This sudoku is meant to explore the use of the Anti-palindrome constraint.
Standard sudoku rules apply: each row, column, and box must contain all the digits from 1 to 9.
Digits within cages must sum to the small number in the top left corner of the cage.
The red lines are Anti-palindrome lines: the Nth digit from one end added to the Nth digit from the other end must sum to 10. For example, if the second digit from one end is 3, the second digit from the other end must be 10-3=7.
Lösungscode: Enter the 6th row (R6) as the solution code.

nice puzzle. I agree with asp1310, dot in the middle of palindrome should be standard :)

Putting a dot in the middle of a palindrome line is an innovation more should follow! While I’m sure it speeds up some revelations on some puzzles when you have ignored the middle point for a while and suddenly realise it, that’s not really a massive deduction and SHOULD be given away for free. It saves on needlessly colouring out the line.
