A 4×4 grid uses only the numbers 1 to 4 in sixteen squares, so the rule can be learned on a puzzle that is quick to finish. This book starts there, with 120 of them, and only then moves on to 6×6 and full 9×9 grids.
What to expect
✓
No reading required
The rule is visual: no number twice in a row, column or box. There is no arithmetic anywhere in sudoku.
✓
Starts small
The book opens on its 120 4×4 grids, the smallest size, before any 6×6 or 9×9 puzzle.
✓
Self-checking
The answer key at the back lets a child check their own work without an adult marking it.
