I am not the best solver but found this one easy. Maybe 1.5*

Surely a 2* ;)

Nice puzzle but as others have pointed out, it’s nowhere near a 1* (I’d say 2*, but closer to 3* than 1*).
-- Perhaps this is an insight into how people are inclined to rate the puzzle at the difficulty it was posted with. This was a tough one to rate imo, easy if you look in the right places, hard otherwise. I now agree with 2*, but not sure if I can actually change that anymore -Cassinii

level 1 means you can give the puzzle to a beginner, and they can do it without coffee.
does this qualify ? not even close.
level 2 means you can give it to a beginner, and they can do it ... somehow. does this qualify ? probably not.
assuming, of course, that the ranking system actually has a consistent meaning.
and yet ... this puzzle IS "very easy", even for beginners, as long as you focus on studying the behaviour of the 68 pair.

Nowhere near a 1*, a solid 2*. Good puzzle, just far too much insight needed for this to be considered 'very easy'.

Great puzzle, thanks Cassinii! I made a video of solving it for my YouTube channel -- feel invited to check it out! It also includes some backtracking as I made one error in the middle... :o https://www.youtube.com/watch?v=xvoN8E5Kjc0
-- Just watched your solve, great job! Left a comment ;) Thanks for solving!

I hit a wall early, thought for sure it was beyond me, and then the clouds parted, the sun shined, and I was enlightened. Wonderful, wonderful puzzle.
