Printable Samurai Sudoku
A Samurai Sudoku is five 9×9 Sudoku grids on one sheet. The middle grid shares a 3×3 corner box with each of the other four, so a number you find in a shared box counts in two grids at once. Print one sheet or ten; each puzzle's answer comes on the page after it.
Quick answer
Every puzzle here has exactly one answer and can be solved without guessing. Easy puzzles need only naked singles: a square where just one number is left. Medium puzzles also need hidden singles: a number that has only one place left in a row, column or box.
