A small practice goal

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.

Aim for this result

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. Notice how the game responds to your input.

How to proceed

  1. Select an editable cell.
  2. Enter a value using the keypad or keyboard; Notes stores candidates.
  3. Read the region, cage, arrow or outside clues alongside the normal constraints.
  4. Check entries verifies the completed board; Undo reverses your last input.
  5. 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. Keep the playing area visible while using these controls. A new-round button replaces the current round.

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. Choose a deliberate next step.

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. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
