Eight Hex P Challenge

 

Laser cut Eight Hex P Challenge puzzle. It shows the piece outside isn't quite fitting and puzzle cannot be solved without re-arrangement of the pieces.

Introduction

Instead of polyomino and square grid used in the first replication puzzle, here we switch to polyhex and hexagonal grid. The basic building block is P-tetrahex, which looks like a letter P (and also like a pistol):

P-side of a P-tetrahex

and let's call it's reflection Q-side

Q-side of a P-tetrahex

This puzzle requires the filling of eight P-tetrahex into a frame as you can see in the picture above. The challenge is that only one side of each P-tetrahex can be used in this puzzle:

• 6 P sides
• 2 Q sides

The required sides have dot markings (the other sides are blank) in my laser cut file, and they must face up when you’re trying to solve the puzzle.  The picture below shows the frame and eight P-tetrahex pieces with dot marking sides facing up.  This puzzle has exactly one solution.

Puzzle frame at left, and eight P-tetrahexes at right with dot markings on 6 P sides and 2 Q sides.
