What's inside
- 400+ sudoku puzzles, weighted towards the full-size 9×9 grid
- 234 classic 9×9 puzzles — the same grid adults solve
- 108 6×6 puzzles and 60 4×4 puzzles for warming up or building speed
- Easy, medium and hard runs within every grid size, so the book keeps getting harder
- Full answer key at the back, numbered to match
- Large 8.5 × 11 pages, 109 pages in total
This book is built for a child who is ready for the full 9×9 grid — more than half its puzzles are full size, and each grid size runs from its easy section to its hard one. The smaller grids are still there, but as a warm-up rather than the main event. It is the edition to buy when a child has finished a beginner sudoku book and found it too easy.
What to expect
