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. Keep the playing area visible while using these controls. Contact us with the game and device if a control does not respond.
One way to understand the rules
If the values strictly between 1 and 9 are 2, 4 and 7, the sandwich clue is 13. Apply the same reasoning to the position in your own round. Verify the rule before continuing.
Keep this in mind
A full board must obey every extra rule. Reveal supplies assistance; it is not an earned deduction. Take a moment to reassess the position before continuing. Read one step at a time and try it on the playing area. Match the instruction to the control you use.
