This five-page book contains a series of wooden puzzles rather than a long story.
Called the 'Codex Silenda: The Book of Puzzles," the volume was designed by Brady Whitney and contains five different puzzles on each of its pages. Each of the puzzles work as bolts and once one has been solved, another is unlocked for the user to figure out. The book also reveals a brief story line in which the person unlocking the wooden puzzles must do so because they have to capture spies in order to protect Da Vinci's work.
Rather than functioning as a simple game, the Code Silenda can be used as a decoration and turns solving puzzles into a noteworthy experience.
