- It turns out that Winning Ways is wrong (gasp!), and the correct puzzle is:
-
- The ring fits over the lower spheres,
- The ring does not fit over the "useless" rings,
- The "useless" rings fit through the eye,
- The lower spheres do not fit through the eye.
-
- A couple of people told me how to solve the (corrected) puzzle.
- A couple of people told me they had solved it, and offered to email me the
- solution if required.
- One person read the puzzle sufficiently closely to notice that it is not
- possible, and told me what the correction is.
- One person checked in Winning Ways, compared with the real thing, and
- verified the mistake.
-
- Thankyou to everyone who responded.
