The esteemed, interlocking Construct Puzzle is based on an original design called "Chuck," created in 1897 by Edward Nelson. The design consists of 24 non-identical, interlocking Burr pieces. As always, the goal is to find the central piece that unlocks the shape. Then, you may begin the challenge of “constructing” the same shape that you just collapsed! The Construct Puzzle utilizes an ingenious slide-and-lock mechanism that requires a precise order when reassembling the structure. This high-level puzzle is the ideal challenge for serious puzzlers with extra time on their hands. Or, for those looking to build focus, patience, and spatial reasoning! All of these are crucial skills, and puzzle solving gives the brain a break from the constant bombardment of screens and technology. Once solved, the Construct Puzzle makes a stylish art piece to display on a bookshelf or coffee table.
