hey, server is down again, its obviously too weak for bitcoind..
I've ordered a new, powerful dedicated server, I'll set it up tomorrow.

I don't like gambling games.
I thought it would be more like minefield on windows.
Where you can puzzle out where the mines are.
I'd love to see skill-based games with the money inside the gameplay.
Like command&conquer with bitcoins.
each unit you buy/kill is real money and it's player vs player money. The "house" doesn't earn much but it will be more successful then yet another gambling game.
I agree with you on that one, I'd like to see skill based games too, I'll have time to work on something like this really soon.. not sure about success, but I'd like to see such a thing. site is up btw, sorry, I was not around and something exploded and automated checks failed to restart the service.. its running now. |

hey, about minefield entry, (I'm the admin)
few corrections:
- there is no minimum cashout or cashin
- minimum bet is 0.001
and slow cashouts? they are done instantaneously when you press the button, with a standard bitcoin client, and server (not the user) pays a standard fee so that transactions are as fast as the bitcoin network allows it.

This is my favourite gambling website, so cool!  thank you:) btw, I've lowered the minimum bet.. people seem to be interested in that. I'll pby lose bitcoin in the long run on transaction fees but, nvm. |

switched to sha256 as requested, partially applied the new designs

If you want to, we could work together and I could make you some new tiles..
yup, pmed |

What is the bitcoinadress? Both adresses top left and bottom dont work for me.
Click on the Balance button (top) for deposits and withdrawals. Thanks. It works. So now ... If I come from 'bitvisitor' I don't want to play in a frame. So i need a link to go to ' http://minefield.bitcoinlab.org' I have found the link only here in this forum. I see ... It's not a fair play. This is a delusion a fake, i mean not fair. You take 100% of the stake. But you pay only 0, 02 to 0, xx profit. And you dont say it. Example: I play 3 mines at stake is 0.01 btc. I win 5 times 1.02 per cent. Ok you mean: 2% x 0,01. For me 5 x 0.0002 btc= 0.001 First the profits are 0.001 btc. So i had to win 50 times to win 100%. Now I lose. And you take 0.01 btc = 100%! Where do you write this naughty game rules?I have need 0,03 btc to understand your trick, because i don't believe this. yes, it's not a 'fair' play in the sense that the amount you'll receive is slightly lower (~10% in this case) then chances of you winning. but this is a fact for all gambling. if you played with 24 mines, you would have to win only 0.045 times to double your bitcoin. if you play lottery, you have to win only 0.0000001 (whatever) times to double your money, that doesn't make lottery or 24 mines scenario any more fair. you have to take your chances of winning into account. I'll take some time to explain it to you a bit later. maybe. |

ok, site is back up, it took more then 24 hours to resync with the blockchain, bitcoind went crazy due to too many addresses being generated, needed to recreate the wallet.
|
|
|
|
It came online for a few minutes. Now 503 again.
It's OK with me as long as the site works when I play for real.
I know, working on it. |
|
|
|
OK.
By the way, do you use your own server or do you use a VPS?
its a cheap VPS, its too weak for bitcoind which is extremely resource intensive lately. when I start working on new stuff I'll revise the infrastructure. which will include renting a dedicated machine and isolating services |
|

The site is 503 again.
I got my BTC ready to bet.
Thank you for your service to the bitcoin community.
I know, it will stay offline for a few hours, bitcoind went crazy and is downloading a whole blockchain now. I'm sorry you've hit 503 twice, the uptime is usually pretty good. btw, you've had some good suggestions for the site, let me know if there is a service you'd like to see in the future, I will be working on new things soon and am slightly out of the loop with services that are available atm. I will do a websocket multiplayer game for sure. |

You changed from SHA256 to MD5.
Your Trust string looks like this:
md5("[[1,0,0,0,1],[0,1,0,1,1],[1,0,1,1,0],[0,1,0,0,0],[0,0,1,0,0]] 6194c0e2ffb667fa41385e16d9fb010b")
Due to weaknesses in MD5, it is entirely possible to fudge the array (on the left) and quickly compliment the arbitrary string (on the right) to generate a colliding MD5.
If you are going to continue using MD5, I recommend replacing the long arbitrary string with a sequence of 3 common dictionary words that maintains a strong entropy but makes colliding MD5 values nay impossible.
I would recommend just using a different hashing function. Since the left side is of known structure, just differences between 1s and 0s, one could easily start a game with 24 mines, giving only 25 possible forms for the left side. Then, it's just a three word dictionary attack... if you pull from too small of a pool of words then coming up with a rainbow table becomes relatively easy. Someone could setup a bot to run you dry, irreversibly in a matter of minutes after the rainbow table was created. Go with a different hash function. The first line of the quote states that you went from SHA 256 to MD5. Why? I think you forget the 128 bits of the last part "6194c0e2ffb667fa41385e16d9fb010b" In the post that I quoted, it points out that due to weakness in MD5 you can find a valid string for that and still come up with a valid MD5 for an arbitrary left portion. Their solution was to use dictionary words, but I was pointing out that a rainbow table renders that approach susceptible to cheating. The random 128 bits is secure but doesn't prove that the site isn't cheating (I trust that it isn't, but it still doesn't prove it); the dictionary approach does not guarantee that the user won't cheat. The easiest solution is to just use a stronger hashing algorithm. Then any arbitrary string is sufficient to demonstrate that the site isn't cheating, since SHA 256 has (as far as I know) never produced a hash collision. let me just acknowledge this. you people are totally right. I will take time in the near future to switch back to SHA256, I won't risk it with dictionary words and such, as just using a proper hashing function is easy. I did use SHA256 before. but after a system upgrade the library I was using broke, and I quickly just switched to MD5 to get it to work and left it at that. the site will be back on SHA256 within the week. btw, site is currently down, bitcoind went crazy, I'm repolling the block chain. |

Suggestions:
Stats feature (total won, total lost, etc.)
Backup your URL to a flash drive directly from the site.
Let the user select a field size.

I hope this helped.
yup, those are all good suggestions, thank you. I will probably start working on a few new services in a few months. I think I won't work on new features for this one much. |

Thanks for fixing it.
That was so fast! And this is a cool game.
thanks, and good luck!  |

I played on it before, but on free-play mode.
Can't wait to play for real.
ooops sorry, gimme a few mins ok, fixed |

Are you still running the site at all? I made a deposit and it just switched to a 403 error.
403? are you using the proxy or something? you should never get 403s from my service. yeah, its running and should be fine, lemme know if you are still having trouble. |

So...what ended up happening with that whole 'Android app' thing? I was kind of looking forward to it.
I don't think that's happening unfortunately. the guy working on it almost finished it and gave up That's a shame. I wish I could take over for him, but I know nothing about programming! Haha  . just recently I was too 'hey, that android thing, whatsup with that?' so I messaged him |
