not provably fair, I'm out

Everything is quite honest: naked mathematical statistics, game public logs available.

How can you prove that the bets won wasn't you?

[lucif]

Propose me a sane method to proove and I will. So far I set up public logs for all real games. I think it's enough so far.

How can you prove that the bets won wasn't you?

Well, some are mine =) I like to play both blackjack and roulette especially on my own website. I enjoy it because of low house advantage.  I can play enough long time on not big balance. There are no privileged accounts. Its too difficult to program, especially if I want to expand game list. I register account, deposit money and play them out =) That is initial bank filling procedure.

However if there is not enough bank for player payout, payment is delayed for some time until I refill bank for enough amount.

I blindly believe to math statistics. Some day plus, some day minus. But overall house edge keeps itself. I hope this is enough.

If you don't believe I have enough coinz, I'm most known trader in speculation This is why I have orange nick - not everyone likes my predictions.  Hehe.

Lucif, you can do provably fair - Bitino does it for blackjack.  They use server seed, server seed hash and client seed.  They even provide a javascript verification program.  I like your interface, placed some demo games.  But noone will spend real BTC if you not provably fair like the competition.

[lucif]

That's good implementation,  but I think proprietary flash games I bought don't support js seeding. I'll think around if I can hack them.

Server side is completely mine and I can improve it. But frontends need binary hacks to implement this

[lucif]

Winners may give fair reputation so far =) And public logs. Public logs are hard to be faked if there is a good amount of players.

What can I say?  I like your GUI better, but as a gambler I want a guaranteed fair game.  The blackjack in Bitino of 1.45% house edge (a virtual 6 deck shuffle) and is provably fair.  For a little prettier GUI, who is going to take a worse house edge and no proof of fairness?  I think this casino will be DOA in the bitcoin community.

[lucif]

Hmm, let me fix something. According to this http://wizardofodds.com/games/blackjack/calculator/ my blackjack has house edge around 0.5%.

How do you figure? That site doesn't calculate for using 9 decks.

Can you explain the rollover in more detail?  The way I read it there is a 125x rollover and then I can withdraw whatever is left.  Is this correct?  Is there a place on the cashier page that keeps track of my progress with regards to the rollover?

[lucif]

It keeps track progress on bonus page

If you demand 100 credits bonus, you are required to make bets on summary 12500 credits.

[lucif]

Also
2. If you lost more than 100.80% of initial bonus, bonus is marked as played out in full.
3. If your balance is less than 50% of initial bonus, bonus is marked as played out in full.

Example. You got 100 credits in bonus. Since that time you are not able to withdraw bitcoins from account if you:
* Didn't make summary bets on amount of 12500 credits
* [OR] Didn't lost at least 100.8 credits
* [OR] Your balance is greater than 50 credits

So if you make bets on summary 12500 credits - bonus cleared and you are able to withdraw (if you didn't ordered other bonuses).
OR if you lost summary more than 100.8 credits - bonus cleared and you are able to withdraw (if you didn't ordered other bonuses).
OR if your balance is less than 50 credits - bonus cleared and you are able to withdraw (if you didn't ordered other bonuses).

So house advantage of a bonus is 0.8%. All these equations drawn from 0.8% house advantage (except last 50% balance rule - its just loyal).

Can you lower your house edge for Roulette?

[lucif]

0.5% - 1% on blackjack and 2.7% on roulette.

[lucif]

Of course, if I will blindly press HIT CARD on blackjack, the house edge would be 100%. It depends on strategy.

[lucif]

Can you lower your house edge for Roulette?

Ah, sorry. No, it can't be lowered in anyway. House edge on roulette is 1/37=0.027=2.7% (in cost of zero field).

Roulette house edge can't be lowered without breaking whole field. However it allows potential very high profit bets. Starting from 1 to 1 and ending 1 to 36 payout - you choose your roi expectation.

Lucif, you can do provably fair - Bitino does it for blackjack.  They use server seed, server seed hash and client seed.  They even provide a javascript verification program.  I like your interface, placed some demo games.  But noone will spend real BTC if you not provably fair like the competition.

I figured out how can I implement this without breaking front ends and I am working on provable fair implementation now. Watch updates.

[lucif]

Okay, now CaesarBIT officially provably fair!

Provably fair random engine

Our Bitcoin casino uses provably fair random engine to prove we use completely random engine. Our random engine uses random seed from two sources: server source and client browser source. Both seed sources generated before start of a game. Both client and server seed represented by 50 random integers.

Server random seed
This seed is represented by sequence of 50 random integers. It is hidden from player, but we provide a SHA-256 hash of this seed BEFORE start of a game to make player sure we will not modify this seed during game.

Player random seed
Player random seed also represented by 50 random digits. These integers generated in player browser using JavaScript randomizing functions. Player has ability to write down this seed and hash of server seed before start of a game to replay random items later.

Combining seeds
When our server needs to pick a random number, it uses both client and server seed numbers by XOR'ing them. The result number is used as seed for random generator.

Verifying random engine
You may write down browser seed, hash of server seed and full sequence of picked random items (ball number, cards of dealer and player, etc). After that click on a game link below to know server seed and download scripts to verify our random engine. Warning! If you do this during game, game will be abandoned and current bet will be lost. So when you view the active server seed, it will be outdated and all games using it will be abandoned.
You should launch verification scripts on your local PC, provide them seed data and scripts will replay radom items right in such sequence that were in your game (which used this seed).
