Geeeez, this was hard to see! :))
Took me 45 tries, all together. Today's Yokosooo's comment encourraged me to try it again. I was at 120+, when I started and slowly made progress. Was held at 4 off, for a while and had at least 2 different 2 offs, before solving.
Thanks for encourragement, Yokosooo! :)
This was really hard for me. I couldn't solve this when it first came out despite several attempts. I forgot about it and came back and still struggled. Finally had in idea that paid off but really had to work for it!
