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.

Pas indispensable

La bǫte de d̩marrage suffit, cette bǫte est tr̬s bien mais pas indispensable. Autant acheter les petites pi̬ces sp̩ciales comme le marteau par exemple.

Meglio dell'espansione building

Mio figlio voleva pi_ esagoni e ma dalle descrizioni ci siamo accorti che l'espansione "trax" ne ha pi_ dell'espansione "building" e mio figlio ̬ stato molto soddisfatto dell'acquisto.

La pista di biglie 2.0

The media could not be loaded. Abbiamo regalato questi set della Ravensburger in occasione del compleanno di nostra figlia (11 anni), su sua specifica richiesta.Devo dire che la qualit del prodotto mi ̬ piaciuta, seppur fatto in plastica (i pezzi) e cartone (la base) con le biglie in metallo (incluse) ha una semplicit d'uso che rende il bambino protagonista del gioco, senza dover per forza chiedere aiuto ad un adulto.I pezzi si incastrano l'uno con l'altro molto facilmente e si possono creare infinite combinazioni di gioco gi con lo starter kit.Ovviamente acquistando le diverse appendici avremo un gioco maggiormente coinvolgente e piste sempre pi_ performanti.In pratica ̬ la pista di biglie 2.0Il prezzo non ̬ altissimo e l'esperienza di gioco risulta educativa e divertente al tempo stesso.Un gioco diverso da regalare o da regalarsi.
