(Published on 28. September 2021, 08:00 by twototenth)
Normal Sudoku rules apply. Blue lines are lockout lines; the endpoints (marked by diamonds) must have a difference of at least 4, and the digits on the line cannot be between or equal to the endpoints. Digits separated by a black dot must be in a ratio of 1:2. ALL BLACK DOTS ARE GIVEN.
Solution code: Column 1 followed by Row 8 (18 digits, no spaces)
