6BB Oddly Extended Version #01
Juno has been experimenting with several kinds of ideas to improve 6 Board Burr and this puzzle is one of them. If the length of the board burr pieces is simply extended from 6-unit length to 8, we can not expect higher numbers of movement for assembling and disassembling since the filled area (block) strongly restricts the possible movement. Simply extending the blank area (voids) also causes another issue since it makes the puzzle too unstable when being assembled. Then, how about extending the length of the pieces and partially extending the blank area?
The idea was very advantageous, and Juno immediately found several candidate puzzles that require up to 24 moves to take the first piece apart. Therefore, we might produce the second and the third version of the puzzle using different combinations of the pieces and we put #1 to the name of this puzzle.
The #1 has a unique level 19-11-4-2 solution and relatively small numbers of 84 assemblies. Juno believes that the puzzle has no possible rotational shortcuts although some pieces have room to rotate a little while assembling/disassembling. Of course, the puzzle is arduous, but some serious solvers will be able to assemble the puzzle not knowing the orientation of the pieces. Some of you might feel the similarity of the puzzle to his Grooved 6 Board Burr series when you play with it.
The puzzle is quite big, and it weighs 360g. It took about 3.5 hours just for CNC work to cut a set of 6 pieces. All the sharp corners are beveled.
The puzzle is sold assembled. The solution to this puzzle will be supplied upon request by Burr Tools file format.
