It will keep your child busy for hours
My 5 year old loves creating chain reactions. This was a wonderful Christmas gift. Even though an adult supervision is required, you must allow the kids to read the book and create their own chain reactions. I was surprised to see my 5 year old go step by step and build the machines. Of course, you need extra Lego's This is just an addition.

Very few pieces. But this works with most other Lego pieces and good work for the brain to try create, record different types of reactions.

Easy to follow instructions and a variety of moving machines to work through. Would suit 9-11 years.

White bricks were not included in the box.
Today I got lego chain reaction toy and it has Few pieces in the box. Unlike the pictures they are showing here it doesn’t have white bricks. My son ended up with making only small structures.

Great product!
Totally worth it! Adds another dimension to Lego creations. Quality is good, and the pieces can be used in so many more ways if your child is so inclined.

Interesting and challenging Lego for the young builder or engineer in mind.
This was sent to my Grandson as a Xmas gift. He likes building and planning his project at a young age. He enjoyed the challenge of putting this together. It’s an interesting gift for boy or girl who like an engineering type of puzzle.

子ども達の目が輝きました☆
レゴ大好きな小2と年長の兄妹にプレゼントしたところ、表紙を見るなりピタゴラ装置だ!と大興奮。しばらく夢中で遊んでいました。 本はすべて英語で書かれていますが、大きな写真やイラストにインスピレーションが刺激されるのか言葉の違いは全く問題になりませんでした。普段遊んでいるレゴでちょっと違う遊びができて大満足です! 付属のレゴは少なめですが、手持ちのブロックがあるのであまり問題はありませんでした。それより、ビー玉サイズのボールがついていたり、レールになる厚紙がついていたのが良かったです♪

Well executed by the authors. Think about these things before purchase.
This was not an easy concept for the authors and product planners to execute. It's radically different than just assembling Legos from an instruction booklet. A lot of thought and effort went into the chain reaction concepts and resulting projects. The book layout, the security so that the parts actually arrive at the consumer, the durability of the non Lego paper components, the directions on how to fold the paper components etc, etc, etc. are thoughtfully done. I think they struck a very good balance so this would not cost an arm and a leg. Some might call it cheap (a few Lego pieces, a beautiful well laid out instruction book with nicely printed paper components) but I call it cost effective. A lot of what you're paying for here is in my opinion is the wow factor of the book and the well thought out concepts. I supported my 7 year old grandson's effort to build the first project. My 5 year old grandson looked at what was involved and walked away I think because it looks complicated and the projects contain very few pieces. Both of them are very skilled Lego builders who pride themselves on their ability to throw lots of pieces together quickly. Does that sound familiar to you? So... I think what motivates most young Lego builders is assembling lots of pieces quickly and having a relatively static object to play with when done. The chain reaction projects aren't that at all. They don't look like much -to an adult - when complete. They are challenging in my view mostly because of the need for precision alignment between the paper parts and the Lego motion actuators the kids assemble to create the Chain the Reaction. Once assembled and aligned, making it function can require trial and error, motivation to succeed, precision hand and eye coordination and patience. I think that doing the first project successfully might be a make or break point for this product. Failure would surely be a deterrent towards doing subsequent projects in the book so initial success seems very important at least for younger children. The greatest joy my grandson experienced (and it was great joy) was the moment the first project functioned properly for the first time after several complete and partial failures (just as his patience was wearing thin) and then joy again once the chain reaction was rehearsed and easily repeatable so as to show his parents without failure. Having achieved this first success he was excited about doing more projects. It remains to be seen what his long term interest level will be. Yes.. This is radically different than just sticking prices together and success is not easy considering that the projects are minimalist in the total number of pieces. However I think the lessons and skills this product teaches are very important, worthwhile and noteworthy. Aside from the skills mentioned above this is also elementary physics of motion, weight, angle, momentum, etc. In summary, it appears that, assuming success along the way, the complicated chain reactions are fun for children to assemble, challenging to make fully, reliably functional and thrilling once they work for that first time. It's all good stuff!
