Samurai Sudoku is a larger Sudoku variant made from five linked 9x9 grids. Four corner grids share 3x3 overlap zones with the center grid, so every shared cell must satisfy two boards at once. The result is a free Samurai Sudoku puzzle that feels deeper than classic Sudoku without changing the core row, column, and box rules.
Read the rulesTo play Samurai Sudoku online, choose today's challenge or another difficulty, select a cell, enter a digit, and use pencil mode when a candidate is uncertain. The workspace saves progress locally, keeps the daily Samurai Sudoku stable, and can highlight conflicts while you solve.
Play the boardOverlap zones carry two sets of constraints. A confirmed digit inside one shared 3x3 area can simplify rows, columns, and boxes on both connected grids, which makes it a better first scan than a random corner. Start with the densest overlap, then follow the result through the center grid.
Study tacticsA printable Samurai Sudoku sheet is useful when you want pencil notes, paper focus, or offline practice. Print the daily Samurai Sudoku or any saved puzzle as a clean sheet with only the original givens, then return online later if you want conflict checking and recovery.
Print today's puzzleClassic Sudoku uses one 9x9 grid. Samurai Sudoku keeps the same logic rules but links five grids, so the challenge is about moving information through shared cells and restarting stalled boards. If classic Sudoku feels automatic, Samurai adds scale and planning without asking you to learn a new ruleset.
