Bring this focus to a round
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.

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. Read a button’s label before selecting it. Read the example below alongside these instructions.
An example to follow
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Your next round may have a different position, so inspect it before acting. Read the matching step again.
Avoid this misunderstanding
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. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
