Apart from the face that there are absolutely no “dice rolls” involved. They are known deterministic calculations. Because in order to add “dice rolls” you would need randomness. You can’t have a non deterministic calculation involved, because that isn’t how computers work.

You’re essentially saying “take a knowable input, add true randomness, output true randomness using nothing but knowable inputs!”

And you absolutely can brute force it. Why would you have a single chance? Because of arbitrary rules?

As for true randomness, you’re getting a range of “extreme low to extreme high” which isn’t currently brute forcible.
