Choosing and moving on screen
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. A new-round button replaces the current round.
An example before you play
A two-cell cage labelled 3 holds 1 and 2; a one-cell cage fixes its own value. Apply the same reasoning to the position in your own round. Take a moment to compare.
A common point of confusion
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Compare the situation with the worked example. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
