How to Play Palindrome Sudoku

  1. Standard Sudoku rules apply.
  2. Highlighted lines are palindromes — digits read the same from both ends.
  3. The first cell equals the last, the second equals the second-to-last, etc.
💡 Pro Tip
On an odd-length palindrome, the center digit is unconstrained by the palindrome rule. Focus on the mirrored pairs first.

Frequently Asked Questions

Do all palindrome lines need to be the same length?

No — palindromes can be any length. Longer lines just have more mirrored pairs to deduce.

Does the center cell of an odd-length palindrome have a constraint?

Not from the palindrome rule — it mirrors itself. It still has to satisfy standard Sudoku constraints though.
