Moving the puzzle pieces following X, Y and Z axis, this puzzle requires 62 moves to take the first piece apart from the assembled shape. It might sound strange to some burr puzzle lovers and researchers. Of course, this separated board burr configuration gives good potential to have a higher level solution but according to famous Ishino’s website puzzle will be played, maximum moves pieces selection was already found by Richard A. Evans in 2012. His puzzle design Missing 2 has a 58 moves solution and it seems that the highest move selection is made sure by computer analysis. So, how did Juno cheat and gain another 4 steps? You may be smart enough to find out the secret of the mystery by entering puzzle data into a computer program, or by simply purchasing the puzzle and acquiring the solution data.
Like many other high-level burr puzzles, this puzzle has shortcut solutions using rotational movements. The puzzle also has a lower-level 18 moves solution. Not to have multiple solutions, sometimes puzzle pieces are colored or slightly modified changing the shape. Juno also found several ways to modify this puzzle to have a unique solution, but he didn’t take those options because shortcut solutions couldn’t be eliminated. He rather left the puzzle to have two solutions to keep a very fundamental 7 x 7 x 7 grid-base shape. Thus, he considers that the puzzle is a researcher’s item, or for someone looking for the highest level puzzle for a particular shape.
Our original plywood of Jarrah and Koto is used for the puzzle to keep the strength and durability of the pieces.
The puzzle is sold assembled. The solution to this puzzle will be supplied upon request by Burr Tools file format.
