How to use: First, make sure you have at least one Starter Set. Then, assemble the Hammer, Tiptube, and Volcano action blocks as you like. Place marbles on the tracks and let them roll. Use the Hammer to give marbles a boost when they face obstacles. With the Tiptube, you can collect marbles and release them all at once for a fun effect. For the Volcano, when a marble hits its button, enjoy the eruption of new marbles. Note: Keep small parts away from children under 3 to avoid choking hazards. Make sure the blocks are placed on a flat surface for smooth marble movement. Maintenance: Wipe the blocks with a dry cloth if they get dirty. Don't use harsh chemicals as they may damage the blocks.
