The puzzle is to remove the ribbon from the elephant maze disentanglement puzzle. There are 11 different starting positions for the ribbon, rated from "tricky" to "very hard".
When you buy the puzzle from Mr Puzzle it comes with a drawing showing each starting position; this is only available at this website. The ribbon can be easily reset by undoing the joining clasp, take then ribbon out of the puzzle, and reset the starting position.
This is a very nice adaptation of the classic staircase disentanglement puzzle, known in French as Baguenaudier (very appropriately it literally means time-waster) they are closely related to the better known "Chinese Ring Puzzle" or "Devil's Needle puzzle".
This Elephant puzzle is a type of "n-ary" puzzle meaning each move has "n" number of state - in this case 2 states being binary. These types of "n-ary" puzzles have either 2 states - binary, or 3 states - ternary, and more.
