Marble Run Building Blocks with 6 Balls, 179 Pcs Big Castle Building Toy Set Compatible Classic Blocks Maze Track, Marble Runs for Kids 4-8, Stem Learning Toddler Toys Gifts for Boys Girls Kids

My 2 year old loves this set. He is always excited to see the ball run and loves to drop balls and watch them roll down. As parents, we love that the toy is not only fun, but also educational as toddlers can learn about cause and effect. It also encourages them to use their imagination, when they start using the bricks for their own creations. This toy can not only be a ball run, it can become a playground, a house, a garden, a farm.... it is compatible with Duplo, so my toddler brings his Duplo animals over to play on it. I can see this toy keeping his interest for a long time. Highly recommended!

This set is super fun. Kids and adults love it. I wish there were more pieces that twisted the other way. Makes it hard to make a long slide because it folds back on itself so much- needing more height and long straight pieces. Also I think the house walls are AWESOME! but I got two of the same kind- so they don’t fit together.

We absolutely loved this set! Yes, we! My kiddo and I have spent so many hours building different landscapes with this set and it hasn’t gotten old! The little characters it comes with are adorable and the accessories are perfect! It never gets old. Go buy it… Thank me later!

I have all kinds of Duplo toys for my preschool girl. She plays with them all the time at home. This set gives us a lot of fun, especially she likes the sound when the ball rolling in the plate. It comes with two "brick" walls, and we use it along with other walls came from other Duplo for a big castle. Thus, we didn't exactly follow the instruction to build the track, but it still works fine.

Edit: set not actually incomplete. It had two bad steps in the instructions. Set was incomplete and I couldn’t find a way to contact the seller. We had to finagle the pieces to make the marble run. We ran out of some 2x2 pieces that the instructions said to use, so we improvised. The 5 year old is still having fun with it, so it was still a good present.
