Very cool puzzle, but I'm not sure if I've ever been less sure about my solve during the puzzle as I was here. Somehow my deductions "felt" correct but I was convinced it was gonna fail at some. point. :)
I really liked the break in as it required a combination of so many clues (for me at least). In the end 2-2,5 sounds about right (on LMD standards).

Disagree with Criptonight, this is definitely a 2... 2.5 at most. Lots of restrictions to work with. Excellent puzzle

Such a delightful work of art. Certainly harder than 2 stars, 3.5 to 4 at least.

Very nice puzzle, the constraints worked really well together, I really enjoyed how the renbans worked. Didn't use the region sum lines at all though, but it's never a bad thing to give solvers multiple possible solve paths :)
--- @gUBBLOR, my initial version didn't have all digits filled in the quads and it was quite a bit harder, and did require more stringent use of the Region Sum Line. I had 'simplified' the puzzle somewhat because it was intended to go into the CTC cell phone app - but in my testing, I had gotten so used to my same solution path that I didn't even think about trying it without using the blue line!
