No, why? A user can use the same seed if they feel lucky or whatever. It just needs to be really provably fair and everyone can verify.

Ok. What about if a player has not spoke in an hour. Should i have a cut off time back to a blank string / their name?

I was thinking just keep a record of the last thing each person said.  Perhaps resetting it to their name when they log in to the server.

That is a good idea. With blackjack the initial shuffle is done upon the first placed bet and the last shuffle will need to be done when the round starts. This only gives a 5 second window to set your client seed by chatting. Unless i grab the last string the player said even if it was before they joined the round. (Maybe if they spoke in the last two minutes so it's still easy to scroll up on the client and see it)

I would rather it was something that I can confirm for all players.  For example, if you take the last thing said by each player who bet, and show that on the webpage, I can check that you have the right thing for all players.

If a player hasn't spoken, use the empty string for them.  Then I can say "go number 3!" before the off, and actually have it influence the outcome.  If a player doesn't care to change their seed (by talking) they don't have to, and they contribute the same to the seed for each event until they happen to speak.  Just a simple sha256(player1string|player2string|...) would do for the 'client(s)' seed.

What do you think?

Yes I have a few people bring this up. I am working on a new provably fair system using seeds generated by the players.

Here's my idea. Inspired by the bitZino double shuffle.

1) BitVegas shuffles the deck and supplies the hashed result.
2) Players place their bets
3) When the betting closes. All the X,Y,Z locations of the players with active bets are grabbed and added together to determine a new seed.
4) That seed is used to reshuffle the deck
5) The deck is used and the game is played.

Players will be able to see all the X,Y,Z positions on the verify page and confirm they were real. (You can see your position ingame on the client by pressing F3).
They will also be able to see that the seed was really used to reshuffle the deck and nothing else.

Let me know what you think and I will implement it. Or if it needs any changes.

I have to do things a little differently here as I have multiple players betting on one 'deck'.


Edit: I created this with bacon racing and roulette in mind. I just realized it won't work with blackjack as you are sitting and your position does not change. Back to the drawing board!
I could use the players YAW position (Seen by pressing F3 in-game and looking at the value) 'f'. This is the exact direction the player is facing and players can confirm it

Yes.  The same goes for pig racing and roulette too.  Some players will tend to bet more on long-odds pigs, others will more often back the favourites.  Some players favour red, some always bet on zero, etc.  But if the player plays randomly, there's no "bad deal".  In blackjack there is.

I think minefield can be a bad deal through. Humans are pretty bad at generating randomness, and some grids would be dug more often than others. The operator could weigh the mines to those grids more, giving them a higher house edge.

In fact this could be tailored to the player since it is a one player game - store a record of their grid digs, and personalize it individually.

One thing that occurred to me about the provable fairness:

For roulette, minefield, and pig racing, there's no such thing as a "bad deal" for the player.  You pick the result in advance, publish the hash, and the user can verify after the event that you chose the result before they bet, so you can't be cheating.  (Well, if a player is playing red over and over again you could deliberately pick black over and over, and publish a hash of you picking black before the player places his bet).

With blackjack however, there is such a thing as a "bad deal".  When you're playing against a single player you can deliberately pick shuffles which give the dealer blackjack more often than he should.

The way most provably fair blackjack sites (all 2 of them?) work is that they allow the player to provide part of the random seed, publish the server half of the random seed before the game, and publish the shuffle algorithm.  That way the casino has no way of picking preferable shuffles.  bitZino has this great writeup about how it works.

Currently your blackjack doesn't appear to be provably fair.  All you seem to be proving is that you picked the (possibly rigged) deck before the players played, rather than during or after.

Comments?

Our server was having some problems. No money was lost, it was just unable to connect to display your balance so it came up as 0

If you still have problems let me know!

Server just crashed- lost the .75ish I had. My username is success if that helps, but it seems to have happened to others as well. Other than that, its neat.

If you are ever looking for someone to help you with pixel art for the custom skin.. *cough*

This is great!

New game added today for testing:

Pig Racing

Quick question, I have the Minecraft mobile app for my Android phone, will this work on that?

Look forward to seeing you guys on!
