The puzzle consists of a five layer sandwich with six sliders and the goal is to navigate the sliders to their outer most positions. Cut into the sliders are maze paths with pegs within which restrict their movements. Somewhere residing in the middle is a small marble that will also hamper the movement of the sliders unless the puzzle is oriented correctly.
Designed and made by Jean Claude Constantin, All Shift comprises of laser cut wood, acrylic and plastic. Good overall construction and finish throughout. However, I did find moving the sliders a bit stiff at times, but I guess this can't be helped given the puzzle has multiple sliding and moving parts.
Overall a nice design concept with a different application of "N-ary". For those who are into this category of puzzles, the All Shift is worth considering. It is available on Hendrik's online store.
