Practice with a purpose

Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Use the example to check your reasoning.

The goal to keep in mind

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. 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.

Making selections and moves

Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. On a smaller screen, keep the active part of the board within view. A new-round button replaces the current round.

Put the rules into context

If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Your next round may have a different position, so inspect it before acting. Read the matching step again.

A common point of confusion

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. 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.
