Buying guide
A good puzzle book for adults gives you a steady climb: easy enough to start with a cup of tea, hard enough that the last pages still take some thought. This guide covers what to look for, which kind of puzzle suits which person, and the two printable packs we make for grown-ups.

Most disappointing puzzle books fail on the same few points. Check these before you buy any book, printed or printable.
Sudoku is a logic puzzle. There is no maths involved: you place the digits 1 to 9 so that none repeats in a row, column or 3 by 3 box. It rewards concentration and patience, and a hard one can take an hour.
Word search is a pattern-finding puzzle. It is gentler and more familiar, and most people can pick one up and put it down without losing their place. Many solvers keep both and choose by mood: sudoku for focus, word search to unwind.
| Sudoku | Word search | |
|---|---|---|
| Skill | Logic and deduction | Scanning and spotting |
| Feels | Absorbing, challenging | Calm, familiar |
| Typical time | 10 to 60 minutes | 10 to 20 minutes |
| Best if you | Like a challenge | Want to relax |
If you are new to puzzles, start below your level so the first few pages go well. Our sudoku pack opens with fifteen Beginner puzzles that give 40 numbers at the start, which leaves plenty of easy openings. The large print word search needs no experience at all.
Print size is the most overlooked part of a puzzle book. Our large print word search uses bold letters on a well-spaced 13 by 13 grid, one puzzle to a page, and both packs print in black on white for the strongest contrast. Because they are PDFs, you can also print at a larger paper size if your printer allows it.
A printed book is a single copy: once a page is done, it is done. A printable pack is a file you keep. You can print one page for the train, the whole pack for a long weekend, a fresh copy when a puzzle goes wrong, or a second set for someone else in your household.
Searching for puzzle books near you is often about speed. A printable pack is faster than any shop: the download opens the moment payment goes through, and you can print at home, at work or at a library.
Every puzzle in our packs is generated and then checked by computer before it is allowed into a pack. Anything that fails a check is thrown away and replaced.
One route per maze
Every maze is a perfect maze, so there is exactly one way through.
One solution per sudoku
Each sudoku is solved by computer and kept only if it has one answer.
Every word once
Each word-search word is checked to appear exactly once in its grid.
Answers included
Every pack ends with a full answer key, in A4 and US Letter.
The best one is the one matched to the solver. Pick sudoku for someone who enjoys logic and wants a challenge that grows, and large print word search for someone who wants a calm, familiar puzzle. Either way, insist on graded difficulty and an answer key.
No. Sudoku uses digits as symbols. There is no adding or multiplying, only working out which digit fits where.
Yes. Every pack ends with a full answer key, so a parent, teacher or the solver can check the work.

After checkout you download a PDF in both A4 and US Letter. Print it on any home, office or school printer, single or double sided. Ordinary printer paper works well for pencil.
Yes. For personal and classroom use: print as many copies as your household or class needs. You may not resell the files or the printed pages.
