Topic: probiwon.com: New gambling shooting game with 94.2% return (Read 10265 times)
Hey, I am in a luck strike! Thanks for this great game! It is really fair at a near 100% return. ^^
Probiwon thinks my Bitcoin address is invalid, and I'm not sure why. I'm unable to play the games now, and I previously could.
Yeah, I tried it today (first time) and was unable to play due to an "Invalid address" message.
When you played last?

I've seen this error message on other services when the underlying Bitcoin daemon stops responding to RPC calls.
bitcoind is ok

The hashing can be done in javascript, and the nonce can be generated randomly by default or accept mashing keys into a text field if the user wants.

Need a scheme that will work in user's browser.
That's all well and good, but how do we know the secret was randomly and fairly generated?
In theory, it should be possible to generate a provably random number. I don't know whether PIW's customers care enough for it to be worthwhile to implement. The protocol would go like this:
PIW generates a secret.
Secret: 0cd645b8cc7325838b2fa809f308e28ef9463494
PIW sends hash of secret to user.
Hashed-Secret: d18b235bd2c80890a8aee4c564cfbce251633bb3
User records hashed secret.
User generates a nonce.
Nonce: ce61948f0d95be1746017cc327b8d28316055c8f
Secret and Nonce are concatenated and hashed to form the final random result.
Concatenation: 0cd645b8cc7325838b2fa809f308e28ef9463494ce61948f0d95be1746017cc327b8d28316055c8 f

I did just notice something strange,
I have played quite a few times,
One of my payments to Acceptor address:14XFTVDQrBhw79jYScyiZBx6bp17XHQq6f - for 10 BTC has not been confirmed after over 3 hours.
Yet other payments have been ok (but not to this address I just doublechecked) - I am even up by a few BTC, but I thought I would let you know in case there is a bug.
Is that address one of your Acceptor addresses? I am sure I cut and pasted it from your site while I was playing.

The payment has now been accepted and the game played. (I won - yeehaaa!)
It was not a problem with the Probiwon site - it was a network delay.
Thanks.

10 BTC payment to this address is unconfirmed
A quick question. Could you show some pseudocode of how you handle the bets? Does the acceptor plays any role in the odds?
After creation of a new addresses pair (your address + acceptor address) site generates random secret, shows sha256(secret) to you and waits for your bet. After bet is accepted and game played new random secret generated immediately and site waits bet again.
I haven't played this yet, and I'm curious how this hash verification works. If I understand correctly, you display the sha256 of some unique data, AKA "secret" before the player places his bet. Then the player bets whatever amount they like up to 15 BTC, and is shown the ring that was hit, along with the "secret" used. While it is easy to verify the secret matches the hash, I don't understand is how the "secret" relates to which ring is hit, as that would be the most important part to verify that the game is fair.
It determine coordinates of the hit by getting first 4 bytes from this secret number. For example:
hash of secret: 4d1cb8895e10ed6f6dfc0013049df07f7e9794fd716b3b8e509f6581f2b934e3
After accepting your bet you will see secret and coords of hit:
secret: 0d37cc844521dbfdb92399be793a1bc3
x=0.05162127107652399481 (d37 / ffff)
y=0.79890135042343785763 (cc84 / ffff)

I would say that it impossible to *know*, randomness and fairness are very often debated in maths universities and school playgrounds and it is a subject that is easily mis-understood (which is mostly why people gamble).
However, I have done a lot of gambling and poker over the years and the successful houses are the ones that are trusted - especially in on-line gambling.
That is why the more respected sites continue to plow so much resources into spotting cheating and robot players, because -in poker and other games of skill fairness is important, not so much with pure random games, where the honesty of the house about the odds is important.
The successful houses know that the easiest way to do this is to actually be fair, take your cut, be open about it, and you will still make a fortune.
As soon as a site is rumored to not be fair they shed players massively - even though such rumors are usually false - at least with the established providers, so it is just not worth it to cheat in providing gambling services - unless you are a very short-term scammer, who wants to make a quick buck and run. Which would be stupid as you will almost certainly make more money in the near to long term by being honest.
I don't know the provider of this site, but I have played it and I do like it.
Just responding to that particular question.

hmm am I doing something wrong, I've sent a bet to the acceptor address and it has currently 6 confirmations. Going to the main page, I just see my address in the field and acceptor address and a New Game Hash near the bottom. When I click Ok nothing happens.
Figured it out, I guess I missed the animation that I missed the target altogether

What are you referring to in that statement? The total income of your website??! If so, that's sad; you need a better business strategy... fast!
This is advertising, this amount casino already paid to players!

Also, on another note, regarding the lost Bitcoins I talked to you a while back about, I can't find the exact acceptor addresses I sent the Bitcoins to, but I do know the withdrawal address I used was 1MSgUtNsS2Nmfd4NH9ocXMhKRHoCAHEHKv. I hope that helps...
