Palindromes 1:2
(Published on 7. February 2021, 01:00 by Lisztes)
Normal Sudoku rules apply. Each row, column and 3x3 box contains each number from 1 to 9 exactly once.
The grey lines are palindromes: they are sequences of digits which read the same backward as forward (for example: 1374731).
The black dots represent a 1:2 ratio between the two cells they connect. All possible black dots are given.
The white dots represent a difference of exactly 1 between two cells they connect. NOT all possible white dots are given.
The puzzle is also available online.
Solution code: Row 9 and Column 9

Bad, bad brain, do NOT assume that 1 star will not require attention and care. Complacency will soon raise it’s ugly head and you will have to restart the puzzle, several times. Many thanks for feeding me the humble pie. Bad brain :)

I really enjoyed the puzzle. At the end, I thought I've made a mistake because I thought I had a deadly pattern, but I got it. Thanks!
