KUBB, the game from the weekend of camping on Mount Tamalpais

KUBB is an outdoor or lawn game where the primary object is to knock over wooden blocks by throwing or tossing wooden batons.  Today's version originated in Sweden, and the rules vary from country to country and from region to region, but the ultimate object of the game is to knock over the five kubbs on the opposing side line, and then knock the "king" over, before the opponent does, the nickname of the game is "Viking Chess." Games can last from five minutes to well over an hour or two. The game can be played on a variety of surfaces such as grass, asphalt, concrete, sand, snow, or ice.  Here are my sketches of the game in progress at the campground.
