Just another quick update --

We've revamped the Chat feature to be more integrated with gameplay.  We think it's crucial to be in that chat room right away!

We also added a like a volume slider.  We've started putting together plans for new pay tables and a progressive jackpot.  Stay tuned:)

Just deposited and played through BTC0.1.  

Nice interface.  Basically classic video poker.  My only recommendation to players is that since it is only full-pay at the max bet, don't do anything but that.  

A progressive would be nice, as long as the drop isn't sick.  Other variants like double double bonus and deuces wouldn't be bad, either.  

Cool, thanks for the comment.  We're in talks right now to figure out what we want to do for progressive jackpots as well implementing other pay tables (deuces wild, etc).  Look for it in the future:)
783  Economy / Gambling / Re: BitcoinVideoPoker! -- retro Vegas video poker at its finest! [UPDATED] on: December 18, 2012, 06:23:14 AM

Yet another update to http://BitcoinVideoPoker.com/ is live! 

New Features

  • All new dynamic leaderboards.  You can watch things update in real time as you and others play.
  • "My Games" are never forgotten.  Reloading and returning to play will show your old games.

Improvements

  • The provably fair dialogs has been consolidated into a single location in the My Games tab. We added a verify button so that it's much easier to notice!
  • Twitter and facebook posts include your double down results.
  • Better sound effects.
  • New help dialogs and information.
  • Lots of attention to site load speed and size. Site should load even faster.

Fixes

  • We've done some work to get the site working with Internet Explorer.  All bets are still off, but things seem to be working.  Please report any bugs you find!

Come and visit us:)   We're also talking about more things to implement.  Would people rather see:

  • An autoplay button, where you can just sit back and watch games being played, or
  • an "assistant" that recommends which cards to hold,
  • A progressive Jackpot of some sort?
  • Or any other ideas?

Thanks!

We're thinking up some ways to make the provably fair stuff more visible.  We want to make sure everyone knows that each and every one of our games are legit.  The data is there, we just need to make sure there's something that says  "here's the proof!" is clearly accessible to anyone that wants it.  Stay tuned:)

In order to be provably fair you need to allow the user to 'cut the deck' in some way.  Otherwise all you're doing is proving that you decided which hand to give the user before they played rather than during.

If you don't take input from the user after providing them with a hash of your secret then you could still be skewing the distribution of hands in your favour.  It needs to be set up such that there's no way you can 'throw away' high value shuffles.

https://techblog.bitzino.com/2012-06-30-provably-fair-shuffling-through-cryptography.html is a good discussion of the topic.

As a matter of fact, the game already does this!  You can check the JavaScript code in the /static/ directory on the site but here's how it works:

  • Before you ever hit the DRAW button, the server picks a random seed for the next game, should you decide to play.  The seed is hashed and the hash is sent to the client.
  • When you hit DRAW, the client also picks a random seed and sends the seed to the server. This is what you called "cutting the deck."
  • The server uses both the server seed and the client seed to form a new game seed.
  • The deck is shuffled using the game seed and the hash of the deck is returned along with the hashed game seed.
  • At the end of the game, the server sends you the original server seed, game seed, and the deck.  The client verifies that the client seed was indeed used in the making of the game seed, that the server seed led to the correct hash provided before the game, and then verifies the game seed led to the deck that was actually used and THEN verifies the proper poker hand evaluation to make sure the prize is legitimate.

If you click on the links in the my games tab, you'll see all this information right there for you.

* I see point 4 of your 5 points is "Games are provably trustworthy" but I'm not seeing anything that proves the games are trustworthy.  Is there somewhere I'm meant to click to 'keep you honest'?

Perhaps the link isn't clearly visible.  Complete a poker game and then in the 'My Games' tab, the result of your hand (Nothing/Jacks or Better/Three of a Kind) text is clickable.  That dialog shows all the info for provably fair.  Moreover, you can browse the JavaScript files in the /static/ directory on the website.

Thanks.  I didn't think of looking down there.  Those tabs are kind of conceptually on a different page (I have to scroll down to see them).

Hey -- looks like I was bit misunderstanding of the issue at hand here.  Our leaderboards obviously need a bit of improvement if you're pointing this out.

