Inside the book
Four worked examples, then practice
Pointing, claiming, naked pair, and hidden pair examples show exact candidate changes before the puzzle section. The five-step loop starts with singles, then checks locked candidates and pairs before updating candidates and repeating.
Practice grids measure at least 4 inches per side; the answer key is compact. This is not a large-print edition throughout.
