I had so much fun completing this puzzle! It was very challenging to keep my brain thinking the whole time but I couldn’t put it down! Wish I could do it again all over. Can’t wait to do more!!

I was given the ECD - 002 to work at and enjoyed it so much that I immediately booked an escape room because I wanted the fun to continue! Challenging enough but the leaps of logic weren’t too big to want to give up. The materials were well made and felt sturdy. Keen to try another!!

The puzzles are amazingly presented, all white and smooth, very enjoyable to pick up and interact with. Despite being not great at physical puzzles these were very satisfying -- every step felt natural and there were a few surprises! More puzzles please!

Still working on completing the full trilogy. I’m taking my time because the puzzles are so cool I don’t want to rush to the finish. Presentation, packaging is all top notch. Definitely stands out.

I knew as soon as I opened my package that I would love all of these puzzles. Visually, they are simple and clean looking, and you would swear there was not going to be any complexity to them at all. Yet, once you dive in, there is just enough intrigue to keep you going without forcing a rage quit. Loved them!

Unreal puzzling experience. All 3 boxes are amazing, top to bottom. Exactly the right amount of difficulty so that you have to stop and think, but not so hard that you get stuck forever. Highly recommend and can't wait to see what Nick comes out with next.

The puzzles aesthetically amazing; so simple. However, they are deceivingly challenging. One piece I only unlocked by accident when by how I set one down. Keep me busy for a decent time and were easy enough to reconstruct for the next challenger.

Unbelievable. Once i started i couldn't stop until i was finished. As good as if not better than some of the best escape rooms i've done. Loved the different challenges and mechanisms across the boxes. 10/10

I love the pure, clean stark visuals of this trio [or quartet, really].

I was hoping for a slightly greater challenge that would have taken me a bit longer to solve, but it's a wonderful set that proceeds from easier mechanisms to some more advanced in the end.

As such, it's perfect for perhaps presenting to a room full of non-puzzling friends! Maybe they'll get sucked in.

Speaking of getting sucked in, I was a big fan of the story / written elements in the ECD, which are the cards at the outset but little else, sadly. I would have liked more! But that just goes to show, it must have been good, if I wanted more. :}

Had a blast solving these puzzles. Very clever and well made!

The puzzles were so much fun. I love the packaging, it keeps the puzzles all together and is great for displaying. Can't wait to see what the next puzzle!

My kids and I love the puzzle set. They had a blast solving them.

I'm still pretty new to puzzle boxes, but I've tried several and these have been the most interesting and fun. I struggled a bit with the first one, but once I had a basic idea of what to expect, the others were more straightforward (but still challenging). These had some clever mechanisms and puzzles and they were very well made!

I had never purchased a puzzle like this before. Most of them have all been the laser cut wood ones
but I took a chance and dedicated the money to purchase this set. I'm so grateful I did. The puzzles are challenging, but not foreboding. It's a very tactile sequential discovery puzzle made from the 3D printed parts to the mechanics all lead to a highly durable puzzle. I hope we dont have to wait 2 years for another offering from NP. And thank you as I no longer have to lie to my wife as to what it is. I just say "oh it's Nothing"

I got #90, just in time for Christmas, and perhaps all of us uncles neglected our families too much because of it. These three puzzles are fantastic -- compelling, aesthetic, and really well-made. The suggested timing was pretty much spot-on, and I appreciate that it can be reset (and there's come room for a prize or something at the end). Each of the trilogy had a different vibe, and all were a challenge. They unfold in awesome ways.

My only issues were that one (and only one!) stage of one the puzzles didn't quite land -- which, out of how many stages is a feat -- and that the story materials took an "ancient artifact" theme, when these bad boys are clearly from the future.

I very much look forward to the next set of puzzles, and that the creator has much success!
