You used one of your other bitcoin addresses, so my system generates a second account for you. Thats no problem, you can have as many accounts as you like. The profit will send to the linked bitcoin address.

Hi tom,

I don't added your address by hand. I checked the database and everything worked as it should. As mentioned before you can not count the entrys in the win/loss or waiting list in order to win.

Sometimes it took some time until the bitcoin server receives the unconfirmed transaction. I don't know why but I think it has to do with the bitcoin networks node connections.

If there are more than one player in the waiting list, the server will deliver the playing order depending on the confirmations.

The latest example was:

Waiting list order:

-> Player 1: Puls....
-> Player 2: Puls...
-> Player 3: Phil...

The server receives the bitcoin transaction block and delivers the following list, depending on confirmation order:

Player 1: Puls....
Player 2: Phil...
Player 3: Puls...

As you see, player 1 bet two times in order to win one. But the confirmation of player 2 was computed faster and so the playing order changed. If you would like to know why the order changed we have to open a thread in the technical discussion area. I am not so deep inside the block-calculation process to answer this question.

I hope that helps.

Kind regards!

@genewitch:
I am open for any ideas. Please be lenient towards me, it's my first bitcoin project and it is the first day running.
But I am very interested in setting up the bets properly.

:-) Damn!

We use the same name for a different idea.

Check out my project: The Bitcoin Lottery

http://k8500.com

Good Idea!

But it must be optimized. What will happen if 10 people win 200% of their bet?
The server account would be empty and the server will not be able to payout the winning values.

What about:

0-50: LOSE
51-69: 5% of Jackpot
70-80: 10% of Jackpot
80-90: 25% of Jackpot
91-99: 50% of Jackpot
100   : JACKPOT!

In that case the winnig profit is bind to the server's account balance.


and btw: Lucker! +1 win to your account 

He's trying to get the jackpot!

And he rolled a 99 in his last round, which was close but no cigar!

Thank you!

Now I count 3 wins with you name, and 2 losses.

But damn, you rolled a 99 in your last loss round.

Close, but no cigar. 

That was the proof of concept.

On my list you were the first player, Louis was the second, xxx the third.

You were on winning position if the confirmations would have been calculated in that order.

But the payment confirmations arrived in that way:

First: Louis (winner)
Second: YOU (lost, sorry)
Third: XXX (winner)

I am sorry for you, but it's good for the game that counting and watching the list will not work everytime.


@tragor: thx for playing!  I will fill up your bitcoin account and send you the needed coins. Whats your bitcoin address?

Greetings,

Der Hamburger

Thank you!

I thought people need another chance to generate some coins. Bitcoin mining with my standard CPU/GPU don't makes me happy ... ;-)

Greetings!

@tragor

haha, it seems you understand the game ;-)

But just to let you know: depending on your location and connections it is possible that the transaction hash (don't know if that is the right word) of the player next to you is computed faster and confirmed earlier.

So watching the win/lose and waiting list will not work always.

Greetings.

Hi Tom,

thx for the spelling corrections, I appreciate that much!

The algo is very easy right now. Every 2nd player has a 100% winning chance. Maybe I should implement a rolling system with 50:50 chance. But only with the current system I can guarantee that there is a winning value.

If I would use a rolling system for regular wins, there will be no value in winning cases. In example if you win two times one after another.

The problem is that I need some more players. At this stage it's easy to guess if you win or lose.

The real competition is to win the jackpot.

I saw you are trying ... so you will understand the system and how it works. You can calculate your risk and decide to play or not. Even if there are more players at the same time you can't calculate it.

... Hmmm, maybe I should implement the rolling system for regular wins and keep some % of the Jackpot to guarantee there will be always a winning value for some regular wins one after another.

I hope you understand what I mean, some english words are missing ...

Greetings!

I am happy to see it works!

@tragor: you have to reload to see your name in the waiting list ... I saw your name. If the transaction is confirmed your name will be displayed in the win or lost area. But there is no waiting list if you win, you name will be displayed instant in the winning area. To see the winning money transaction you have to look into your bitcoin client.

Maybe I should implement a list that shows the outgoing payments (like the waiting list).

Regards,

Der Hamburger

Damn, I hate this waiting for the next block to be processed ...

Thank you!

The current round you will win

Congrats

1. Login:

If you enter your Bitcoin address again, it will check the database and find your name. But maybe a real login system would be better. But I should have explained the login on the website.


2. Low Bet values

My project works really nice on the testnet, but I am a little afraid now on the real network
So I decided to start with low values for testing. If something went wrong, i will pay the winnings by hand.


But I am very happy that the first player gave it a try. Thank you, Ben! Whereever you are!

Regards,

Der Hamburger

READY :-)

Hi!

I have a big problem i can't solve by myself:

I am using PHP and use the API "sendfrom" command to send some transactions.

Is there a way to calculate the exactly needed transaction fee? I tried it with a basic 2% calculation and if I send i.e. 2 BTC I check if my account balance is more than 2 BTC + 2%.

But if I am sending more transactions it results in an error, because the account balance is to low.

Is there a way/command to calculate the correct transactions fee needed for each transaction? Or a way to get the transaction KB value?

Kind regards,

DaMan

thx!

my project works well on testnet. i hope i can release it today for further testing.

Don't panic!

To date I received nothing.

I tried the testnet network, but there are no bitcoins at all. The faucet is closed and I don't see a way to get test-coins. Maybe google knows the answer.

If anyone has a few testnet coins, it would be great if you can send it to my TESTNET address -> msDTYT5nDMoHooP3iV4y9EMXBxqddmGfqq