Currently only the 'My Games' tab updates after each of your games.  The other tabs are loaded once when the page loads and that's final.  You've convinced us that more dynamic leaderboards are very important so those are the next thing to be upgraded.  Look for those in a few days.  As it stands now, the My Games tab is only data stored in javascript. so when you refresh it is not repopulated.

With new leaderboards, your 'My Games' table will be refreshed upon reload and the other tables will update dynamically with others' and your big wins.  

Sorry for any confusion:)

My Games doesn't show any results.

What do you mean?  Perhaps try clearing cache?

The wallet is spent now so I'll share the URL:

 - https://bitcoinvideopoker.com/?account_key=1040830816df7889a97e9c090c6ba337

I played a couple dozen hands.  But now when I click the My Games is doesn't show anything.

This is on Chrome.  I didn't try any other browsers.
787  Economy / Gambling / Re: BitcoinVideoPoker! -- retro Vegas video poker at its finest! on: December 12, 2012, 04:10:28 AM
I just tried your game out.  I must say it feels good to play.  Very fast and responsive even on my crappy Internet connection.  The keyboard interface is a nice touch; it certainly makes selecting which cards to hold a lot quicker.

I don't have a lot of criticisms, but here's what I came up with:

* I see point 4 of your 5 points is "Games are provably trustworthy" but I'm not seeing anything that proves the games are trustworthy.  Is there somewhere I'm meant to click to 'keep you honest'?

Perhaps the link isn't clearly visible.  Complete a poker game and then in the 'My Games' tab, the result of your hand (Nothing/Jacks or Better/Three of a Kind) text is clickable.  That dialog shows all the info for provably fair.  Moreover, you can browse the JavaScript files in the /static/ directory on the website.

Quote
* I had to reload the whole page before my play showed up on the 'recent' tab.  And doing so seems to have cleared the 'my games' tab.

Really?  Sorry about this.  If you had been to the website before it could have been a caching related issue.  Let me know if it happens again.

Edit: Sorry. I misread what you wrote here.  We understand the leaderboards need some work to be more dynamic.  We're working on that now and will update you all when the leaderboards are much improved.

* The competition (bitzino.com and play.luckco.in) both pay out 800 for a min-bet royal flush, whereas you only pay 250.  play.luckco.in encourages 5-chip play by only having the progressive pot available to max bet players.  bitzino seems to be flat-rate - you get 800 times your bet for a royal no matter how much you bet.

I discuss this with the other programmer here.  We went with the odds from vegas (250 as the min bet RF payout) to encourage 5 bet play.  Once we implement a jackpot perhaps we can give all plays the same odds and keep the jackpot on the 5 bet column, like how play.luckco.in does it.

I keyed in the payout table for Bitcoin Video Poker (flush paying 4:1 instead of 5:1, jackpot 4000) and the rake comes out at 1,6%.

Where's "Bitcoin Video Poker", with a lower flush payout?

http://bitcoinvideopoker.com/

Slick interface, but yeah, it's got more rake, no prog jackpot and no quizzes for free moolah.

Quote
I thought this play.luckco.in had the standard flush payout.  (It's currently down, so I can't check).

play.luckco.in is "full pay, nine-six" jacks or better, yes.

For what it's worth, we've updated the pay schedule to be full 9-6.  We're working on doing some kind of progressive jackpot, too.

793  Other / Beginners & Help / Re: Introducing myself and announcing publicly my new Bitcoin Video Poker website! on: December 11, 2012, 07:20:28 AM

Are there better payouts for video poker?  We can definitely reconsider the payout schedule.  At 5x bet, the game should be over 99.5% return.

We're also working a double down feature that some Vegas-style versions of video poker have.  Look for it in the future:)

The game you have set up - I have played it a fair bit when the excellent (though less professionally interfaced) competitor play.luckco.in has been down - is a "9-5 jacks or better" machine, which has a 98,4% return with perfect play (I calculated it yesterday, I think). The "full-pay" structure you refer to, with 99,54% return assuming perfect play and a fixed 799:1 (4000-credit) RF jackpot payout, pays 30 credits for a flush on a 5x bet rather than 25.

Nonetheless, your game is mathematically similar to SatoshiDICE and much better than most video poker machines I've seen outside of Las Vegas. I give it a reasonable thumbs up, and a much bigger thumbs up if you upgrade it to a full-pay machine as described above ("9-6 jacks or better").


