One thing to notice as you play
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. Refer to the controls when needed.
The purpose of your moves
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. Check the rules when you are unsure.
From the start of a round
- 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 your actions work
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. Avoid pressing the same control repeatedly while a move is being processed.
See how the rules apply
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. Choose a deliberate next step.
Pay attention to this rule
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Take a moment to reassess the position before continuing. After a move, check what changed. Decide which rule explains the new state before acting again.
