Free printable number search puzzles

Number Search Puzzle Printable Pack Maker

Choose the numbers, difficulty and how many puzzles, then print a number search puzzle printable pack with answer keys at the end.

Every number search puzzle printable here is made fresh by a free generator in your web browser: number find puzzles with a grid of digits and a list of numbers to circle. Choose your number set and settings, and it makes a pack of 1 to 20 puzzles, one per page, with answer keys at the end. It is free, needs no sign-up, and nothing you make is uploaded or sent to a server.

Use it for a maths review, a classroom set, a quiet activity for adults, or a large print puzzle for older eyes or young children. You can also print a printable number search puzzle for a family game night or a long car journey. Pick Letter or A4 paper, then print the pack or save it as a PDF.

How to print number search puzzles

  1. Open the ‘Numbers’ menu and choose a number set, such as Random, Prime numbers, Square numbers or Years (1900-2099).
  2. If the set has them, set ‘Digits per number’ (for example 5 digits for a five-digit number find) and ‘Multiples of’ (2 to 12, 15, 20 or 25).
  3. Choose a ‘Difficulty’: Easy, Medium or Hard.
  4. Set a ‘Grid size’ from 8 to 20. If you leave it alone, the grid follows the difficulty: Easy 12x12, Medium 14x14, Hard 16x16.
  5. Set ‘How many numbers’ from 6 to 30.
  6. Set ‘Number of puzzles’ from 1 to 20. The default is 4.
  7. Tick ‘Large print’ if you want bigger, bolder digits.
  8. Choose ‘Paper size’: Letter or A4.
  9. Leave ‘Include answer keys’ on, or untick it to print puzzle pages only.
  10. Click ‘Generate puzzles’ and check each card. ‘Show answers’ reveals the answers, and ‘Play online’ opens the same puzzle on the single-puzzle page.
  11. Click ‘Print’. To make a PDF instead, choose ‘Save as PDF’ in the print window.

Changing a setting does not change the cards until you click ‘Generate puzzles’ again, so you can adjust several settings first. Each printed puzzle page has a title, Name and Date lines, the grid and a ‘Find these:’ list with a small checkbox beside each number.

‘Copy link’ saves your settings and a seed. Open the link later, or bookmark it, and the same pack prints again.

Which numbers can a printable number search use?

The ‘Numbers’ menu decides what is hidden. Random numbers come in mixed lengths of 3 to 7 digits (the default) or one fixed length of 3 to 8 digits. The maths sets are prime numbers (3 or 4 digits, such as 101 or 997), multiples of a number, square numbers, cube numbers, triangular numbers, Fibonacci numbers from 144 up to 9,227,465 and powers of 2 from 128 up to 8,388,608. Years (1900-2099) and phone-style numbers like 555-0123 suit adults. A maths set turns the puzzle into a review as well: a square-number search makes children spot 144, 169 and 196. Some sets are small (there are only 17 powers of 2 between 128 and 8,388,608), so the page tells you when a puzzle has fewer numbers than you asked for.

Which settings make hard number search puzzles for adults?

Set Difficulty to Hard, use a 20x20 grid and choose up to 30 numbers. Hard puzzles let answers run in all eight directions, including backwards, and answers may cross each other.

Longer numbers, such as 7-digit numbers, look alike and are harder to tell apart. Phone-style numbers and years from 1900 to 2099 also suit adults. A ready-made Hard 20x20 pack for adults uses these settings.

Is there a large print version?

Yes. Tick ‘Large print’ to get bigger, bolder digits. Large print grids go up to 12x12, with 6 to 12 numbers per puzzle, and the default is 10x10. This suits older eyes and young children. You can also open the large print pack directly.

How do you solve a number search puzzle?

Scan the grid for the first digit of a hidden number, then check its neighbours for the second digit. Start with the longest numbers, and with numbers that contain a rare pair of digits or a repeated digit, such as 881313. Cross off each number on the list as soon as you find it.

Difficulty sets the directions. On Easy, answers run left to right or top to bottom only, and they never overlap. Medium adds the two diagonals that go right (↘ ↗). Hard adds all four backward directions (← ↑ ↖ ↙). On Hard, a number that reads right to left looks reversed, so 5507 appears as 7055.

Each hidden answer appears in the grid exactly once in its allowed directions, so you will not find a second copy elsewhere. A shorter number inside a longer one, such as 123 inside 51234, counts only where it was placed on its own.

Frequently asked questions

Are these number search puzzles free to print?

Yes. The tool is free, needs no sign-up and runs in your browser. Click ‘Print’, or choose ‘Save as PDF’ in the print window to keep a copy.

Do the printables come with answer keys?

Yes. ‘Include answer keys’ is on by default. The answer pages come after the puzzle pages, with four small answer grids per page, or one large grid if your pack has a single puzzle.

Can I play one of the printed puzzles online?

Yes. Every card has a ‘Play online’ link that opens exactly the same puzzle on the number search puzzle page, where you click the first and last digit of each number and a timer runs.

Can I use my own numbers in a printable pack?

Yes. Choose ‘My own numbers’ in the ‘Numbers’ menu and paste your list, such as phone numbers or dates for a quiz. Every puzzle in the pack then hides the same numbers in a different arrangement, which suits a class where each child gets a different sheet.

Can I print the same pack again?

Yes. Click ‘Copy link’ or bookmark the page. The link holds your settings and seed, so it prints the identical pack again, which is useful for a weekly classroom set.

Can I print on Letter or A4 paper?

Yes. Choose Letter (8.5 x 11 in) or A4 under ‘Paper size’ before you click ‘Print’; the page margins and grid size fit the paper you pick, and the choice is remembered in this browser.
