About this game

Boxes: Lost Fragments is a 3D puzzle escape game in which you solve complex mechanical puzzles, discover hidden objects, and unveil a dark mystery!

As a legendary thief, your next assignment lures you into a grand and lavish mansion. There, you find a series of puzzle boxes designed for an unknown purpose.

Soon, signs begin to emerge that you are no longer in control of what is unfolding and perhaps never were. You start to doubt if this is an ordinary residence or a containment facility of some sort. What should have been a quick in-and-out gradually turns into your own harrowing struggle for freedom and answers.

Inspired by the cryptic atmosphere, intricate machinery, and smooth controls of the best room escape games, we have created a diverse set of original puzzle levels that will test your resolve and skills to navigate this mysterious and compelling journey. Each level is beautiful, unique, and a true delight to explore and figure out.
