What is a Mechanical Puzzle Book?

In 2016, an young man studying Industrial Design at Iowa State University decided to create the first ever mechanical puzzle book as part of his Senior Thesis Research Project. What he did not expect was the sheer amount of attention, publicity and support he would receive to make this thing a reality. Ever since, thousands of Codex Silendas have been cut out, assembled, and shipped all over the world! Even Romania!

How does it work?

It's a series of wooden, laser cut puzzle pages that must be solved in order to unlock and progress to the next page. As you progress through the puzzles, a story is revealed on the back of each page, providing hints and clues as to how one might solve the next incoming puzzle. We even offered five unique Themes & Stories to pick and choose from, each featuring unique engravings and storylines while the puzzles remain the same. The best part is you can even store things inside and re-lock the book up to have family and friends give it a go!

But wait... there's more?! After spending the last seven years refining our techniques, materials, and assembly & design processes around the Codex Silenda, we were able to develop what we are now calling the 2nd Generation in Puzzle Book Technology, aka the Quest Compendium. The Compendium is everything the Silenda could never be, featuring a level of customization and interchangeability not seen since the Rubrik's Cube!

How Long does it Take to Make?

Depends on the Puzzle Book you desire. The Codex Silenda is a very tedious and time-consuming puzzle book to cut-out and assemble, whereas the Quest Compendium is much faster and easier to build simply due to the new techniques and processes used in it's creation.

If you're ordering a Codex Silenda,

it will take roughly 2-3 weeks for us to cut it out, assemble it, and ship it out.

If you're ordering a Quest Compendium,

it will take roughly 1-2 weeks for us to cut it out, assemble it (or not!), and ship it out.
