Average line sudoku
(Eingestellt am 4. Juli 2023, 03:44 Uhr von Nylimb)
Normal sudoku rules apply: Fill the grid with digits from 1 to 9, so that every row, column, and 3x3 box contains each of the 9 digits exactly once.
The blue lines are "average lines": In every group of 3 adjacent digits along a line, one digit is the average of the other two. For example, a line of 4 cells might contain 2135; 2 is the average of 1 and 3 and 3 is the average of 1 and 5.
I'm giving this an initial difficulty rating of "hard" because the break-in is a bit tricky. After that it's fairly easy.
Lösungscode: Row 2 and row 8.

Box 4 was a bit tedious for me. I knew a rule of thirds and identified a triple, but I felt I had to eliminate many potential chains before proceeding. I probably missed an easier way. Good puzzle idea though! This might be the first puzzle where I had four boxes completely solved and not a single mark written in the other 5 boxes! Thanks for the puzzle!

@bodemeister: Thanks for your comment. I've added a hidden comment showing how I get boxes 4 and 5.

Very fun puzzle! I hadn't done a average line sudoku before, so the logic was difficult to comprehend initially, but it went smoothly once I started making progress.
@oxjphs: I'm glad you liked it. As far as I know, this is the first puzzle with this rule, although I wouldn't be surprised if someone has made one before.
