Today we have another amazing puzzle from Cubic Dissection. This one is Stumbling Blocks designed by Pit Khaim Goh. It is part of the Artisan Collection, so it is kept in stock and for $39, this piece should be in everyones puzzle collection.
To start with, the puzzle is gorgeous. The box is made from Ash and the blocks are made from Walnut and Sepele which gives a really nice contrast and checker pattern. The puzzle is shipped unassembled, so it is up to me to get the four blocks into the box.
There are a few peculiar details that stick out right away. The first is that the inside of the box has tiny little wooden triangle blocks glued into two of the corners. These blocks fit perfectly with two of the blocks that have notches cut out.
The other thing that I noticed is the way the blocks are glued together and the interesting shapes that are sandwiched between the two squares of wood. It seems peculiar to choose the particular shape for the sandwiched pieces.
So, with those details noted, I began to play with the puzzle. It seemed obvious that the two particular blocks had to fit into their specific corners – however, this “fact” didn’t seem to help with the solution. It was fairly simple to get any 3 pieces into the box, but there was never any room left to insert the 4th.
Over and over again, I tried the same thing and failed. I could see no way that the 4 blocks could be inserted sequentially. There had to be another way – not to mention the website mentions an “ah ha!” moment when solving this puzzle. So, I kept at it, searching for the solution.
Eventually, I managed to get all 4 pieces into the box – however, I did not experience any epiphany, so I was pretty sure that I had solved it incorrectly. To solve it, I sort of had to wedge the last piece in – which although it works and takes no force, is clearly not what the designer had in mind, so I pulled the pieces and began again.
This time, I had the breakthrough, or at least part of it. I inadvertently discovered a certain movement while I had 3 of the pieces in place – I knew immediately that I was on the right track – but it still took me a while to figure out how to get that 4th piece inserted.
Once I uncovered the real solution, a big ole grin came over my face. Now I know why this puzzle came so highly recommended. It truly is a clever and elegant solution. The rush I get from completing puzzles never gets old, but this one was special, this one was definitely memorable.
