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.

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.
