why there are bets of 100 btc if the max is 25 btc ?

why there are bets of 100 btc if the max is 25 btc ?

Because you can put more than one bet in a single transaction, but all of them get the same 'lucky number'.  So you can bet:

* 25 BTC on lessthan 32000,
* 25 BTC on lessthan 32768,
* 25 BTC on lessthan 24000, and
* 25 BTC on lessthan 16000

in a single transaction, get lucky number 63500, and lose the whole lot at once.

I guess technically it's 4 bets, but since you only get one lucky number per transaction I was counting it as one.

whats happens if someone send more than the max. bet ?

It is returned to you.

Here's an example of a 140 BTC bet that was refunded.

Usually the refunded amount is the same as the bet, but sometimes it's slightly more or slightly less.  I don't know why the refund isn't always the same as the bet amount.

Edit: according to my calculations, 1789 bets have been refunded.  934 of them refunded the right amount.  308 refunded slightly more than the bet amount, and 547 refunded slightly less.  The biggest overpayment was 0.00018160 BTC and the biggest underpayment was 0.00014976 BTC, so really insignificant amounts.

I think those amounts that are close are actually wins on less than 64000.

For example this one is a small win, but with the transaction fee taken out it ends up as a loss:

Oh, of course.  I should have looked at those transactions in more detail.

Thanks for addressing my post.

Darn it, would have paid >5600BTC if I hit 0...

The URL http://satoshidice.com (with no www) is down, although there are many links to it all over the forum (including the first post).

Seems OK from here.  Maybe they fixed it.

I was just looking at the odds on the main page:



It looks to me like the stated house edge is incorrect.

For example, on the 'under 32768' bet, if the house edge is 3% then you should get 1.94x when you win, but the main page says you only get 1.935x.  That represents a house edge of 3.25%:

>>> under = 32768
>>> he = 3.0
>>> 65536 * (1 - he/100) / under
1.94
>>> 100 * (1 - (1.935 * under / 65536))
3.25

Similarly for the 'under 1000' bet, for a house edge of 3% you should get 63.57x but you only get 63.247x, for a house edge of 3.49%:

>>> under = 1000
>>> 65536 * (1 - he/100) / under
63.57
>>> 100 * (1 - (63.247 * under / 65536))
3.49273681640625

The same happens for every bet I've looked at so far.  The quoted reward for winning is less than the stated house edge would call for.

Is there something wrong with my maths here?  Or what's up?  Is SatoshiDice really taking a house edge of more than they claim?

[dooglus]

It looks to me like the stated house edge is incorrect.

I figured out what's going on.  The house edge is 3.5% on winning bets, and -0.5% on losing bets, making 3.0% overall.

[dooglus]

They are not any of ours.  My guess is they are created by someone for interacting with satoshidice.  The "BTC" seems a little silly.  I mean, it is a bitcoin address, that it is for bitcoins seems a little redundant.

It looks like that was someone testing a clone of SatoshiDice.

Bastards. It's on.

[nimda]

free market and all that but I bet they charge more in fees

[evoorhees]

SatoshiDice house edge is now reduced down to 1.9%  (was 3% for a while to help us heal some of our abysmal losses in June).  Please go easy on us this time

Play now!

Enjoy!

I have a situation,

I accidentally withdrew some funds directly from my mtgox account to a satoshi dice game, funnily the bet won and the funds were sent from satoshi to the originating address. I have been in touch with MTGOX and they claim that the address that my withdrawal request was paid from was not one from mtgox's wallet. I find it hard to understand how that is possible. And so now they claim the coins that were returned is not in their possession. Is that possible ? What are your views guys ?

It's possible the coins they sent you were 'change' from a previous withdrawal they made to someone else, and so they don't see the address in their wallet.  That doesn't mean they don't control the address however.

And so now they claim the coins that were returned is not in their possession. Is that possible ? What are your views guys ?

The coins they sent on your behalf probably either came from a change address or somebody else's deposit address.  In the first case they should still have your coins, but in the second case they will have been seen as a deposit by this other mtgox account holder, and may well have already been withdrawn by him.

I don't see how mtgox can claim that they don't control the address from which they made your withdrawal however.  That sounds impossible to me.

Thats what I think too, here are the details the original satoshi dice transaction

The address in question is 1CFVvAgicGheKxa3PedMgmw78LT5YXrk7a the coins were sent from mtgox when I did my withdrawal request.

I think everything can be seen from those links, now I dont know how MTGOX is claiming to not have that address in their wallet. Is there anything else I can do ?

I don't see why Gox would do this but you could conceivably have a third party handle your hot wallet and in that case the coins would go to the hot wallet handler. As annoying as it is it doesn't seem like Gox' responsibility to sort that sort of thing out. Ohh, I just saw it was 17 coins, good luck.

So seriously if MtGox don't return the 17 BTC, they should get a scammer tag like Bulanula has coz they've done the same thing as him - accepted coins by accident but not returned them.

Makes sense. And the lulz potential... oh, the lulz...
