The objective? To arrange the books so that the top shelf is perfectly level. But you can only use certain books, in certain orientations, with a minimum of 2 books touching the top shelf at any time. Oh, and leave some room for a little black cat!
Today, I’m reviewing By The Book, a stacking puzzle for ages 8+ (Brainwright, $18). The game consists of 40 challenge cards, 12 wooden books, 2 wooden shelves, 1 plastic cat, and 1 balance level made to look like an adorable red flower pot.
To play, select a challenge card (which are graded as beginner, intermediate, advanced, or expert). The face of the card tells you which books you can use, if they need to be placed horizontally or vertically, or if they can’t touch at all. Sometimes, the card will require the cat to be included on the shelf as well. The back side of the card has the solution. Here are a couple examples of card faces and solutions:
Once you’ve gathered all the relevant pieces, lay the bottom shelf on a level surface, then try configuring the books to the card’s specifications. Put the top shelf in place when you think you’re done, then place the balance level on top to see if your solution measures up. And remember – a minimum of 2 books much be touching the top shelf at any time.
If your solution passes the level test, flip the card over to see if matches the official solution (and the rules do mention there may be other ways to solve the challenge). Some of the solutions, however, are not what you expect! Look at this creative configuration!

When playing this game, it’s important to work on a level surface. If your work table is tilted, you’ll never reach a solution. So use the level to make doubly sure you’re nice and even before you start playing.
So, what did our kid testers (ages 6, 8, and 10) think of By The Book? They loved it! The game requires analysis, trial & error, testing, and re-testing, but it’s very calm, non-competitive, and you can take as long as you like to reach the solution. By The Book is labeled as a 1 player game, but our kid testers found ways to collaborate. The cat adds a nice touch, and the kid tester found it very satisfying to put the level on the top shelf to see if their clever arranging worked!

By The Book is the best (a “bestseller,” if you will). It’s fun, intelligent, works with a large age range of kids, and the pieces are really nice quality. This would be a terrific classroom chill-out activity, the perfect addition to library game nights, or an awesome gift from that super cool librarian aunt or uncle. Plus, it comes with a CAT! Five out of five stars.
I use hot glue. A lot. And the projects on this blog? 99.9% of them use hot glue in some way, shape, or form. Hot glue is the perfect solution when you don’t have much time, but need something to stick quick. The drawback, of course, is that hot glue guns need to be plugged into an electrical outlet in order to operate.
So the LED light wasn’t very useful. Mostly, it allowed me to take cool pictures like this:
It all started when Marissa ask me if I wanted a shower notepad. Whaaaat? It turns out that, yes, there is a writing device specifically designed for the shower. Intrigued, I donned my black beret and turtleneck and headed to the bathroom to pen some poetry on the Aqua Notes Waterproof Notepad.
Aqua Notes retails on Amazon for $8. The set includes a 40 sheet pad that’s perforated for easy tearing, and an “aqua pencil.” The pad (which is 3.5″ x 5.25″) has two suction cups on the back. The pencil has a suction cup holder as well.
Ripping the pages off the notepad, however, was considerably more difficult than a regular pad. You had to line up the perforation just right. Unintentional bonus for those of you composing long poems – the wet pages stuck to the walls of the shower like a felt board. They stayed up there too! Pages stuck to my shower wall at 1pm were still going strong at 9pm. I removed them, noting that they peeled off easily and left no marks.
In terms of hardware, the suction cups held up well. For two weeks, the notepad clung to the wall, even after my kids discovered it and were sliding it, pulling it, and enthusiastically illustrating on it. Their testing efforts also revealed that once an individual page is removed from the shower, it takes about 45 minutes to completely dry.
And just in case you are wondering:
