The "game design" link above offers insight into the rules and nuances of the game. Eg:
The King resorts to violence only when he is cornered and has nowhere else to go. It's below him to kill commoners otherwise.
If there's no unobstructed path for the King, he will take the highest-value piece in his vicinity. However if you might lose due to the board being full, then the King won't help you by clearing the board; he'll just skip his turn.
Also, free tip: The King's value is 1024 if you want to contemplate regicide.
Eg. Are new pieces random? Since the king can eat clutter does that prevent you from losing?
