You should add a history of previous bucket falls on the game webpage, and perhaps estimate of when the next round will decide(assuming all buckets are funded).

I added a round timer!

Everytime I press F5 it just starts from 5:00 again.

Small analysis of the data above:

After 1: 25.04% win vs 24.94% loss: 49.98% win chance
-more data-

How to read? So, you have won the last round, you want to know what the chance of winning after 5 spins is. So in the row: After 5, you see it's 25.4%. Was your last round a loss, then after 5 it will be 24.51%.

(this is done with winning with 50.00 and higher).

What does this show? Nothing, it's random.

Hey vlees, what does the 25% chances relate to? I know you've probably clearly explained it however I'm still a little confused. Shouldn't it be 50% win 50% loss after losing x amount irregardless? I don't see how the 25%'s come in is all.

Also Namworld, I understand your a large investor in Coinroll judging by the trust you gave them (regarding the 200 BTC investment or what not), but I don't think Stunna would appreciate you advertising on his thread. Then again I might be wrong, sorry Stunna if you don't mind ^_^

It means that if you have previously won, the chance for the next roll to be a win is 25.04%. If you have previously lost, the chance for the next roll to be a win is 24.94%. Together this is 49.98% and the other 50.02% are the chance of losing the next round.

Forgot to post the 10k sampleset.
Just as the 2827 one: Client seed is always 0. Serverseed is from 5/24/2013. WIN/LOSS is on numbers higher than 50.50.
So in case anyone thinks he can do some statistical analysis (it's useless, don't bother), you can use this data instead of fetching it yourself and possibly cause lots of bandwidth for the operators.

Got a sample of 10000 bets. Everything goes more towards the 50% so it's safe to say you can't get any useful results out of this at all.

Also some random data which does not say anything at all:
at a distance of 472 spins there is always a win in my data.

Why is this useless? There were other spins inbetween.

649  Economy / Gambling / Re: PrimeDice.com | The New Way to Roll | 1% House | Instant Betting on: May 23, 2013, 01:14:00 PM
take the sha1 hash

You are right, it's SHA1, even though it is to some extent predictable, doing so is still unfeasible to do so in this case.
To read more about why SHA1 is usually bad: http://www.schneier.com/blog/archives/2005/02/sha1_broken.html

Also currently sampling the data for you.

EDIT:
2827 bets, semi-colon separated. For all bets I picked >50.50 as winning parameter and the client seed was set to 0.

First column: WIN/LOSS
Second column: The roll-outcome
Third column: Server seed used for calculation

Average roll number: 50.04464803678808
650  Economy / Gambling / Re: PrimeDice.com | The New Way to Roll | 1% House | Instant Betting on: May 23, 2013, 12:53:17 PM
The outcome is based on the SHA256 from a long string. It is safe to assume that there is no pattern in there. But I can do so in a few mins/hours I guess.
651  Economy / Gambling / Re: PrimeDice.com | The New Way to Roll | 1% House | Instant Betting on: May 23, 2013, 12:31:22 PM
Hmmm, just for statistical analysis I threw the dice 1000 times and this is the outcome (with >50.50 as winning operator):

Won 494 times, lost 506 times. Ok, seems fair with a win-rate of 49.5% but, the average rolled number is 49.31007. After 1000 spins I would've expected this to be closer to 50, but whatever. This analysis took 2 minutes which shows that the server is definitely faster now.

Our current profit is negative 260 Bitcoins,

I'm still wondering how this is possible, with a 1% house edge it seems unlikely you lose so much?!

Edit: AWESOME, site speed is insanely good for me now!

654  Economy / Gambling / Re: BlockRun.com - Penny auctions on the blockchain on: May 22, 2013, 06:23:28 PM
I want to congratulate you on the first auction that made a profit for you guys (the 1 BTC thing).

Seems legit.

It would also allow new people to get a feel for the game before depositing.

You can bet 0 BTC and it will roll for free.

Yes, of course, but it's a lot different using real BTC's then none.

For getting a feeling on how the game works it isn't IMO since the game outcome is not depending on the bet-amount at all.

You deposit money.

You bet on the outcome of a dice that rolls between 0.00 and 100.00 and you get paid out if you give the correct lower bound (so if you say it will be higher than 50.50 and you roll 60, you win the shown multiplier of money (2.00)).

You are done and your balance is over 0.0005? Click checkout and you get your money put in your Wallet.
659  Economy / Gambling / Re: PrimeDice.com | The New Way to Roll | 1% House | Instant Betting | Free BTC on: May 21, 2013, 09:37:40 PM


Grats to new winner! Certainly brings the light the fact that we require 4 confs for 20+ bitcoin transactions. Anyone think this is excessive?

I thought your max payout per bet was 5BTC. Not > 24BTC?!
660  Economy / Gambling / Re: PrimeDice.com | The New Way to Roll | 1% House | Instant Betting | Free BTC on: May 21, 2013, 06:46:35 PM
Also for people that doubt it:

I just put in 0.2BTC, within 10 minutes rose to 0.2135 BTC and clicked checkout.

My transaction had 0 confirmations so nothing happened.

Then my transaction got 1 confirmation and within 10 seconds I got 0.21345 BTC deposited back.

So yes, they pay out, and fast.

Forgot to post "proof" (the transactions):

Sending to them:
http://blockchain.info/tx/1ce585768f0baf7d00c35e74c320df1a0d41b27ec195f52d4176b9003f43c8b9

Receiving it back:
http://blockchain.info/tx/9b6a7b19d1192fabbad6a749a57f2ffea7e756c301d9a6dece135870fe08a857

also @Stunna: I included a 1 second sleep after every roll (that has returned from the server) to prevent causing any more CPU-load than necessary.
