^ everything you just posted can still be provably fair by using a nonce value. That way, you can't seek ahead in the number sequence, otherwise the client will know (because their end result was not your result). As for the user picking hi and lo, you could also assign "hi" to black, and "lo" to red. Or, *gasp*, you could let it be at the discretion of the user.
Why are you just insistent on posting relentless garbage? Don't you want your site to be fair to your user base?
Another straw man. "Don't we want our site to be fair to our user base?"
Creating a false narrative and asking us to argue it is senseless. The insinuation is baseless. For the record, of course we want our site to be fair. That was the mission statement before building 4Grinz. Our site is not only fair, it's proven fair by real experts and software, including the outdated and untrustworthy Provably Fair systems.
