About this book
100+ puzzles for adults, one puzzle per page in big, clear print, with plain-language instructions, solving tips and a complete answer key in the back. Built for travel, waiting rooms, quiet evenings and gifts.
A puzzle book earns its place by being fair. Every grid here is generated and then verified - one solution, no ambiguity, no page that only works if you guess. What is left is the good part: a clean grid, a sharp pencil, and half an hour that belongs to you.
Large 8 x 10 inch paperback with one puzzle per page, printed on bright white paper with generous margins and no bleed-through. Lies flat enough to solve one-handed. Complete answer key in the back.
What's inside
- Three puzzle types in one book: 30+ sudoku, 30+ crosswords and 30+ word searches, mixed so no one type wears out its welcome
- A technique refresher per type for anyone coming back to a puzzle they have not touched in years
- A steady hard band across all three types
- Every sudoku has one solution, every crossword is solvable from the clues, and every word search hides each word exactly once
- One puzzle per page with room to write
- Complete answer key in the back, organised by type
