Introduction
Welcome to the official book of the 100% Logique television show. This book is designed to engage your observation skills, logical thinking, and cognitive functions through a series of progressively challenging questions. It offers an interactive experience for individuals or groups, focusing on pure logic rather than general knowledge. Prepare to test your mind and discover if you possess the unique logical aptitude required to solve the most complex puzzles.
Getting Started
Before you begin your logical journey, ensure you have a comfortable and quiet environment. While the book is self-contained, having a few items handy can enhance your experience.
- Writing Utensil: A pen or pencil for jotting down thoughts or solutions.
- Scratch Paper: For complex problems, a separate sheet of paper can be useful for calculations or diagrams.
- Timer (Optional): If you wish to simulate the show's competitive aspect, a timer can be used to track your response times.

How to Play
The book is structured to guide you through various logical challenges. Each section presents questions designed to test different aspects of your logical reasoning and observation.

Solutions are typically located on the reverse side of the page or in a dedicated section, allowing you to check your answers after attempting each puzzle. Use these resources to learn and improve, rather than as a first resort.
