What are these puzzles?
They are picture puzzles, not word puzzles: no spelling, no general knowledge, no maths beyond counting. You look closely, compare and find something. The free sample has one puzzle of each kind, all at the easy level:
- Count the squares and count the triangles: count every shape, of every size.
- Odd one out: all the shapes point the same way except one, which is flipped.
- Hidden letter: one letter in the grid is different from the others.
- Spot the differences: find the 3 changes between two grids.
- Odd color: one square is a slightly different shade.
- What comes next? Find the rule and pick A, B, C or D.
- Optical illusion: which line is longer?
- Matchstick equation: move one match to make the sum true.
- Cube nets: which flat shape folds into a cube?
Why people like them
We keep this honest: these puzzles are for enjoyment, and we make no medical or health claim. What we can say is what readers and reviewers of picture puzzle books tend to ask for, and what we built the sample around:
- Easy to start: no rules to learn and no words to know. Each puzzle has a one-line instruction.
- Large print and high contrast: big pictures and big type, so you do not need a magnifying glass.
- Answers you can trust: every answer is at the back, with a short explanation, and each one was checked.
- Different kinds and levels: ten kinds of puzzles, so it does not feel like the same page over and over.
- Nice to share: they work well for two, for example a grandparent and a grandchild, or a carer and the person they spend the afternoon with.
How to use the free PDF

Frequently asked questions
Are these puzzles really free to print?
Yes. The sample PDF is free, with no sign-up and no email address needed. You can print as many copies as you like for yourself, your family or a group, as long as you do not sell them.
Are the puzzles in large print?
The free sample is: one puzzle per US Letter page, with big pictures, big type (30-point questions) and plenty of white space. It also prints well on A4. The paperback is 6 × 9 inches with one puzzle per page, so the pictures are large, but it is not sold as a large-print edition.
Are the answers included?
Yes. Every puzzle has its answer at the back, with a short explanation, so nobody gets stuck. Each answer was checked before publication.
Do I need a color printer?
Most puzzles work in black and white. The Odd Color puzzle needs color, so print that page in color or solve it on a screen.
Will these puzzles improve memory or prevent memory loss?
We make no medical or health claim. These are puzzles for enjoyment: they ask you to look closely, compare and think, and many adults simply like that kind of challenge. For questions about memory or health, talk to a doctor.
