The 7 Move Phillippe Dubois Aluminium Burr is a striking example of precision craftsmanship. Milled from solid aluminum with exact CNC techniques, it feels cool, heavy, and impeccably clean in the hand. Its six identical-looking pieces slide together smoothly, concealing a structure that is anything but simple.
This burr requires seven deliberate moves before the first piece can be released. Since there is only one correct sequence, every move must be intentional. The interior features voids and unconventional geometry, eliminating the idea of a single locking element. Instead, the puzzle depends on a delicate balance of alignment and movement, creating a difficulty that surprises even seasoned solvers.
Those familiar with the 10 Move Piston Burr will recognize the profile, yet the internal design is entirely different. The two puzzles can even be combined to create new hybrid challenges, providing added exploration for collectors who enjoy experimenting with variations.
Reassembling the puzzle truly tests patience, spatial memory, and intuition, as no guiding solution is included. The process is quiet, methodical, and deeply fulfilling.
Each block measures 22 millimeters by 22 millimeters by 66 millimeters, giving the puzzle a compact, architectural presence. True to the legacy of puzzles crafted by Wil Strijbos, the enjoyment comes from discovering the solution yourself.
