@mys being a witness is irrelevant to that case

Please make up your mind: are you saying that @mys is cool and you are rewarding him or that he is not cool ... and you are rewarding him anyway?

You've made a game with some rules and @mys played that game and was rewarded according to those rules.

The house always wins, except when is being surprised by people who can do math.

Simplifying:

There's a game:
You pick a number.
Then the house will randomly chose one.
If numbers matches, you win.
The house promise fairness, providing the code that clearly shows you when you lose and when you win.
What are the odds?
