Word Search Generator

How do I make a word search puzzle from my own words?

Open AnyTool Word Search Generator, type a title, paste your word list (one word per line), pick a difficulty — Easy hides words across and down, Medium adds backwards, Hard adds diagonals and their reverses — and choose a grid size or let it auto-grow. Tap Generate and a grid is built in your browser: each word is laid along an allowed direction at a random spot, words cross only where they share a letter, and empty cells fill with random letters. Click words to cross them off, toggle Show answers to reveal them all, then Print a clean puzzle and a separate answer key. Your words never leave the browser.

What is

A word search generator hides a list of words inside a square grid of letters, each word laid along a straight line in one of up to eight directions (horizontal, vertical and diagonal, forwards or backwards). Words may cross where they share the same letter, and every remaining cell is filled with a random letter so the hidden words blend in. The solver finds and marks each listed word; an answer key shows where every word is placed.

Frequently Asked Questions

Difficulty is set by which directions a word may be placed along. Easy uses only left-to-right and top-to-bottom, so words are quick to spot. Medium also allows the backwards versions (right-to-left and bottom-to-top). Hard adds the two diagonals and their reverses, for the full set of eight directions. Backwards and diagonal placements are the hardest for most solvers to find, so adding them raises the challenge. Horizontal and vertical are always allowed; the toggles add the rest.

Yes. Easy hides words across and down only, Medium adds backwards, and Hard adds diagonals and their reverses — more directions means a harder puzzle.

The grid is never smaller than your longest word. If a word still cannot be placed — for example the grid is small and crowded — Auto-grow (on by default) enlarges the grid one step at a time, up to 30×30, and retries until everything fits. If you turn Auto-grow off, words that cannot be placed at the chosen size are dropped and listed in a warning so you know exactly which ones, and you can increase the size or shorten the list. Words are allowed to cross where they share the same letter, which lets more of them pack into the grid.

With Auto-grow on, the grid enlarges (up to 30×30) until every word fits; otherwise any word that cannot fit is dropped and clearly flagged.

On screen, Show answers highlights every placed word in the grid, and you can click words in the list to cross them off and highlight them one at a time as you solve. For paper, Print opens a crisp, ad-free puzzle with the word list underneath, and Print + key adds a second page with every word highlighted as the answer key — ideal for teachers grading worksheets. For clean square cells, print at 100% / actual size rather than fit-to-page.

Both. Show answers highlights every hidden word on screen, and Print opens a clean puzzle plus a separate answer-key page.

AnyTool Word Search Generator is completely free with no sign-up. Your title, word list and the finished grid are processed locally using your browser, with the Web Crypto API for randomness (never Math.random), so every Generate truly reshuffles the layout. Nothing is uploaded, logged or saved — closing the tab discards everything — which makes it a safe choice for teachers and parents who would rather a vocabulary list never left the classroom. There is no tracking, and the page works offline after its first load.

Yes. It is free, needs no account, and runs entirely in your browser — your words and the puzzle are never uploaded, logged or stored.

Detailed Explanation

Methodology

How AnyTool Places Words and Fills the Grid

Generation runs entirely in the browser. The raw word list is first sanitized — uppercased, stripped to A–Z only, words under two letters dropped, and duplicates removed in first-seen order. A working grid size is chosen that is never smaller than the longest word (and at least 5×5, at most 30×30). Words are placed longest-first, since long words are the hardest to fit before the grid fills. For each word the engine builds every valid (start cell × allowed direction) option, shuffles them with the Web Crypto API (crypto.getRandomValues via rejection sampling, never Math.random), and walks them until one fits: a placement fits when it stays in bounds and every cell it covers is either empty or already holds the matching letter, so words may legally cross where they share a letter. Because the start options are exhaustive, a word is reported unplaceable only when it genuinely cannot fit the current grid. With Auto-grow on, the grid enlarges one step at a time until every word fits or it reaches 30×30. Finally, each still-empty cell is filled with a crypto-random letter A–Z so the hidden words blend in.

