The limits are dynamically adjusted based on house funds, so at the time the limit was 50 but now it is 5, at least thats from my understanding.
I think this is dangerous for the house, because the limit dynamically reduces immediately after any large payout.

Therefore, most of the largest bets are going to be ones that the house loses.

The tradeoff ribuck is that there is supposed to be guaranteed funds to payout any win, granted there have been problems with unconfirmed funds being used to payout wins, but they come through eventually.

If there was no dynamic limit and two big payoffs hit in close proximity then SatoshiDICE may be put in the position of having to say "Umm... we will have your money tomorrow" which would kill it's rep.

So all bets eventually get paid ?
My previous 2 that I posted got paid shortly after posting have to really wonder if it the power of the forums ? Smiley I still have a few outstanding though ..

Oh I'm not advocating that they should accept bets that they may not be able to pay off. Just that if they were better capitalized, they could set a limit that is conservative (will probably never need to be dynamically reduced) yet high enough to engage the big players.

Unless I'm missing something in the maths of the dynamic limit, it's going to harm the business if the way it works isn't changed.

I think you're missing something in the maths.

The house edge is the same whatever the bet size, so the bet size doesn't hurt the expected house win rate, it just affects the risk of ruin.  And the risk of ruin is managed by dynamically adjusting the maximum bet size to only accept bets they can afford to lose.

If they only accept bets up to 100 when they can afford to (which makes sense) they still make 1.5% (or whatever the edge is these days - it's advertised differently in different places) on average each time they take a bet for 100 BTC.

By the way, here's where I saw it say the house edge is less than 1%:

I've had some issues lately with transactions taking a long time to confirm and not showing in my wallet till they got confirmed, but I could still look them up on the website to see if I won or not.

But now I've encountered another issue: I've made a bet and it doesn't show up on the website, even though it does show up on blockchain.info and it's already confirmed:
blockchain transaction
link to satoshidice for that transaction

SD is going VERY slowly today, there's been quite a few bets that took a couple hours to actually get processed, but so far they all do eventually get processed.

It got processed now. Yay Smiley

Was just weird that that one took so long to show up on the website, while I never had any problems with that before.

I wonder if they're waiting to have enough confirmed funds to pay winners now to avoid the other problem that's been going on of paying out with funds that never confirm.

I wonder the reason behind the business decision to limit bets to 5 BTC, even those in the under 32,000, under 64,000 range.

That certainly limits the automated martingale bots.

On the surface I would presume this is to lower their risk to variance and let their wallet grow bigger so that they can offer larger maximums on the higher payoff bets, particularly those at the "less than 256" and lower range.

Other reasons might exist too though.  There's been nearly three-quarter million dollars worth of bitcoins wagered through SatoshiDICE since it began.  There aren't many online gambling services where you can go down to 7-11, give the cashier $500, and before you've even left the store pissed it away by making a losing bet online.  So maybe this low limit is a way to prevent the service from being used in this manner.  

Gaming machines were invented by engineers (well, first by a car mechanic, then innovation from engineers).  But these machines didn't immediately become wild successes until they were improved upon by psychologists.

Here's an article describing dopamine and gambling:
 - http://www.zimbio.com/Parkinson's+disease/articles/PvPlIdIItCp/How+come+Slot+machine+game+Gambling+Considered

5 BTC maximums are more likely to ensure its players keep coming back.  Thus SatoshiDICE is doing something it needs to do especially considering it only has a period of time before it is likely to face competitors taking the exact same approach.

I thought 5BTC meas SatoshiDICE has been robbed (cheated,defeated)...

ok, i'm confused. the site's working fine - that's not the confusion.

i see the payout odds for < 4800 are a bit over 73%, with payout of 1.343%. unless i'm a bigger idiot then i think i am, that means over multiple bets, you're garunteed to win 23% more oftne then you lose, meaning it's effectivley a garunteed way to increase your supply of income.

obviously, i'm missing something here. little help?

You're not doubling your money every time you win, you are getting 1.343x your money. So the expected value is
Code:
((732422*1.343)+(267578*0.005))/1000000=0.984980636

Plus, you pay transaction fees both ways.

would you mind trotting that past me again? where'd ya get the 26758*0.005?

i'f i'm understandign the math there correctly, you're saying that over time, you'd lose a small amount. about 2.5%, is that right?

Expected value is the sum of each possible return to you, multiplied by the probability of it happening.

There are 2 possible outcomes:
  * you win 1.343 times your money, with probability 0.732422
  * you win 0.005 times your money, with probability 1 - 0.732422 = 0.267578
(because even when you lose you get a little something back - just to prove they got and processed your bet).

So the expected return is (0.732422 * 1.343) + (0.267578 * 0.005) = 0.984980636 times your money.

That means you lose (1 - 0.984980636) * 100 = 1.5019364% on average per bet.

Say you play this game 1 million (1,000,000) times, and bet 1 BTC each time. On average, you will win 732,422 times out of 1,000,000 plays, because the probability of winning is 73.2422%. If you win you will get 1.343 x 1 BTC, or 1.343 BTC. So by playing 1,000,000 times you are expected to win (732422*1.343) Bitcoins.

Given that if you make a bet you either win or lose the bet, it is expected that you win 73.2422% of the time, and you make 1,000,000 bets, then it is expected that you lose (1000000-732422), or 267,578, times. If you lose a bet, SatoshiDice pays you back 0.005x your bet, so if you bet 1 BTC each time for 1,000,000 plays, you will get (267578*0.005) BTC back.

This means that in 1,000,000 bets, and thus betting 1,000,000 BTC, you will get (732422*1.343)+(267578*0.005) back. ((732422*1.343)+(267578*0.005)), the amount you get back, over the amount you originally bet, 1,000,000 BTC:
Code:
((732422*1.343)+(267578*0.005))/1000000

Equals 0.984980636. Therefore, for every 1 BTC you bet, you are expected to get 0.984980636 BTC back on average (so you lose ~1.5%). This is the expected value. I hope this clears up the confusion.
