A small practice goal
Before your first action, say what you are trying to achieve. Then compare the result with the goal. Notice the feedback after each input.
Your objective
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. Follow this game’s rules rather than another version’s.
The order of 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.
Controls
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. 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. Compare this with the rule that governs the move. Look for the relevant detail.
A useful caution
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. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
