I've been asked to 'audit' this game by its owner.  He's given me 0.5 BTC and asked me to place 5 bets of roughly 0.1 BTC each over 2 days, and to verify that the game is indeed provably fair.

I'll be betting 0.08 + 0.09 + 0.10 + 0.11 + 0.12 = 0.50 BTC.  3 bets today, and 2 tomorrow.

The relevant public keys are:

27/03/2013:0426d052be7bb661b70efa4b11096e3642eddbb5d14e61c5b911b3934538653f30d44a93a32d8a2 85941420038c02a6ddb38d26fc2216e5732a5fa3f8bbf13ded3

In the interest of not polluting the blockchain too much, I'll be sending my bets to 1GRWQA3wLGL9i5aW371Nd1HnF4QaBNEGxG which disables the 1 satishi payout when you lose.  Not that I'll be losing any of course, but better safe than sorry...

[dooglus]

I'll be betting 0.08 + 0.09 + 0.10 + 0.11 + 0.12 = 0.50 BTC.  3 bets today, and 2 tomorrow.

0.08 BTC: #190 30d33b08fedc8d4f5f987838509a0a1efae33b21b2f16bda50d9785d0d371855
0.09 BTC: #192 69e62c58b3f6a9810c67c40c44ceef2e21d6c5a5d56d470b1179b63674eaa5e3

Probably best not to ask what happened with #191; it's a little embarrassing...

My bets are currently hovering one row up from the bottom - presumably awaiting confirmation before I get to see if I won or not:



Edit: but the title of this thread says it's a "zero conf" game.  And one of my bets is confirmed now anyway but I still don't see if I won or not.  The site could use a 'FAQ' page which talks about how many confirmations are required.

Edit2: my 3 bets now all have at least 12 confirmations, but they're still 'pending' on the site.  I wanted to check the result for myself, since the daily secret is now revealed, but the description is a little unclear:

Then the 1st 2 bytes are used. If the bit is 1 the ball goes left if it is 0 it goes right.

The first 2 bytes have 16 bits in total, but there are only 14 decisions to make so it would be better to be explicit about which bits are used and in which order.  The Python script does so, but maybe say it in English too.

I used bitaddress to check that the published secret does correspond to the previously published public key:



Turns out all 3 of my bets lost (I modified the Python script to take command line arguments, and to tell me the payout):

This provably sucks!  

[dooglus]

I sent my 4th and 5th bets:

0.11 BTC: #231 89004a2f7ea6d91b63479f63a498cfdb423b15050b3eb4642a569c1d7ca43c8a

Again the bets are hovering one step from the bottom, even though bet #230 went straight to its final position.  What does its status of 'initial' mean?  This should be explained in the FAQ.  Also, my bets show up with 'return amount: 0'.  Does that mean they lost?



Edit: both these bets seem to have won:



the payments appeared in my wallet too:



Now I have to wait until some time tomorrow (what time does the secret get revealed?  In what timezone?  More FAQ fodder...) to confirm that I should have won, and that the site isn't cheating itself.

While I find it hard to tell the icons apart, the two bet transactions each have 2 confirmations, and the two payout transactions each have a single confirmation.

Mine is pending too, I think I lost as well.

All 14 are shown in my pending bets, but I'm guessing that's because the daily secret for those bets has been revealed.

[Jenger]

Hm.. my bet isn't even showing. should be #235 for .009 btc

I thought it would appear after confirming, but it didnt.

[nibor]

I am almost too embarrassed to show my face!

Just after I sent dooglus an email asking him to test, the hard disk failed on the machine it was running on!

I recovered onto another server, but there were numerous issues.
1) The backup was obviously a day old so was a bit of fun ensuring we did not "double pay" anyone.
2) There was a bug in the recovery code when we would return zero if you lose so those were stuck in pending.
3) It has been running on a bit of a duff machine all day and seems to have stopped processing at some point.

But we are now back on the original machine and working on moving to more resilient one.
Anyway returning the bets that lost and did not come through as expected:

    sys.exit(1)

# This is the Private Key from the Bet Details page.
# This is only displayed the day AFTER you place the bet.
private=sys.argv[1]

#This is the hash of the betting transaction (Tx Hash on Bet Details page).
txhash= sys.argv[2]

digest=hashlib.new('ripemd160',hashlib.sha256(private+":"+txhash).digest()).digest()
path=""

pos = 14
for i in range(0,7):
    if (ord(digest[0]) & (1<<i)) ==(1<<i):

    else:

print "For Private Key  : "+private

print "payout is        : %sx" % (payouts[pos/2],)

[Stunna]

hahaha, very neat game. The animation/graphics could definitely use improvement though but nonetheless pretty interesting

[nibor]

Just to be open, we have changed our payout policy. We still payout 99%, but if you win we subtract the 0.0005BTC transaction fee from the payment. This is the same policy as SatoshiDice.

Sorry for this, but currently bets under 0.05 cost us money due to the low margin we operate on. This change will mean that we only lose on bets under 0.025. We do not want to prevent small bets, as we know this allows people to try the site and gain confidence that we are honest.

Those tests didn't work very well due to the site having hardware problems just as I was placing my bets.

I'm going to try again.

This time I'll be making 5 bets again, as follows: 0.098 + 0.099 + 0.100 + 0.101 + 0.102 BTC = 0.5 BTC.  3 today 2 tomorrow, as before.

The secret for those 2 bets was revealed.  It's e982e81737fe7c0eb576b1775d632d133a10e6615b698a70cf89f1b20178509d.

bitaddress.org tells me the "Public Key (130 characters [0-9A-F])" for that private key is:

049B27A6245C19C10C067FB1271F1DF747FC36036EA2142375E11A935C2652F0E61640E9FCDC46D 59413C49AE76817A0960CA40F68269502BC8CF7BB0FB30F5A21

So checking with the Python script:

chris@chris:~$ ~/Downloads/path.py e982e81737fe7c0eb576b1775d632d133a10e6615b698a70cf89f1b20178509d b9eda6488ff37856c932269c00ea0f3917e30062d800ea9192e37dca08991423

We have now reduced the fees (0.0001) for smaller bets (<0.1).
This will allow you to try us out without incurring large (0.0005) fees on small winnings.

Obviously this will mean your winning bets will take a bit longer to confirm.

Also please use the second address to avoid us cluttering the blockchain with tiny payments when you lose.
