Kidoozie Mega Marble Madness

Turn playtime into a construction adventure with the Kidoozie Mega Marble Madness marble run set. Kids design and build their own gravity-defying racetracks, then send marbles twisting, looping, and dropping to the finish. With endless ways to combine the pieces, no two tracks ever have to be the same.

70 pieces, endless layouts: Mix and match spirals, drops, loops, and ramps to create a new track every time.

Builds up to 28 inches tall: Finished creations stand as an impressive centerpiece for any playroom.

3 colorful marbles included: Race them side by side and challenge friends or siblings to see whose track and marble win.

Hands-on STEM learning: Kids practice engineering, problem-solving, and cause-and-effect thinking as they test, tweak, and rebuild.
