- New puzzle selects another included puzzle.
Controls
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Read a button’s label before selecting it. Look at the feedback after the action.
A useful example
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Apply the same reasoning to the position in your own round. Read the matching step again.
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.
