Tap or click a cell and use the number pad. Keyboard: arrows select cells; digits (and A–G on 16×16) enter values; Backspace erases. A careful first action helps you become familiar with the layout. Check any mode label before starting.
Learn from a sample situation
On one puzzle in this collection, row 1, column 3 has 4 in its solution. Read the clues on your current board before using that value; another puzzle can need a different entry. Use the example as a guide rather than a substitute for reading your board. Check the stated objective.
Watch out for this
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. Take a moment to reassess the position before continuing. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
