I don't understand why you pay that small amount even when losing. What is the motivation?

You can't use a transaction twice ... without a lot of effort and only if done very soon after the original transaction.

lol, was going to play for a little bit and lost 7 times in a row as soon as i started.

 That's all for today

So this is for protecting against double-spend attacks? How does it help?

Imagine you send a bet and get nothing back.  Did you lose, or did your bet get lost or stuck somewhere?  You can't tell.

So they send a small amount back when you lose to let you know that the bet was processed successfully, and that you lost.

That way you're not left wondering whether their server is just being slow.

I just read what http://www.satoshidice.com/bits.php has to say about it:

If you lose, the return your bet times 0.005

which looks like a typo to me - perhaps it should say 'they return your bet'?  Either way, the losing payment is half of 1 percent of your bet.

[evoorhees]

No - it's not a free bump - it's you trying to steal his customers and using his popularity without paying for it and then making up excuses for it.

... hopefully you lose business for doing this, not gain from it ...

No, it is just us letting people know these games are currently available. We hope to see SatoshiDice.com expand their select soon

Please let people know about your games without spamming other games' threads. It's in bad taste.

I won't be posting on your thread that SatoshiDice's new website is about to launch... for example.

Speaking of comments made in bad taste

yawn

Man... if you're going to rip off my site, at least make a better looking one. Yours is an uglier version with a chat window and no ability to bet over 1btc   

We did take your feed back on board and revamped most of our site, All games support bitcoin links for easy betting and we borrowed your idea of having a blockchain.info link for each address. The chat window and log window will be the last to get a face lift

We will not spam our games to your clients in your thread when players are asking for our games whose description  matches ours, but will will comment to say we do have those games.

We look forward to seeing your new site launch

Well - sort of But not really ...

It means that the transaction process is complete - once the payment has been made, there will be no other transactions coming off your bet.

dooglus I guess worded it differently but better - you actually know the status of your bet - even when you lose.

But it goes one step further, the status can't change either.

Ahh, that makes sense. Thanks for clearing it up!

Can you develop an alternative game where the I can win what I actually rolled? for example, I rolled a 18, but my bet was on lessthan 64000, so I missed out on a potentially big payout. In this alternative game, if I roll a 16, then I get paid the 1998.853x multiplier or whatever multiplier that would be mathematically correct. I'd like to play this style.

If they paid 64000x for every zero, 31981.573x for every 1, etc. using the current payouts, the expected return per 1 BTC bet would be 9.3 BTC.

So to make a game with a small positive (1.9%) expectation for the house, but with the same proportions of the payouts, we need to scale the current multipliers back by 9.3 / 0.981.  I left the 'losing' return at 0.005, and slightly adjusted the 3rd decimal place of the payouts to make it work.  Then we get:

Code:

lessthan 1	6750.942x
lessthan 2	3373.527x
lessthan 4	1686.764x
lessthan 8	 843.382x
lessthan 16	 421.691x
lessthan 32	 210.846x
lessthan 64	 105.423x
lessthan 128	  52.712x
lessthan 256	  26.356x
lessthan 512	  13.178x
lessthan 1000	   6.747x
lessthan 1500	   4.498x
lessthan 2000	   3.374x
lessthan 3000	   2.249x
lessthan 4000	   1.687x
lessthan 6000	   1.125x
lessthan 8000	   0.844x
lessthan 12000	   0.563x
lessthan 16000	   0.422x
lessthan 24000	   0.282x
lessthan 32000	   0.211x
lessthan 32768	   0.206x
lessthan 48000	   0.141x
lessthan 52000	   0.130x
lessthan 56000	   0.121x
lessthan 60000	   0.113x
lessthan 64000	   0.106x
64000 or more	   0.005x

Which gives pretty much the correct house edge:

Code:

>>> (
     1 * 6750.942 +
     1 * 3373.527 +
     2 * 1686.764 +
     4 *  843.382 +
     8 *  421.691 +
    16 *  210.846 +
    32 *  105.423 +
    64 *   52.712 +
   128 *   26.356 +
   256 *   13.178 +
   488 *    6.747 +
   500 *    4.498 +
   500 *    3.374 +
  1000 *    2.249 +
  1000 *    1.687 +
  2000 *    1.125 +
  2000 *    0.844 +
  4000 *    0.563 +
  4000 *    0.422 +

  8000 *    0.211 +

  1536 *    0.005) / 65536

Would people be willing to play a game where you need to roll less than 6000 to 'win'?  It means that less than one ticket in ten is a winning ticket.

That sounds like a really cool game and I don't see a crypto problem or any large barriers to implementation.

Great news, the new SatoshiDICE site is now ready for some testing!!

http://src.satoshidice.com/rev2/

There is now live-feed data coming through. I'd be very grateful to anyone who checks out this new design and provides feedback (either technical issues or suggestions or any kind of comments).

After some feedback and after we've watched performance, we'll put this on the normal SatoshiDice.com domain.

Cheers!

[sgravina]

New site is pretty.

I still won't play.  Not until I get the 100 bitcoins I lost back.  And that is going to have to be by magic.  No more dice for me.

Even if I crack SHA256 and start mining all the bitcoins I still won't bet them on SatoshiDICE.

[dooglus]

I'd be very grateful to anyone who checks out this new design and provides feedback (either technical issues or suggestions or any kind of comments).

I sent you a PM with a bunch of comments a couple of weeks ago and received no response.  Not sure if you got it.

There's an issue with the live display of big losses:

* the amounts displayed are obviously too big
* the text doesn't fit in the box

Ah thanks Dooglus!

Yes I did receive that message and many of those suggestions will be included. I really appreciate the feedback

Yeah, a game needs to be made that more closely mimics a scratch off lotto ticket.  Multiple different prize levels to win with on transaction, and every transaction has a chance at a jackpot prize level.

Voila: BTCMultiplier.com.  The jackpot is a good idea...

[Lurk]

hey i just placed a couple bets...they both showed up as a win with a pop up on my bottom task bar.  when i looked at my transactions one of the wins disappeared? so it only paid me out for 1 win instead of 2.

 [edit]

  wen i look up the payment transaction is says does not exist.    cbf22b626b12fdff8768be7287fd37a2c7f6830a482de3b62511fe85d8460d5e

[edit]  ok so it happened again  payment hash:

 Think im done until this gets figured out.....please take a look eevorhees

I'll look into why that second payment isn't being picked up by the network.  You will absolutely get it, it just might take some time.

thanks... ive never had this happen before.  the only trouble ive ever ran into was when i used the blockchain wallet and spent unconfirmed funds.
  the new site looks great by the way!  and thanks for looking into it.
