Everything a classic number search book needs
Pure number hunting
A grid of digits and a list of numbers to cross out, sorted by length. No code key, no message boxes: solvers know what to do at a glance.
Every number found once
Each number can be read in exactly one place, and no number hides inside another: no puzzle with two answers, no "I found it twice".
Grids up to 20×20
Grids from 8×8 to 20×20, numbers of 3 to 10 digits and up to 30 numbers per puzzle, running straight, with diagonals or in all 8 directions, also backwards.
Kids & Large Print editions
Short numbers that run only right and down for children; big digits and 1 puzzle per page for seniors; holiday books for Christmas, Halloween and more.
Unique, reproducible books
Every book gets its own book code: the same code prints the same puzzles again, a new one brand-new puzzles. Nothing is repeated from a shared bank.
Print-ready for KDP
5×8, 5.5×8.5, 6×9, 6.14×9.21, 7×10, 8×10, 8.5×11, 8.27×11.69, 8.5×8.5 trim sizes with automatic gutter and safe margins, answer keys, table of contents and PDF, PNG or SVG export.

Number search book guides
Classic number search book FAQ
What is a classic number search puzzle?
A number search is a word search with digits: a grid full of numbers and a list of numbers to find, running across, down, diagonally or backwards. The classic version is only the hunt — find every number and the puzzle is solved.
How is it different from the hidden message number search?
The Number Search book type adds a second step: the digits left over spell a phrase with a code key (A=01 … Z=26). Classic Number Search leaves it out, so you choose freely how many numbers fill each grid, and short 3-digit numbers work in every direction.
Can I create classic number search books for Amazon KDP?
Yes. Books generated on paid plans and with credit packs include a full commercial license, KDP trim sizes with safe margins and answer keys, and you keep 100% of your royalties.
Which plans include classic number search books?
Every plan: Starter, Pro and Publisher, and the free trial, with every option — grids up to 20×20, all 8 directions and the Kids and Senior editions.
How many credits does a classic number search book cost?
One credit per puzzle (one grid up to 20×20). A 30-puzzle book costs 30 credits, and re-exporting the same book with design changes is free.
Can I combine it with other puzzles?
Yes. Mixed books can contain Classic Number Search, Sudoku, Word Search, Maze, Word Scramble, Missing Vowels, Fill-In, Missing Vowel Word Search, Crossword, Codewords, Cryptogram, Anagram, Mine Finder, Hidden Message Word Search, Number Search, Wordoku, Nonogram, Color Nonogram, Zebra Nonogram and Triangle Nonogram chapters in any order. Every plan makes mixed books from the puzzle types it includes: Starter mixes Sudoku, Word Search, Maze, Word Scramble, Missing Vowels, Fill-In, Classic Number Search and Missing Vowel Word Search; Pro mixes 17 types (all but Color Nonogram, Zebra Nonogram and Triangle Nonogram); Publisher mixes all 20 types.
Can I make classic number search books in German, French, Spanish, Japanese or other languages?
Yes, on the Publisher plan and in the free trial. Pick one of 10 book languages, one for each Amazon marketplace: English (amazon.com, amazon.co.uk, amazon.ca, amazon.com.au, amazon.in), German (amazon.de), French (amazon.fr), Spanish (amazon.es, amazon.com.mx), Italian (amazon.it), Dutch (amazon.nl), Brazilian Portuguese (amazon.com.br), Japanese (amazon.co.jp), Polish (amazon.pl), Swedish (amazon.se). Wisdom Effect then prints the texts it writes into the book in that language: puzzle and solution titles, chapter headings, the table of contents, difficulty labels, the copyright page (10 legal templates), the intro and thank-you pages and the labels on the puzzle pages, seasonal editions included. Numbers need no translation: only the book texts change. Texts you write yourself are not translated, so write them in the book's language. Starter and Pro books are printed in English.
