Fully illustrated in colour, here is a bonanza of mazes, word games, visual and logic puzzles and more. With a full range of difficulty, but all totally solvable, the puzzles are not meant to be tests. In fact they're engaging and humorous, as fun to work on as they are satisfying to solve. In Gray Matter, readers first solve a short crossword, then use the letters in the puzzle to crack a riddle. Hot Lines involves matching kids to their clothing- based on tan lines. Flea Circuit is an unusual maze that you find your way out of by jumping around the page like a flea. A scavenger hunt runs through the book, solve every puzzle to amass the clues and earn the bound in certificate of achievement.
