Solving on paper
Keep candidate notes up to date and examine the most constrained units first. If progress stops, review the notes before looking for pairs or intersections. A difficulty label does not guarantee a particular technique.
Print at a scale that keeps the digits clear and leaves room for notes. Keep the answer image separate until you are ready to check. For multiple puzzles on a page, use the printable generator and select hard difficulty.
