Did you add them yet?  I'm still getting 6:5 for blackjacks, and can't see how to split.

Do you think you need to show a couple more decimal places?  This looks silly.  "First dig is worth 0":

My host was having some ISP issues. Was resolved within 10min.

Dafaq is happening?

Crash?

Thanks dude! 

Whoever created this had a very good execution of this idea.

Did you steal my inventory? Also, I updated that post.

Thanks D35TR0Y3R

1. This has been a bug for some time and is now finally fixed.
2+3. This has been known since almost launch but has been on the low priority list. it will be fixed in the next patch.
4. Another thing on the low priority list but I will look into it

Hey mate. I have a ton of glitches to report. I'll make a list for ease.

1.  %commands work for everybody. People have been crashing the server by doing %100000b. The things we can do are: %b, %h, %n, and a couple other I thing.

2.  Stealing poker icons. If you are playing poker, and get out of your seat and run to the jukebox or fireworks box, and put your icons in there, wait for your turn to time out, and take them back out, you now own them. If you look in my inventory, you can see the fun I've had with it.

3.  Duplicating icons: Dump your icons in one of those boxes, relog, and now you have 2 of each icon.

4.  /me works for some people, doesnt work for either.

5.  There's no limit for how far way you can sit at a chair, so you can teleport from across the map into a chair, sometimes accidentally.

And now for suggestions:

1. Have a command to refill your inventory with the correct chips.

2. Open up the world to mining/building, for fun.

3. Have skill-based games (you have no clue how much I would love this)

4. Have a better prize for reaching the top of the secret room

5. Have a command for cancelling a bet

6. Make /help work

7. Set up a forum for discussion of the server

8. Hire me.

Here's a pic of my inventory for the lulz:

I wish I'd seen this before I upgraded. How exactly would I downgrade?

Hey everyone.

Update today:
Whenever BTC is displayed. It is rounded down. You should now see more accurate readings.
The deposit and withdraw system is back to 100% functionality. Deposits now instant again
The minimum withdrawal is now 0.005 BTC
Inventory is no longer reset when you relog. (Currently there is a bug where it gives you another help book everytime you log on)
Poker has reopened. There is a few bugs. Many of them are already fixed I just haven't pushed the next version up yet. Have fun testing!


Minecraft 1.5 was released. Please do not update if you still want to connect to the server. If you did update, you will need to downgrade.
I will be updating to Minecraft 1.5 when a stable version of Bukkit is released.
There is some very exciting stuff coming with this version which, if everything goes to plan, will include:
Your BTC always displayed on screen. (And any other text games need to display)
Names over the pigs heads.
HD textures and fonts (Where needed).
Animated textures if needed.

I'm dumb.  Why not just use the hash of the block containing the hash of the shuffles?  That's unpredictable too, unless he mines the block himself.  And if he can mine arbitrary blocks whenever he wants then nothing's safe...

That would do fine too. I like it.

It's a tradeoff between covering absolutely every way the house could cheat, and not flooding the chat with too much information.

Instead of "the most recent block's hash" they could just use "the next block hash after the block containing the hash of the pregenerated shuffles".  That's both unpredictable and fixed.

Interesting, I will try this when I get home.

But you still could. Look at it this way. On Friday the house shuffles all the card decks for the week's games (it has to be some time before the decks are used). For each game, it performs SHA256 of the deck, resulting in files like this:

Decks.txt:
MondayGame1Deck: KingSpades,AceDiamonds,4Clubs,..........
MondayGame2Deck: ......
...
SundayGame1000Deck: ....

Hashes.txt
MondayGame1Hash: sha256....
MondayGame2Hash: ......
...

So, you publish Hashes.txt on the preceeding Friday, and burn *it's* hash into the blockchain somehow.

Now at the start of each game, the players say their magic words, and these magic words shuffle the deck according to some fixed algorithm, and the game is played.

Now, in the event that no player says any magic words, or that JohnDoe is a regular player and he *always* says "abrekadabra", we need to prove that the house is not somehow filtering their decks (i.e. on Friday, the house shuffles their decks, applies "abrekadabra" and checks to see if the deck is favourable to them, given that JohnDoe comes in to play every Tuesday evening at 8pm). This would require an extra source of random shuffling from an externally verifiable source of entropy. e.g., the blockchain. So the shuffling algorithm need only insert an extra "lucky phrase", which is the block hash, or the merkle root, of the latest block in the block chain. Given that the house can't possibly know this value on Monday morning when they shuffle all their decks, this would absolutely prove that the house is not pre-filtering their decks.

After the game is played you allow the players to view:

1. the hash of the initial shuffle which is burned into the blockchain via the file Hashes.txt
2. the initial shuffle
3. the players magic words, the latest block|merkle hash, and the shuffling algorithm
4. the new shuffled deck
5. the play
6. the winner(s)


Oh... gosh, if we wanted to be *really* paranoid, the house *might* technically have a choice over which blockhash to use - the latest one, or maybe the one before that. If one or the other turn out to be more advantageous (again assuming the players say nothing, or say something entirely predictable), the house could claim they hadn't received the latest block at the time of the game. This would be solved by putting a visible blockchain counter in each gaming room though, or maybe writing it into the chat.

Hot damn, I should build myself a casino!

I think I prefer it how it is; it's cleaner, and every player can totally mess up any team of players' attempts to fix the deck by picking his own random words.

I do like the idea of having a pre-published list of house seeds, indexed by game number, and having the game number in the chat before each deal so I don't have to keep clicking on the green checkmark.

But I came here to say:

1) how about having a racecard showing the next few pig races, rather than just the next one.  Let me bet on multiple upcoming races at once rather than having to go back to the betting terminal between every race.

2) maybe add some copies of the existing games but for real-money players only.  Now that the casino is teeming with life (thanks to the millibit faucet) the minefield games are often occupied by playmoney players.  It would be nice if there were rooms which the playmoney players couldn't tie up.

3) did you say you added poker?  I didn't find it yet.

I'm on minecraft chatting with murderscene & dooglas about the provably fair betting. What I'd like to see is the sha256 of each game's "secret" *before* I play.
So, you could shuffle the deck, take the sha256sum, and write it in the blockchain the day before you use it. Then you take the user's lucky words, reshuffle accordingly, and play the game. On the results page (bitvegas.net/....) you can show the whole process which is verifiable.

EDIT: this allows the user to know that the original shuffle was generated before the game was played.

See http://btcmultiplier.com/keys.php for how they wrote a 40 year list (!) of sha256s into the blockchain with a single transaction.

Edit2: I'm just thinking, it would be far better to use a public source of entropy. For example, assuming a 3-player game in which no-one says any lucky words (or some people say predictable lucky words), what's to stop a casino from tending to favor decks with top cards: A,2,5,8,K,4,6,9, so that the dealer gets A & K blackjack! So the deck should be reshuffled with a random number just before the game, but that the random number can be proven to be outside the control of the casino.  e.g. btcmultiplier use the transaction ID.

In short, I'm saying that, assuming bitvegas is using, and not filtering in it's favor, a good random number gen, then the fairness is provable. It would be great if you could also prove the randomness.

Any thoughts?
