It has been absolute ages since I set a 4+ difficulty puzzle with only "standard" variants. The last time was Handshake, which was published in July! Well, that ends now. This puzzle is very intricate and I am pretty pleased with the deductions involved. So I hope you will be too! Enjoy!

Rules:

Sudoku: Place digits 1-9 in every single row, column, and 3x3 box.
Between Lines: Digits along a line must be between the values found in that line's circles.
Quadruples: Digits in a white circle must appear in the four surrounding cells.

Note: Regarding the lines in Box 5: The circles in Box 4 and Box 6 both connect to Box 8, but not to each other.

Puzzle Links: You can solve this puzzle in either F-Puzzles or in CTC software. CTC version does have answer check.

Solution code: First Row 8, then Column 4 (No commas or spaces, 18 digits)

Very nice break-in idea ! I've really enjoyed that and a couple of deductions in the mid-solve.

Really well set. I always felt I knew where to look, but I never knew what I was looking for, which is what I like most in puzzles. Impressive to capture that with rules so thoroughly explored

What an intricate and engaging puzzle till the very end! Really enjoyed the initial opening, and then a couple of crazy interactions in the middle, I was a bit slipped at that point too :P

Very beautiful and original logic. A true master combining two rulesets.

Vet nicely constructed puzzle. Everything clicks together in a really satisfying way!
Thanks for this gem

I kept making this puzzle harder on myself, looking for a long chain that would somehow disprove something... And then finally noticing a much more reasonable deduction. Very glad those chains never led to anything concrete, since this solve path is actually very straightforward (and hard to spot step-by-step)

Amazing puzzle. The logic really broke my brain, but it is fascinating how these constraints interact in surprising ways!

Lovely puzzle! What a great between lines workout. From the elegant break-in to the fun tricks along the way all the way to the ending, this puzzle utilizes quad clues and geometry in a way I was never expecting! Great stuff :)

Gorgeous :D

Very nice and hard! Thank you

Hard nut but doable. I had to use small bifurcations to remove candidates from circles when I couldn't figure out the logic but I always knew where to look for. Beautiful intricate logic.
