wow you did, are you sure? that's really unlucky, I just ran a simulation, out of 10M rounds, it happened once....

Whew!

Glad to hear, I've been waiting quite a while now to find out if I won my last wager or not! Hoping I get my other wins back soon too...

Lost (11) 48000 bets in a row and finally won 2 at like 20BTC or so! ...been so long now I can't remember LOL

How much longer are you thinking? The site (and payouts) have been down for a couple of hours now Shocked

Sorry, I think I did win 1 small bet in between somewhere - I did lose like 11 out of 12 bets at 48000 though, then finally won a few after all that. Almost couldn't believe it and almost everytime it was just barely over 48000 Sad

Can't really complain though - it was the exact opposite yesterday, I couldn't lose! Just trying to get back to where I was and chasing my bets (damn Martingale... LOL)

Just curious, the past few days I have gotten (and seen) my bets within seconds, maybe a min or two tops - since last night it is taking more like 30-60 min between bets now. My last bet was sent 54 minutes ago and has 6 confirmations already...

Is this just because the site is so busy? Or will this speed up again in the future? It's agonizing waiting in the mean time (especially with larger 10-20BTC bets)!!

Anyways, I love the site! I'm hooked! Just wish it were a bit faster is all Wink

Processing is coming back up now. It will take a little bet to catch up but it is running through the transactions now.

Do you have an estimate on how long that will take?

The rebuild I just completed failed, so I'm guessing probably another hour. Sorry.

Seems it's down ?

Yeah, I am rebuilding the wallet to try to include some transactions that got missed somehow.

I think the less than 24000's max bet is wrong, it's more than the less than 32000's max bet:

lessthan 16000   1dice7fUkz5h4z2wPc1wLMPWgB5mDwKDx    24.4141%   4.063x   0.818%   99.182%   0.0010   55.8718
lessthan 24000   1dice7W2AicHosf5EL3GFDUVga7TgtPFn    36.6211%   2.708x   0.818%   99.182%   0.0010   100.1605
lessthan 32000   1dice8EMZmqKvrGE4Qc9bUFf9PX3xaYDp    48.8281%   2.031x   0.818%   99.182%   0.0010   99.5534

The max is based on the the prize multiplier and some modeling related to the win percentage. Due to this, the numbers are not linear like you would expect.

In short, the max bet on 24000 might be higher because the system calculates it is safe to do so because people are less likely to win it and run the house out of money.

Here is an easier double spend attack:

5. Bet transaction that won't confirm: Intentionally construct a bet transaction that miners won't include in blocks due to fee rules. Then after you see whether you won or lost, you have plenty of time to mine your own block that includes either the bet and payout transactions or a double spend of the bet transaction. Of course not all miners follow identical rules so you may not have an arbitrarily long amount of time to mine the block, but it makes the attack much more feasible and profitable than if you had to mine the very next block.

I like it, 99.182% return is 0.818% stupid tax, the best that I've heard of so far, gave it a try & lost 1 + 1+ 1+ 2 + 3 = 8 BTC on the <24000 36.62% game, oh well maybe I'll be lucky in love then instead Wink

One more possible attack:

4. Duplicate transactions: It is possible for the same transaction hash to occur more than once (see BIP 30 for details). Since the result of a bet depends only on the day's secret and the bet transaction hash, it is possible to place a bet and if it wins, repeat the same bet again within the same day. For example, prepare some transactions as follows: Mine a block with address A, then send the coins to B, then to C. Mine another block with address A and send the coins to B. Mine another block with address A and leave the coins there. Now you can send coins from C to SatoshiDice and if the bet is a win, place two more bets B->C->SatoshiDice and A->B->C->SatoshiDice. The site could prevent this attack easily though (perhaps even unintentionally, if it uses transaction hashes as keys in a database to determine whether a payout has been sent).
