The Great Brain Vault

A Puzzle Adventure with Professor Puzzle

by Ezequiel Fernandez

Step into a puzzle adventure with Professor Puzzle as your guide. The Great Brain Vault invites curious kids ages 8–12 to explore twelve mysterious chambers, sharpen six different puzzle skills, and take on the vault’s toughest final challenge.

Inside are 200 puzzles to work through, including:

  • 34 word searches
  • 34 sudoku puzzles
  • 33 criss-cross puzzles
  • 33 word scrambles
  • 33 mazes
  • 33 hangman games

From the Brain Warm-Up to curious collections, evidence trails, and far-flung destinations, each section adds to the adventure. The variety lets young puzzlers switch between searching, solving, unscrambling, navigating, and reasoning—keeping minds engaged as they explore.

Whether children enjoy independent challenges or puzzle time with family, this book offers plenty to discover. A table of contents makes it easy to find a section, and a how-to-use page helps readers get started. When a puzzle needs checking, all 200 solutions are collected at the back.

A lively gift for curious kids who enjoy brain-teasers, problem-solving, and an imaginative adventure alongside Professor Puzzle.
