Marble GeniusMarble Maze Slides Set: 30 Building Blocks, and 60 Challenge Cards, with Instruction App Access - 3D Puzzle and Logic Game - Build, Race, and Discover Tracks with This Marble Game Set

Our 6, 8, and 10 year olds have loved this marble puzzle. The plastic is thick and durable for them to work with quickly and the directions are easy to follow.I find that my children always play best with a toy or game if I play with them first and help then navigate it. Once the first few levels are mastered, the challenge is On :)

Purchased this for my 8 yr old grandson for his birthday and he loves it.

Works well and the challenge cards make it fun for kids.

Great activity to use with older kids who loved marble run games.

Great fun for my 5 and 8 year olds!

We love it!

My newphew loves it!!

Talk about a fun toy set. I like it because it gets kids thinking and building and it's such a joy yo see them so excited when the marble runs through. Our grand kids have already spent hours building the mazes and starting all over. Great toy to keep kids busy and using their brains. We can never give them enough brain exercises.I think it's a little pricey for plastic, but I guess it's worth it when they get so much joy out of it. There are also add-ons to this set, so you can keep it going, and going and going.Nice toy with hours of fun.
