It’s surprisingly simple, actually.

Basically, there's three grabbers, three taggers, five twig runners, and a player at Whackbat. Center tagger lights a pine cone and chucks it over the basket and the whack-batter tries to hit the cedar stick off the cross rock. Then the twig runners dash back and forth until the pine cone burns out and the umpire calls hotbox. Finally, you count up however many score-downs it adds up to and divide that by nine.
