This puzzle requires some very tricky 22 moves to remove the first piece from the assembled shape. Although a few pieces tend to rotate during the solving process, there seems to be no shortcut solution using rotational movements. It can be solved using rotational movements, but it still requires about the same steps as a rectilinear movement solution, though it is tricky to count while it involves rotational movements. The number of possible assemblies of the puzzle is a very large 30,592, and finding the unique solution among them is extremely difficult.

Once assembled, the puzzle looks just like an ordinary 6 board burr, but as you can see in the images below it has been designed using a grid system of half unit lengths. It doubled the number of moves for the first piece compared to an ordinary 6 board burr that has a maximum 11 moves unique solution. One of the most difficult aspects of designing this type of puzzle is to ensure that the puzzle has a unique solution. To achieve this, Juno has carefully modified the shape of a couple of pieces, which are cleverly hidden in the images below.

We bought a considerable amount of full width Bubinga boards from our favorite timber yard a while ago and we found a lot of pale colored sapwood. Juno thought that by separating the heartwood and the sapwood, it would be possible to produce an original plywood with a clear contrast in color. The puzzle temporarily had a rather boring name something like 6 Board Burr X2, so we named it Bubinburr thinking about the material used.

The solution to this puzzle will be supplied upon request by Burr Tools file format.
