6BB Oddly Extended Version #02

The puzzle has a unique level 28-9-3-1-2 solution, far beyond version #01. There are some obstacles to designing higher-level burr puzzles. Higher-level burrs often require larger internal voids to allow the consisting pieces to move, but larger internal voids are likely to result in multiple, fewer numbers of moving solutions, making it difficult to provide a unique solution. Large internal voids can also cause consisting pieces to rotate. To overcome the above issues, Juno had an odd (sneaky?) modification to one of the pieces of this puzzle and It can be seen in one of the images below.

As we did on Crooked 6 Board Burr #2, twelve magnets were added to stabilize the puzzle. The polarity of those magnets also provides clues as to which pieces should be paired with which pieces. When we produced version #01, Juno made a simple miscalculation and made the puzzle significantly larger than originally planned. Version #02 is smaller and lighter, so even with additional work to add magnets, we could reduce the production cost of this puzzle.

Our original plywood, made of Ironbark and Damar Minyak is used for the puzzle. Ironbark is very hard and dense, but a bit brittle, so the work was quite difficult. Please understand that there may be very small hairline cracks, which should not affect the construction of the puzzle, on the end of the outer layer of the plywood. We have sacrificed a lot of timber but it was not plausible for us to eliminate half the amount of the timber stock. The pieces with significant defects were used for the 2nd-grade puzzles, but not for the regular products.

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