No, they aren't either. :-P
If you're serious, you either don't share the common understanding of language, or you don't share the common understanding of logic. In either case, it neatly explains why you think Zendo is broken and needs to be extended. I, however, don't see a need to change the game in a drastic way in order to cover your lack of acceptance of the truth of a statement like "all typewriters built on Mars have feathers."
Since Zendo relies on shared understanding of words and logic, you will have problems with it if you deny what has been established during thousands of years of serious thought.
