Frequently asked questions
Is the number search maker free?+
Yes. Every number search is free to generate, play, print and download as a PDF — no account or signup required.
How is a number search different from a word search?+
It works exactly like a word search, but the grid is filled with digits (0–9) instead of letters, and you hunt for hidden numbers instead of words. It's a fun way to build number recognition.
Can I use my own numbers?+
Yes. Type or paste any list of numbers and the generator hides them in the grid — great for times tables, primes, dates or any math practice.
Can I make it harder or easier?+
Yes. Switch the difficulty between Easy (across and down only), Medium (adds diagonals) and Hard (adds backwards numbers).
How do I print the number search?+
