Thanks, very nice puzle, and very clear and beautifull solving path. For me definayely less than 4*. I am solving all your xv puzzles in publishing order and for me it was the best so far. Can not really understand why such beutifull puzzle has realatively so few solves. Maybe 4* scares poeple.

IDK how this works.. if I start coloring at one end everything seems nice and flawless until I hit a massive wall (tried at least four times) but when I start to color from elsewhere I get -what feels like the same pattern emerging- and it eventually solves!
okay, once I got the correct point to start coloring it's a 3* I think BUT that starting point is so not obvious (to me at least) that again I totally ignored it a few times on purpose...
Not having a "key" to a puzzle is a four star..
not even seeing the fricking DOOR for me is 5* ;-)

i can see why this is a four, but the thing that took me four times to get right, wasn't the tough logic that was certainly abound in a few places, it was the false deductions I added to the puzzle.
i will add that anyone who has been following this series should be able to complete this one as well. not a total departure.

This is definitely the most difficult one, so far. I had to restart it a few times before I figured it out. Thank you.

Thank you, I agree, I did put it up as 3-star. but it got voted 4-star

I really enjoyed this one (which is true for all puzzles of this series), while I see it more in the 3* area than 4*. Thank you for keeping these coming (and for leaving out further constraints to forget about :))

You're not kidding, I've been passively trying to solve it while watching the EUROs and I have just hit a wall I can't seem to find my way past
*edit - I restarted fresh and stopped numbering to reduce distractions, stopped looking at the wall, and found a gap, then eventually came back to untie the knots, pretty nice

This is the hardest one yet I think... good luck and have fun :)
