Something to practise
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Refer to the controls when needed.
The goal to keep in mind
Solve the Sudoku while each outside clue gives the sum strictly between 1 and 9 in that row or column. Use the instructions to see which actions move you towards it. Follow this game’s rules rather than another version’s.
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.
How your actions work
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. A new-round button replaces the current round.
An example to follow
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.
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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
