A practical guide to Samurai Sudoku

One thing to notice as you play

Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Make the next step deliberately.

What the game asks you to do

Complete five overlapping Sudoku boards. Every shared cell must satisfy both boards that use it. Read that aim before choosing your first action. Start with a deliberate move.

A walkthrough of the rules

  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. Make sure you are interacting with the game rather than the surrounding page.

Put the rules into context

One value entered in an overlap serves two boards, so check the corresponding rows, columns and boxes of both. Your next round may have a different position, so inspect it before acting. Choose a deliberate next step.

A useful caution

A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. A different version of the game may use a different rule. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
