couple digits of the hash.

ALRIGHT !!

I just finished tweaking the system, it is now based on the next block hash. I made a quick test and it seems to be working properly.

Although : I NEED 10 TESTERS PLEASE.

I WILL PAY FOR YOUR TICKET !

How to proceed :
Go there : http://www.bit-lottery.com/1-10.php
Enter your bitcoin address, click checkout.
It will return you a bitcoin address to send the payment to.
Post that bitcoin address here, and i will make the payment myself.

In other words, you have a 1/10 chance to win 0.09 BTC for free...

PS :  I will check the database to make sure the bitcoin address you are posting is registered... so don't try it to give me another address...
PS2 : I will do that for the first 10 addresses posted only.


THANKS AND GOOD LUCK !

Thanks everyone for your participation !

I will now continue on, starting by polishing a few things... Then i'll start working on the daily and weekly draws.
Hopefully the site will get some regulars for the 1/10 in the meantime... Maybe i could start a signature campaign for it... but i am not sure how that works.

Any feedback would be appreciated though !

Thanks!!! I am so happy I won  ;D

Glad for you you !

Hey people : I have no idea what the price of the ticket for the 1/10 should be ...

Knowing the amount to win is 9 Times the price of a ticket... For what ticket price would you be ready to play ???

0.001 btc a ticket, win 0.009 ?
0.01 btc a ticket, win 0.09 ?
0.1 ??

Especially looking at gamblers here, please help me set that price once and for all !

I'd be willing to wager 0.01 (~$4) for a 1/10 chance to win 0.09 (~$40)... I'd probably do it once a week or so.

Haven't tried it yet, but I realy like the fairness and transparancy of the game. Good job!

I like it as well. Bigger lotteries with time limit instead of /10 would be sweet as well

Hey Guys, Thanks for your feedback ! it is encouraging  !

Now, i made an update that i think everybody is going to like.

The 1/10 Draw is now INSTANT.
Basically, the system does not wait for 10 tickets to be in. Instead, it checks with the TXID and the Block hash.

As an example :
You buy your ticket, send your payment: the system gets the transaction ID.
As soon as it gets confirmed once, your ticket gets in the queue.
Now, the system waits for the next block to be found. As soon as that happens, It takes the last number of the TXID, and the last number of the block hash.
If they matches : Your ticket wins, payment is sent.

That basically gives the same odds : 1/10 chances to win. But it is now "almost instant" . The wait time is between your txid gets confirmed once, and the next block to be found.
That also gives a 2 blocks advance.

I am going to display the last 10 tickets draw on the same page : http://www.bit-lottery.com/1-10.php

Now... i would like to test the payment... I am pretty sure it is working as it is the same as before... But i'd prefer to be 150 % it is working properly... But i keep losing !! I guess i'll just keep trying until i win, haha .

Again , any feedback would be appreciated !

PS: If that works well and i see that people starts playing. I will make a 1/100 chance to win, but 100 times the amount to win. I am not btc rich unfortunatly, so i have to wait for the system to get some BTC rolling in. Hopefully i won't have 10 winners in a row that will dry up the wallet :-)

ADDED THE 1/100 AND THE 1/1000, WIN UP TO 1 BTC:
Following the system as the 1/10, i have added the 1/100 and the 1/1000. Players can now win up to 1 Bitcoin !
As usual, any feedback would be appreciated. I will pay 1 ticket in the 1/10 to anyone giving me constructive feedback on the system, not the design.
I am going to focus again on polishing the design now.

I bet this would be popular if you added support for microwallet and made another lottery for smaller/larger prizes.

For example 1,000 could pay .0001 to win .099 which is an achievable amount to make from faucets and/or paid to click sites.

Alternatively 100 could enter for 0.0001 to win 0.099 or something

Since support for microwallet within the bitcoin gambling scene is pretty much nonexistent you'd control the market.

Alright, i'll bite !

But, i admit i am ignorant when it comes to "microwallet" concept ? Could you give me an example of what it would be ? How would it be different from a " normal " wallet ?
Also, the issue i have right now with smaller prices are the TX fees ... Why would anyone get a ticket for less than the TXfee itself ?
Nevertheless, you are right when you say " this WOULD be popular" : to be honest, i was expecting that more people try it... I am starting to feel like i should not even bother launching any ad campaign...Truth is, i am not sure what to do with that thing. May be i should start to look into an signature campaign, but even that... not sure thing of anything right now...
