Instructions

Divide the grid into regions so that each region contains exactly one number from the grid. The number in each region must correspond with the perimeter of that region.

For example, if a square in the grid contained the number 4, the square would be in a region all by itself since the square already has a perimeter of 4.

The regions can be rectangles, but they do not have to be rectangles. For example, look at the 8 in the upper right corner of the example puzzle below. The region containing that 8 is L-shaped.

Puzzle Origin

When I originally learned about this logic puzzle, it was under the name “Knossos.” “Knossos” is the name of a palace on Crete and is part of many ancient legends.

When I discovered that this puzzle was really based on determining the perimeters of various shapes, I decided to rename the puzzles “Perimeter Puzzles” in my classroom.

This puzzle was created by Philipp and Valentin Hübner and first made an appearance in 2011.
