Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. A careful first action helps you become familiar with the layout. Look at the feedback after the action.
See the idea in action
If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Use the example as a guide rather than a substitute for reading your board. Take a moment to compare.
Where a round can go wrong
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. 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.