Words sanitized: uppercased, letters-only, min 2 letters, de-duplicated
Placed longest-first; start cells × directions shuffled with the Web Crypto API
A word fits when in-bounds and overlaps only on matching letters (legal crossings)
Unplaceable words are flagged; Auto-grow enlarges the grid (up to 30×30) to fit them
Empty cells filled with crypto-random letters — all client-side, nothing uploaded

How It Works

Directions and Difficulty Levels

The difficulty of a word search is governed by the set of directions words may hide along, out of eight possible: horizontal (east/west), vertical (south/north) and the two diagonals (south-east/north-west and north-east/south-west), each available forwards or as its reverse. AnyTool always allows horizontal-forward (left-to-right) and vertical-forward (top-to-bottom). Easy uses only those two, so words read normally and are quick to find. Medium adds the backwards reverse of each enabled axis (right-to-left and bottom-to-top). Hard additionally allows the two diagonal axes and their reverses, for the full eight directions. As consistently reported by puzzle makers, backwards and diagonal placements are the hardest for solvers to spot, so enabling more directions raises difficulty; larger grids with more filler letters also take longer to scan.

Up to eight directions: E/W, S/N, SE/NW, NE/SW (forwards and reverse)
Horizontal-forward and vertical-forward are always enabled
Easy = → ↓ only · Medium = + backwards · Hard = + diagonals and their reverses
Backwards and diagonal words are the toughest to find — they raise difficulty
Bigger grids with more filler letters take longer to scan

Use Cases

Answer Key, Solving In-Browser and Printing

On screen the puzzle is interactive: Show answers highlights every placed word in the grid at once, and clicking a word in the list crosses it off and highlights just that word, so a solver can mark progress as they find each one. The word list under the grid lists only words that were actually placed, alphabetized for easy scanning, with a found-count. For paper use, Print opens a clean, ad-free window containing the titled puzzle and the word list, and Print + key appends a separate answer-key page where every word is highlighted in place — handy for teachers grading worksheets. Because everything is rendered locally, printing uploads nothing; for crisp, square letter cells you should print at 100% / actual size rather than fit-to-page. The title, word list and grid never leave the browser, making the tool a privacy-safe option for classroom vocabulary lists.

AnyTool. "Word Search Generator (browser-based generator for printable word search puzzles from your own word list, with selectable directions and difficulty, auto-grow grid sizing, an answer key, in-browser solving and clean printing — 100% client-side)." AnyTool, January 1, 2026. https://www.anytool.tech/word-search-generator

A privacy-first, 100% client-side word search generator that hides a custom word list inside a square grid of letters. The raw list is sanitized (uppercased, stripped to A–Z, words under two letters dropped, duplicates removed in first-seen order), and a working grid size is chosen that is never smaller than the longest word (at least 5×5, at most 30×30). Words are placed longest-first; for each word the engine enumerates every valid (start cell × allowed direction) option, shuffles them with the Web Crypto API (crypto.getRandomValues via rejection sampling, never Math.random), and uses the first that fits — fitting when the word stays in bounds and overlaps existing letters only where they match, so words may legally cross on shared letters. Difficulty is set by the allowed directions out of eight (E/W, S/N, SE/NW, NE/SW): Easy uses left-to-right and top-to-bottom only, Medium adds the backwards reverse of each, and Hard adds the diagonals and their reverses; horizontal-forward and vertical-forward are always enabled. The grid size can be chosen or, with Auto-grow on, enlarged one step at a time (up to 30×30) until every word fits; any word that still cannot be placed is dropped and flagged so the user can grow the grid or shorten the list. Remaining cells are filled with crypto-random letters A–Z. On screen, Show answers highlights every placed word, clicking a word crosses it off and highlights it individually, and the word list under the grid shows only placed words, alphabetized, with a found-count. Print opens a clean, ad-free puzzle with the titled grid and word list, and Print + key adds a separate answer-key page with every word highlighted in place. All generation, solving and printing run locally — the title, word list and grid are never uploaded, logged or stored, and the tool works offline once cached, making it safe for classroom vocabulary lists. Honestly, words overlapping where they share a letter is normal and intended; a word is dropped only when it genuinely cannot fit, in which case increasing the grid size (or keeping Auto-grow on) resolves it; and for crisp, square printed cells you should print at 100% / actual size rather than fit-to-page.
