What's inside
The book opens with a cover and a one-page statement of the rules — two stars in every row, column and outlined region, no two stars touching — then the boards, four to an A4 page, sized for a pencil. The tiers climb as you go: Easy × 4, Medium × 4, Hard × 4, Expert × 4. By the third page you'll know which single-tier book to print next.
Every board is a released daily puzzle, checked by our solver to have exactly one solution reachable by logic alone. If you feel the urge to guess, you've missed a move — and the strategy guide covers the moves these boards ask for.
