PLUS PLUS Building Blocks Puzzle by Number Unicorn set (STEM logic build for kids 5+)
Product description
Key takeaways
This PLUS PLUS “puzzle by number” unicorn set is built around a familiar idea: match numbers to colours, but with Plus Plus building blocks instead of traditional paint or printed pieces. The selling point, on paper, is the creative loop—make a display piece for a bedroom wall, then later take it apart and reuse the blocks for other builds.
It also leans into skill-building. The included guide is designed to help children fill in the design, and the process uses fine-motor steps that can keep hands busy for longer than a typical single-stage craft. The set is positioned as STEM learning resources, with the makers also describing it as suitable for sensory engagement. Not everything will land the same for every child, though, if your child prefers free-building with no step-by-step pattern, a numbered format may feel a bit limiting.
What matters most
A big part of deciding whether this is worth it is whether you want a “build once, then reuse” approach. Here, there’s no glue required to create a striking unicorn design to display. When the novelty wears off, you can make and break apart to re-use the Plus Plus pieces for other projects, which is a practical advantage compared with one-off jigsaws or craft kits that get filed away.
The puzzle-by-number mechanism is straightforward: you use the enclosed pattern and match each number with the corresponding colour. That makes it easier for kids to understand what to do next, especially if you’re supervising and want something more structured than open-ended blocks.
Is it perfect for all budgets and all learning styles? Probably not. As with any kit, the experience depends on attention span and willingness to follow a guide. If you’re expecting a highly complex adult-level build, this one is more “kids crafts” than “serious modeller territory”.
Where it shines
This set ticks several boxes that parents usually look for in bedroom-accessory crafts.
First, it’s designed to be displayable. The idea of building a unicorn piece that can live on a wall gives the craft a clear purpose beyond “finish and tidy”. Second, it’s described as easy to clean. The blocks are BPA- and phthalate-free, and the guidance suggests you can wash in a washing machine or dishwasher, which is genuinely useful if the set will be handled often.
Third, it’s built around Denmark manufacturing and tested to EU safety standards. That doesn’t remove the need for normal supervision with kids’ toys, but it’s an important reassurance if you’re comparing safer-material-focused sets.
What to check before you buy
Before buying, it’s worth checking how your child tends to engage with number-based crafts.
If they enjoy following a pattern and matching colours, this should feel approachable. If they get bored with step-by-step instructions, you may find they lose interest halfway through. Also consider that, while the blocks are described as washable, you’ll still want a bit of practical organisation—kept together, pieces accounted for, and the guide kept somewhere safe so the next build doesn’t start from scratch.
One more limitation to keep in mind: the description doesn’t mention storage components or how the pieces are bagged, so it’s sensible to look at the images on the listing to see how the kit is organised.

Is it worth it?
It’s worth buying if you’re looking for a kids’ STEM craft that combines a clear step-by-step goal (puzzle by number) with the satisfaction of building from Plus Plus pieces, and you like the idea of turning it into a bedroom accessory. A solid pick if your child enjoys colour matching and following a guide, and you want something they can repeat through re-building rather than a one-time craft.
You may want to skip it if your child prefers fully open-ended construction without instructions, or if you’re after a complex adult-style build challenge. It might not be a great match if you know they tend to lose patience during multi-stage activities—numbered puzzles are only as engaging as the child’s tolerance for the process.
