Topic: [Announce] BTC Riches - Win 7x your bet - MD5 Verification (Read 3174 times)
Yeah I was thinking you could just use bitcoin itself.
I want to play but why do we need to use that service?
You have to deposit somehow, why not with bitcoin balance? It goes into exactly the same database.
Edit: Is it because you need to create a username/password? I will see what I need to do to make this optional so that people can play without making an account.

Okay, found it.
It seems FF doesn't send the value of an image input, whereas Chrome does:
$_POST['open'] is 1 in Chrome and NULL in Firefox.
Fixed it now by using another hidden var.
Are you the owner of bitcoinbalance.com?? I need to ask you something.It seems FF doesn't send the value of an image input, whereas Chrome does:
Code:
$_POST['open'] is 1 in Chrome and NULL in Firefox.
Fixed it now by using another hidden var.
Yep, how can I help?
Thanks for the interest... I haven't completed the code yet to allow 3rd-party sites as that will be a bit more complex, security-wise.
The reason I'm able to connect my sites easily at present is because they all directly hook in to the same database and are hosted on the same server.
What other options are you considering for registration/payments? (using mybitcoin or running bitcoind yourself?)

I'm not able to bet. I deposited 1BTC to 1FUYFiPw9zDJZ3iiawrPfehmmBtfSJMNYD, it shows up in my balance, but I put .1 in the box, put in my guess, and click Open and it just refreshes the page. Never attempts to open the safe, and never shows an outcome.
Edit: I just put in to withdrawal my 1BTC back out until the bugs are ironed out.
Edit: I just put in to withdrawal my 1BTC back out until the bugs are ironed out.
I just tried exactly that and it worked. Can you tell me what browser you're using, and what time you attempted it?
Thank you.
I tried with both Firefox 5.0 and ie9
Time was a minute or two before my last post.
Thanks, I can confirm it's not working in FF5 for me either, only Chrome for some reason.

If I'm doing my math right.... according to http://en.wikipedia.org/wiki/House_advantage#House_advantage it's 12.5% house advantage. Seems to be a little high.
Oh, I think I might be able to see how this worked...
Are you outputting something along the lines of md5sum("Left-Left-Right")?
If so, it's a simple dictionary attack... the gambler computes the 15 possible different MD5sums in advance and then compares them to what displays.
It's not just left-left-right, but it also had a whole heap of random characters after that, and then hashes that total string.Are you outputting something along the lines of md5sum("Left-Left-Right")?

This was the first thing I looked into.

(Accidentally edited away my previous answer to this)

Also, there are only 8 possible combos, not 15.
Hmm, there was an error causing it to use the same combo on certain occasions after a win.
Thanks Dan, I've sent you1 btc 3 btc, that was very helpful.
Edit: Okay it's all fixed and back online, btcriches.com and bitcoinbalance.com.
Jeez that was an expensive coding error on my part.
Glad the site wasn't exactly 'hacked' though.
I just paid a heavy typo-tax.

I'm a retard, I forgot to switch to random.org after testing:
But that still doesn't explain to me how they could know rand() was going to return three 1's in a row.
I might be being dumb here (I'm not logged on and don't have anything deposited,) but the MD5 on the page doesn't change when you refresh the page. That suggests that the same combination is coming up every time.Code:
//get a random number for next game:
/*$ch = curl_init('http://www.random.org/integers/?num=1&min=1&max=8&col=1&base=10&format=plain&rnd=new');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
$randnum = trim(curl_exec($ch));*/
$randnum=rand(1,8); //temp
But that still doesn't explain to me how they could know rand() was going to return three 1's in a row.
That's only if you don't play... as soon as you play a game, it changes.
(Well, it's supposed to... that's something worth checking - thanks)
