Thermo Palindromes
(Published on 14. January 2021, 01:00 by Lisztes)
RULES:
Normal and Diagonal Sudoku rules apply. Each row, column, 3x3 box and diagonal 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). Each half of the palindromes also act like thermometers: digits increase from the ends (for example: 14641 is valid, but 53835 is invalid, because 5 is greater than 3).
Inequality signs between two cells show which one contains the lower/higher digit.
The puzzle is also available online.
Solution code: Row 1 and Row 9
