How the game got started

How did this game get started and why these rules?
 
Joel Pritchard and his friends Bill Bell and Barney Mc Callum decided to find a way to entertain their family's children on a rainy day in the summer of 1965. In this fifteen minute interview with Barney Mc Callum (recorded in December, 2009) he discusses how the game was conceived and how the rules were developed. Knowing why the rules are what they are helps us understand why it is so impoprtant for us to follow all of them.
