Thank you Mr. dooglus. That is really an informative analysis. It tells the gamblers out there that if you want to do a martinegale on 50% (lessthan 32768), you better have a bankroll good for 26 consecutive losses (as a maximum). Although you could always beat the record. The maximum bet means you'll be forced to bet the maximum more than once just to recoup losses if you reach this far.

I'm just curious about another statistic. What's the next longest streak (2nd longest, 3rd longest, 4th longest)? And how often did they occur, if more than once?

The list of longest sequences of wins and losses I posted yesterday had a mistake.  I wasn't counting any sequences which didn't finish yet.  Like the sequence of losing "lessthan 2" bets, which has been building since the start of the game.

Here's a correct list, as of now-ish:

Quote
lessthan     1     99531 bets       1 wins (222877-119  to 222877-119 )   85965 losses (176831-34   to 222877-118 )
lessthan     2      4762 bets       0 wins (None        to None       )    4762 losses (177355-25   to 226257-136 )
lessthan     4      7320 bets       1 wins (213426-111  to 213426-111 )    4259 losses (177365-68   to 213425-123 )

lessthan 24000    248014 bets      14 wins (213616-75   to 213616-1053)      24 losses (225928-411  to 225937-147 )
lessthan 32000   1127422 bets      34 wins (184344-956  to 184345-16  )      65 losses (184391-665  to 184391-739 )
lessthan 32768    611382 bets      30 wins (180866-367  to 180868-167 )      26 losses (216081-852  to 216081-901 )
lessthan 48000    343930 bets      68 wins (182535-247  to 182536-268 )      17 losses (189347-98   to 189347-126 )
lessthan 52000     74960 bets      59 wins (202481-127  to 202567-150 )       9 losses (213719-227  to 213720-86  )
lessthan 56000     63223 bets      60 wins (224067-454  to 224072-192 )       5 losses (196994-197  to 197000-76  )
lessthan 60000     98374 bets     146 wins (213472-454  to 213513-36  )       4 losses (210367-580  to 210367-590 )
lessthan 64000     15488 bets     439 wins (180744-103  to 181691-101 )       2 losses (177069-43   to 177087-37  )

Note there are only 4762 "lessthan 2" losses shown, whereas the most recent daily stats showed there were 4821 losses on the same bet.  That's because I'm not counting two bets in the same transaction before Jan 3rd as being two bets when counting sequence length (since they always got the same lucky number), but am counting them as 2 bets in the daily stats.

It seems the transaction format of SD changed. I do not see the usual dust.

They don't charge the 0.0005 BTC fee to losing payouts any more (as of about a week, I think) so the smallest payout now is 0.5% of the 0.01 BTC min bet, or 5000 satoshis.

They had a planned downtime recently.
Ok I thought it was the downtime due to the fork alert.

The downtime caused a flat-spot like I was expected when processing was down for the recent blockchain fork:

Can you explain why it's only appearing now ?

How crazy unlikely (or lucky?) is this? 0.000000000000000012219410750632388 %? Ain't it more likely to win "lessthan 1" two times in a row?

I think it's about as unlikely as winning "lessthan 1" 3.9 times in a row:

Quote
>>> math.log((1 / (1-32000/65536.0)**65), 65536)
3.9267190562541083

I'm trying to think of an explanation for this.  There's no way it happened by pure chance, it's just too unlikely.

The miner of that block could have deliberately picked losing bets to mine.  If the results of the bets were published without any confirmations, like they used to always be some time ago, then that's possible.  I don't see why a miner would do that though.

It's possible that SatoshiDice's hot wallet was out of confirmed coins to pay out winners at the time, and so was only settling losing bets, but that shouldn't affect which bet transactions got mined.

So I'm at a loss to explain it.

How about the conspiracy theory answer: someone who knew the daily secret deliberately sent a bunch of losing bets to manipulate the stats.  But why would a SatoshiDice insider have any incentive to make it look like lots of small bets were losing?

I just noticed "65 losses (184391-665  to 184391-739" on the "lessthan 32000" game.  That's a huge number of losses in a row.  They're all in the same block, too.

I checked, and there really were 65 losing "lessthan 32000" bets in a row in this block: http://blockexplorer.com/b/184391.  Search for 25088, which is the winning bet before the losing streak starts, then pair up the txids in the first column with the bettx column in this (large, and so not inlined) collection of screenshots: https://i.imgur.com/GhH7b2H.png

This is how much they have left.

Any questions?

Updated the stats.

I DO think there is another whale out there with at least 10k distributed across other addresses.  That guy uses a similar betting pattern to the first whale but much smaller bet sizes.

