How to Play Samurai Sudoku: Five Grids and Shared-Cell Logic

Samurai Sudoku combines five overlapping 9×9 Sudoku grids. Four outer grids share a 3×3 box with the central grid, so every shared cell must satisfy two sets of row, column, and box constraints.

This guide explains the layout, overlap rules, and a practical way to pass deductions between the five grids.

1. What Is Samurai Sudoku?

Sudoku samurai is a puzzle made up of five overlapping 9×9 Sudoku grids. One grid sits in the center, while four others overlap it at the corners.

Each overlapping section must satisfy the rules of both grids, making samurai sudoku significantly harder than standard Sudoku.

2. Samurai Sudoku Rules Explained

Although the layout is more complex, the rules of samurai sudoku are familiar:

  1. Each row must contain numbers 1–9 without repetition.
  2. Each column must contain numbers 1–9 without repetition.
  3. Each 3×3 box must contain numbers 1–9 without repetition.
  4. Overlapping cells must satisfy both connected grids.

These simple rules create deep logic challenges across the entire puzzle.

3. How to Play Samurai Sudoku Step by Step

Start with the Central Grid

The middle grid connects all four outer grids. Solving parts of it early gives you valuable information for the entire puzzle.

Solve One Grid at a Time

Focus on completing individual grids while paying attention to overlapping areas. Progress in one grid often unlocks progress in others.

Use Elimination Carefully

Because grids overlap, eliminating a number in one place can affect several regions. Careful logic is essential.
