The introduction walks you through three key solving techniques with fully worked examples: Naked and Hidden Singles — the essential foundation, shown step by step Doubles (Naked Pairs) — how spotting a shared pair of candidates unlocks cells that seemed impossible Interactions (Pointing Pairs) — when a digit in one box is confined to one row or column, it eliminates that digit elsewhere These three techniques are enough to solve every puzzle here.
