Only need one that counts.
So let me ask again. Why is the game over as I stated and you are the winner?
Perhaps the game is over because of an unwritten bylaw ending it at 6 am. Although you posted game over before 6, there was no room for more valid posts before 6
Perhaps cheating ends the game.
Perhaps the sheriff is taking liberties to announce game over for reasons known only to him.
In any case, as the last valid response, I am the winner
