It was my first thought as well ;) But the article doesn't do the comic strip justice.

Thank you. This is the best description of the concept :) I also think that the existence of the permanent rule in the game (unique moves) makes it more engaging.

Thanks for making my evening.

This was also my initial thought. Mao as well...

Mao was my first thought too.

I'll admit that my second thought was the "make a rule" rule of Kings...

"The fictional game Calvinball, played by the main characters in the comic strip Calvin and Hobbes, is sometimes compared to Nomic. However, Calvinball appears to have a permanent rule that the same rules may never be used twice; a nomic, at least in its initial state, has no truly permanent rules."
