Take a closer look while playing
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. Make the next step deliberately.
Understand the aim
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. Return to the instructions when a step is unclear.
How to proceed
- 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.
Input guidance
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.
Learn from a sample situation
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Compare this with the rule that governs the move. Keep the controls nearby.
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. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
