MindGrid publishes sudoku in two families. Six books are for adults and older solvers, all on classic 9×9 grids, differing by difficulty and by format. Four are for children, and those differ by how much of the book is spent on small grids before the full-size ones arrive. Every book prints its complete solutions at the back.

Children's sudoku is graded by grid size before it is graded by difficulty. A 4×4 grid uses only the numbers 1 to 4 and is closer to a matching task than a logic problem, which is what makes it workable for a five-year-old. A 6×6 grid introduces rectangular boxes. A 9×9 grid is the puzzle adults solve.
All four books below contain more than one grid size. What actually differs is the balance: the youngest edition opens on 4×4 and spends most of its pages there, while the oldest is more than half full-size 9×9. Treat the ages on the covers as a starting point, not a rule — children arrive at this at their own pace.
Sudoku for Kids 4-6
Around 200 puzzles opening on 4×4 grids, then 6×6 and 9×9 for later. Number grids, not picture puzzles — a child needs to recognise the digits.

One level, or all of them
The easy, medium and hard books hold a single difficulty for 1,008 puzzles, so nothing shifts under you. 1000+ Sudoku Puzzles for Adults spans all six levels at 168 puzzles each instead — better if you do not yet know where you sit.
Print size is a layout decision
Twelve puzzles to a page and two puzzles to a page are the same trim size with very different grids. That ratio, not the words on the cover, is what makes the large print edition readable.
Where you solve matters
The 8.5 × 11 books are table books. The travel edition is 5 × 8 and holds 150 puzzles rather than a thousand — the one you take with you, not the one you work through at home.
For a child, start below their age
A first puzzle a child can actually finish is what buys the patience for the harder ones. If you are between two editions, the younger one is the safer buy: its later sections still contain full 9×9 grids.
Every one of these is in print now. Pick the level from the cards above, or browse the full catalogue on Amazon.
