* Client seed is automatically generated in your browser using javascript.
This game is provably fair. What that means is that there is no way the site can cheat you by picking a number that is in our favour.
The way this works is that each spin is calculated using 3 parameters - the server seed, client seed and nonce. Out of these, we show you the client seed and nonce that will be used for your next spin along with a SHA256 hash of the server seed. You can also change the client seed if you wish (before solving the captcha). The server seed is the only part that is kept a secret until after the spin.
Then after you spin, we show you the server seed that was used and you can verify that this was the same server seed that we said we were going to use before the spin by checking if the SHA256 hash of this seed matches the SHA256 hash that we showed you before the spin. To know exactly how we calculate the spins, read the section below titled How are spins calculated?
1. Two strings are created :
STRING1="[NONCE]:[SERVER SEED]:[NONCE]"
STRING2="[NONCE]:[CLIENT SEED]:[NONCE]"
2. Then HMAC-SHA512 is used to hash STRING1 with STRING2 as the secret key, giving us a 128 character hex string.
3. The first 8 characters of the hex string are taken and converted to a decimal.
4. This decimal is then divided by 4.294967295 and rounded down to the nearest whole number.
5. This whole number is used as your spin, with the maximum possible value being 1,000,000,000.
