Your guide to Samurai Sudoku

Bring your attention to one round of Samurai Sudoku. Complete five overlapping Sudoku boards. Every shared cell must satisfy both boards that use it. Look at what changes after your first action. Make your first input carefully and watch the result. Choose a clear next step rather than rushing through the instructions.

This collection contains 4 puzzles. Progress is saved in this browser. The same puzzle can appear again; the collection is not labelled with calibrated difficulty levels.

One thing to notice as you play

Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Make the next step deliberately.

What you need to achieve

Complete five overlapping Sudoku boards. Every shared cell must satisfy both boards that use it. Use the instructions to see which actions move you towards it. Take a moment to understand the current position.

From the start of a round

  1. Select an editable cell.
  2. Enter a value using the keypad or keyboard; Notes stores candidates.
  3. Read the region, cage, arrow or outside clues alongside the normal constraints.
  4. Check entries verifies the completed board; Undo reverses your last input.
  5. New puzzle selects another included puzzle.

Your inputs

Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Read a button’s label before selecting it. Use one clear input at a time.

See how the rules apply

One value entered in an overlap serves two boards, so check the corresponding rows, columns and boxes of both. Use the example as a guide rather than a substitute for reading your board. Notice the change in the playing area.

A useful caution

A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Read the feedback to see why an action did not have the expected result. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
