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.

It satisfies the Room/DaVinci itch better than most, but it does fall flat in some areas. Puzzles are either too simple or so finely hidden that you need to use a hint to point out an obscure detail you missed. The ending was severely lacking. Would have appreciated a choice between completing the grand task and risking the consequences or backing out & staying safe. Considering the game's underlying theme, it would've worked well. Still... worth the price of admission.

Revised opinion of this game. still 5 stars for gameplay, graphics, and puzzles. 3D not cartoon like, and puzzles still take some thought to figure out. I decided to purchase full game because I really liked this one. However, deciding if it's worth the money vs what more you get is challenging. Yes, you get 3 more levels with all the puzzles on each level, but the puzzles and levels aren't too difficult to complete and the game is over quickly. Should be more for your money IMO.

Absolutely amazing & creative graphics, themes, effects, sounds. My mouth literally hung open as some of the results played out on the screen! Achievable puzzles ... quite intuitive & easy to navigate, but still requires skill and persistence. This is now my favorite puzzle game of all time. Seriously.
