Beware! How did fleet anchor to avoid mine field?
by Sam Loyd
The Puzzleland fleet of eight battleships steamed into port today and sought anchorage.
The port authorities pointed out a series of 64 mooring buoys arranged in square formation with eight on a side.
They gave the admiral a chart of buoys and told him he might moor his ships to them provided he placed them so that no two ships were in a straight line and no two in a diagonal line. To anchor in any other way, they said, would expose his ships to the peril of drifting onto the harbor mines.
It looked like a knotty problem, but the admiral was sailor enough to selve it before nightfall.
Can you moor the eight ships so no two are in a straight or diagonal line, using the dots on the diagram as buoys?
