Brain Games Picture Puzzles #8, How Many Differences Can You Find? tests your powers of observation. Part of the popular Brain Games series, the book is packed with picture puzzles that challenge your mind. Each puzzle has two or more pictures that seemingly are identical, but subtle changes have been made to one of the pictures—it's up to you to find the differences.

The picture puzzles feature a variety of colorful indoor and outdoor scenes, from familiar classroom, office, and home scenes to exotic locales like the Grand Palace in Bangkok and Venice's Grand Canal. The puzzles are grouped into four levels of difficulty, each progressively harder. The differences become more subtle, the number of changes increases, and the pictures are more densely detailed. Solutions are provided in the final section of the book; the original picture is presented, with the changes circled and numbered.

Brain Games Picture Puzzles #8 is spiral-bound and handy to use, no matter whether you are at home, on public transportation, in a long security line at the airport, or relaxing at poolside or on the beach. Take along the book wherever you go—stimulate your mind a few minutes at a time.
