Palindrome Sudoku
A fascinating Sudoku variation where marked lines form palindrome strings
Palindrome Sudoku is a fascinating and interesting Sudoku variation where lines are drawn in the Sudoku grid, and the digits on each line form a palindrome string. This means that if you start from each end of the line and move toward the center, the digits on both ends will be the same. A good way to solve Palindrome Sudoku puzzles is to start marking the ends of each palindrome line with symbols (e.g., a, b, c) and then remove the possibilities of these digits from other rows, columns, or outlined regions by combining these symbols. This collection includes standard Palindrome Sudoku puzzles, Consecutive Pairs-Palindrome Hybrid Sudoku, and Palindrome-Extra Region Sudoku. This page contains links to all Palindrome Sudoku puzzles and their variations published on this website.
Rules of Palindrome Sudoku
Place a digit from 1 to 9 into each of the empty cells so that each digit appears exactly once in each row, column, and 3x3 outlined box. Additionally, the digits in the squares with the line form palindromes, meaning they read the same from both directions.
