An example before you play
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Focus on why the action is allowed, not only its outcome. Consider the next action carefully.
Check this before moving on
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Check the rule before repeating the action. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
