Nick Volt · Puzzle books for children
Logic puzzle books that teach kids a method.
Story-led puzzle books for children who would rather solve something than fill something in. Every new trick is shown step by step before your child tries it alone, and every puzzle has exactly one answer.

Try the trick Robi teaches
This is Puzzle 7 of the book, exactly as it is printed on page 18. Tap a square where you can be sure of the shape.
Robi's Rule #2: Every row, column and box has each shape once.
- Circle
- Triangle
- Square
- Star
Start with a line that has only ONE empty square.
That was Puzzle 7 of 70. It has exactly one answer, and you never had to guess.
The seven steps
- Row 4 already has Square, Star and Circle. The missing shape is the Triangle.
- Column 1 already has Star, Triangle and Square. The missing shape is the Circle.
- Row 2 already has Circle, Triangle and Square. The missing shape is the Star.
- The top-left box already has Star, Circle and Triangle. The missing shape is the Square.
- Row 1 already has Star, Square and Circle. The missing shape is the Triangle.
- Column 2 already has Square, Triangle and Star. The missing shape is the Circle.
- Row 3 already has Triangle, Circle and Star. The missing shape is the Square.
For parents and teachers
Built so a child never has to guess
Shown before it is asked
In the comics, Robi works through one example on the page, step by step. In the museum, a box explains each new kind of puzzle the first time it turns up.
One answer, reached by thinking
Every puzzle is checked by a computer program before it goes into a book, so no child loses an afternoon to a puzzle that had no answer, or had two.
Harder a little at a time
Comic puzzles climb from one star to three. The museum's rooms get harder as the night goes on, and the book says so.
