Making selections and moves
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Use the control method described here for this activity. Look at the feedback after the action.
An example to follow
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. Consider the next action carefully.
Pay attention to this rule
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Read the feedback to see why an action did not have the expected result. Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board.
