What counts as success
Fill rows, columns and boxes with 1–9 once. Cage digits cannot repeat and must add to their clue. The feedback beside the game helps you follow the round. Check the rules when you are unsure.
How a round unfolds
- Select an editable cell.

- 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.
The controls to know
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. Use the visible help when you are unsure of the next input.
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. Keep the game’s format in mind.
A mistake to avoid
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. A different version of the game may use a different rule. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
