A very fun game for 18 months through 24 so far. Very good quality, a great gift.

Awesome way to get kids interested in connectivity and science. There are lots of different configurations and challenging puzzles that are possible. The puzzles to be solved (on cards) range from easy to expert.

A great gift for my 7-year-old grandson. Bought for my 8 year olds birthday & perfect for him. My 8 yo very much enjoy the product!

The dominos are weak. It is hard to know if you haven't completed the puzzle or if the pieces are just not properly fitted in place. Dominoes fall crookedly, not right, it turns out very rarely!
