Very Hard Word Search Printable: Six Rungs to Climb

You have finished every ordinary puzzle and none of them slowed you down. A very hard word search printable has a big grid, a long word list and words that run in all eight directions, backwards included.

A very hard word search printable is mostly a question of how much you have to look through. The words themselves can be ordinary. What changes is the size of the grid, the number of words on the list and how many ways a word can face.

Researchers who study how people find a target among look-alikes put it plainly. In his chapter on visual search, Jeremy Wolfe of Harvard Medical School writes that the more similar the target is to the distractors, the less efficient the search will be. In a word search the distractors are every other letter in the grid, and they are all from the same alphabet as your word.

Difficulty in a word search comes from what you have to look through, not from what you have to know.

What makes a very hard word search printable

Three things set the difficulty: the grid, the list and the directions. In our Hard Word Search line the directions never change. Every level hides words in all eight directions, so backwards and diagonal words are already there on the first rung. The grid and the word count are what climb.

So what separates very hard from ordinary hard? A smaller printable puzzle may hide words across and down only, on a grid you can take in at a glance. Large Print Expert, in our own lines, is 14×14 with 15 words. In this guide, very hard starts above that: a grid of 15×15 or more, 20 words or more, and eight directions every time.

You can measure a puzzle before you print it. Count the squares, count the words and divide. Here is the arithmetic for all three levels, drawn as a ladder.

Three rungs of Hard Word Search Rung 3: Expert 20 × 20 grid, 30 words, 400 squares, about 13.3 squares per word Rung 2: Tough 18 × 18 grid, 25 words, 324 squares, about 13.0 squares per word Rung 1: Tricky 15 × 15 grid, 20 words, 225 squares, about 11.3 squares per word All eight directions on every rung, backwards included

The squares-per-word figure is our own arithmetic from the grid and word count of each level. It is a rough guide, not a score. It shows that Expert gives each word a little more room to hide than Tricky does, and also puts 400 squares in front of you.

1. 15×15 with 20 words: the first rung

Start here if you finish ordinary puzzles in a few minutes. A 15×15 grid has 225 squares and 20 words to find. Every one of those words can face any of eight directions.

Backwards words can catch you out here. Your eyes are trained to read left to right, so a word running right to left slips past. Expect to read each row once forwards, then go round again hunting for words that finish where you did not expect.

2. 18×18 with 25 words: where scanning gets tiring

An 18×18 grid has 324 squares, nearly half as many again as Tricky, and five more words on the list. The difference you feel is stamina. You stop scanning with your whole page in view and start working in blocks.

Work one corner at a time. Find what you can in the top left, tick it off, then move on.

3. 20×20 with 30 words: the top rung

Expert is a 20×20 grid with 30 words. That is 400 squares to look through, and the level has 40 puzzles, so about 16,000 squares and 1,200 words in all. Plan on sessions of one or two puzzles.

Every puzzle PDF has its answer key on page 2, so the solution stays off the puzzle page until you turn to it. To see how the three levels feel, Hard Word Search in three levels has every puzzle free to play online or print in US Letter or A4.

Why do 400 squares feel so much harder than 225? Research at UC Berkeley's Whitney Lab describes visual crowding as the deleterious effect of clutter on object recognition away from the point where you are looking. In a dense grid every letter you are not fixed on is surrounded by other letters, and that can make it harder to pick out a word at the edge of your view.

4. Hunt for the last letter first

Backwards words are easier to find if you stop looking for the first letter. Pick the rarest letter in the word instead. Q, X, Z and J appear far less often than E or T, so there are only a few places to check.

Once you have a rare letter, look at its eight neighbours. If one of them is the letter that should come next in the word, you have a direction. Follow it. If not, move on. This turns a scan of 400 squares into a handful of short checks.

Words without a rare letter need a different approach. Try the last letter. Because a backwards word ends where a forwards word would begin, scanning for last letters finds the ones your eyes skip.

5. Add a clock to the same puzzle

When Expert stops slowing you down, do not look for a bigger grid. Reprint the same puzzle and set a timer. Note your time in the margin and try to beat it. Because each puzzle is a free PDF, you can print a fresh copy and race yourself on it.

Another trick is to cover the word list and look for the words you remember from your last attempt. Then uncover the list and check what you missed. It costs nothing and makes the same grid feel new.

For a harder version without a bigger grid, cover the word list completely and look only at the theme. Every one of our Hard puzzles has a theme, such as Rivers of the World in Tricky. Write down every word you can think of that fits, then hunt for them. Uncover the list at the end to see which ones you guessed. Our printed puzzles always come with the word list, so this is a way you play it, not a built-in mode.

6. Stop where very hard turns into just slow

Be honest about what a larger grid gives you. Past a certain size it stops being clever and becomes slow. A 20×20 grid is a long, patient hunt. Solvers who enjoy that can stay on the top rung. A solver bored by square 300 will be happier with a different kind of puzzle.

Our Hard collection stops at 20×20 with 30 words. Bigger grids are on other pages: the giant word search puzzles have 25×25 and 30×30 grids with 40 to 55 words, and the extreme word search puzzles are 22×22 with 36 words. The hidden message word search puzzles spell a phrase in the leftover letters. The Hard collection has no holiday sets either.

Printing a very hard puzzle so you can read it

A 20×20 grid is dense, so print it well. Choose "Actual size" (100 %), not "Fit" or "Shrink", so the page prints as designed. Use plain matte paper and good light, because glare makes crowded letters run together. A pencil with a soft point lets you circle without hiding the letters. If your eyes tire before square 300, that is a sign to drop to Tough or Tricky, not a sign that you are bad at puzzles. Pick US Letter or A4 to suit your printer. Every puzzle prints in both.

Is it too hard, or is the puzzle wrong?

Check in this order before you blame the puzzle. First, reread the word on the list and check the spelling you are hunting for. Second, remember that words can run backwards or diagonally, and read the row from right to left. Third, look at the answer page. In our puzzles every listed word is placed in the grid, and the answer key on page 2 marks each one. When you can see the word there, the puzzle was fine and the grid was hard. Cover the key and uncover it a few rows at a time first: the right row alone often ends the search.

Free to play or print

Every Hard Word Search puzzle is free. You can play it in your browser or print it as a PDF with the answer key on page 2, and you need no account, no email address and no app. Each level gives you 40 puzzles at one steady pace, the same layout every time, and levels to move up or down when a puzzle is too easy or too much.

To print a whole level in one go, each level is also one optional PDF of 40 puzzles with a contents page and an answer page for each, for $4.99, or $9.99 for all three. The same puzzles stay free one by one.

Will you give up? Match the rung to the person

People quit when the grid is too big, not when the words are too hard. Start on the rung where a puzzle still takes a few minutes. If you read the full answer line on most puzzles, step down a rung. If you never need a hint and finish fast, step up. Change one rung at a time. All three levels sit on one page, so moving between them takes one click.

How to choose a very hard word search printable

Pick the rung where a puzzle still takes you a few minutes, and climb when it stops. Use the table to find where to begin.

Conclusion

Very hard is a ladder, not a single leap. Start on the rung where a puzzle still takes you a few minutes, climb when it stops, and add a clock or the last-letter trick when the grid alone is no longer enough. If you want a printable to climb with, Hard Word Search has three levels of 40 puzzles, and every one is free to play or print.
