Grooved 6 Board Burr #6 (JUNO)

Buyer to pay for shipping.  I will accept Venmo, zelle, PayPal friends and family, or wise.

This little beast requires a maximum of 35 moves among the Grooved 6 Board Burr series to remove the first piece from the assembled shape. During the solving process, you may feel that the pieces are no longer interlocking together, but none of the pieces will come apart in a simple way. A few pieces tend to partially rotate and become very unstable especially around 14 moves from the assembled shape but there seems to be no shortcut solution for the first piece using rotational movements. It is somehow like playing with cast puzzles.

The configuration of this version is very similar to version #3 but the shape of the pins is different. Juno was a bit reluctant to produce this version as it requires milling or drilling work from four directions, which is a time-consuming process and requires precision work. The middle layer of the plywood has to be thick to accommodate pins otherwise the pins cut through grain and the pieces lose durability. It ends up with a thinner outer layer of plywood and there is lots of waste material. Despite these hurdles, we have been able to keep the retail price the same as version #4, partly due to the slightly higher production lot size given our capacity.

The number of possible assemblies is 481 which is coincidentally the same as version #5. It will be very challenging to assemble the puzzle even if you know the assembly that can lead to the unique solution, so please refer to the images below if you lose track of the orientation of the pieces rather than relying on computer aids.

The puzzle is made of our original plywood. Satin Sycamore is used for the outer layer and the yellowish timber used for the inner layer is PNG Rosewood.

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