$ awk '{print $3, $1}' allbets.txt | grep '^32000 ' | uniq -c | sort -n | tail
$ awk '{print $3, $1}' allbets.txt | grep '^32768 ' | uniq -c | sort -n | tail
$ awk '{print $3, $1}' allbets.txt | grep '^48000 ' | uniq -c | sort -n | tail
$ awk '{print $3, $1}' allbets.txt | grep '^52000 ' | uniq -c | sort -n | tail
$ awk '{print $3, $1}' allbets.txt | grep '^56000 ' | uniq -c | sort -n | tail
$ awk '{print $3, $1}' allbets.txt | grep '^60000 ' | uniq -c | sort -n | tail
$ awk '{print $3, $1}' allbets.txt | grep '^64000 ' | uniq -c | sort -n | tail

awk: cannot open allbets.txt (No such file or directory)

I'm regenerating the list such that I can sort it into the order that the bets were placed rather than payout order.  That should give better numbers I think.  It will take a few hours though.

Edit: the list of bets I'm generating has the block number and transaction number within the block, so I can sort it once it's done.  I just checked a few early entries to make sure the bets were being listed right, and it showed me:

Quote
32000 5020 L 178122-8 0.04
24000 5019 L 178122-8 0.04
12000 5018 L 178122-8 0.04

ie. the 8th transaction (counting from 0) in block 178122 contains 3 bets of 0.04 BTC.  I checked this against blockchain.info (http://blockchain.info/block-index/215305/0000000000000583451e3795919b1afbc6c6b96a0da71773015999a70da6aeb7) but found that these 3 bets were in the 9th transaction, and that there were bets in the 3rd transaction which show up in my list as being the 37th transaction.  So I was worried my code is listing the transactions in the wrong order.

It turns out though that my code lists the transactions in the same order as blockexplorer (http://blockexplorer.com/block/0000000000000583451e3795919b1afbc6c6b96a0da71773015999a70da6aeb7) so it's blockchain.info that's listing the transactions in an apparently random order.

It's only got as far as last October so far, but already found sequences of 30 and 26 wins in a row at lessthan 32768, and 23 losses in a row too:

     23 L
     26 W
     30 W

Edit2: It's up to December 28th now, and I've improved the code that finds the longest sequences so it tells you which block and transaction number each sequence starts and ends at:

That looks like a genuine run of 30 wins on lessthan 32768.  Isn't that incredibly unlikely?  Like a 1-in-a-billion chance?

Edit3: I see a problem.  It used to be that all the bets in a single transaction would get the same lucky number.  It's also possible to bet on the same address multiple times in a single transaction.  That means you can win the same bet twice in a single transaction, and I'm counting that as 2 in a row.  See the 'lessthan 256' above - it says "2 wins (208181-71   to 208181-71)".  That's because he bet on lessthan 256 twice in the same transaction, and both bets got the same lucky number:
  http://blockchain.info/tx-index/33164014/9
  http://blockchain.info/tx-index/33164014/19
or see lines 3 and 8 here.

OK, so it's finished making the list, and I've changed the script to ignore multiple bets in a single transaction in blocks earlier than block 213879 (when the rule changed).  Here's a list of the current losest winning and losing streaks per bet:

Quote

lessthan 16000       9 wins (184483-183  to 184483-294 )      42 losses (219440-228  to 219440-350 )
lessthan 24000      14 wins (213616-75   to 213616-1053)      22 losses (201314-281  to 201319-67  )
lessthan 32000      34 wins (184344-956  to 184345-16  )      65 losses (184391-665  to 184391-739 )
lessthan 32768      30 wins (180866-367  to 180868-167 )      26 losses (216081-852  to 216081-901 )

So the 30 wins in a row on lessthan 32768 was real.  Even more incredible is the run of 34 wins on the slightly harder lessthan 32000 game.

Edit76: I just noticed "65 losses (184391-665  to 184391-739" on the "lessthan 32000" game.  That's a huge number of losses in a row.  They're all in the same block, too.

Here's the list of them:

I started producing a list of all the bets to find the longest winning and losing chains and found a problem:

SatoshiDice has at times in the past run low on confirmed funds in their hot wallet.  When this happens, they can easily pay out losing bets (since all they need to do that is the incoming bet itself), but they have to wait before they can pay out winning bets.  This results in large groups of consecutive bets with the same result.

I've only looked through a fraction of the bets and already found a chain of 319 losing "lessthan 32000" bets in a row, and also a chain of 287 winning "lessthan 32000" bets in a row.

This makes me think it's not worth continuing with this analysis, since it doesn't tell us anything other than that SatoshiDice sometimes bunches winning bets together.

Here's the progress so far.  In less than 400k bets I see all these chains:
