Controls
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. Avoid pressing the same control repeatedly while a move is being processed.
An example before you play
If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Compare this with the rule that governs the move. Verify the rule before continuing.
A mistake to avoid
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
