Read before acting
Read one step at a time and try it on the playing area. Match the instruction to the control you use. Keep the objective visible.
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. Return to the instructions when a step is unclear.
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. Keep the playing area visible while using these controls. Return to the rules if the result is unexpected.
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. Read the matching step again.
Watch out for this
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
