Dewey's Dilemma Bookshelf


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.
Once you have solved the basic puzzle, there are more challenges ahead. For greater challenge, fix 2 books from the same author at both ends & the 3rd book at a fixed internal position. In other words, the books of this author that you have chosen cannot be moved. You must find a way to move all the other books to satisfy the 3 variables noted above. Upon solving that, change the position of the 3rd book. It creates a whole new puzzle to solve. There are in fact 7 positions that you could move this book to.
Then , change the 2 books on the ends and repeat the process. There are 21 sets of unique combinations that can be attempted.
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. The puzzle measures about 5.5" x 2.8" x 2" when assembled into the bookshelf.
Difficulty: 3 out of 5