Thanks for the thumbs-up and the tip on the odds.  I'm going to have a meeting with the other guy on this project and discuss upgrading to a full pay game.  I don't see why he would have any objections.  We'll make the change and do some play testing and then probably have the new odds up in a couple days, if not sooner.  I'll keep you all posted on this thread.

I have another opinion regarding vigorish and advantage play. If you offered some kind of progressive jackpot, say, by adding 1% of each wager into this jackpot pool, combined with a "9-6 JoB" payout structure as described above, the theoretical payout would rise to 100,54% (unless I'm mathematically impaired), but I think the House would still turn a profit, because few players play perfectly, thus donating money back to the House. Why don't real-world casinos offer more ultra-loose loss-leading games like this, I wonder? In Australia and New Zealand the casinos are known to give away free money in prize draws, sometimes $10k or more! as loss leaders, the only caveat being you actually have to be present in the casino at the prize draw when it takes place.

We have actually been discussing having some kind of progressive / jackpot play.  Look for it in the future:)
794  Other / Beginners & Help / Re: Introducing myself and announcing publicly my new Bitcoin Video Poker website! on: December 11, 2012, 04:32:12 AM

e-mail? Seriously?  

E-mail is a clear text transport method, and thus is not good for sending URLs which have the ability to claim and/or withdraw bitcoins.

What's your GPG key so that I can encrypt it first?

Well, actually, I think we discovered the problem already.  We use SoundManager 2 to play sounds in a web browser and on some systems the module doesn't load completely, leaving some sound items 'null' or undefined.

You don't need to send me your URL as it looks like the problem is entirely in javascript.  Indeed, line 248 (videopoker.js) is:

sound_pay_coins.play();

Which means the sound module didn't load on your machine.  We already have a fix for this and will be pushing it up shortly.  I'll post in here to let you know when the fix is live:)

Instead, I'll announce and hang around here and be of assistance to anyone who needs it.

I like how it acknowledges my deposit in real-time.

But I'm stuck now though.   So I have credits.  It shows Bet 1.  I click Draw.   The Credits counter drops by 1.   The box goes grey.   And I can't do anything else.  No cards turned over.    

I can reload the page and the Credits counter reverts to the full amount that I deposited.

I am on Chrome on Ubuntu.

[Edit: Also, the deposit address could use a way to show it as a QR code, for those who pay from a mobile.]

OK, thanks.  Sorry for the issues -- can you E-mail admin@bitcoinvideopoker.com the URL to your account?  Also, can check for JavaScript errors before sending that E-mail?

It very likely could be a browser incompatibility, and I'd like to get it fixed:)
797  Other / Beginners & Help / Re: Introducing myself and announcing publicly my new Bitcoin Video Poker website! on: December 10, 2012, 07:18:28 AM
Not bad. simple deposit mechanism, fast play, decent (if a little tight) payouts.

Are there better payouts for video poker?  We can definitely reconsider the payout schedule.  At 5x bet, the game should be over 99.5% return.

So your question is -- will you ever be able to buy 1 oz of gold with 1 BTC?  I suppose it's a possibility.

Right now the value of Bitcoins are such that it takes 126 BTC to buy an oz of gold.  At one point it took 3400 BTC to buy gold.  I'd say it's on the right track:)

Hey everyone, I'd like to introduce myself.  I'm a longtime lurker of these forums and a longtime lover of Bitcoin.  I'm a developer (15+ years experience) in gaming, websites, and more.  My friend and I were inspired by SatoshiDice to get involved in the gambling aspect of Bitcoin so we developed BitcoinVideoPoker.com.

At first I just wanted to pass my website information along to mem (for his gambling website list) and be on my merry way, but I'm thinking now that is probably not the right way to go about business.  Instead, I'll announce and hang around here and be of assistance to anyone who needs it.

So that's that.  Check out our website if you're bored or interested in video poker.  We went for a retro Vegas look and feel.  The game is Jacks or Better and the top payout is 4000 to 1 on a Royal Flush.  We require 0 confirmations to play, but 2 confirmations on your deposit before you can cashout and the minimum cashout is 0.02. 

http://BitcoinVideoPoker.com/

I'll be hanging around to answer any questions to take feedback.  Thanks:)
