  Introduction This is a beautiful  calendar puzzle  on hexagonal grid with two panels. Similar to the  square grid version , the left panel has months, and days of the week; and while the larger panel on the right displays the days of the month, as shown in the picture below.   Laser cut and assembled board at left, and ten pieces of polyhexes at right. This puzzle features ten polyhexes, as you can see in the image above. The two panels aren’t connected, so each polyhex piece can only fit in one of them. The goal of this puzzle is to show three hexagons representing the date (month, day of month and day of week), while covering all other hexagons (including the empty one next to 31) using the ten polyhexes.

Introduction The goal of this puzzle is to pack all eight identical tetrahex (4 hexagon cells) "P" pieces into a heart-shaped frame. 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 . Each tetrahex P has two sides: Each tetrahex P piece has two side, P side at left, and Q side at right darkened by engraving All eight tetrahex pieces have dark engraving on their Q sides, while their P side remain original wood color. The laser cut and assembled ready-to-play puzzle is shown below (showing 4 piece in P side and 4 pieces in Q side).

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! Laser cut, with heart-shaped frame glued onto base board, with six pentominoes on the side SVG file available at ATOMM  and MakerWorld

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.
