What is Samurai Sudoku?
Samurai Sudoku is an epic variant featuring five overlapping 9×9 grids arranged in a cross pattern. The center grid shares its corner 3×3 boxes with the four surrounding grids, creating 369 unique cells to solve.
Every cell must satisfy the rules of each grid it belongs to — rows, columns, and 3×3 boxes. Overlapping cells are constrained by both grids, making Samurai the ultimate Sudoku challenge.
