There’s a reason square and triangle magnet toys are so popular – there’s so much you can do with them!
At SUPA STEM, we love finding new ways to have fun with our Magnet Builders. With any set of magnetic shape blocks, there are literally hundreds of things you can build.
In general, we find our own kids can happily play and come up with their own creations for hours and hours (giving us plenty of time for a nice cup of coffee…or to join in and get creative ourselves!).
However, sometimes kids can need a little bit of inspiration to get their creative juices flowing.
That’s why we’ve put together this mega list of 63 magnetic block ideas that your kids will absolutely love! Check them out and be sure to bookmark this page to come back to whenever you need it.

63 Fun things to build with magnetic blocks
When it comes to any building blocks toys, having more pieces obviously allows kids to build bigger and more complex structures. If you currently have a smaller starter set at home, you might want to expand it to widen the possibilities.
Whichever magnetic kids blocks you currently have, just make sure that when it comes to purchasing more you opt for shapes that are compatible with all the major brands.
Whether you already have a bunch of magnetic squares and triangles at home or you’re just starting your collection, there are plenty of model building ideas here for sets both large and small!
We’ve also organised them by theme so you can quickly locate the designs you think your kids will love best.
