It certainly looks quite a fearsome puzzle for solvers and as I said it is at the top of their difficulty scale - yep, a Level 10 (Mind Boggling) on their 5-10 point scale. It combines a very complex set of interlocking rings, loops and also a medium length of string so what could possibly go wrong? To make it even more confusing there is a knot fused onto the centre of the piece of string which limits a ball to the top half of the string. At the far end is a large triangular ring and loosely on the string is the brass coloured ring which you are supposed to remove. As with this whole series of puzzles it is well presented in a plastic clamshell package which mercifully is made to open easily - I always seem to lacerate myself when I have to open this sort of sealed plastic pack! The puzzle itself is beautifully made with high quality anodised wire and good strong string. Due to the thickness of the wire you would need to be really quite strong to force it.
So just remove the ring on a level 10 puzzle involving string? Easy peasy!! Gulp! Hopefully there'll be no awful knots! None of the usual bloggers have reviewed it yet but there has been a single review left on the product page giving it 4 stars but claiming it was easy but fun!
