I bought this because I wanted something to do besides scrolling before bed. I figured I'd color for ten minutes and move on. Instead, I got completely hooked on watching the mystery image appear. There's something oddly satisfying about filling in the sections and slowly realizing what you're revealing. Now I leave the book on my coffee table and reach for it almost every evening. It's relaxing without feeling boring, and I usually end up spending less time on my phone without even trying.

I have only one word.. OBSESSED!! I color 1 to 2 pictures every night, before I go to bed, to unwind and I absolutely love watching the mystery picture come to life. The pictures that I’ve completed so far I would say range between beautiful and absolutely ADORABLE!! I don’t want to ruin it for anyone so I won’t say what the pictures actually are lol.

I bought this thinking it would be a simple colour-by-number book and somehow it turned me into a confident, unstoppable colouring machine.Designs: You start with random shapes and numbers, and suddenly BOOM actual pictures appear. It feels like solving a mystery with felt-tip pens.Variety: The mix of squares, triangles, hexagons, and circles keeps it interesting. No two pages feel the same.Black backgrounds: These make the colours pop like crazy. Even my lazy shading looked intentional and dramatic.Relaxation factor: 10/10. My brain went quiet. My stress left. My responsibilities were ignored (worth it).Paper quality: Thick enough that my pens didn’t bleed through and ruin my masterpieces.Time value: I sat down for “five minutes” and lost an entire evening. No regrets.Overall, this is part puzzle, part art, part therapy. If you want something relaxing, satisfying, and weirdly addictive, this is it.

Colouring squares and triangles has proven to be incredibly satisfying. This activity serves as a fantastic way to unwind after a tiring day spent wrangling a three-year-old and juggling various tasks. The "mystery image" concept introduces a touch of intrigue, making it feel less like tackling a children's activity book and more like revealing some artistic secret (even if the secret does turn out to be a cat). The black backgrounds really make the colours pop, and the combination of simple and more intricate pages allows me to choose something suited to my mood.That being said, there are a couple of minor issues. The numbers are so small that they can be difficult to see, even while using reading glasses, and deciphering certain colour names such as "yellow-orange" can be a little tricky. Additionally, placing a piece of cardboard behind the page is helpful to prevent any marks from transferring onto the next one.It’s an enjoyable and relaxing way to indulge in some creativity.

Saw a recommendation for this on Instagram and thought I'd give it a try - I'm so glad I did! Yes, the pages are thin but anyone who buys colouring books knows to put a sheet of card behind the page before using pens. It's fun to watch the picture spread as you add more colour and try to guess what the picture might be. Highly recommend this as a wind-down activity.
