US Version

"No books can go left of the brown book." So this means it must touch the far-left side.

UK Version

If there are no books to the left of the brown one, the chances are it goes on the far left of the shelf.

US Version

The third and fifth rules tell you how to arrange the yellow, white, and purple books. From left to right, put them in exactly that order.

UK Version

The third and fifth clues reveal how to line up the yellow, white and purple books. From left to right, put them in the following order: yellow, white, then purple.

US Version

The second and fourth rules should give you a good idea about where to place the blue book. However, if all of the books are placed vertically, you'll never solve this puzzle.

If you keep this in mind, you'll find there's only one place you can put the blue book...

UK Version

From the second and fourth clues, you should be able to deduce where the blue book goes.

However, if you're trying to stand all the books vertically, it will be impossible to meet all the conditions. Take away this constraint and there's only one place you can put the blue book...

US Version

Following the rules and put all of the books into the bookcases except for the blue one. Now see that space along to top? Turn the blue book sideways, and it will fit right in!

UK Version

If standing all the books upright doesn't work, try putting one in sideways.

When you put all except the blue book in, can you see a space at the top? That's where the blue book goes.

## Solution

### Incorrect

US Version

As long as the conditions are met, it doesn't matter how you arrange the books.

UK Version

Remember, it doesn't matter how tidily the books are arranged as long as you meet all the conditions.

### Correct

US Version

Book smart!

Placing the blue book sideways at the top is the key.

UK Version

That's right!

Placing the blue book horizontally on top of the others makes it work.
