Book of Secrets UGEARS 3D Wood Puzzle

Age: Our puzzles have a 14+ mention on the boxes. For this model we still recommend from 12 years old accompanied by an adult

Lock your secret notes, treasures, or other personal items in the Ugears Book of Secrets and keep them away from prying eyes. This beautiful 3D wooden puzzle is a book-shaped steampunk combination box with a secret compartment, a multi-step opening sequence, and fascinating mechanical action. Your Book of Secrets opens with a three-digit combination on the back of the book to release the secret key. Insert the key into the special slot and turn it counterclockwise to engage the opening mechanism, then turn the gears counterclockwise to open the book. Various windows on the box let you know if you've completed each step correctly. This secret 3D mechanical box, with its intricate opening sequence, holds many mysteries and is both a fun way to store your belongings and a fun game to play with friends or family as they challenge them to discover the hidden features of the Book of Secrets. For the first time in Ugears' history, we have used two colors of plywood (dark and light) to make this model even more special for you.

Books have been used to hide objects, in real life and in fiction, for almost as long as books have existed. Homeowners can hide valuables from burglars by hollowing out a book and placing it on a shelf with other books. The secret book is easy for the owner to find, but almost impossible for the burglar to find. In "The Matrix," Neo hides computer disks and money in a book, and who can forget the escape from prison in "The Escapees," carried out with a hammer hidden in a Bible, the pages of which are cut out of the Exodus. Everyone loves puzzles and riddles and this Ugears secret book is just a big puzzle with a series of puzzles to solve to open the secret compartment and see what's inside!

You can set any three-digit combination on your Ugears Book of Secrets by removing the pin block inside the secret compartment. Turn the dials to the desired combination and reinsert the pin block. The key release mechanism will then work with your chosen combination. When you press the lever under the bottom of the book's spine, the key pops out of its slot at the top of the spine. The lever will not eject the key if all three cylinders are set to a different sequence of numbers. You can reset the three-digit combination at any time by following the same sequence: open the 3D wooden box, remove the pin block, reset the combination, reinsert the pin block, and the key release mechanism is now set to the new combination.

Forgot the wetsuit? Oh no, now what? Don't worry, our designers and engineers have you covered. There are two different ways to access the contents of the box without the combination. You can open the Book of Secrets by simply detaching the back panel. Insert a flat tool like a screwdriver or metal ruler into the slot between the back panel and the box, then gently pull the panel in several places to lift and remove it, allowing you to access the box. You can now reset the combination to get a three-digit code that's easier to remember. You can also play Vault Cracker by discovering the combination by touch. Press the key release lever with your finger, holding it down slightly, then rotate each cylinder one after the other. You'll feel that the right number on each drum spins a little tighter than the others, and the lever moves slightly under your finger when the right number clicks into place. When the last cylinder is set to the correct number, the indicator on the edge changes from closed to open. The unlock key is now engaged.
