Printable puzzles: what works on paper and what doesn't

Not every puzzle survives the jump to the page. Which ones work on paper, which lose the point, how to pick the difficulty for whoever is going to play, and how to put together a weekly booklet.

There's a question hardly anyone asks before printing a stack of puzzles: which ones survive on paper. Because not all of them do, and it's easy to end up with twenty sheets nobody will touch.

The difference isn't a matter of taste. It's a property of the puzzle itself.

The rule: if the puzzle answers back, it isn't for paper

A puzzle works on paper when all the information is on the sheet from the start and doesn't change. If the puzzle needs to react to what you do — a timer, a sequence that's shown then hidden, clues that get revealed — paper can't do it.

That rule sorts them out on its own:

They work perfectly

Sudoku. The ideal case: fixed grid, single solution, verifiable without help. Paper even helps, because pencilling candidates into the corners is more comfortable than on a screen.
Word search. Circling with a pen is more satisfying than dragging a finger, and there's no risk of marking the wrong thing by slipping.
Crossword. It was born on paper, in 1913. It's still its natural format.
Murder sudoku. A deduction grid with the clues alongside asks for paper, because you want to cross things off and see the whole table at once.
Riddles. All they need is the wording and somewhere to hide the answer: the back of the sheet.

They lose the point

Memory. It's impossible: the whole puzzle consists of showing you something and taking it away.
Timed arithmetic. You can print the sums, but without a clock it isn't the same exercise.
Word guessing. It needs to tell you whether you were right after each guess.
Connections. It lives on limited guesses and immediate feedback. On paper it becomes something else.

How to pick the difficulty for whoever is going to play

This is the mistake that wastes the most sheets: printing whatever seems normal to you.

For older people. Start easier than you think and build up slowly. And the most important thing isn't the difficulty, it's the size: a grid that takes up half a sheet won't do, however simple the puzzle. One sheet, one puzzle, large print.

For children. Word searches on themes they recognise, and 4×4 or 6×6 sudokus long before 9×9. A classic sudoku frustrates a seven-year-old not because of the logic but because of how many cells they have to hold in their head.

For a classroom or a group. Print the same puzzle for everyone and a single answer sheet for yourself. If everyone has a different one, there goes the conversation, which is usually half the fun.

For a waiting room or a journey. Things that can be abandoned half-finished without losing anything. A word search can be put down and picked up; a long crossword, less so.

Four printing details worth getting right

One puzzle per sheet. Fitting two on to save paper is exactly what makes the grid small and the puzzle uncomfortable.
Black and white, no backgrounds. Coloured backgrounds eat toner and make pencil marks harder to read.
Answers on a separate sheet. Not at the foot of each puzzle. If they're underneath, the eye finds them.
Save the PDF, don't print blindly. Print two or three and see how the level is going before you run off twenty.

A weekly booklet that actually gets used

What works best isn't a block of thirty identical sudokus, it's variety and a rhythm. A formula that works well for seven days:

3 sudokus of rising difficulty (one easy, one medium, one hard)
2 word searches on different themes
1 deduction mystery, for the weekend, since that's the one that takes longest
1 answer sheet, folded and kept separately

That's eight sheets a week, stapled in the corner, and it lasts all seven days without anyone getting bored of the same thing.

Where to get them

The printables section has all three ready as PDFs, free:

Printable sudokus in easy, medium and hard, all with a verified single solution — which is not something to take for granted: there are generators out there that produce grids with two possible solutions, and that isn't a sudoku.
Printable mysteries, deduction cases with their clues and their grid.
A word search generator where you enter your own words and it builds the grid. That's useful for making them to measure: vocabulary in a foreign language, family names, a class topic.

And for word lovers, there are printable arrow words in three levels, one grid per page with the answers kept separate. If you have never done one, start with what arrow words are and how to solve them.

Large-print worksheets to print

And if you are printing them for an older person, there are large-print collections with a single sheet per page so it never feels crowded:

Cognitive activity sheets: word searches, proverbs, sequences, sums, opposites and 4×4 sudokus.
Memory activities, with reminiscence and orientation.
Attention exercises: letter cancellation, odd one out, mazes and copying shapes.
Maths worksheets with money, telling the time and a till receipt to check.
Reality orientation worksheets: the calendar, special days, the four seasons and putting things in order.
Word games: complete the words, words that mean the same, what’s the word and words beginning with…
Spot the difference, counting shapes, following paths and symmetry.
Reminiscence activities: memories of the 1950s to the 1980s, things from the past and old jobs.

And if you'd rather have a screen after all

Paper wins on concentration, on sharing, and on not needing to carry anything. Screens win on instant correction, on variety, and on never running out.

You don't have to choose. Plenty of people use their phone during the week and the booklet on Sunday. If that side interests you, there are free online puzzles and a comparison written for anyone playing alongside parents or grandparents in puzzles for older people.

And if you want to try all fourteen puzzles with nothing to install, they're in the web version.
