Read before your next round of Sandwich Sudoku
Choose a round of Sandwich Sudoku and settle into its rules. Solve the Sudoku while each outside clue gives the sum strictly between 1 and 9 in that row or column.

The challenge in front of you
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. Return to the instructions when a step is unclear.
How to proceed
- Select an editable cell.
- Enter a value using the keypad or keyboard; Notes stores candidates.
- Read the region, cage, arrow or outside clues alongside the normal constraints.
- Check entries verifies the completed board; Undo reverses your last input.
- New puzzle selects another included puzzle.
Keyboard and screen controls
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. Check any mode label before starting.
Follow the example
If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Focus on why the action is allowed, not only its outcome. Keep the controls nearby.
A common point of confusion
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Compare the situation with the worked example. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
