A careful first round
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Make the next step deliberately.
Your goal
Solve the Sudoku while each outside clue gives the sum strictly between 1 and 9 in that row or column. An attractive position is not enough unless the goal is met. Follow this game’s rules rather than another version’s.
Step by step
- 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.
Controls
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. A careful first action helps you become familiar with the layout. Use the visible help when you are unsure of the next input.
A useful example
If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Use the example as a guide rather than a substitute for reading your board. Check the stated objective.
Watch out for this
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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
