Hi everyone! Introducing simple lottery http://btc-fortune.com

Lottery is very simple!

* Enter your name or nick or whatever and your bitcoin purse to receive a prize
* Press tha Red Button
* Send your bet from 0.1 to 1 BTC to the specified address
* You will get a ticket with a number from 1 to 777 after 1 payment confirmation

You win 160% 180% of a bet: if you get ticket with even number (2,56,100,etc)
You get JackPot: if you get a ticket with number 777

If jackpot is less than 1 BTC, you will play round without jackpot, but still have a 50% chance to win 180% of a bet. Jackpot will be always greater than 1 BTC in any way! When someone will take it, system automatically set Jackpot > 1 BTC (from my funds).

Game is totally interactive, powered by Ajax. You can see incoming bets, tickets and payout history in realtime.

Any questions please send to support@btc-fortune.com or PM me.

And good luck!

----- UPDATE: 30 Aug 2011:

Starting Jackpot amount is now assigned automatically when new round starts, and is growing as much you doing bets.

----- UPDATE: 11 Jan 2012:

Username "JackpotISMine" rolled a 776 on his first try and stopped?

Something looks rigged about that, not sure what! A shill perhaps?!

After having a long run with PRNGs and gambling, I suggest using a TRNG like random.org.

You can snatch random numbers from: http://www.random.org/integers/?num=1&min=1&max=100&col=1&base=10&format=plain

Anyways, seems very similar to betcoin.eu except the chances on yours are worse, also does it payout 160% winners from the jackpot or is there a seperate bank account then only a certain amount gets entered into the jackpot?

Okay, random.org library is on the way. I thought about it. Currently using /dev/urandom source.

also does it payout 160% winners from the jackpot or is there a seperate bank account then only a certain amount gets entered into the jackpot?
Jackpot is an odd number, so it can't win 160%. Jackpot is a Jackpot. You can send any bet (0.1 through 1), and if you take 777, you will be paid with full current jackpot bank. So because "no jackpot" rounds processed when jackpot bank is lower than max bet.

Jackpot has a separate "untochable" account, where ##% of any valid incoming transaction is added each time.

Ivalid bets (out of 0.1-1 range) are paid back without getting tickets.

What i was asking is if you had a separate account for betting bank and jackpot.

Sure.

Bet bank initialized with tens of bitcoins to ensure everyone can win if they win. Even if payout is higher than bet bank, lottery transaction can be processed in hand mode later, when i add some funds to bet bank.

Jackpot has also separate bank.

I see, I also run a similar game and it is probably the most popular of the three, http://berlin.ifixshit.net/index.php?page=commands
!roll is the command for the game.
The only problem I have run into is the occasional extreme win streak destroys the bank

So if I bet 1 and I won, I would get back 1.6?

The house advantage on this is nearly 20% (19.97).  Unless the jackpot is a gigantic multiple of your bet, this game is not worth playing at all.

gigantic multiple of bet can not be reached with chance to take it 1/777. And what was the formula you computed this value?

Look, its just a lottery. For a house advantages you may visit Nevada state with good house advantage cities in it.

I call foul. I just purchased 500+ tickets, and now payouts aren't happening anymore, and my current ticket purchases waiting for confirmation (3 confirmations now) are apparently being dripped into the stream, at a lower than purchased rate of return - 0.16 vs 0.20 that I bought in for.

I am calling shenanigans.

Shenanigans!

Regards,
Jonathan

Oh.. Is it considered spam? Well.. That's inconvenient.

So they aren't confirming even though I paid tx fees?

These are good things to know about Bitcoin. I figured I'd try to break your game just like people broke mine. Lol.

Nope. I see your transactions coming and coming unconfirmed. Is this was a ddos attack? lol Smiley Anyway this was fun. I'll return you all of this when it will end up.

If you try to do this with two different wallets, you will see most transactions unconfirmed during long period of time.

I'm a pretty good authority to try to break stuff. I actually laughed out loud when I saw the web page change and the 200% offer removed.

I was wondering how long it would take for someone to notice Wink
