Review: Excellent puzzle - This puzzle is so great! I loved putting it together over a few days for me. Very relaxing and offered a nice challenge. Really great if you love gradient puzzles.
Review: Great puzzle! - If you want a fun and super unique Gradient puzzle than this puzzle is for you, it is my favorite puzzle I have ever done. But I do not like challenging puzzles and I only do Gradient puzzles, so it was kind of made for me. It is not difficult by any means so if that is what you are looking for I don’t think you will like it. Ramblings- As someone who loves Gradient puzzles I will say this, the Gradient spreads throughout the whole puzzle which is awesome, no giant chunks of one color. When there is only one color, the puzzle pieces are so unique and follow such a logical layout that it isn’t an issue. I also really appreciate the color selection. A lot of Gradient puzzles are mostly one color group, like a certain one I dislike that is almost completely red orange and yellow with a tiny corner of purple/pink. I strongly dislike the color yellow so I appreciate that yellow isn’t as dominant in this puzzle as some others, and the colors have a cool toned pastel vibe to them which is nice. The green going into the yellow isn’t the ugly chartreuse that every other puzzle uses but a cool mint color. This is definitely my favorite puzzle I have ever done, and if they came out with the same puzzle type and cut but with 1000-1500 pieces and the same Gradient (maybe without the yellow) I would pay mad money for that

### ⭐⭐⭐⭐ Easier krypt than single color
*by T***S on January 11, 2026*

They give you a cheat sheet with the puzzle shape layout. When I did the magenta krypt I had to cheat a lot. With this one, because it’s a gradient, I never even looked at the cheat sheet, making for a much more enjoyable puzzle, and certainly less challenging than the single color krypt. I did find the green section harder to tell apart than the rest. All in all, enjoyable, but I prefer gradients that have the standard puzzle cuts. This cut didn’t really satisfy me. The cut is kinda hodgepodge and not visually pleasing when it’s done. It comes off as a gimmick as opposed to something aesthetically designed. So if you want to try a krypt this gradient is definitely easier than a single color, if you’re just looking for a gradient there are better choices.
