Dodadoo - Win Bitcoin while playing dices (Provably fair)

[ndnh]

You claim you are provably fair. Where can i set my client seed? Where can i verify my results?

Hi

you can see all that on the tab, fair play is located above right

Dodadoo Team..

If you cannot change the client seed then you are not provably fair.

we have exactly the same as other websites betting
We want you to trust in us, that's why we've adopted “provably fair” gaming. That way, each user could verify the randomness of the results of each day.

Every dice result is based in three parameters:

Server seed
User personal seed
Bet number
Server seed:

There's a different Server Key each day, and you could know our server keys for the next 5 years. You could download all those SHA256 encripted keys by clicking this link.

server_seed_256

In this other link you could get Unencripted Server Keys (UTC Time).

server_seed_post

Customer Seed.

When you get registered, Dodadoo assigns you automatically a 40 characters random seed, unique for every user. This customer seed key cannot be changed, but you can see it in your profile page. In case you are playing in demo mode, session ID is used as personal seed to get dice result.

Bet number:

It's an autoincrement number based in your bets.

In case you are playing in demo, then this autoincrement number is based session number.

 

How to calculate / verify results.

Bet result is calculated using the HMAC 512 hash of personal seed plus bet number, encripted with Server seed.

Let's see an example:

Server Seed (unencripted):
rcP0z4no614hhkdqRbzVK6BH015n
FKGlUWDyobhfzf6Ey7u9GU5etuz
RnRLhfikd

Customer Seed: my_user_personal_seed

Bet number: 2

Result: 5+3=8

Let's see how do we get the result:

Step 1: Calculate HMAC

With this online tool it's easy to calculate HMAC hash.

We only have to enter the Customer Seed followed by bet number (with no blanks) in “message”, and unencripted Server Seed in “secret key”. Then you have to choose SHA512, ant click “compute hmac” then we get:

2ef9acce1951ab35812ba456f59514bd03b
43c45cbcb30f80254f63dbf54c81cea75123
e4ce53df9eceafa761aab876d435e938f8a
5296d2650b25c89baf58af



Step 2:

We take first 5 chars: 2ef9a

Step 3:

We work with 6 faced dices, so we convert result from Base-16 (hexadecimal) to Base-6:

2ef9a (Base-16) = 4042442 (Base-6)

(Use this tool to try http://korn19.ch/coding/base_converter.php)



Step 4:

At the end, we take last 2 numbers from the Base-6 result, that is: 4 and 2

As Base-6 only uses numbers from 0 to 5, we only have to add 1 to this two numbers: 5 y 3.

Provably fair

So, from this three parameters: Server Seed, Customer Seed and bet number, it's possible to get bet result.

We cannot provide Server Seed, because any user could "guess" future results, just knowing personal user seed and bet number.

Thats why, we only publish Unencripted Server Keys at the end oh each day. You all can get ALL encripted keys, past and future: that way each user could check that used keys where the provided ones. So our bets follow “fair provably” pattern exposed.

Simulation

We've made 1.000.000 simulations with our provably fair method and here's our results:

Number 1: 334342 times (16.7171%)
Number 2: 333045 times (16.65225%)
Number 3: 332668 times (16.6334%)
Number 4: 333021 times (16.65105%)
Number 5: 334231 times (16.71155%)
Number 6: 332693 times (16.63465%)

If the user cannot change his client seed, the game is not provaby fair. end of story. which other site does not allow the user to change his seed?

ok

Allowing a player to change his client seed is a good thing, that said the current system is provably fair AFAIK.

The player has complete freedom to select the bet whether it is <5 or >6 or whatever. There is no way the site could cheat since the server seed for the day is pre-determined, nonce is known and the client seed is known.

Dodadoo Team..

are you ignore ndhc statement above about house edge calculation and your announcement that your site have 1.25% house edge instead 2.19%?
also i see there is a 50% deposit bonus , how much rollover for it? you might want to mention the bonus terms there soon

[ndnh]

are you ignore ndnhc statement above about house edge calculation and your announcement that your site have 1.25% house edge instead 2.19%?

They just removed the information from FAQ.

What is the house edge?
Comssion is included in our winning factors.

And house edge of 2.19% isn't a big deal, but it goes up to 1/3 of your bet (15 to 33 times the standard house edge)

Over 11, Under 3 : 30   (35.5497156)      16.67%
Over 10, Under 4 : 10   (11.8500474)      16.67%
Over 9, Under 5 : 5.5   (5.92498815)      8.33%
Over 8, Under 6 : 2,5   (3.554997156)      30.56%
Over 7, Under 7 : 1.6   (2.369998104)      33.33%
Over 6, Under 8 : 1.35    (1.69285811)      21.25%
Over 5, Under 9 : 1.15    (1.36730811)      16.94%
Over 4, Under 10 : 1.09  (1.185000474)      9.17%
Over 3, Under 11 : 1.011  (1.077272336)      7.32%
Over 2, Under 12 : 1,006   (1.015714518)      2.19%

The payout for 1.25% edge in brackets.

Why this is concerning?
If you wager 1BTC, and play on Under 7 or Over 7, you will, on average lose 0.3333BTC to the house, while in most other sites you will be losing 0.01 to 0.02 on average.

I got my withdrawal.


I didn't bother to calculate the house edge for "equal" but I am positive at least most are two-digits.

[simonloff]

The promotions both the deposit and the no-deposit are really interesting, How much is the overall volume of transactions the site has conducted till now or is that information private?

I went on your site and took the free gift. Gambled it up to 0.0018 and I want to withdraw. I have bet 30+ times as shown in the FAQ

(archive)

Yet this is what is shown when I try to withdraw:


Please fix this! My username is DarkStar, and you can check if I have made more then 30 bets. (I have)


Also, what is the rollover for the 10% bonus free to a deposit? Same goes with the 50% one I saw on your website.

Nice i like the free 10%. A definite addition you need will be the buttons, do you know when they will be implimented ? Keep us up to date.

I think I should still get a withdraw (after I deposit) , since when I did the 30 rolls when it was still like that. The archive proves it...
Now it's "2. If you wish to wish to withdraw our gifts, you have to wager at least 40 times the initial bonus received."

Do you have a page to track your bonus? Otherwise it might be harder to keep track if its done or not and it will be annoying to calculate everything.
