Controls
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. Use the visible help when you are unsure of the next input.
Work through an example
On one puzzle in this collection, row 1, column 1 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. Read the matching step again.
A mistake to avoid
Notes are reminders, not final entries. A full board only counts as complete when it satisfies every rule. A different version of the game may use a different rule. After a move, check what changed. Decide which rule explains the new state before acting again.
