Follow the steps for Sandwich Sudoku

Something to practise

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. Use the example to check your reasoning.

What counts as success

Solve the Sudoku while each outside clue gives the sum strictly between 1 and 9 in that row or column. Keep that objective in view throughout the round. Take a moment to understand the current position.

Start here and follow along

  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.

Using the playing area

Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Use the control method described here for this activity. Contact us with the game and device if a control does not respond.

Put the rules into context

If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Apply the same reasoning to the position in your own round. Take a moment to compare.

Avoid this misunderstanding

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. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
