Try a deliberate move
After a move, check what changed. Decide which rule explains the new state before acting again. Notice the feedback after each input.

Controls
Click or tap cells and the digit pad. Use Notes, Undo and Reveal selected. Large boards scroll inside the game. Use the control method described here for this activity. Avoid pressing the same control repeatedly while a move is being processed.
A useful example
The coloured region, not a conventional 3×3 box, defines the third no-repeat constraint. Compare this with the rule that governs the move. Keep the game’s format in mind.
Watch out for this
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. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
