Our SmartKidsPlanet initiative began in 2017 when 3 geeky and dedicated parents saw a gap in the children’s toys and games market. An opportunity was spotted while we struggled to find toys and games for our kids which enriched their minds and guided them toward science, art, math and construction. The trio then knew that their paths were set, establishing an online shop with a comprehensive range of intelligent toys for babies, children and young teenagers.

With offices based in California, our SmartKidsPlanet team enjoys a daily growth in our presence within the children’s educational toys market. We love our new place in life, and we love helping young minds with their growth and skill development, all while having as much fun as possible.

Fun stem

Toddlers enjoy building and taking apart the train.

Great train toy for a train loving child

A perfect hands on toy for a child who loves trains. My son loves building things and loves trains even more. This has been one of our sons favorite Christmas gifts he got this year.

Son loves it, mostly just the taking apart aspect.

Great train for our toddler

The train is great, it has a bunch of extra screws that dont fit in the train to use as cargo for the train that is a nice extra touch. There are not a lot of pieces like some of the other versions, but this was perfect for my toddler with the light and sound

Grand son loves this train its easy for him to put together and take apart. Jus wish it had a case to keep it in. Lots of parts are easier to scatter about.
