These affordable roller coaster sets are fun to build and play. The mechanics/engineering encourages children to become interested in how things can be constructed.

Wow! Where to start? This is the most fun I’ve had building a set in quite some time. The personality is unmatched. Roller coaster, slushies, DJ, arcade, Easter eggs galore and an awesome color scheme!

This was perfect for my son. And entertaining for both of us. He loved the skill level and loves roller-coaster's so this was a good one. He plays with it daily.

The kids love it!

[This review was collected as part of a promotion.] My kids (9 and 13) had an absolute blast building this! We're a huge Lego family, so they jumped right in! They split the bags up so it was even, and they both were able to do fun steps. Like everything Lego, quality is amazing and the book had easy to follow instructions. The mini figs are super cute and they love how the heads are reversible so they can change their expressions. The rollercoaster is a lot of fun, and they both have really enjoyed playing with it in different ways! As always, Lego did a great job!
