Take a closer look while playing
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Make the next step deliberately.

Fill rows, columns and boxes with 1–9 once. Cage digits cannot repeat and must add to their clue. Read that aim before choosing your first action. Notice how the game responds to your input.
The steps to 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.
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. Avoid pressing the same control repeatedly while a move is being processed.
A useful 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. Take a moment to compare.
One detail worth checking
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Compare the situation with the worked example. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
