This dynamic cube is one of our hardest, and also happens to be one of our favorites. The Koncy Puzzle contains six pieces. Nothing connects these pieces to each other, or lets the cube retain its form, besides the unique and unconventional shapes of the pieces themselves. Dismantling this cube is a very complex and gentle affair. It should be done one step at a time, and is difficult in and of itself.
The 6 pieces slide apart and return to a cube. It is important to note the last piece to come apart as it is the last to be inserted as the cube is reassembled.
Once the shape is unraveled, getting it back into a cube turns out to be much harder than it looks . Fair warning: this puzzle has 47 steps to bring it back into a cube. Starting with a 3x cube is recommended.
Do not be deceived by the appearance. This devil of a puzzle consists of 8 piece that have triangles on three sides of each block. To solve the puzzle you must inter-lay the pieces back together so that all the triangles are inside of the cube.
