Inside the heart frame, there is a small heart island and all the tetrahex P pieces must fill around it. This puzzle is a combination of loose-packing puzzle and replication puzzle .

Pentomino Heart

Introduction Isn’t a heart-shaped puzzle just the best? The challenge is to fit six different pentomino pieces into the frame. With the heart’s smooth curve and the pentomino pieces’ straight edges, you might think there’ll be some gaps. And you’re right—this is a loose-packing puzzle . The fun part is figuring out how to position the pentomino pieces relative to the frame. Can you discover the perfect combination of packing and orientation to solve it? The great thing is, you can flip and rotate all six pentomino pieces as you work!

Three Fit, Two Times

Laser cut and assembled, ready-to-play Introduction This puzzle is a fun  loose-packing  challenge that pays tribute to the classic 4-piece  Marten's Menace puzzle. It features three pentomino pieces - F, W and Z- and the goal is to fit them into the frames on the board.  There are two frames in total, so you’ll have two puzzles to solve: one rectangular and one oval-shaped. Can you discover the best way to pack and position them all inside the frames? SVG file is available at ATOMM  and MakerWorld .

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.
