About this book
100+ sudoku for kids, ages 9-12, one puzzle per page in big, clear print, with plain-language instructions, solving tips and a complete answer key in the back. Built for screen-free afternoons, travel days, classrooms and gifts.
Puzzle books get abandoned for one of two reasons: the first page is too hard, or every page is the same. This one climbs on purpose and changes its subject constantly, so a kid who opens it at the kitchen table is still in it forty minutes later - quiet, off a screen, and genuinely working something out.
Large 8 x 10 inch paperback with one puzzle per page, printed big and clean on bright white paper so pencil, pen and marker all behave. Every puzzle stands alone, and the complete answer key is in the back.
What's inside
- A plain-language teaching page up front that explains the one rule of sudoku with a worked example, so no adult has to teach it
- Solving tips kids can actually use: scan a row, find the only square left, mark the maybes in pencil
- Every grid computer-checked for exactly one solution, so a puzzle never dead-ends and never needs a guess
- A consistent hard band throughout - no surprise spike in the middle of the book
- Room to write in every square, with light pencil-mark space in the corners
- Full answers in the back, laid out so checking one puzzle does not spoil the next
