The quality of the plastic and connectors is excellent. We’ve built and rebuilt the same set many times, and it still feels brand new.

Priya Nanda, San Jose, CA

We gave an Engino STEM kit as a birthday gift — it completely outshined the other toys! It keeps our son engaged for hours while teaching him valuable skills.

Ali Khan, Toronto, ON

The instructions are super clear and visual. My 8-year-old was able to build models all by himself within minutes. Great confidence booster!

Sarah Thompson, Chicago, IL

We tried several robotics kits before this, but Engino stands out. It’s not just plug-and-play — kids actually learn how the parts work.

Awesome gift for my pre teen nephew. He loves it and constantly builds new things. I particularly like the booklets that come with the toy. As an educated adult, I still learned some things from the item, lol. Wish there were more things like this when I was a kid

FAQs

What is the appropriate age to play with ENGINO?

The ENGINO system has been tested with children with the association of teachers and the department of Education of the University of Cyprus. It has been found that small models can be built even by 5 years old children. Bigger and complex models are more suited to 8-12 year olds, and our robotics and mega sets are targeting both youngsters and grown-ups as being more hobby items.

What if I lose some parts or manuals? Can I get replacements?

You can buy parts, instructions and books at a very low price from our online shop.

How is the quantity of parts compared to value for money?

Usually construction toys refer to the number of parts contained in a set as an indication of the set's building value. With ENGINO system this reference does not actually apply because the system is unique and the design of the parts allows multiple connectivity in all directions at the same time. As a result, there is no need for intermediate connectors between rods while ENGINO rods are also connectors! The ENGINO system can be described as a combination of the brick system and the spatial "connectors and rod" system. As of that, with ENGINO to build a model you only need around half the parts that you would require with any other conventional system! Furthermore, as ENGINO parts are bigger, the model is also bigger and more manageable. Parts are not easily lost and sets can combine together to create an infinite number of builds. Because the "number of parts" is actually misleading, we have introduced a new term called "connecting points" that indicates how many connections are possible with the particular parts contained in each set.
