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
By eight, most children can handle a full 9×9 grid, and this book is built on that assumption — more than half its puzzles are full size, and the hard 9×9 section is genuinely hard rather than nominally so. 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.
Why parents choose this book
✓
It does not run out
400+ puzzles with a rising difficulty curve, so a child who takes to it is occupied for months.
✓
Real difficulty, not padded
The hard 9×9 puzzles need candidate marking. A twelve-year-old will not clear them on autopilot.
✓
Entirely independent
Clear instructions and an answer key mean no adult has to be involved at any point.
