# o A Hexomino Puzzle

Narrow Passage
Invented by Anneke Treep
Contributed by Michael Keller

 

The 35 hexominoes

 

The 35 hexominoes shown above (you can use a Sextillions set without the duplicate piece) can form a fully enclosed long passage no wider than one square at any point. The passage can twist and turn in any direction and even loop back on itself without intersecting.

What is the longest passage, closed at both ends, that you can make with the 35 pieces? The example below shows a passage of 20 units using only 11 pieces. Can you beat our best solution of 138 units, using all 35 hexominoes? Notice how the surrounding pieces must be connected on at least one full edge, not merely corners.
