Unlike The Maze and other classic puzzle books, the Codex Silenda brooks no cheating, forcing readers to solve elaborate puzzles on each page before proceeding to the next.

Somewhere between a choose-your-own-adventure novel, a Chinese puzzle box and a blacksmith puzzle, this five-page volume features dizzyingly complex mechanical puzzles that can only be completed in sequence. In each pair of facing pages, a short story unfolds on one side while a related new puzzle is revealed on the other.

Designed by Brady Whitney, the wooden book is laser-cut and ornately detailed, full of hidden mechanisms worthy of Leonardo Da Vinci – indeed, the story itself is about an apprentice stumbling into the master’s workshop and becoming trapped inside the tome. The laser-burnt edges give the work a hand-crafted but careworn look, like something you might find in a mysterious antique shop, covered in dust.

From the makers: “Codex Silenda is a five page book that features five intricate puzzles. Each page features a unique puzzle that requires the user/reader to unlock the corresponding bolts in order to progress to the next page.” More about its maker: “Brady Whitney is the designer of the operation, the mastermind of the Codex. He originally came up with the idea for his senior thesis research project during his final semester at Iowa State University. Having grown up with a childhood filled with imagination, his passion for design has always been focused on the realm of toys and games, creating the products and ideas he always wished he had as a kid.”
