Provable Fairness Overview

This game is provably fair. What that means is that there is no way the site can cheat you by picking numbers to make you lose. You can take our word for it, but for the crypto-nerds out there, here are the gory details: When you click "Rerandomize(Change client seed)" we make up a secret random string (the server seed) that is used to randomize the rolls. You are shown the hash of the server seed, and are asked to supply your own random number (the client seed) to further randomize the rolls.

Current Seed Pair

The client seed currently in use:


The sha256 hash of the server seed you are currently using is:


and the number of bets you have made using it:


Rerandomize(Change client seed)

Each time you roll, the server and client seeds are combined with the number of rolls you have made since the seeds were selected to create the roll. Notice that you are shown the hash of the server seed before picking your client seed. This ensures that there is no way we can influence the numbers you will roll.


Provably Fair

7Double offers state of the art verification which allows our users to check the integrity of every roll and confirm they are not manipulated. Our random numbers are generated through the use of two seeds, a server seed, and your client seed. The server seed is created before you specify your client seed, ensuring that a server seed purposely in our favor cannot be generated. Together, along with the nonce (# of bets made with seed pair), the seeds are used to create a provably fair roll number within the 0-99.9999 range.

Seeds

In the provably fair tab, users can change and verify seeds used. To do this, click "Rerandomize" . Before you specify your own seed, you are shown the SHA256 hash of the server seed that will be used alongside whichever seed you pick. Changing the client seed used will also reveal the previous server seed, which you can then verify was the seed we hashed and showed you.

Roll Numbers

To create a roll number, 7Double uses a multi-step process to create a roll number 0-99.9999. Both client and server seeds and a nonce are combined with hmac-sha512(server_seed, client_seed-nonce) which will generate a hex string. The nonce is the # of bets you made with the current seed pair. First five characters are taken from the hex string to create a roll number that is 0-1,048,575. If the roll number is over 999,999, the proccess is repeated with the next five characters skipping the previous set. This is done until a number less than 1,000,000 is achieved. In the astronomically unlikely event that all possible 5 character combinations are greater, 99.9999 is used as the roll number. The resulting number 0-999,999 is applied a modulus of 10^6, to obtain a roll number 0-999999, and divided by 10^4 to result a 0-99.9999 number.

How to Verify

JS Verify
Copy the 3-line value from the "Rerandomize(Change client seed)" window into the first input of those pages and click "verify" for a list of the numbers you rolled.

You can use a third party tool to verify roll numbers or use the following Node.js script that recreates the proccess described above. It will output your roll number.

              
            //the seed pair itself
var clientSeed = "your client seed"; //dont forget to exclude the dash and the nonce!
var serverSeed = "your server seed";
//bet made with seed pair (excluding current bet)
var nonce = 0;
//crypto lib for hmac function
var crypto = require('crypto');
var roll = function(key, text) {
//create HMAC using server seed as key and client seed as message
var hash = crypto.createHmac('sha512', key).update(text).digest('hex');
var index = 0;
var lucky = parseInt(hash.substring(index * 5, index * 5 + 5), 16);
//keep grabbing characters from the hash while greater than
while (lucky >= Math.pow(10, 6)) {
index++;
lucky = parseInt(hash.substring(index * 5, index * 5 + 5), 16);
//if we reach the end of the hash, just default to highest number
if (index * 5 + 5 > 128) {
lucky = 99.9999;
break;
}
}
lucky %= Math.pow(10, 6);
lucky /= Math.pow(10, 4);
return lucky;
}
console.log(roll(clientSeed+'-'+nonce,serverSeed));
