Interactive Marble Run Set Marble Rush - Racing Set M200 E with 69 components, a launcher sound and light module, and 5 printed MarBalls (balls). The electronic launcher sound and light module releases multiple MarBalls simultaneously when the flag barrier is pressed down and triggers cool effects when the MarBalls roll out or through.

There are countless building options and pathways with curves, ramps, and secret passages (blocks with holes). The horizontal launcher accelerates the MarBalls. Building and playing with the marble run enhances motor skills, creativity, spatial thinking, and understanding of the principle of cause and effect.
