I bought this puzzle at a local market and the vendor could not tell me, what kind of solution this has. Is the ring supposed to come off completely? And does anyone know the name / solution to this?

One name for this type of puzzle is a "Disentanglement puzzle" as described by Wikipedia here.

There is an enormous variety of this type of string puzzle.

The metal ring should come off completely. It looks as though it will not pass over or through the wood or leather (?) ring at one end, but the white ball at the other end should pass through it.

In that case I have a simple answer, but measuring the metal ring and the white ball, I think it will pass over only the two smaller balls, in which case the following solution won't work...

Slide the metal ring down and over the white ball.
It is now captive by just the string.
Now pass the metal ring through the slit in the wooden peice.
Finally again pass the metal ring over the white ball.
The metal ring is released.

... but these are the type of operations you will need to free the ring.

  • $\begingroup$ thanks for your input. If I understand your solution, I'd have to slide the ring over the white ball and one string at the same time - which is not possible. I guess that only the white ball would fit, but the white ball plus a string is too much. $\endgroup$ – user19760 Dec 20 '18 at 20:26
  • $\begingroup$ Yes I came to that conclusion - the other two balls are smaller. $\endgroup$ – Weather Vane Dec 20 '18 at 20:28
  • $\begingroup$ yes, the two other balls are small enough and the brown ring is so big, that there is no way it can interact with the metal ring. $\endgroup$ – user19760 Dec 20 '18 at 20:31
  • $\begingroup$ It should come off. If you look carefully, the string does not capture the ring directly. It's a puzzle! $\endgroup$ – Weather Vane Dec 20 '18 at 20:32
  • $\begingroup$ thanks, I managed to do as you said, I just had to put more pressure into it. After that, the white ball plus one string was possible. $\endgroup$ – user19760 Dec 20 '18 at 20:37
