What counts as success
Fill rows, columns and boxes with 1–9 once. Cage digits cannot repeat and must add to their clue. An attractive position is not enough unless the goal is met. Start with a deliberate move.
Step by step
- 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.
How to interact with the game
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Use the control method described here for this activity. Avoid pressing the same control repeatedly while a move is being processed.
A closer look at one example
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Use the example as a guide rather than a substitute for reading your board. Consider the next action carefully.
Notice this detail
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Compare the situation with the worked example. 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.
