After a quick reminder on Butterflies, this took me about 20 minutes. So, not that difficult! You are always going to get extra clues which limit the options once you have a few placements in outer nonets. r16 options were very quickly filled in. Still fun to do – thanks.

Definitely fun, I really enjoyed it. One note though – the solution would not download for me, clicking on it (using a Firefox browser) just returns back to the main page.

I agree — I tend to find it difficult at first adjusting to a Butterfly, then the rest is rather mechanical. But fun anyway.
