Cavern Crawl 2: Arrows
(Published on 5. September 2021, 00:00 by Nordy)
Navigate the caverns with the help of arrows in this sequel to Cavern Crawl.
Rules:
Normal Sudoku rules apply. To distinguish the boxes, each 3x3 box is shaded completely green or completely white.
Digits along arrows must sum to the number in the corresponding circle.
Horizontally and vertically adjacent digits must have a difference of 3 or less except when separated by a “wall” (thick black line). Adjacent digits separated by a wall may have any difference. A 3x3 example is provided below.
Solve online using Penpa+. Use "Sudoku" and the rightmost "B" for answer check.
Additional version version with thicker lines, if preferred.
Solution code: Row 1 followed by Column 9

Thanks for the warning! Wall design is the biggest challenge for this puzzle type, and box edges add to that. For the next puzzle, I'll offer some more "additional versions" and see if those prove helpful.

I kept running into problems on the border between boxes 2 and 3, not realizing there was a black line there. I found it easy to fall into that trap when the line is along a box barrier. Other solvers, beware! :)
