U.S. National rules say:
"It is possible for a toppled kubb to be knocked over, then through the course of motion, to come to rest standing on one end. In this case, the kubb is still considered toppled, and is customary to put a token on the toppled kubb." (U.S. National Kubb Championship® Rules V3.1, Section II.B.10)
I'm curious about the customary tokening.... Has anyone done that? What would that look like, exactly?
