History of Samurai Sudoku

Rules of Samurai Sudoku
Samurai Sudoku follows the traditional Sudoku rules, with a few unique twists. Here are the basic rules:
- The puzzle consists of a 9×9 grid, divided into nine 3×3 sub-grids or "regions."
- The goal is to fill in the missing numbers, making sure each row, column, and region contains the numbers 1-9 without repeating any number.
- Each region has a unique twist: some regions have already been filled with numbers. These numbers cannot be changed and must be respected.
- The remaining blank cells can be filled with numbers 1-9, following the traditional Sudoku rules.
