Tips for solvers
- Do the first puzzle together and say each step out loud: “Ava’s pet is not the cat, so I put a cross here.”
- Use a pencil so mistakes can be rubbed out.
- Once 3×3 feels easy, try the 4-item puzzles on the printable logic puzzles page.

Questions people ask
What age are these logic puzzles for?
Most children can solve a 3×3 grid from about age 7 with help, and on their own from about 8 or 9.
How do I explain a logic grid to a child?
Every person has exactly one of each thing. A cross means “definitely not”, a tick means “yes”. When a row has two crosses in a 3×3 block, the last square must be the tick.
How do I print without the answers?
Untick "Print answers" before printing. Answers are on a separate page, so you can also just print page 1.
Can I make my own instead?
Yes. The logic puzzle maker makes new puzzles with your own settings in a second.
