If you are like me, you probably have a million random LEGO© Duplo all over the house. We have Duplos from probably a dozen different sets and would love to use them for something else like marble runs. Luckily, you can buy marble run sets to use your existing LEGO© Duplo collection with. We purchased the COUOMOXA 110-piece set and loved it so much that we bought a second set to make longer and more intricate marble runs.

What is Included in COUOMOXA 110-piece Set
This set is the perfect set to get started with. It has plenty of pieces to make endless builds. Especially when you combine them with your existing LEGO© Duplo collection, pretty soon you won’t know the difference between the blocks since they all fit together snuggly to make complex marble runs.
Four colorful plastic marbles are included. These can be a choking hazard for your youngest builders. When my children were younger, I put them aside until I could sit with them and try the marble runs they built.
The set includes two green baseplates and numerous other components to build your marble runs. The instructions include several step-by-step example builds to get you and your young builder started. All these builds were completed and added to our Marble Run Expert YouTube channel.
So Many Possibilities
The vibrant colors that LEGO© Duplo come in keep children entertained to build marble runs. Watching my son figure out how to design a marble run so that the marbles do not lose momentum is impressive. Every day, the builds get bigger and bigger as he learns different design concepts to maximize the space and pieces he has available.
One of the best parts is that you can use standard-size marbles on this set, although none are included. The fun part about marble run sets is that you can create marble runs using different sets and run them into each other. You can use a tube to get your marbles started, and after running through your LEGO© marble run, you can move into a homemade cardboard marble run or anything else you can think up.
