A focus for your next round
Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round. Keep the objective visible.
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. An attractive position is not enough unless the goal is met. Try to explain the aim in your own words.
The steps to play
- 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.
The controls to know
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. Use one clear input at a time.
Learn from a sample situation
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. Consider the next action carefully.
Keep this in mind
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Take a moment to reassess the position before continuing. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
