You know the words are in there, but your eyes keep sliding past them. If you want to know how to solve a word search quickly, scan for the rarest letter in each word, check all eight directions around it, and then sweep the grid row by row for whatever is left.
Why a word search is hard for your eyes
Letters all look alike to your visual system. A red letter among black ones jumps out at once. A T among Ls does not, and you have to look at the letters one by one. In a review of the research, Jeremy Wolfe and Todd Horowitz write that a search for a T among Ls costs roughly 20 to 50 milliseconds for every extra item on display.
A 15×15 grid has 225 letters. At that lab pace, checking every letter once for a single target takes about 5 to 11 seconds, before you even follow a lead. That is why a plan beats staring. Every step below cuts down the number of letters you have to look at.
How to solve a word search: the seven steps at a glance
| Step | What to do | What to watch for |
|---|---|---|
| 1 | Read the word list and pick one word | Start with words that have rare letters |
| 2 | Scan the grid for the word's rarest letter | Q, Z, X, J, K, V and double letters |
| 3 | Check all eight directions from each copy | Diagonals and backwards runs |
| 4 | Sweep rows, then columns, then diagonals | Use a ruler or a finger to keep your place |
| 5 | Read every line backwards too | In hard puzzles about half the words run backwards |
| 6 | Mark each word and cross it off | Words can share letters |
| 7 | Take a break, then use the answer key | Check only the word you are stuck on |
Step 1: Read the word list and choose your first word
Read the whole list once before you look at the grid. Then pick a word with an unusual letter, a Q, Z, X or J, or a double letter. Those words are the easiest to find, and finding a few early keeps you going.
Short words with common letters, such as TEA or ART, are the hardest. Leave them for later, when fewer letters are left to check.
Step 2: Scan for the rarest letter, not the first letter
Most people hunt for the first letter of the word. The better anchor is the rarest letter in it. Peter Norvig's count of letters in Google Books shows E makes up 12.49% of English letters, while Z makes up 0.09%. E is about 140 times as common as Z.
| Letter | Share of English letters | Use it as an anchor? |
|---|---|---|
| E | 12.49% | No, it is everywhere |
| T | 9.28% | No |
| A | 8.04% | No |
| X | 0.23% | Yes |
| J | 0.16% | Yes |
| Q | 0.12% | Yes |
| Z | 0.09% | Yes, the best one |
Our own puzzles show the same effect. Across the 1,470 hard puzzles on Word Search PDF, the first letter of a hidden word appears about 13 times in its grid, on average. The rarest letter of the word appears about 6 times. Scanning for the rare letter gives you fewer than half as many places to check.
Step 3: Check all eight directions from each copy
When you find your anchor letter, check the eight letters around it for the next letter of the word. A word can run left, right, up, down or along any of the four diagonals.
Once the second letter fits, follow that line to the end of the word. If the third letter is wrong, go back to the anchor and try the next direction. Keep a finger on the anchor so you do not lose it.
Step 4: Sweep rows, then columns, then diagonals
When no rare letter helps, switch to a sweep. Read the first row from left to right, then the next, all the way down. Then do the columns from top to bottom. Then the diagonals.
A ruler or a strip of paper under the row keeps your eyes from drifting. On screen, move the page so the row you are reading sits at eye level. Sweep for two or three words at once only when they share a letter, such as two words with a K.
Some puzzles are easier to sweep than others. Easy grids hide words only across and down, so a row and column sweep finds everything. To see which level suits you, the All word searches page lets you filter every puzzle by easy, medium, hard or giant.
Step 5: Read every line backwards too
Backwards words are the main reason people get stuck. Your eyes are trained to read left to right, so a word running right to left hides in plain sight.
Our puzzles show how much this matters as the level rises. Medium puzzles on Word Search PDF have no backwards words, and about 38% of their words run along a diagonal. Across the hard puzzles, about half of the 26,620 hidden words run backwards and about 39% run diagonally.
A simple trick helps here. Spell the word backwards on the edge of the page, then search for that spelling. AMAZON becomes NOZAMA, and the eye catches it more easily.
Step 6: Mark each word and cross it off the list
Circle or highlight each word as soon as you find it, then cross it off the list. You will never search for the same word twice, and the grid gets easier as it fills up.
Use a light pencil line or a loop rather than heavy marks. Words can share letters, and a heavy line can hide the letter another word needs. In the online player, you drag from the first to the last letter of a word, or tap the first letter and then the last, and the player marks the word for you.
The last word in a word search is always the one you have already looked past.
Step 7: Take a break, then use the answer key
When you have checked a word's rare letters, swept every line and still cannot find it, stop for a few minutes. A fresh look often lands on it straight away.
If it is still hiding, use the answer key for that one word only. Every puzzle on Word Search PDF has an answer key. The PDF has it on page 2, and the online player has a Show answers button. Look up the missing word, then close the key so the rest of the puzzle stays yours.
When these strategies are not what you want
The rare-letter trick works best on long words with unusual letters. A short word made of common letters, such as SEE or TEA, has no good anchor, so for those you are back to sweeping.
Speed is not the point for everyone, either. If you do word searches to unwind, a slow, wandering search may be exactly what you enjoy, and you can skip the method. For young children, finding words in their own way is part of the fun, so let them use only Step 6 and give hints sparingly.
Practise on a puzzle at the right level
Try the steps on an easy grid first, where words run only across and down. Once rare-letter scanning feels natural, move to medium puzzles with diagonals, then hard ones where backwards words are common. Our large print puzzles are a gentle start, and our hard word search puzzles test every step at once.

FAQ
How do I find words in Word Search?
Pick one word, find its rarest letter in the grid, and check the eight directions around every copy of that letter. If that fails, sweep the grid row by row, then column by column, then along the diagonals, reading both ways.
What is the trick to solving word search puzzles?
Search for the letter that appears least often in the grid, not the first letter of the word. Q, Z, X, J, K and V are the best anchors, and double letters such as LL or OO also stand out. Then follow each lead in all eight directions.
Is there a trick to word search?
Yes. Hunt for unusual letters and letter pairs, read backwards as well as forwards, and cross off each word as you find it so you never search for the same word twice.
How to solve a hard word search?
Expect diagonal and backwards words from the start. Work through the word list in order of the rarest letters, sweep the grid in strips with a ruler or a finger, and take a short break when you get stuck, because a fresh look often finds the last words quickly.
Conclusion
To solve a word search, pick the rarest letter in each word, check all eight directions from every copy of it, and sweep rows, columns and diagonals for the words that are left. Expect half the words in a hard puzzle to run backwards, mark each word as you find it, and save the answer key for the last one or two. With those habits, a grid that looked like a wall of letters becomes a short list of places to check.
