This is a unique logic puzzle with a number of challenges. For the basic challenge, arrange the 12 books so that there are no consecutive numbers, no books of the same author, & no books of the same height next to each other. Thus, you have 3 variables that you must keep track of to solve the puzzle. There are 4 different authors on the books (3 books for each author), with the name and title laser engraved into the books. Each author's books are of a different hardwood and easily distinguishable. The books are all made of 1/4" thick wood so they are quite substantial and virtually unbreakable. With the laser engraving feature they will last more than a lifetime. Once you have solved the basic puzzle, there are more challenges ahead - 21 sets of unique combinations can be attempted and are included with the puzzle.

Great fun of a realistic challenge for most people and even children down to age 8. Also a terrific teachers gift puzzle, or a desk or coffee table type puzzle as it looks really good and is something that is not intimidating and will appeal to many different types of folks.
