This is the fifth version of the Grooved 6 Board Burr series, and its configuration is very similar to the first version. Also, the number of moves needed to disassemble the first piece is the same as #1, 22 but #5 has a tricky feature. That was the reason why Juno thought he should produce this version.

Remember that he is a person who always tries to outmaneuver others with his designed puzzles. Many of our customers may notice the true characteristic of the puzzle when they try to assemble it.

The grooves are set to have a symmetrical orientation when assembled to give unification, but not to spoil the unique solution. A few grooves are added or extended more than necessary. Thus, not all the grooves are used during the solving process. The number of possible assemblies is relatively small at 481, so finding which piece goes where might be possible without computer aid or any clues even though it is quite tough.

The puzzle is made of our original plywood. American Rock Maple is used for the outer layer and the darker timber used for the inner layer is Amora.

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