A hidden message

Your own message
Type a name, a birthday wish or a class motto — the grid grows to fit it, and the code key is printed under the grid.
Every number exactly once
Each number can be found in only one place, also when numbers run diagonally or backwards — no arguing over the answer key.
For kids and adults

Making a number search book
Free number search generator FAQ
What is a number search puzzle?
A number search prints a grid of digits and a list of numbers. The solver finds each number in the grid — across, down, diagonally or backwards — and circles it, like a word search with digits.
Is this number search generator really free?
Yes. No account, no credit card and no watermark across the puzzles — just a small source line at the bottom of each page.
How does the hidden message work?
When every number is crossed out, some digits stay free. Read row by row in pairs, they spell the message: 01 = A, 02 = B … 26 = Z. The key and the answer boxes are printed under the grid.
Can I write my own message?
Yes. Choose My own message and type a word or a short phrase. Letters A–Z are used (accents are dropped), and the grid is made bigger when a long message needs more room.
Can I print the puzzles for my class or family?
Yes. The free PDFs are for personal and classroom use: print as many copies as you like.
Can I sell these puzzles or publish them on Amazon KDP?
Not the free ones — they are for personal and classroom use only. For books you sell, create a number search book in Wisdom Effect: books generated on paid plans and with credit packs come with a full commercial license.
Do the puzzles come with answers?
Yes. An answer page with every number marked and the hidden message filled in is added by default; switch it off if you only want the puzzles.
