Here are three puzzles: a Samurai Sudoku, and two regular Sudokus.
The Samurai Sudoku puzzle is made up of five smaller Sudoku puzzles: one in the center and the other four overlapping the corner grids of the central one. Each of the smaller puzzles has the same rules as a classical Sudoku: each row, column and 3×3 grid must contain all of the digits 1 to 9.
