Where the original Hungarian Rings only has two interlocking rings made up of 38 balls in 4 colours, this version has five rings made up of 72 balls in 5 colours.
This version is a much harder puzzle than the original. I haven't managed to solve it as yet but thought I'd share it here anyway as an interesting and quick addition to my last post.
It's a shame that these are so hard to come by because I think that they look brilliant as part of a collection, plus they're definitely not trivial to solve! But as with all rarer puzzles, keep an eye out on those auction sites as they do tend to pop up every now and then.
