Step by step

Controls
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. Use one clear input at a time.
A useful example
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.
Watch out for this
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Compare the situation with the worked example. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
