/**
|

* Game of Chief
|

* <p>
|
||||
* Based on the Basic game of Hurkle here
|
||||
* https://github.com/coding-horror/basic-computer-games/blob/main/25%20Chief/chief.bas
|
||||
* <p>
|
||||
* Note: The idea was to create a version of the 1970's Basic game in Java, without introducing
|
||||
* new features - no additional text, error checking, etc has been added.
