Get one man across a yard the watch has lit up. You cannot walk where a light lands — but your pieces can take the lamps out.
●Your walker steps one square at a time. It may never stand where a sentry is looking.
●Your helpers move like chess pieces and may take a sentry — but only a sentry nothing else is watching.
●Watch lines stop at stone. They pass straight over your own people.
·Nobody moves but you. The watch is a lamp, not an opponent — nothing here will ever come for you. Your move is the whole turn.
·Fifty yards. Every one has a par, and the last twenty have exactly one route.
