In order to make sure that the Integrity Check is reliable, let's do some analysis of the actual Client Secret, which is located in your account settings.
Open any encoder that accepts SHA256, for example:
Beforehand we take a screenshot from the profile where our Seed is, we will use the screenshot above as a reference.
In order for us to perform an Integrity check, we need to get the value of Server Seed.
Open your account settings on the site, scroll down, and update the client secret.
We have replace it, we now have a new Seed.
Copy Server Seed from the Case itself and paste it into the hashing string on the specified sites from point (1).
Get the Server Seed we had earlier.
We compare the received value with the Server Seed string from point (4).
This proves that we cannot influence the result of the game in any way.
