100 Perceptual Puzzles
There are 100 stimulating, challenging, and delightful geometrical puzzles in this book. They are put together by Pierre Berloquin, author of many game books- card and board games, tarot card games, intelligence games, solitaire games, party games, and a few `non-game' books. He has also written three other puzzle books that contain numerical, logical, and alphabetical problems.
