Just-Dice.com : Invest in 1% House Edge Dice Game

[qxzn]

I still have a hard time understanding it. I see that random values have no past. Its random. But random doesnt look random anymore the more values you have. So even when you throw a perfect dice 10,000 times and you get these results:
1-2000
2-2000
3-3000
4-2000
5-2000
6-1000

Yeah the more values you add, the 3's and 6's are going to tend to come into line. However, that's not because 6's are somehow more likely, or 3's any less. It's just because as you add more values, the discrepancies become relatively smaller.

Try this: what happens if you add 5000 to all the results? E.g. the fair die is just doing it's job being perfectly fair now. Your new totals are:

1-7000
2-7000
3-8000
4-7000
5-7000
6-6000

Now the 3s and 6s are still 1000 away from where they should be, but as a percentage they're only about 15% out of line instead of 50%. It is only in this sense that things eventually "come into line".

Do a simulation for a million rolls. Or even better, do a million real rolls. It's a nice distribution. One of my accounts has 1.3 million rolls.

This is the post I was about to make.  Thanks for saving me the time.

To further push the point home, imagine you've done 6 million more rolls, and the totals are:

1-1002000
2-1002000
3-1003000
4-1002000
5-1002000
6-1001000

then all 6 numbers are very close to the expected 16.666%.  All of them have become closer to where they "should" be, even though the 6's didn't have to do anything special to "catch up".

dooglus,

it's every day more difficult to connect to jd for me.

I have to reload page 5-10 times before it starts updating.

Right now I've been banned for an hour...

[wolverine.ks]

thoughts on having the investors balances list signed with dooglus's PGP key as well as give investors the option to sign their weekly balances?

If you're using firefox, that hangs all the time.  I get hangs all the time, but then chrome works perfectly.  I wish there would be a message on the site recommending that you don't use firefox.  Wonder how many gamblers get scared off.

[wolverine.ks]

or just fix the Firefox bug?

Can somebody verify those to be fair?  I must have rolled over 30 times @ 10% and won nothing.  and then the last two bets which are pasted above @ 90% were both losers. 
I hope someone finds a way to destroy JD

I can't verify the fairness, but you're only a bit unlucky. 30 losses in a row (or more) at 10% will happen about 5% of the time, and 2 losses in a row (or more) at 90% will happen about 1% of the time. A bit unlucky, but not extremely so. Sorry about your losses.

You need to generate a new server seed so that the website will display the previous one used for these rolls. Hit the Randomize button on the site, then open these bet-links again.

I would like the ability to increase my allocated risk when investing, Instead of .5% the option upto 5% would be beneficial for myself.

Is this something that could be implemented?

While a good feature, you should read about expected return when you wager > 100% Kelly.

Yes this is a good point, I myself would be willing to top up my investment on just dice.

Maybe if it was implemented as an advanced feature with a warning.

other than trusting that it says "lose", how can i double check these

You can check it using the hash of server seed, server seed, client seed and nonce.
Here is a verifier: click.

Why do you even gamble somewhere when you don't understand the provably fair mechanism?

This verifier uses the old roll-generation algorithm. Dooglus changed it a while ago.

I just updated the one you linked with the new implementation detailed in the "Fair?" tab of JD: http://jsfiddle.net/KWAnw/1/

It correctly verifies the rolls VolcanicEruptor posted.
