The objective of a round
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. The example below illustrates a decision.
Making your moves
- 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.
Input guidance
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 one clear input at a time.
One way to understand the rules
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. Read the matching step again.
A useful caution
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Compare the situation with the worked example. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
